A domestic Energy Performance Certificate should be prepared by an accredited assessor. Before booking, ask who will attend and check that their accreditation covers domestic EPC assessments.

Use the official assessor service

GOV.UK offers a way to find an accredited assessor for England, Wales and Northern Ireland. Scotland uses a separate process. You can also ask a matching provider for the assessor's name and accreditation scheme so you can verify the details.

Ask what is included

Confirm that the visit and lodgement of the finished EPC are both included in the quote. Ask when the assessor can attend and when to expect the lodged digital certificate. A general surveyor credential on its own does not establish the required EPC qualification.

After the assessment

Check the finished certificate on the relevant official register. If the property already has a valid EPC, you can check that before commissioning a fresh visit.

A useful verification sequence

Start by confirming whether the certificate is for a domestic home, since a business property can call for a different kind of assessment. Request the name of the individual assessor, not just the booking company. Check their accreditation through the official route for the nation where the property sits, then confirm the quote includes a visit and lodgement. Ask the provider to clarify any mismatch before you pay.

What exactly are you verifying?

Check that the individual who will inspect the home is accredited for domestic energy assessments. A business may employ several professionals with different qualifications. Being a chartered surveyor, estate agent or property manager does not by itself establish that the individual may produce a domestic EPC. Ask for the assessor's name and accreditation scheme before you accept the booking.

Official services and national differences

The GOV.UK 'Get a new energy certificate' service links to the accredited assessor search in England, Wales and Northern Ireland. For a property in Scotland, use the separate Scottish process linked there. If a provider matches you with someone, compare the details you are given with the appropriate official route. Check that the provider is offering a domestic EPC if the property is a home, rather than a commercial certificate for business premises.

Why accreditation matters after the visit

The assessment has to be lodged so that the certificate can be retrieved from the relevant register. Ask when you should expect that step to be completed and where you will find the digital certificate. If details on the finished EPC appear wrong, contact the assessor first and then their accreditation scheme if necessary.

Useful questions to ask on the phone

Who is the named assessor? Which scheme are they accredited through? Is the quote for this exact property address and type? Does the total include lodgement and travel? What is the earliest confirmed visit? These questions provide more useful assurance than a generic claim that the provider is 'fully qualified'.
