Who can carry out an EPC?
An accredited energy assessor qualified for the type of building produces an EPC. Start with the official assessor service and verify the assessor’s accreditation-scheme membership before booking.

Find and check an assessor
An ordinary existing-home EPC is carried out by an accredited domestic energy assessor. New-build work needs an assessor with the appropriate on-construction competence. A job title such as surveyor or estate agent does not by itself demonstrate accreditation, although someone with that job may also hold the required qualification.
Find an accredited assessor on GOV.UKEnter any address only on the government service. It covers England, Wales and Northern Ireland; GOV.UK links separately to Scotland. EPC Benchmark’s comparison remains for England and Wales only.
Useful questions before booking
These are practical questions from EPC Benchmark, not a list of mandatory booking requirements.
| Question | What to check |
|---|---|
| Who will assess the home? | Ask for the named assessor and check their current accreditation-scheme membership. |
| What does the fee include? | Ask about the assessment, certificate lodgement and delivery, and any revisit terms. |
| What access and evidence should I prepare? | Ask before the visit about rooms, a safely accessible loft, heating equipment and useful documents. |
| When should I expect the certificate? | Confirm timing directly with the assessor; this guide does not promise a standard turnaround. |
Prepare useful access and evidence
The assessor records physical features, observations and acceptable supporting evidence. Ask whether insulation installation documents, glazing certificates, and heating make, model, manuals or installation dates would be useful. The assessor decides what can be accepted and may use an assumption where evidence or safe access is unavailable. Share documents directly with the assessor; EPC Benchmark does not receive uploads.
First, check the existing certificate and its date. The validity guide explains when an older record may still be current; there is no universal instruction here to renew it.
Takeaway
Use the official service, verify accreditation and agree the scope before booking. EPC Benchmark does not issue certificates, recommend individual assessors or receive referral fees.
