EPC register Wales: find an EPC for a Welsh home

There isn't a standalone EPC register Wales keeps just for itself. You search Welsh homes on the same register England uses, through one GOV.UK service offered in English or Welsh.

Search the register for a home in Wales

This opens the GOV.UK service, which is free and holds all Welsh certificates.

How to search the EPC register Wales shares with England

Go to GOV.UK and open Find an energy certificate. A Welsh language (Cymraeg) version of the service is available too.

Start by picking your type of property.
You can search with a postcode, a street name and town, or a certificate number.
Choose the address, and its EPC (Energy Performance Certificate) will open.
Viewing, printing and saving a copy are all free.

Records shared by England and Wales date back to 2008. Even when a certificate expires or gets replaced, it stays on the list.

If no certificate shows up in the results, the home may need a new one. For more search tips, see the EPC register.

When a Welsh home does not appear

It is possible the home has never had a certificate. The owner may also have chosen to opt out of public search, a rule that covers both England and Wales.

Once a request is made, an opted out certificate leaves public view within 2 weeks. Before giving up, try searching by street name and town.

If you still find nothing, getting a new certificate from an accredited assessor is what you will need to do. When you're ready, you can book an EPC.

Rules that match England

The rules for a Welsh home come from the Energy Performance of Buildings (England and Wales) Regulations 2012. That means sellers and landlords face rules just like the ones over the border.

For 10 years a certificate stays valid, and you can reuse it for any sale or let during that time. Before marketing a home, you must order a certificate, and the buyer or tenant then gets a free copy.

Every advert must display the band letter, like C. A fine of £200 per advert can follow if it's missing. To see if the rule covers your home, check do I need an EPC.

Scoring for Welsh homes

The median score for homes in Wales was 68, which is band D. That comes from ONS data covering the 10 years to March 2025. Band C begins at 69, which was England's median.

Welsh homes that are new perform better. For new homes, the median score climbed from 81 to 84 across the earliest and most recent five-year periods.

Where you live makes a big difference to scores. At 80%, Torfaen had the largest share of local areas sitting in band C or above. Not one local area in Conwy reached that level. EPC rating bands explains what each letter means.

The 2030 band C rule and Welsh landlords

Since 2020, homes rented out privately in England and Wales must reach band E. Right now, a landlord has to invest up to £3,500 per property to achieve it.

The government has confirmed band C, a higher standard, for every tenancy, with a deadline of 1 October 2030. Per property, the cap on spending goes up to £10,000.

Until that certificate runs out, a home rated C or higher before 1 October 2029 is treated as meeting the standard. Use the 2030 landlord check to test your own rental, or see EPC for landlords.

EPC Wales help: the Nest scheme

Free energy advice comes from the Welsh Government's Warm Homes Nest scheme if your rating is low. Free home improvements go to some households as well.

Over 60,000 households have received free upgrades through Nest since 2011. Heating systems, insulation and solar panels are among them. Advisers at Nest can point you toward other schemes if you don't qualify. See who qualifies on Nest Wales.
