Do You Need an EPC to Sell a House? 2026 Rules

Is an EPC Legally Required to Sell a House?

Most sales require an EPC, which must be commissioned before marketing if a valid certificate is not already available. The seller and agent must make reasonable efforts to obtain it within seven days, with a further 21 days if those efforts fail. The certificate must be made available to prospective buyers as required (GOV.UK marketing guidance).

The requirement applies to almost every residential property in England and Wales. A small number of buildings are exempt, including listed buildings where compliance would unacceptably alter their character, temporary structures intended to be used for less than two years, and certain places of worship. If you are unsure whether an exemption applies, check with your local authority or conveyancer before assuming you can skip the certificate.

An EPC is generally valid for ten years from the date of issue, or until it is superseded by a newer assessment. If you already have a certificate that has not expired, you do not need to order a fresh one, though some sellers choose to if they have made improvements since the last assessment.

What Is an EPC and What Does It Show?

An EPC rates a property's energy efficiency from A to G. It is produced by an accredited domestic energy assessor who visits the property and records construction details, heating systems, insulation levels and other features.

The certificate includes two main elements. The first is the current energy efficiency rating. The second is a list of recommended improvements, each with an estimated impact on the rating. The rating does not predict your actual monthly energy bill because that depends on occupancy, fuel use and tariffs (GOV.UK, EPCs).

Buyers may use the rating and recommendations when comparing homes. A higher rating does not guarantee a higher sale price or a particular mortgage decision.

For a full explanation of each band, see our guide to EPC ratings explained.

How Much Does an EPC Assessment Cost?

There is no fixed government fee for an EPC. Prices vary by region, property size and assessor. As an illustrative budgeting example, assume a typical three-bedroom semi-detached house might cost roughly £60 to £120 for a domestic EPC assessment, though actual quotes may fall outside that range. Always obtain at least two quotes from accredited assessors.

Ask the assessor how long the visit will take for your property. The assessor inspects loft spaces, measures rooms, checks boiler details and photographs key features. Confirm the delivery timescale with the assessor and check the lodged certificate on the EPC register.

If your existing EPC is still valid and you have not made significant changes, there is no obligation to pay for a new one. If you have added insulation, replaced the boiler or installed a heat pump since the last assessment, a fresh EPC could reflect a better rating and help your sale.

More detail on assessment costs is available in our EPC certificate cost guide.

What Happens If You Sell Without an EPC?

Trading standards officers can issue a penalty notice for non-compliance. The penalty applies to the seller, not the buyer. Agents also have duties to check commissioning and make reasonable efforts to obtain the certificate within the required timescale.

The absence of an EPC does not invalidate a completed sale, but it can cause delays. Conveyancers routinely check the EPC register during the transaction, and a missing certificate can stall exchange of contracts.

Can You Improve a Low EPC Rating Before Selling?

Yes, and it is often worth doing. The EPC recommendations report lists measures in order of cost-effectiveness. Common upgrades that can shift a rating include loft insulation to the recommended 270 mm of mineral wool, cavity wall insulation, draught-proofing, upgrading an old boiler and fitting a hot-water cylinder jacket (Energy Saving Trust, Roof and loft insulation).

Do not assume a fixed number of EPC points for an improvement. The effect depends on the existing construction, heating and assessment inputs, and may not move the property into another band. Ask an assessor for a property-specific estimate before relying on a predicted rating.

Our guide on how to improve your EPC rating ranks common upgrades by typical cost and rating impact.

Which Grants Could Help Improve Your Rating?

Several government-backed schemes can fund energy improvements. None guarantee approval, and eligibility depends on your circumstances.

ECO4

The Energy Company Obligation (ECO4) runs until 31 December 2026. It funds insulation, heating upgrades and other measures for eligible households. Eligibility is not automatic: it depends on home tenure, EPC rating, household income or qualifying benefits, and the specific measures proposed. Your energy supplier or a council referral through ECO4 Flex can determine whether you qualify. ECO4 does not guarantee a free boiler or whole-house upgrade for every benefit claimant.

Warm Homes Local Grant

The Warm Homes Local Grant covers private homes in England rated EPC D to G. Household income is usually at most £36,000, though qualifying benefits or postcodes can provide alternative routes. A national application portal exists at GOV.UK, and councils deliver the scheme locally. Funding delivery runs to March 2028. Landlords may need to contribute. Available measures and funding depend on council surveys and remaining budget.

Boiler Upgrade Scheme

If you are considering replacing a fossil-fuel boiler with a heat pump before selling, the Boiler Upgrade Scheme (BUS) offers £7,500 towards an air-to-water or ground-source heat pump in England and Wales. Off-gas-grid homes replacing oil or LPG heating can receive £9,000 (available until March 2027). The property must be owned, the installer must be MCS-certified, and commissioning must happen within 120 days of applying. BUS funding is confirmed through fiscal year 2029/30. A heat pump installation can improve an EPC rating, though the exact impact varies by property.

Zero-rate VAT on energy-saving materials

Qualifying installed energy-saving materials, including insulation and heat pumps, carry zero VAT through 31 March 2027, after which the rate is scheduled to rise to 5%. This applies to professionally installed materials, not supply-only DIY purchases.

Timing Your EPC Around a Sale

Order your EPC early in the selling process. If the rating is lower than expected, you still have time to make improvements and commission a fresh assessment before marketing. A better rating can support a higher asking price and attract buyers who are concerned about future energy costs or upcoming landlord regulations.

If you are selling a rental property, be aware that the current Minimum Energy Efficiency Standard (MEES) in England and Wales requires EPC band E, with a £3,500 cost cap on required improvements and a maximum penalty of £5,000 for non-compliance. The government has proposed raising the standard to EPC C equivalent by 1 October 2030, with a new £10,000 cost cap, though this is future policy and not yet law. Buyers of investment properties will factor these rules into their offers. Our landlord EPC requirements guide covers the current and proposed rules in detail.
