Check EPC rating: search the EPC register in the UK
For an EPC rating check or EPC certificate check in the UK, use the official register first. In England, Wales and Northern Ireland, search the GOV.UK EPC register by postcode, street name and town, or certificate number. In Scotland, use the Scottish EPC Register.
An EPC is normally valid for 10 years, but if the property has changed a lot since it was issued, the old record may no longer be a useful guide. Use the main Energy Performance Certificate guide if you want the broader explanation as well. · 3 min read
How to search the EPC register in England, Wales and Northern Ireland
- Choose a domestic property for a house or flat.
- Search by postcode, street name and town, or certificate number.
- Select the exact address, including the flat number if there is one, then open the certificate.
Check the current rating and valid-until date. The potential rating describes improvements that could be made; it is not the home's rating today. Read the recommendations and the recorded wall, roof and heating details before planning work.
How to check EPC rating in Scotland
Open the Scottish EPC Register and choose Search EPC. The Scottish Government explains the process in its EPC guidance.
Search by postcode or the report reference number (RRN). If the property has an active Green Deal plan, use the RRN; it will not appear in a postcode search.
If the record is missing or out of date, the Scottish Government says the next step is to get an EPC assessor through the Scottish EPC register route.
How to tell if the EPC is still valid
For England, Wales and Northern Ireland, GOV.UK says an EPC is normally valid for 10 years. The Scottish Government says the same for Scotland.
Look at the issue date, then ask whether the property has changed since then. New windows, added insulation, heating-system changes, or extensions can make the older record less useful.
If a postcode search finds nothing, try the street name and town or the certificate number from an existing copy. Check for a different flat number or address format. For a recently completed assessment, ask the assessor whether it has been lodged. If you need a valid EPC and none is available, use the official assessor search to arrange a new assessment.

After the EPC check, move the job into the right survey route
For installer teams, an EPC check is usually the first filter. Once the rating is known, the live question is what evidence the job needs before anyone quotes, designs, or books an install too far ahead.
Heat pump survey company
Use this route when the EPC check points towards low-carbon heating work and the team needs site notes before design or quote review.
Heat loss survey company
Use the heat loss route when the job needs clearer room data, fabric notes, emitter context, and a report that the next person can follow.
Solar panel survey company
Use the solar route when the EPC is part of a wider PV conversation and the installer needs photos, access notes, roof context, and clear site evidence.
