Find an EPC assessor near you
Only an accredited domestic energy assessor can produce a valid EPC. Finding one takes 5 minutes; here is the route, the cost, and what to ask.
The official directory
The government keeps the register of accredited assessors, searchable by postcode: gov.uk/get-new-energy-certificate. Every assessor listed there belongs to an approved accreditation scheme, which handles their training, insurance and complaints. An assessor who is not on that register cannot lodge a certificate, whatever their ad says.
What it costs and how the visit works
A domestic assessment typically costs £35 to £120 depending on property size and region; our EPC cost guide breaks down what moves the price. The visit takes 30 to 60 minutes: the assessor measures the property and records insulation, heating, glazing and lighting, then lodges the certificate on the national register, usually within a few days. It appears in our EPC checker at the next monthly refresh, and on gov.uk straight away.
Worth asking before you book
- The price, fixed, for your property size. The spread between local quotes is often £30 or more.
- How soon they can visit and how soon they lodge. Some lodge same-day, some take a week.
- Whether they will credit improvement evidence. If you have invoices for insulation or a new boiler, the assessor can only count what they can see or verify, so having paperwork ready protects your score.
- For a rental heading to market: whether they can also advise on reaching band C, since some assessors offer improvement reports alongside the certificate.
Commercial property
Non-domestic EPCs need a different qualification. The same gov.uk search covers commercial assessors; expect prices from about £150 and rising with floor area.
Before booking at all, check whether the property already has a valid certificate; it lasts 10 years. Look it up free with the EPC checker or on gov.uk.
