Free EPC check by postcode
You can use your postcode to search for available EPC certificate records and select your address. If a valid EPC is available, the checker will show the current rating band, score and potential rating where provided.
How do I check the EPC of my house?
Enter your postcode, choose your address, and the checker will show EPC data where available. If your property does not appear, the certificate may be missing, expired, unavailable or recently updated.
What is a valid EPC?
An EPC is normally valid for a set period from the certificate date, but the rating may not reflect recent improvements. If you have upgraded your home, a new EPC assessment may be needed.
What is an EPC rating?
An Energy Performance Certificate (EPC) is a survey-based rating of how efficient a property is. It scores a home from A (most efficient) to G (least efficient) and shows both a current rating and a potential rating that could be reached with recommended improvements. EPCs are required when a property is built, sold or rented out, and they are valid for ten years.
What does each EPC band mean?
- A
Most efficient
New-build standard or major retrofit. Very low running costs.
- B
Highly efficient
Modern fabric and heating. Generally low running costs.
- C
Above average
Often the target after upgrades. Some grant routes still apply.
- D
Average
Typical for many older UK homes. Often a key target for grant funding.
- E
Below average
Likely to benefit from insulation and heating upgrades.
- F
Poor
Cold, expensive to run and a priority for support.
- G
Very poor
Highest priority for help. Larger grants may be available.
Why EPC D, E, F and G homes may be worth checking for grants
Most major UK energy grants prioritise homes with an EPC of D-G because they have the most to gain from upgrades. Households in lower-rated homes may qualify for ECO4, Warm Homes funding or local council schemes, especially if they receive qualifying benefits or meet local flexible eligibility criteria.
Read the guide to grants for D-G homesHow to improve your EPC rating
- Top up loft insulation to current standards (around 270mm).
- Add cavity wall, solid wall or under-floor insulation where suitable.
- Upgrade to modern heating controls and a high-efficiency boiler or heat pump.
- Switch all lighting to LEDs and improve draught-proofing.
- Consider solar PV and battery storage where roof orientation allows.
EPC ratings for landlords
Private landlords in England and Wales must hold a valid EPC before letting and the property must currently meet at least band E to comply with Minimum Energy Efficiency Standards. Tighter standards have been proposed for the rental market, so it is worth planning insulation and heating upgrades early. Some grant routes are open to landlords, often with a contribution.
What if your EPC is missing or out of date?
If you cannot find an EPC for your home, the survey may be more than ten years old or the certificate may not have been lodged. A new EPC is straightforward to commission from a domestic energy assessor and is often a useful starting point before applying for grants.

Does my EPC rating affect energy grants?
Yes. Many UK schemes such as ECO4 and Warm Homes funding prioritise homes rated D, E, F or G. A low EPC rating does not guarantee eligibility, but it is often a key factor that is worth checking alongside income, benefits and household circumstances.
What is an EPC rating?
An Energy Performance Certificate (EPC) rates a home from A (most efficient) to G (least efficient) based on a survey of its construction, heating and insulation. EPCs are required when a property is built, sold or let and are valid for ten years.
What does each EPC band mean?
Bands A and B indicate very efficient homes with low running costs. C is above average. D and E are common for older UK homes. F and G indicate poor energy performance and high running costs, and are usually prioritised for grant support.
Why may EPC D, E, F and G homes be worth checking for grants?
Schemes such as ECO4 and Warm Homes: Local Grant target homes with low EPC ratings because they have the most to gain. If your home is rated D-G, it is worth checking the grant checker and your council.
How can I improve my EPC rating?
Common improvements include topping up loft insulation, fitting cavity or solid wall insulation, upgrading heating controls or installing a heat pump, switching to LED lighting and adding solar PV. The right mix depends on your property.
What if my EPC is missing or out of date?
You can commission a new EPC from a domestic energy assessor. A new survey is also a useful step before applying for grants, as many schemes use the EPC to confirm eligibility.
Do landlords need an EPC?
Yes. Landlords in England and Wales must hold a valid EPC before letting and the property must meet the Minimum Energy Efficiency Standard (currently EPC E or above). Tighter standards have been proposed, so it is worth planning ahead.
