How Much Does an EPC Cost in 2026?

An Energy Performance Certificate is one of the first things you need to organise when preparing to sell your home. It is a legal requirement, and you cannot market your property without one. Yet many sellers are unsure what an EPC costs, what affects the price, or how to find a reliable assessor.

This guide explains the current cost of an EPC in England and Wales, what you get for your money, how to find a qualified Domestic Energy Assessor, and how the EPC fits into the broader costs of selling. For a detailed explanation of what the certificate itself covers, see our guide on EPC certificates explained.

Current EPC costs in 2026

The cost of an EPC for a standard residential property in England and Wales ranges from £60 to £120. The majority of homeowners pay between £70 and £90 for a typical two- or three-bedroom house. There is no fixed or government-set price — assessors set their own fees, so costs vary depending on your property and location.

Typical EPC costs by property size

These figures are based on published pricing from accredited assessor networks including Quidos and Elmhurst Energy. Prices in London and the South East tend to be at the higher end of each range, while assessors in the Midlands, the North, and Wales are typically cheaper.

What affects the cost of an EPC

Several factors influence how much you pay for your EPC. Understanding these can help you get the best value:

• Property size. Larger properties take longer to assess and cost more. A one-bedroom flat might take 20 minutes, whereas a five-bedroom detached house could take over an hour.
• Property type and complexity. Unusual construction methods, extensions, mixed heating systems, or properties with multiple fuel types may take the assessor longer and increase the fee.
• Location. Assessors in areas with higher living costs or lower competition may charge more. Rural properties where the assessor has to travel further can also attract a premium.
• Assessor choice. Independent assessors who operate through online booking platforms often charge less than those who work exclusively through estate agent referrals. However, the quality of the assessment should be the same, as all DEAs use the same approved methodology.
• Bundled services. Some estate agents include the EPC in their marketing package, which can reduce the standalone cost. Others add a markup. Always check whether the price is competitive before accepting a bundled deal.

The EPC is one of several costs you face when selling. For a complete breakdown of every expense, see our guide on how much it costs to sell a house in 2026.

How long is an EPC valid?

An EPC is valid for 10 years from the date it was issued. If you purchased your property, remortgaged, or rented it out within the last decade, you may already have a valid certificate. You can check for free on the GOV.UK EPC register.

If a valid EPC exists, you can use it for your sale without paying for a new one — even if you have made changes to the property since the assessment. However, if you have carried out energy improvements such as adding insulation, replacing the boiler, or installing solar panels, a new EPC may give you a higher rating. A better rating can make your property more attractive to buyers and may support a stronger asking price.

When you need a new EPC

You need to commission a new EPC if:

• Your existing certificate has expired (more than 10 years old)
• You have never had an EPC for the property
• You have made significant energy improvements and want the higher rating reflected in your listing
• The SAP methodology has been updated since your last assessment (SAP 10.2, introduced in 2022, benefits electrically heated properties)

When you need an EPC for selling

Under the Energy Performance of Buildings (England and Wales) Regulations 2012, you must have a valid EPC before you market your property for sale. This means the certificate must be lodged on the official register before your estate agent creates the listing or you begin advertising privately.

Your estate agent is legally required to display the EPC rating in all property advertisements, including online listings on Rightmove and Zoopla. If you instruct an agent without having a valid EPC, neither you nor the agent can lawfully proceed with marketing.

The penalty for marketing a property without a valid EPC is a fine of up to £5,000, issued by your local authority's trading standards team. In practice, enforcement is most commonly directed at estate agents, but the legal obligation rests with the seller. The EPC is one of the essential documents needed to sell a house.

How to find a qualified Domestic Energy Assessor

An EPC can only be produced by a Domestic Energy Assessor (DEA) who is registered with a government-approved accreditation scheme. There are several ways to find one:

1. The EPC Register. The official EPC Register has a "Find an assessor" feature where you can search by postcode to find accredited DEAs in your area.
2. Accreditation body websites. The main accreditation schemes — Quidos, Elmhurst Energy, Stroma, and ECMK — each maintain directories of their registered assessors.
3. Your estate agent. Many agents have a preferred assessor or can arrange the EPC as part of their service. This is convenient but check the price is competitive.
4. Comparison platforms. Online platforms allow you to enter your postcode and property details to receive quotes from multiple assessors, making it easy to compare prices.

When choosing an assessor, verify that they are registered with one of the approved schemes. You can check their accreditation number on the relevant scheme's website. An unaccredited individual cannot produce a legally valid EPC.

What happens during an EPC assessment

The assessor visits your property and inspects the features that affect its energy performance. The visit typically takes 30 to 60 minutes, depending on the size and complexity of the property. Here is what they look at:

• Walls — whether they are cavity or solid, and whether they have been insulated
• Roof and loft — the type and depth of insulation (the recommended minimum is 270mm)
• Windows — single, double, or triple glazed, and the approximate age of the glazing
• Heating system — the boiler type, age, efficiency rating, and heating controls (thermostat, programmer, thermostatic radiator valves)
• Hot water — how hot water is provided and whether the tank is insulated
• Lighting — the proportion of low-energy (LED or CFL) light fittings
• Renewable energy — solar panels, heat pumps, or other on-site generation

The assessor enters the data into approved RdSAP (Reduced Data Standard Assessment Procedure) software, which calculates the energy efficiency rating and environmental impact rating. The certificate is then lodged on the EPC Register, usually within 24 to 48 hours.

How to prepare for the visit

You can help the assessment go smoothly and ensure an accurate result by having the following information available:

• The age of the property (or approximate decade of construction)
• Details of any loft or wall insulation you have added
• The boiler make, model, and installation date
• Certificates for any recent improvements (e.g. FENSA certificate for replacement windows, building regulations sign-off for a new boiler)
• Documentation for renewable energy installations (MCS certificate for solar panels or heat pumps)

Without evidence, the assessor may have to assume a lower specification, which could result in a worse rating than your property deserves.

EPC ratings explained

The EPC rates your property on a scale from A (most efficient) to G (least efficient), with a numerical score from 1 to 100. The average rating for homes in England and Wales is band D, with a score of around 62.

The rating matters more than ever. Buyers increasingly factor energy efficiency into their purchasing decisions, and a growing number of lenders offer preferential "green mortgage" rates for properties rated C or above.

Improving your EPC rating before selling

If your current rating is lower than you would like, there are cost-effective improvements that can move you up one or two bands. The EPC recommendations report lists specific measures for your property, but the most common high-impact changes are:

1. Top up loft insulation to 270mm. This is one of the cheapest measures, costing £300 to £600, and can add 5 to 10 points to your score.
2. Install cavity wall insulation. Suitable for most homes built between the 1920s and 1990s, costing £500 to £1,500, with a potential gain of 10 to 15 points.
3. Upgrade heating controls. Adding a room thermostat, programmer, and thermostatic radiator valves costs £150 to £400 and can add 3 to 8 points.
4. Replace all lighting with LEDs. At under £100 for most homes, this is one of the simplest improvements and adds 2 to 5 points.
5. Replace an old boiler. A modern condensing boiler costs £2,000 to £4,000 but can add 10 to 20 points. This is only worthwhile if the boiler already needs replacing.

After making improvements, you will need to commission a new EPC to reflect the changes. The cost of the new assessment (£60 to £120) is small compared to the potential benefit of a higher rating in your listing.

EPC exemptions

Certain properties are exempt from the EPC requirement. The exemptions are set out in the Energy Performance of Buildings Regulations:

• Listed buildings — exempt where compliance with energy performance requirements would unacceptably alter their character or appearance
• Places of worship — buildings used primarily for religious activities
• Temporary buildings — structures with a planned use of two years or less
• Stand-alone buildings under 50 square metres — provided they are not dwellings
• Buildings due for demolition — properties subject to a demolition order

The listed building exemption is not automatic. It applies only where the improvements needed to meet energy performance standards would unacceptably alter the building's character. Many listed buildings do have EPCs. If you believe your property qualifies for an exemption, confirm this with your solicitor before marketing without a certificate.

Upcoming changes to EPC requirements

The UK Government has signalled its intention to raise minimum EPC standards, and these changes could affect the value and urgency of your certificate:

• Minimum rating for rented properties. Current proposals would require all rented properties in England and Wales to achieve a minimum EPC rating of C by 2030. While this does not directly affect owner-occupier sales, it influences buyer expectations, particularly for buy-to-let investors who represent a significant portion of the market.
• New SAP methodology. The transition from SAP 10.2 to a future version of the Home Energy Model is expected to change how ratings are calculated, potentially benefiting properties with electric heating and heat pumps while adjusting gas boiler assessments.
• Mortgage market pressure. An increasing number of lenders are linking mortgage products to EPC ratings, offering better rates for properties rated C or above. This trend is likely to continue, making higher-rated properties more financially attractive to buyers.

Keeping your EPC rating as high as possible positions your property well regardless of how regulations evolve.

Scotland: the Home Report difference

If you are selling in Scotland, the system works differently. Rather than a standalone EPC, Scottish sellers must provide a Home Report, which bundles three documents together:

• An Energy Performance Certificate (the EPC itself)
• A property survey carried out by a qualified surveyor
• A property questionnaire completed by the seller

The cost of a Scottish Home Report is significantly higher than a standalone EPC, typically £500 to £1,000, because it includes the full property survey. In England and Wales, the buyer commissions and pays for their own survey, so the seller only needs the EPC itself.

Getting the best value from your EPC

To ensure you get good value and an accurate rating:

1. Check the EPC Register first. Search for your address on the GOV.UK EPC register to see if you already have a valid certificate. If one exists and the rating is acceptable, you do not need to pay for a new one.
2. Get two or three quotes. Assessor fees vary, so comparing prices can save you £20 to £40. Use the EPC Register's assessor search or an online comparison platform.
3. Prepare for the assessment. Have documentation ready for any improvements you have made (insulation certificates, FENSA window certificates, boiler installation records). Without evidence, the assessor must assume default values, which are often less favourable.
4. Make quick improvements first. Simple changes like switching to LED bulbs, adding loft insulation, or fitting a hot water tank jacket can improve your rating and cost very little.
5. Do not overpay through your agent. If your estate agent offers to arrange the EPC, check the price against independent assessor quotes. Some agents charge a convenience premium.
