If you rent out a property in England or Wales, the EPC rating of that property is no longer just a number on a certificate, meeting the minimum EPC rating directly determines whether you can legally let it. The Minimum Energy Efficiency Standards (MEES) have tightened significantly since their introduction, and further changes are coming. This guide sets out exactly where the rules stand in 2026, what landlords need to do, and what happens if a property falls below the required rating.

 

The Current Minimum EPC Rating for Rented Properties

Since April 2023, landlords in England and Wales must not let a residential property, under any tenancy type, if it has an EPC rating below E. This applies to:

 

• New tenancies granted after 1 April 2020
• All existing tenancies, including those that started before the MEES regulations came into force

 

In plain terms: if your rental property has an EPC rating of F or G and you currently have tenants in it, you are already in breach of the regulations unless you hold a valid registered exemption.

 

The rating threshold applies to the EPC lodged on the national register. If your property has an EPC that is less than 10 years old and rates E or above, you currently comply with the minimum standard.

 

What Changes Are Coming After 2026?

The government has consulted on raising the minimum EPC rating for rented properties to C. The proposed timetable, which has shifted several times, points toward a requirement for new tenancies to achieve an EPC C from 2028, with all tenancies required to meet C by 2030.

 

As of April 2026, final legislation confirming this timetable has not passed. However, the direction of travel is clear, and landlords who plan ahead now avoid the scramble, and the higher costs, that come with rushing improvements to meet a deadline.

 

A property rated D or E today may be legally lettable now but require significant investment within the next two to four years. Landlords with portfolios that include D and E rated properties should treat this as an active planning issue rather than a future concern.

 

Which Properties Need an EPC for Renting?

Almost all residential rental properties in England and Wales require a valid EPC. The requirement applies to the whole building if it is a single dwelling, or to each self-contained unit if the building contains multiple flats.

 

A small number of property types are exempt from the EPC requirement entirely:

 

• Listed buildings (where compliance would unacceptably alter the character of the building)
• Holiday lets used for fewer than four months a year
• Residential buildings used less than four months a year
• Standalone buildings under 50 square metres

 

Properties that fall within these categories do not need an EPC and therefore do not need to meet the MEES rating threshold. However, landlords cannot claim a building is listed or exempt without being able to evidence it, the exemption is a legal position, not just a preference.

 

What Happens if a Rental Property Fails the Minimum EPC Rating?

Civil Penalties

Local authorities enforce MEES and can impose civil penalties of up to £30,000 per property per breach. The penalty structure in England is:

 

Breach	Maximum penalty
Letting a property below the minimum rating	Up to £30,000
Providing false or misleading information on an exemption	Up to £5,000
Failing to comply with a compliance notice	Up to £5,000

 

Local authorities can also publish details of non-compliant landlords, which carries reputational consequences alongside the financial ones.

Tenants Can Report Non-Compliance for minimum EPC rating 

Tenants have the right to report their landlord to the local authority for MEES non-compliance. A tenant who suspects their property has an F or G rating, which they can check on the public EPC register at epcregister.com, can trigger an investigation without any formal complaint process.

Mortgage and Insurance Implications for failing the minimum EPC rating 

Some mortgage lenders require properties to hold a minimum EPC rating as a condition of the mortgage. Non-compliance with MEES can also affect buildings insurance if it comes to light during a claim or renewal. Landlords should check their mortgage terms and insurance policy wording.

 

How to Improve a Rental Property’s EPC Rating

The most effective route to a C rating depends entirely on what the property currently has and lacks. An EPC assessor’s report includes a list of recommended improvements with their estimated impact on the score. Common measures that move a property from E or D to C include:

Loft Insulation

If the loft has less than 270mm of insulation, topping it up is typically the cheapest and highest-impact measure available. A well-insulated loft can add 5 to 15 points to an EPC score.

Wall Insulation

For cavity wall properties, filling an unfilled cavity adds significant points and costs relatively little. For solid wall properties, external or internal wall insulation is required, more expensive but potentially moving the rating by 15 to 25 points.

Heating System Upgrade

Replacing an old gas boiler with a modern A-rated condensing boiler improves the rating. A heat pump delivers a larger improvement still under the current SAP methodology. Properties with electric storage heaters, common in older flats and converted properties, often rate poorly specifically because of the heating system.

Hot Water Cylinder Insulation

An uninsulated or poorly insulated hot water cylinder loses significant heat. A cylinder jacket costs very little and contributes to the EPC score.

Double Glazing

Single glazed windows drag the rating down. Replacing them with double glazing improves the score and reduces tenant heating costs, which matters for tenant retention.

Solar Panels Are a Great Way to Raise Minimum EPC Rating s

A modest PV system (2 to 4kWp) can add 10 to 20 points to an EPC and push a D-rated property to C. For landlords with properties in reasonable solar exposure, this is increasingly worth considering as panel costs have fallen substantially.

 

Grant Funding for Landlords

Landlords sometimes assume grant funding for energy efficiency improvements only targets owner-occupiers. That is not the case, private landlords can access funding through several routes.

ECO4

The Energy Company Obligation scheme funds energy efficiency improvements for fuel-poor and low-income households. Private landlords qualify where their tenants meet the eligibility criteria, typically receiving certain means-tested benefits or living in a property with a poor EPC rating. The works install at no cost to the landlord, but the tenant must give consent and the landlord must agree to the work.

 

ECO4 does not require the landlord to contribute financially, but the landlord must commit to not raising rent as a result of the improvements for a period after installation.

Great British Insulation Scheme (GBIS)

Targets properties in lower council tax bands or with EPC ratings of D or below. Landlords with eligible properties can access subsidised insulation through registered suppliers. The scheme funds one primary measure per property.

Boiler Upgrade Scheme

Provides grants of £7,500 toward the cost of a heat pump. Available to landlords as well as owner-occupiers. A heat pump installation on a property currently heated by electric storage heaters or an old gas boiler can transform the EPC rating.

 

A PAS 2030-certified, TrustMark-registered installer can assess which funding routes apply to each property in a portfolio and manage the applications.

 

MEES Exemptions: When They Apply and How to Register Them

Where a landlord genuinely cannot bring a property to the minimum EPC rating, MEES regulations allow for exemptions. These are not a way to avoid the rules indefinitely, they are specific, time-limited provisions for defined circumstances.

High Cost Exemption

Where the cheapest qualifying improvement costs more than £3,500 including VAT, and the landlord has explored all available funding routes, they can register a high cost exemption. The landlord must obtain at least three quotes and demonstrate that no grant funding covers the works.

No Improvements Possible Exemption

Where a qualified assessor confirms that no relevant improvement measures are technically feasible, typically in a listed building or a property where planning restrictions prevent wall or window improvements, the landlord can register this exemption.

Third Party Consent Exemption

Where improvement works require consent from a freeholder, leaseholder, or planning authority, and that consent has been actively sought and refused, the landlord can register this exemption.

 

All exemptions register on the government’s PRS Exemptions Register at gov.uk. Most last five years. Exemptions do not transfer to a new landlord on sale, the buyer must independently qualify.

 

Landlords should treat exemptions as a last resort rather than a first response. Many properties that appear to qualify for a high cost exemption actually qualify for funded improvements through ECO4 or GBIS that remove the need for an exemption entirely.

 

Practical Steps for Landlords in 2026

Check every property’s current EPC rating. Search the EPC register at epcregister.com. If any property rates F or G, it needs immediate attention. If properties rate D or E, plan now for the likely future requirement to reach C.

 

Commission a new EPC if the existing one is over 10 years old or if significant improvements have been made. An outdated EPC may not reflect the current state of the property, particularly if loft insulation, glazing, or heating has been upgraded since the last assessment.

 

Get improvement surveys done before the price rises. As the 2028 deadline for new tenancies approaches, demand for assessors, installers, and materials will increase and prices will follow. Landlords who act in 2026 and 2027 secure better pricing and better availability.

 

Check grant eligibility for each property. A single conversation with a registered installer often reveals funding that a landlord did not know was available. ECO4 in particular funds improvements that landlords assume they would need to pay for themselves.

 

Document everything. If you register an exemption or fund improvements, keep records of quotes, survey reports, grant applications, and completion certificates. Local authority enforcement officers can request evidence.

 

Frequently Asked Questions

Does MEES apply to HMOs?

Yes. Houses in multiple occupation require an EPC for the whole building. Each self-contained unit within a larger property also requires its own EPC. Both the building-level and unit-level ratings must meet the minimum standard.

 

What if my tenants refuse access for improvement works to meet the minimum EPC rating ?

A landlord who cannot carry out improvements because a tenant refuses access can register a temporary exemption while demonstrating they have taken reasonable steps to obtain consent. The landlord should document all attempts to arrange access in writing.

 

Can I sell a non-compliant property to another landlord?

Yes. MEES compliance obligations attach to the tenancy, not the sale. However, a buyer taking on a non-compliant tenancy inherits the compliance problem, which affects the property’s value and saleability. Most informed buyers discount F and G rated rental properties significantly.

 

Does a higher EPC rating justify a higher rent?

There is no legal basis for charging higher rent solely because of an EPC rating. However, lower energy costs benefit tenants in more efficient properties, which can help with tenant retention and reduce void periods.

 

How do I find out what improvements would take my property to a C EPC Rating?

Commission an EPC assessment. The assessor’s report includes a table of recommended improvements, each with its estimated impact on the score and approximate cost range. This gives you a clear roadmap from the current rating to C.

Information correct as of April 2026. MEES regulations and proposed changes to minimum EPC standards are subject to ongoing legislative development, check the latest government guidance or take professional advice for your specific portfolio.

Most properties require an Energy Performance Certificate when sold, let, or built. But a small number of property types fall outside this requirement. This guide explains exactly which properties qualify for an EPC exemption, how landlord exemptions work under the Minimum Energy Efficiency Standards (MEES), and what you need to do to register one.

Which Properties Are Exempt from Needing an EPC?

The government sets out the following categories of property that do not require an EPC.

Listed Buildings

Listed buildings in England and Wales do not require an EPC where meeting the minimum energy efficiency standards would unacceptably alter their character or appearance. Historic England and local conservation officers often restrict or prohibit measures such as external wall insulation, double glazing, or solid floor insulation in listed properties.

However, this exemption is not automatic. The owner must be able to demonstrate that compliance measures would genuinely harm the building’s heritage significance. A blanket assumption that all listed buildings qualify is incorrect.

Temporary Buildings

Buildings with a planned useful lifespan of less than two years do not require an EPC. This covers temporary structures such as site offices, pop up retail units, and seasonal buildings erected for a fixed short term purpose.

Residential Buildings Used Less than Four Months a Year

Holiday homes and other residential properties that owners use for fewer than four months per year, and where energy consumption falls below a relevant threshold, qualify for an exemption. The owner must be able to evidence the low and seasonal nature of use.

Small Standalone Buildings

Standalone buildings with a total useful floor area of less than 50 square metres do not require an EPC. This covers garden studios, small outbuildings converted to habitable use, and detached garages with a basic amenity fit out.

Industrial Sites, Workshops, and Agricultural Buildings

Non residential buildings that do not use energy to condition the indoor climate, meaning no heating, air conditioning, or mechanical ventilation, do not require an EPC. Agricultural barns, unheated storage warehouses, and similar structures fall into this category.

Places of Worship

Buildings used exclusively as places of worship and for religious activities qualify for an exemption.

Demolition

Where a seller or landlord can demonstrate that they have all the necessary consents and permissions to demolish the building, and that the buyer or tenant is aware of this intention, the property does not require an EPC.

EPC Exemptions for Landlords Under MEES

Separate from the general EPC requirement exemptions above, the Minimum Energy Efficiency Standards (MEES) create a distinct set of exemptions relevant specifically to landlords.

Under MEES, landlords in England and Wales must not let a property with an EPC rating below E. From April 2026, the government has confirmed that the minimum standard for new tenancies will rise, with further increases planned. Landlords who cannot meet the required standard may register an exemption on the PRS Exemptions Register.

The No Improvements Possible Exemption

A landlord can register this exemption where a qualified assessor or surveyor confirms that the property has no relevant energy efficiency improvements that are technically feasible to install. This might apply to a solid wall property in a conservation area where both external and internal insulation are prohibited or impractical.

This exemption lasts 5 years, after which the landlord must reassess whether improvements have become available.

The High Cost Exemption

Where the cheapest improvement measure costs more than £3,500 (including VAT), and the landlord cannot fund the works through third party funding such as ECO4 or the Great British Insulation Scheme, the landlord can register a high cost exemption.

The landlord must obtain at least three quotes from qualified installers to demonstrate the cost, and must show they have explored all available funding routes before relying on this exemption.

The Third Party Consent Exemption

Some improvements require consent that the landlord cannot obtain. Common situations include:

• A freeholder or head lessor refusing consent for works in a leasehold property
• A local planning authority refusing permission for external wall insulation in a conservation area
• A listed building consent refusal

The landlord must evidence that they actively sought consent and the relevant party refused. Simply not applying does not qualify.

The Recently Let Property Exemption

A landlord who purchased a property that was already let to a tenant, and where the property does not meet the minimum EPC standard, can register a six month exemption while they take steps to bring the property into compliance. This gives the landlord time to either carry out improvements or register a longer term exemption if one applies.

The New Landlord Exemption

A person who becomes a landlord through inheritance or other means not involving a commercial purchase may register a six month exemption while getting the property assessed and any relevant works arranged.

How to Register a MEES Exemption

Landlords register exemptions on the government’s PRS Exemptions Register at gov.uk. The process requires:

1. Creating an account on the register
2. Selecting the type of exemption that applies
3. Uploading supporting evidence (assessor reports, quotes, consent refusals, planning decisions)
4. Confirming the property details and EPC rating

The register is publicly searchable. Local authorities use it to check compliance when investigating complaints or conducting proactive enforcement. Landlords who let a property without a valid EPC or exemption face civil penalties of up to £30,000 per property.

Exemptions do not transfer when a property changes ownership. A new landlord buying a property with a registered exemption must independently qualify for their own exemption or bring the property up to the required standard.

Do EPC Exemptions Affect Grant Eligibility?

Yes, in some cases. Grant schemes such as ECO4 and the Great British Insulation Scheme use EPC ratings to determine eligibility. Properties with very low EPC ratings (E, F, or G) often qualify for fully funded improvements.

If a landlord registers a MEES exemption instead of carrying out improvements, they may miss out on funded measures that would otherwise be available. Before registering an exemption, landlords should check what funding they can access through a TrustMark registered, PAS 2030 certified installer, as grants can cover the full cost of works and remove the need for an exemption altogether.

Frequently Asked Questions

Does a listed building always qualify for an EPC exemption?

Not automatically. The exemption applies where compliance with energy efficiency requirements would unacceptably alter the character of the building. Many listed buildings can still accommodate improvements such as loft insulation, secondary glazing, or draught proofing without harming their character. Owners should take professional advice rather than assume an exemption applies.

Can I sell a property without an EPC if it qualifies for an exemption?

Yes. If your property genuinely falls within one of the exempt categories, you do not need to commission an EPC before marketing it. However, you should be prepared to evidence the exemption to solicitors and buyers during the transaction.

How long do MEES exemptions last?

Most MEES exemptions last five years. The recently let and new landlord exemptions last six months. At the end of the exemption period, the landlord must reassess whether improvements are now possible or fundable before re registering.

What happens if I let a property without a valid EPC or exemption?

Local authorities can issue civil penalties of up to £30,000 per property. They can also issue compliance notices requiring landlords to carry out improvements or register a valid exemption within a specified timeframe.

Can a tenant report their landlord for not having a valid EPC?

Yes. Tenants can report non compliance to the local authority, which has enforcement powers under MEES. The local authority can investigate and issue penalties where appropriate.

Do I need an EPC for a holiday let?

Holiday lets used for fewer than four months a year may qualify for an exemption from the standard EPC requirement. However, if you let the property through a short term platform and it is available for more than four months a year, you likely need an EPC. The rules for holiday lets in relation to MEES are also subject to ongoing legislative change, check the latest government guidance for your specific situation.

Sign up as an assessor

Information correct as of April 2026. EPC regulations and MEES standards are subject to ongoing legislative change. Always check the latest government guidance or take professional advice for your specific circumstances.

An Energy Performance Certificate (EPC) is a legal requirement for most properties in the UK when they are sold, let, or built. This guide explains what an EPC is, what the ratings mean, when you need one, how to get one, and what you can do to improve yours.

 

What Is an EPC Certificate?

An Energy Performance Certificate (EPC) rates the energy efficiency of a building on a scale from A (most efficient) to G (least efficient). It also provides an estimated annual energy cost for the property and a list of recommended improvements with their potential impact on the rating and running costs.

 

EPCs are produced by accredited Domestic Energy Assessors (DEAs) following a standard methodology set by the government. The assessment covers:

 

• The construction of walls, roof, and floors
• Heating systems and controls
• Hot water provision
• Lighting
• Ventilation
• Windows and glazing

 

The assessor collects data on site and enters it into approved software (SAP: Standard Assessment Procedure) which calculates the EPC rating.

 

EPC Ratings Explained

Rating	Band	Description
92 to 100	A	Most efficient
81 to 91	B	Very efficient
69 to 80	C	Above average
55 to 68	D	Average
39 to 54	E	Below average
21 to 38	F	Poor
1 to 20	G	Very poor

 

The UK average EPC rating is D (around 60 points). Most pre 1920 solid wall properties score E, F, or G without significant energy efficiency improvements.

 

The EPC also shows a potential rating, the score achievable if all the recommended measures were implemented. This is useful for understanding the gap between current and best case performance.

 

When Do You Need an EPC?

An EPC is legally required in England and Wales when a property is:

 

• Sold: the seller must commission an EPC before marketing begins and provide it to the buyer
• Let: landlords must have a valid EPC before marketing a property to tenants
• Newly built: developers must provide an EPC on completion

 

You do not need an EPC if you are remortgaging (rather than selling), making improvements only, or if the property is exempt (see below).

 

EPC validity: An EPC is valid for 10 years. If your property has an EPC on the register that is less than 10 years old, it can be used for a sale or letting without commissioning a new one, though if significant improvements have been made, it may be worth getting a new assessment to reflect them.

 

EPC Requirements for Landlords

EPC rules are particularly important for landlords. Under the Minimum Energy Efficiency Standards (MEES) regulations:

 

• Since 1 April 2020, landlords in England and Wales cannot grant a new tenancy for a property with an EPC rating of F or G
• Since 1 April 2023, all existing tenancies must also meet the E rating minimum, including properties where no new tenancy has been granted

 

A landlord with an F or G rated property must either:

 

1. Carry out improvements to bring the rating to E or above, or
2. Register a valid exemption

 

Proposed tightening of MEES: The government has previously consulted on raising the minimum to C for new tenancies from 2026 and all tenancies from 2028. As of April 2026, final legislation has not been confirmed, but landlords should plan on the basis that a C rating will eventually be required and begin improvements accordingly.

 

EPC Exemptions

Some properties are exempt from EPC requirements. Exemptions include:

 

• Listed buildings (where compliance measures would unacceptably alter the character of the building)
• Temporary buildings intended to be used for less than 2 years
• Residential buildings used less than 4 months a year
• Standalone buildings under 50m² of useful floor area
• Industrial sites, workshops, and agricultural buildings not modified for residential use

 

For landlord exemptions under MEES, where a property genuinely cannot reach an E rating cost effectively, a formal exemption can be registered on the PRS Exemptions Register. Exemptions must be renewed every 5 years and are not automatically inherited by a new landlord.

 

How to Get an EPC

An EPC can only be produced by an accredited Domestic Energy Assessor. You can find accredited assessors on the government approved register at the EPC Register website (epcregister.com) or through accreditation bodies including:

 

• Elmhurst Energy
• Stroma Certification
• ECMK
• Sterling Accreditation

 

The process:

 

1. Book an assessment with an accredited DEA
2. The assessor visits your property and takes measurements and notes on construction, heating, and services (typically 30 to 60 minutes)
3. The assessor enters the data into SAP software
4. The EPC is produced and lodged on the national register
5. You receive a copy of the certificate

 

All EPCs are lodged on the publicly accessible EPC Register where you can look up any property in England, Wales, or Northern Ireland.

 

How Much Does an EPC Cost?

EPC costs in 2026 range from around £60 to £120 for a standard domestic property. Prices vary by:

 

• Property size (larger properties take longer to assess)
• Location (assessor availability affects pricing)
• Whether the EPC is standalone or part of a package with other services (e.g., conveyancing, energy audit)

 

For newly built homes, the EPC is typically produced as part of the building regulations compliance process and may be included in the developer’s handover documentation.

 

EPC Ratings by Property Type

Average EPC ratings vary significantly by property type and age.

 

Property Type	Typical EPC Band
New build (post 2010)	B or C
1990s to 2000s semi detached	C or D
1960s to 1980s terrace	D or E
Pre 1920 solid wall terrace	E or F
Victorian detached, unimproved	F or G

 

Properties with gas central heating, double glazing, and loft insulation typically rate at D or C. Properties with solid walls, electric storage heaters, and single glazing often rate at E, F, or G.

 

How to Improve Your EPC Rating

The EPC itself includes a list of recommended improvements ranked by impact and cost effectiveness. The most impactful measures for typical UK properties are:

Loft Insulation

One of the cheapest and highest impact measures. Properties with uninsulated or under insulated lofts (below 270mm) benefit significantly. Can move a rating by 5 to 10 points.

Wall Insulation

For cavity wall properties, cavity fill insulation makes a major difference. For solid wall properties, external or internal wall insulation is required. Wall insulation can move an EPC by 10 to 20 points or more.

Heating System Upgrades

Replacing an old gas boiler (G rated efficiency) with a modern condensing boiler (A rated) improves the EPC. Moving to a heat pump produces an even larger improvement under the current SAP methodology.

Double or Triple Glazing

Replacing single glazed windows with double glazing is reflected in the EPC calculation and improves the rating.

Solar Panels

Photovoltaic (PV) panels are increasingly common and can add 10 to 20 points to an EPC depending on system size and the property’s energy demand.

Heating Controls

Installing a programmer, room thermostat, and thermostatic radiator valves (TRVs) contributes to the rating. Smart controls may be captured in future SAP versions.

 

EPC and Property Value

EPC ratings increasingly influence property values. Research by various estate agents and property consultancies has consistently found that:

 

• Properties rated C or above achieve higher sale prices and shorter marketing times than equivalent properties rated D or below
• The gap between C and D rated properties has widened as energy costs rose
• Buyers and mortgage lenders are increasingly factoring energy costs into affordability assessments

 

Some green mortgage products offer preferential rates for A or B rated properties, providing an additional financial incentive to improve EPC ratings before a sale.

 

Looking Up an EPC

All current EPCs for domestic properties in England, Wales, and Northern Ireland are publicly available on the EPC Register (epcregister.com). You can search by postcode to find:

 

• The current EPC rating and certificate for any property
• The date of the last assessment
• The recommended improvements and their potential impact
• Whether the property has had previous assessments

 

Scotland has a separate register, managed by the Scottish EPC Register (scottishepcregister.org.uk).

 

EPC and the Green Homes Grant / Funding Schemes

Many government energy efficiency grant schemes use EPC ratings as an eligibility criterion. Properties with lower EPC ratings (D and below) are typically prioritised for funding through schemes including:

 

• ECO4: requires a property to be EPC D or below (or E, F, G) to qualify for most measures
• Great British Insulation Scheme (GBIS): targets D or below rated properties
• Boiler Upgrade Scheme: focused on heat pump installation regardless of EPC rating

 

Improving your EPC rating before it reaches the threshold for a grant scheme could inadvertently disqualify you from funding. If you are planning improvements, speak to an installer about which measures to prioritise to maximise grant eligibility first.

 

EPC Data and What It Tells Us

The EPC register holds data on tens of millions of properties, creating a uniquely valuable dataset on the housing stock’s energy performance. EPC data analysis reveals:

 

• The geographical distribution of fuel poor households
• Which property types and construction eras have the worst performance
• The rate of improvement across the UK housing stock over time
• Where investment in energy efficiency would deliver the greatest impact

 

This data is used by policymakers, researchers, energy suppliers, local authorities, and investors to target programmes and understand the challenge of decarbonising UK housing.

 

Frequently Asked Questions

How long is an EPC valid? 10 years from the date of issue.

 

Can I use an old EPC when selling or letting? Yes, if it was issued within the last 10 years and lodged on the national register. However, if significant improvements have been made since the last assessment, a new EPC will reflect these changes and should be commissioned.

 

Does an EPC guarantee the stated energy costs? No. EPC energy cost estimates are modelled on standard occupancy assumptions. Actual costs depend on how the property is used, the number of occupants, and energy tariffs. The EPC is best used as a comparative measure rather than a precise prediction of bills.

 

Who can produce an EPC? Only a Domestic Energy Assessor accredited by an approved accreditation scheme. Self assessment is not permitted.

 

Can I challenge an EPC? Yes. If you believe an EPC is inaccurate, for example, if the assessor has incorrectly noted wall construction or heating type, you can raise a complaint with the accreditation body. Significant errors can result in a corrected certificate being lodged.

 

Does every room need to be assessed? The assessor assesses the whole dwelling, not individual rooms. They need access to all habitable areas, the loft, and the boiler or heating system.

 

Is an EPC the same as a home survey? No. An EPC assesses only energy efficiency. A home survey (Level 2 HomeBuyer Report or Level 3 Building Survey) assesses the structural condition, defects, and risks of the property. The two are produced by different professionals under different accreditation regimes.

If you’re selling, renting, or building a property in the UK, one of the small but essential costs you’ll come across is the Energy Performance Certificate (EPC). Prices usually fall between £40 and £120, which makes it much cheaper than most of the other legal checks involved in moving. The exact fee isn’t fixed; it varies depending on your property’s size, layout, and location, as well as the assessor you choose. 

Understanding how EPC pricing works can help you avoid overpaying and make sure you stay compliant with the law.

What is an EPC Certificate?

An EPC Certificate is a legally required document that shows how energy-efficient a property is. Commonly used in the UK and across Europe, you’ll encounter EPCs whenever a property is sold, rented, or built.

An EPC includes:

• Energy efficiency rating: From A (most efficient) to G (least efficient).
• Environmental impact rating: An estimate of the property’s carbon dioxide (CO2) emissions.
• Estimated energy costs: Covering heating, hot water, and lighting.
• Recommendations: Practical suggestions for improvements, such as better insulation, double glazing, installing a more efficient boiler, or adding solar panels.
  

Why do you need an EPC Certificate?

You need an EPC because it’s required by law. It helps potential buyers, tenants, and developers compare energy efficiency and running costs between properties. For homeowners, a good EPC rating can even make your home more attractive to buyers. A 2023 Rightmove survey found that 14.5% of home movers considered EPC ratings a major factor when choosing a property.

Who needs an EPC?

• Homeowners: Selling a property requires a valid EPC.
• Landlords and Property Investors: EPCs are mandatory when renting out homes, and the property must meet minimum energy efficiency standards (E or above) in most cases. Many landlords seek bulk EPCs for multiple properties.
• Estate Agents: Often arrange EPCs quickly on behalf of clients, although it may be more expensive than sourcing one directly from an accredited assessor.
• Tenants and Buyers: Use EPCs to estimate running costs before committing.
• Property Developers & Builders: EPCs are required for all new builds and conversions. This often involves SAP (Standard Assessment Procedure) assessments.
• Commercial Property Owners / Businesses: Need Commercial EPCs (CEPCs) to sell or lease offices, shops, warehouses, and other non-residential buildings.
• Public Sector Bodies: Schools, hospitals, and councils often require EPCs for compliance and access to funding.
  

There are exemptions, such as for some listed buildings, temporary properties (under two years of use), and certain places of worship.

How much does an EPC Certificate cost in 2026?

The price depends on property size, type, and whether it’s residential or commercial.

Average EPC costs for houses

The EPC certificate cost for most houses in the UK falls into the £45–£120 range. Smaller terraced homes or bungalows are cheaper to assess, while large detached homes with multiple bedrooms and extensions cost more.

EPC certificate costs for flats and rental properties

Flats are generally cheaper to obtain an EPC certificate, often £35–£75, because they’re smaller and sometimes share heating systems. Landlords managing several flats can usually negotiate better prices by ordering EPCs in bulk.

EPC certificate costs for commercial properties

Commercial EPCs are more expensive, but vary greatly. Prices can start as low as £100 for small offices, but can rise well over £1,000 for larger commercial buildings such as warehouses, schools, or office blocks. This reflects the additional time and complexity involved, and the buildings’ layout, usage, and location.

What factors affect EPC Certificate prices?

While you can expect standard ranges, the exact cost of your EPC depends on a few factors, including the assessor’s experience. Here are some other influences on EPC certificate costs.

Size and type of property

A larger property with more rooms and complex heating systems requires a more detailed survey. Detached homes cost more than mid-terraced ones for this reason.

Location and region

Prices vary across the UK. In London and the South East, assessors often charge more than in rural areas or the North due to higher demand and travel costs.

Residential vs. Commercial EPCs

Residential EPCs are straightforward and relatively affordable. By contrast, CEPCs take longer and require more detailed reporting, which explains their higher price. Unless you are buying, letting, or renting a CEPC, you don’t need to worry about this. 

How to get an EPC Certificate

The process is simple if you know where to look, and we can help you get your EPC Certificate without any hassle. 

Finding an accredited assessor

Only an accredited assessor can issue a valid EPC. You can search the official EPC register to find local assessors, or go through an estate agent. However, going directly to an assessor is usually cheaper.

How long does it take?

For a typical house, the inspection takes 30–60 minutes, and the certificate is usually available within 2–3 days. Larger or commercial buildings may take longer.

How long is an EPC valid?

An EPC is valid for 10 years. You’ll need to renew it if you’re selling or renting again after it expires. Some property owners also choose to update their EPC sooner if they’ve made major energy upgrades, for instance by installing wall insulations, floor insulations, or eco insulations. 

Tips for saving money on your EPC

While an EPC isn’t a huge expense compared to other property costs, there are still ways to save.

Bundling with other property services

Estate agents, surveyors, or letting agents sometimes offer EPCs as part of a sales or lettings package. This can be convenient, but it’s not always the cheapest option. It’s worth comparing against independent assessors.

Choosing a local assessor

Local assessors often charge less than national providers. They’re also more flexible on scheduling and turnaround. The best way to find someone nearby is by using our search tool.

Do I need an EPC Certificate?

An EPC certificate is a legal requirement in the UK and across the EU. For most homes, you’ll pay between £35 and £120, while commercial properties cost more. Failure to have a valid EPC when selling or renting could result in a fine – typically £200 for dwellings.

Whether you’re a homeowner preparing to sell, a landlord managing rentals, or a business owner leasing commercial space, making sure you’ve got a valid EPC is essential. By choosing a local accredited assessor and shopping around, you can get it sorted quickly whilst keeping your EPC certificate cost low. 

Don’t risk a fine or delays to your sale

An EPC is valid for 10 years and takes less than an hour to arrange. Book your EPC now and stay compliant with UK regulations.

Here at EPCcertificates we aim to explain what an EPC contractor does and how energy performance contracting helps improve EPC ratings. Energy Performance Contracting is becoming an increasingly popular way for homeowners, landlords, businesses and public bodies to reduce energy costs while improving EPC ratings. If you want to understand how an EPC contractor can help you make your property more energy efficient, it is useful to know what their role involves and how the contracting process works from start to finish.

What is Energy Performance Contracting?

Energy Performance Contracting is a structured service model in which an EPC contractor assesses a property and delivers energy-saving measures that improve the building’s overall performance. The contractor evaluates your current energy efficiency, recommends the right upgrades, installs those improvements and may even offer guarantees on the expected results. This approach is used widely across England, Wales and Northern Ireland because it gives property owners confidence that the improvements will deliver measurable benefits.

What an EPC Contractor does

An EPC contractor examines the condition of your home or commercial building and identifies ways to improve efficiency. Their role fills the gap between EPC assessors, who produce the Energy Performance Certificate EPC, and the specialist installers who carry out work such as insulation, heating upgrades or renewable technology installation. By working with an EPC contractor, you receive a clear plan based on evidence rather than guesswork. This ensures that the most effective measures are prioritised and installed safely.

How EPCs work in the UK

An EPC certificate rates a property from A to G. It outlines energy efficiency levels, environmental impact and estimated energy costs for heating, hot water and lighting. It also provides tailored recommendations that highlight how to make your home more energy efficient, such as installing insulation, replacing older boilers, upgrading windows or adopting low-carbon systems like heat pumps or solar panels. 

For buyers, tenants and estate agents, EPCs are essential because they give a reliable picture of a building’s expected running costs.

When you need an EPC

You are legally required to have an EPC when selling or renting out a property. This applies to homes across England, Wales and Northern Ireland, as well as commercial buildings that are being sold or let. New builds must also have EPCs and SAP assessments before they are completed. Some buildings are exempt, including certain listed buildings, places of worship and temporary structures. An EPC is valid for 10 years, and normally costs between £40 and £120, depending on the size and age of the property.

Why an EPC Contractor matters for improving ratings

An EPC contractor plays a key role in improving your EPC rating by translating the recommendations on your certificate into a practical plan. They help you prioritise which improvements will deliver the biggest uplift in rating and which upgrades will reduce energy bills most effectively. This is especially important for landlords, who must maintain a minimum EPC rating of E before renting a property. 

With regulations expected to tighten over the coming years, many landlords and developers are already planning ahead by working with EPC contractors to future-proof their buildings.

Typical measures delivered through Energy Performance Contracting

Energy Performance Contracting often focuses on upgrades that improve long-term performance. These include insulation, ventilation upgrades, air tightness improvements, efficient heating systems, hot water controls, LED lighting, double glazing and low carbon systems. 

Insulation is particularly impactful because much of the heat lost from a property escapes through the roof, walls and floors. Tackling these areas early usually offers the biggest improvement to an energy efficiency rating.

Who uses EPC Contractors?

A wide range of people and organisations use EPC contractors. Homeowners preparing to sell often want a better rating to attract potential buyers. Landlords and property investors rely on contractors to ensure compliance with rental regulations and to reduce tenant energy costs. Estate agents benefit from contractors who can deliver reliable upgrades quickly. Businesses and commercial property owners want to lower running costs and comply with energy legislation. Public buildings such as schools, hospitals and local authority offices also use EPC contractors to improve efficiency and meet sustainability commitments.

Benefits of Energy Performance Contracting

The main benefit of Energy Performance Contracting is the reassurance that improvements will deliver measurable results. You do not need to manage multiple installers or oversee complex projects yourself. Instead, the contractor guides you through the process, coordinates the work and ensures everything meets legal and industry standards. You benefit from lower energy bills, improved comfort and a better EPC rating, which can increase property value and appeal.

Common misunderstandings about EPCs and Contractors

A common misconception is that the EPC itself improves a property. In reality, the EPC only describes the current condition. You need to implement the recommended improvements to see real benefits. Another misunderstanding is that replacing a boiler alone is enough to significantly raise an EPC rating. 

Without effective insulation, much of the heat produced will still be wasted. An EPC contractor ensures improvements are carried out in the correct order so you get the best possible outcome.

How to choose the right EPC Contractor

Choosing the right contractor is important. Look for experience, relevant qualifications and a strong understanding of UK EPC regulations. A good EPC contractor will explain your options clearly and help you understand the impact of each improvement. They will also work with accredited installers who can complete the work safely and to a high standard, protecting your investment and ensuring compliance with building regulations.

The link between an EPC Contractor and insulation installer

Insulation is one of the most effective ways to improve an EPC rating. Whether you choose loft insulation, cavity wall insulation or external wall insulation, reducing heat loss has a direct and positive impact on energy performance. EPC contractors regularly collaborate with insulation specialists because these improvements often provide the most significant rating increase in the shortest time.

What is a commercial EPC?

A commercial EPC is an official document that rates the energy efficiency of a non-domestic building on a scale from A (most efficient) to G (least efficient). This Energy Performance Certificate (EPC) is a legal requirement for any property in England, Wales, or Northern Ireland that is being sold, rented, or newly constructed. It gives business owners, tenants, and buyers clear information about energy use, carbon emissions, and recommended improvements. These insights help reduce running costs and support better environmental performance across the commercial property market.

Commercial EPCs are carried out by accredited assessors who use specialist software and site inspections to calculate a property’s energy performance. The assessment is based on how the building is constructed and how energy systems are installed. It does not take into account how the current occupiers choose to use the building.

When do you need a commercial EPC?

You need a commercial EPC whenever a non-domestic property is being marketed for sale or rent, or when a new building is completed. This applies to shops, offices, warehouses, restaurants, factories, schools, hospitals, and mixed-use developments. From April 2025, landlords must have a valid EPC in place for any property that is let, and expired certificates must be renewed even if no lease activity is taking place. 

There are some exemptions. Listed buildings may be exempt if insulation or other energy upgrades would damage their architectural character. Places of worship and certain temporary structures can also be excluded. However, the majority of commercial buildings in the UK require a current certificate.

What does a commercial EPC show?

A commercial EPC displays the current energy efficiency rating of your building, estimated annual energy costs, and associated carbon dioxide emissions. It also includes:

• An asset rating based on the building fabric and mechanical services;
• A benchmark rating for similar building types;
• Suggested improvements and how they would increase your EPC rating; and
• Guidance on the payback period for each recommendation.

These recommendations are tailored to the property. For example, a warehouse may benefit most from improving lighting efficiency, while an office block might see the biggest gains from heat pump upgrades or external wall insulation. The aim is to help building owners target cost-effective investments.

How long does a commercial EPC last?

A commercial EPC is valid for 10 years. You can reuse the same certificate during this period unless major structural changes or refurbishments significantly affect the building’s energy performance. If your EPC expires while the property is being marketed or tenanted, you must arrange a new assessment to remain compliant. Because regulations are tightening, many landlords choose to update older EPCs early to reflect any improvements they have already made.

What are the legal requirements for landlords and property owners?

It is a legal requirement to hold a valid commercial EPC before selling or renting a non-domestic property. Local authorities can issue fines ranging from £5,000 to £150,000 for non-compliance, depending on rateable value. 

Under the Minimum Energy Efficiency Standards (MEES), most rented commercial buildings are required to achieve an EPC rating of E or above. The UK Government has announced plans for:

• Minimum EPC rating C for all new leases from 2027.
• Minimum EPC rating B for all leased commercial properties by 2030.

These changes will affect the majority of older properties, particularly those with ageing heating systems or insufficient insulation. Planning upgrades now can help minimise disruption and protect future income streams.

How much does a commercial EPC cost?

The cost of a commercial EPC depends on the size, complexity, and intended use of the building. Prices typically start from around £150 for small retail units and rise for large premises such as shopping centres or office complexes. Factors such as multiple heating zones, mezzanine floors, or on-site renewable energy systems can increase assessment costs. 

Why commercial EPC ratings matter

Commercial EPC ratings are becoming a critical part of property management and investment. They influence:

• Attractiveness to tenants and buyers;
• Operational energy bills and carbon reduction goals;
• Asset value and long-term return on investment;
  Planning for future regulatory changes; and
• Eligibility for grants and green financing.

In a competitive market like the UK, many organisations now use EPC ratings as part of their corporate sustainability credentials. A stronger rating shows a commitment to energy saving and reduces exposure to rising energy costs.

Who benefits from a commercial EPC?

A commercial EPC benefits everyone involved in owning, operating, or occupying a building. Key groups include:

• Business owners aiming to reduce running costs;
• Landlords improving property value and compliance;
• Estate agents and surveyors supporting marketing activities;
• Developers and builders delivering regulatory standards;
• Tenants seeking predictable and efficient premises; and
• Public authorities upgrading local infrastructure.

Clear and accessible energy data enables smarter decision-making at every stage of a property’s life cycle.

Can you improve your rating?

Yes, a commercial EPC rating can be improved by installing energy efficiency upgrades. Popular upgrades include:

• Wall and roof insulation;
• New energy-efficient HVAC systems;
• Heating controls and building automation;
• LED lighting upgrades; and
• Solar panels and other renewable technologies.

These measures reduce energy consumption and create more comfortable indoor environments. Many improvements offer strong payback times, especially in buildings with high heating or lighting demands.

Stay compliant and improve your property value

A commercial EPC is more than a legal requirement. It is an essential part of managing energy performance and protecting the long-term value of your property portfolio. Improving your EPC rating can lower energy bills, reduce emissions, and future-proof your building against upcoming regulatory changes. 

What is an EPC certificate in London?

An EPC certificate in London is an official document that rates the energy efficiency of a property on a scale from A to G. The certificate shows the current energy efficiency rating and also provides guidance on how to reduce energy costs and make the property more energy efficient. 

You must have a valid Energy Performance Certificate EPC before any home or commercial building can be sold or rented. For homeowners preparing to sell, it can influence interest from potential buyers. For landlords, it is a legal requirement that supports safer and more affordable living for tenants across the city.

An Energy Performance Certificate London assessment must be carried out by an accredited assessor who visits the property to collect information. This includes details about the building’s construction, heating systems, insulation levels, and windows. The better the design and upgrades, the stronger the EPC rating is likely to be.

What does an EPC certificate include?

Every EPC certificate includes the current energy efficiency rating, the environmental impact rating and estimated annual running costs for heating, lighting, and hot water. You will also receive recommended measures that can improve the rating, such as insulation, heating upgrades or improved glazing. EPC assessors will review elements such as your loft insulation thickness, whether the walls are solid or cavity, the age of the boiler, and whether you have low-energy lighting fitted.

These insights help tenants and buyers judge the affordability of living in the property before committing. For landlords, the EPC certificate London report provides a clear upgrade plan to meet future legal standards. For estate agents, having a strong EPC ready helps speed up the marketing process for clients.

When do you need an EPC certificate in London?

You are legally required to obtain an EPC certificate every time a property is sold or rented in London. This applies to houses, flats, HMOs, commercial units and public buildings. Landlords must provide an EPC certificate to tenants before a tenancy agreement begins. Estate agents will usually ask for it up front so the listing can go live without delays. Property developers and builders must also ensure EPCs are completed for new build compliance.

A small number of properties, such as certain listed buildings, may qualify for exemption if improvements would negatively impact protected features. However, most properties in England will always need an EPC certificate London when marketed for selling or renting.

How long does an EPC certificate last?

An EPC certificate in London remains valid for ten years. If a property undergoes major renovations that affect its energy efficiency, this may require a new EPC. it could be beneficial to receive a new EPC certificate London if you have paid for improvements that improve its rating. 

You should always ensure your EPC is up to date to avoid fines or problems with property transactions.

EPC rules for landlords in London

Landlords in London must currently ensure their rental properties achieve a minimum EPC rating of E. This rule applies to houses, flats, HMOs and commercial properties across the city. If a property is rated F or G, landlords must make improvements before new tenants can move in. Fines for non-compliance can reach thousands of pounds.

The government is likely to review energy efficiency standards in the near future and may introduce stricter rules to reduce energy bills for tenants and help London move towards national energy saving and climate goals. Acting early is better than waiting until demand pushes costs up, especially for landlords with multiple properties.

What does an EPC cost in London?

The price of an EPC certificate London assessment is usually between £50 and £150 (including VAT) for residential homes, but it depends on the property’s size and complexity. Larger or older properties may take longer to assess and therefore cost slightly more. Commercial EPCs are more specialist and typically higher in cost due to the detailed analysis required.

Booking directly with a qualified assessor can help keep costs down and secure quicker appointments. For landlords or investors who need several EPCs at once, bulk booking discounts are often available.

Can EPC ratings be improved?

EPC ratings can be improved by upgrading energy efficiency features in a property. Popular methods include:

• Adding loft insulation or upgrading existing insulation.
• Installing cavity wall or solid wall insulation.
• Switching to energy-efficient windows and doors.
• Replacing an old boiler with a modern, efficient heating system.
• Installing smart heating controls and LED lighting.

These upgrades not only improve EPC certificate London ratings but also reduce energy bills. Tenants increasingly prioritise properties with better EPC ratings as they can be cheaper to run and more comfortable year-round.

How to find an EPC certificate in London

To search, download or verify a certificate, you can use our EPC checker for England, Wales or Northern Ireland. You only need the property address or postcode to locate the document. This service is widely used by landlords, letting agents, buyers and tenants who want to check a property’s energy efficiency rating and its recommended improvements.

Why EPCs matter in London

EPC certificates matter in London because they promote better quality housing, support legal compliance and help reduce environmental impact. In such a competitive market, a strong EPC rating can make a property more attractive and may even increase the asking price or rental income.

With rising energy costs, more buyers and tenants are checking EPC ratings before making decisions. Lenders and public funding providers increasingly consider EPC ratings when offering mortgages or improvement grants. Better ratings, therefore, add real value to London properties while helping the city move towards cleaner and more energy-efficient housing.

Take your next step: improve your rating and save money

If you want to improve your EPC certificate London score or simply cut your heating bills, insulation upgrades are a smart place to start. Enhanced insulation makes a property warmer, greener and more affordable to run. To explore your insulation options and find local trusted installers, visit EcoInsulation.co.uk today.

A more energy-efficient home benefits you now and increases the future value of your property. Start making improvements that save energy and support a better EPC rating for years to come.

The UK has some of the highest energy bills in Europe, making the EPC rating of a property more important than ever. Whether you’re a homeowner looking to sell, a landlord managing rentals, or a tenant comparing running costs, the A–G scale can have a major impact. 

But what does an EPC rating really mean, and why should you care?

In this guide, we’ll break it down so you have everything you need to know about EPC ratings, how they’re calculated, and what you can do to improve yours.

What is an EPC rating?

An EPC rating is the score given to a property on its Energy Performance Certificate (EPC). It places the property on a scale from A (most energy efficient) to G (least efficient). Along with the letter rating, the EPC includes important details such as:

• Typical energy costs for heating, hot water and lighting.
• An energy efficiency rating that you can compare with other homes or buildings.
• Suggested energy-saving improvements to help reduce bills and carbon emissions.

The intention is simple: an EPC rating gives potential buyers or tenants a quick and easy way to see how efficient a property actually is.

If you live in England, Wales or Northern Ireland, EPCs are part of the legal process for most buildings that are being sold or rented. Scotland has a separate EPC register, but the principles are the same.

Why are EPC ratings important?

Legal requirements

It’s the law. You must have a valid EPC whenever a property is sold, rented, or built. This applies to both homes and commercial premises, including public buildings.

There are some exemptions, such as for certain listed buildings where improvements would alter historic character, or temporary structures. Failure to comply typically means fines (around £200 for homes, rising to £5,000 for commercial or larger properties).

Impact on sales and rentals

Your EPC rating can affect how easily your property sells or rents. In today’s housing market, many buyers and renters are looking for energy-efficient homes because they cost less to run. Research by Rightmove suggests that nearly 15% of home movers see EPC ratings as a major deciding factor.

For landlords, the Minimum Energy Efficiency Standards (MEES) mean you cannot legally let a property with an EPC rating lower than E, unless you have an exemption.

In other words, your EPC rating isn’t just paperwork. It’s directly linked to compliance, marketability, and profitability.

How is an EPC rating calculated?

When an accredited EPC assessor visits your property, they look at a wide range of building features, including:

• Insulation: loft, cavity wall, roof, and floor insulation levels.
• Heating systems: the efficiency of boilers, whether you have smart controls, or if you use newer technology like heat pumps.
• Lighting: the type of lighting and how energy-efficient your bulbs are.
• Glazing and doors: single, double, or triple-glazed windows, and draught-proofing.
• Renewable systems: solar panels, wind turbines, or energy-saving tech like solar thermal.

All this information feeds into the calculation that produces your final EPC rating on the A–G scale. You can search for any address with our tool and find out the property’s grade.

The A–G scale explained

• EPC rating A: Excellent efficiency. Very low predicted energy costs, often found in new builds with renewable energy systems or heavily retrofitted homes.
• EPC rating B: Still highly efficient. Modern insulation, double-glazing, and efficient heating contribute to this band.
• EPC rating C: Better than average, increasingly the standard target for homes. Often considered a ‘sweet spot’ for attracting buyers.
• EPC rating D: The current UK average. Not bad, but with plenty of room to improve efficiency.
• EPC rating E: The legal minimum for renting in England, Wales or Northern Ireland. Not efficient, and likely to come with higher energy bills.
• EPC rating F: Below rental standards. Outdated insulation or heating leads to high costs and wasted energy.
• EPC rating G: The lowest possible score. Very high energy costs and poor comfort; extensive improvements are usually required.

Each band not only reflects efficiency but also carbon emissions and running costs, making it a useful snapshot of your property’s environmental impact.

How to improve your EPC rating

Improving your EPC rating doesn’t just tick compliance boxes – it makes your property more pleasant to live in and cheaper to run.

Practical steps to boost EPC ratings

• Insulation upgrades: Loft, external wall, cavity wall, or floor insulation is often the most effective improvement. 
• New windows: Replacing single glazing with double or triple glazing.
• Efficient heating systems: Replacing an old boiler, fitting smart controls, or installing a heat pump.
• Lighting: Switching all bulbs to LEDs.
• Renewables: Adding solar PV or solar thermal panels to reduce dependence on traditional fuels.

Grants and schemes

Across the UK, there are government schemes and energy supplier initiatives to help cover the cost of improvements. These could include insulation grants, heat pump incentives, or support for low-income households. Checking what’s available can make upgrading more affordable while boosting your EPC rating.

Who needs an EPC and when?

• Homeowners: You must provide an EPC when selling your home. Even if you’re not moving, improving your EPC rating can make your house more energy efficient and comfortable.
• Landlords: Rental properties must achieve at least an EPC rating of E unless exempt. EPCs are legally required every time a new tenancy starts.
• Estate agents & buyers: EPCs help potential buyers decide quickly on how costly a home will be to run. Buyers may ask their estate agent to obtain an EPC certificate on their behalf.
• Commercial properties: Offices, warehouses, shops, and public buildings also need EPCs, known as Commercial EPCs (CEPCs). For larger public buildings, a separate Display Energy Certificate (DEC) may be needed.
• Developers & builders: Every newly built property must have an EPC before being sold or rented.

How to get an EPC certificate

Booking an assessor

Only an accredited assessor can issue a valid EPC. You can find one local to you using our trusted search, and you should be able to schedule a time within a few days.

Costs and validity

• For homes, EPC costs typically fall between £40 and £120, depending on size and location.
• For businesses, commercial EPCs start around £150 but can rise to several thousand for large or complex sites.
• Once issued, your EPC remains valid for 10 years, unless you make major changes to the property that would affect its rating.

EPC ratings and future regulations

The UK’s long-term commitment is to reach net-zero carbon emissions by 2050. Housing and buildings play a massive role in achieving this.

• Minimum standards: At present, landlords must achieve an EPC rating of E or above, but future regulations may raise this to C, especially for rental properties.
• Public buildings: Expect continued focus on making public sector estates more energy efficient, with stricter disclosure through EPCs and DECs.
• Property investors and developers: Staying ahead of regulations will protect long-term asset value.

Common misconceptions about EPC ratings

EPC vs energy bills

An EPC shows the predicted energy efficiency rating, but real-life bills still depend on habits and other factors. For example, leaving heating on all day will lead to higher bills, even if your EPC rating is strong.

EPCs are only for selling or renting

Not true. While an EPC is legally required when a property is sold or rented, you can commission one anytime for your own benefit. It gives you a clear idea of where to focus on energy-saving upgrades to reduce future bills.

EPCs are always perfectly accurate

EPCs are based on standard assumptions, so they don’t reflect every household’s lifestyle. But they do provide a consistent benchmark for comparison, which is why they’re legally required across the UK.

Final thoughts

Your EPC rating is more than a letter on a certificate. It affects how quickly your property sells, whether you can legally rent it out, and how much you’ll spend on energy. From listed buildings with unique challenges to modern new homes designed to be highly energy efficient, every property benefits from understanding its EPC rating.

For anyone in England, Wales, Northern Ireland, or Scotland, the process is straightforward: book an accredited assessor, receive your Energy Performance Certificate EPC, and use the recommendations to make your property more efficient.

Even small improvements, like insulation or LED lighting, can make a noticeable difference to your EPC rating, comfort, and energy bills. With regulations tightening and buyers caring more about efficiency, now is the perfect time to review your property’s EPC rating and take action.

1. What is an EPC rating D?

An EPC rating D means your property falls in the middle of the UK’s Energy Performance Certificate (EPC) scale, which ranges from A (most efficient) to G (least efficient). Most UK homes currently sit in band D, so it’s a very common rating. It indicates that your property is reasonably efficient but has considerable scope for improvement in areas such as insulation, heating systems, and renewable energy technologies.

2. How EPC ratings are calculated

EPC ratings are calculated using the Standard Assessment Procedure (SAP). An official assessor will need to look at how much energy your home uses and how much it costs to heat, light, and provide hot water. They will also factor in building materials, insulation levels, window glazing, and heating systems. The result is both an energy efficiency rating (the EPC band) and an environmental impact rating, which shows your property’s CO2 emissions.

3. Why is an EPC rating D significant?

An EPC rating D matters because it highlights that your home performs at an average level for energy efficiency. While your property isn’t failing, it also doesn’t perform as well as properties in bands A–C, and you could likely improve it. For homeowners, an EPC rating D means you’ll face higher energy costs; for landlords, you could face challenges with compliance as regulations tighten; and for buyers, this rating signals that you may need upgrades.

4. Is EPC rating D good or bad?

A property with an EPC rating D isn’t bad, but people don’t consider it good either. It occupies a middle ground: acceptable today, but people increasingly view it as below standard as the UK pushes towards net-zero targets. With rising bills and the ongoing cost-of-living crisis, buyers and tenants are becoming more conscious of energy efficiency ratings, so a property in band D may be less attractive than one in band C or above.

5. EPC rating D and UK property regulations

Currently, in England, Wales and Northern Ireland, rental properties must achieve at least an EPC rating E to be legally let. However, the government has proposed raising this minimum to band C by 2030 for most rented homes. 

If you’re a landlord with a property in band D, you’ll likely need to invest in upgrades in the coming years to remain compliant.

6. Impact of an EPC rating D on energy bills

A property with an EPC rating D typically has higher energy costs compared to a C or B-rated home. For example, improving from band D to C can save hundreds of pounds per year, depending on property size. With rising energy prices, the difference between EPC bands can have a real impact on household budgets and long-term affordability.

7. EPC rating D and property value

EPC ratings increasingly influence property value. A home in band D may sell for less than a similar home in band C or above because potential buyers are factoring in the cost of future upgrades and higher energy bills. Estate agents report that homes with higher EPC ratings often sell faster and attract more interest, making efficiency an important selling point.

8. Can you rent a property with an EPC rating D?

Yes, you can currently rent a property with an EPC rating D, as it is above the legal minimum band E. However, landlords should be aware of the proposed changes that could make band C the new standard. Future-proofing your property by improving its rating now can help avoid disruption and costs later.

9. How to improve a home from EPC D to C

The quickest way to improve from band D to C is by tackling insulation and heating efficiency.

• Quick wins: Switch to LED lighting, draught-proof windows and doors, and install smart heating controls.
• Bigger upgrades: Add cavity or solid wall insulation, upgrade loft insulation, fit double or triple glazing, and replace an old boiler with a modern condensing boiler or heat pump.

10. Grants and financial support for EPC upgrades

If your property has an EPC rating D, you may be eligible for government or local authority support to make improvements. Schemes such as the ECO4 programme and the Great British Insulation Scheme provide funding for insulation and heating upgrades. Homeowners in certain council tax bands, or those receiving benefits, may qualify for free or subsidised improvements.

11. Future of EPC standards in the UK

The UK is tightening EPC requirements as part of its net-zero strategy. While rating D is currently common, the government’s long-term ambition is for most homes to achieve band C or better by 2035. This means that properties in band D will become less acceptable over time, making it more important to act now.

12. What an EPC rating D means for homeowners and landlords

For homeowners, an EPC rating D means higher energy bills, lower comfort, and potentially reduced property value. In the case of landlords, it means a looming deadline to upgrade before new regulations take effect. Buyers should take it as a warning sign that future investment may be required.

The good news is that improving from EPC D to C is achievable with the right measures. Moreover, grants are available to help.
