EPC Checker: How to Find Your Home’s Energy Rating

An Energy Performance Certificate (EPC) rates how energy efficient your home is, from A (best) to G (worst). You can look yours up online in a couple of minutes. Your rating also decides whether you can get help with insulation and heating upgrades through a scheme like ECO4.

How to check your EPC rating

In England, Wales and Northern Ireland, use the GOV.UK "Find an energy certificate (opens in a new tab)" service. Search by postcode, by street name and town, or by certificate number.
In Scotland, properties are on a different register. Use the Scottish EPC Register (opens in a new tab) instead.
Find your address in the results and open the certificate. Your rating is shown as a letter from A to G.

What the EPC bands mean

Band	Points (SAP score)	In plain terms
A	92 or more	Most efficient. Rare in older homes.
B	81 to 91	Very efficient.
C	69 to 80	Good. Above the level grants are aimed at.
D	55 to 68	Room to improve. Can qualify for ECO4 if you own your home.
E	39 to 54	Poor. Can qualify for ECO4 whether you own or rent.
F	21 to 38	Very poor. Can qualify for ECO4.
G	1 to 20	Least efficient. Can qualify for ECO4.

Why your EPC rating matters for grants

Under ECO4, homeowners need an EPC rating of D to G, and private tenants need E to G. Homes rated A, B or C are not eligible. A council referral through LA Flex also depends on your home’s rating. Your EPC is only part of the check, because household details such as benefits or income also count. Read our ECO4 guide for the full picture.

What if my home has no EPC, or it has expired?

Not every home has a certificate. An EPC is valid for 10 years, and you must have one when you sell or rent out a property or build a new one. If your home has no EPC, or yours has expired, you can get a new one. Tell us what you find and we will explain what is needed.

Found your rating? Here is what to read next

Rated D: see our EPC rating D page.
Rated E: see our EPC rating E page.
Rated F: see our EPC rating F page.
Rated G: see our EPC rating G page.
Rated A, B or C: your home is already efficient. You are unlikely to qualify for ECO4, but you can still ask us about solar panels, batteries and heat pumps.
