Domestic EPC before selling or letting a London home: the practical sequence

Start with the address, not an appointment

A domestic Energy Performance Certificate (EPC) is usually needed before a home is marketed for sale or rent. First search the official energy certificate register using the property address. A certificate is normally valid for 10 years, although a newer EPC replaces an older one. If a usable record already exists, downloading it may be the quickest route.

Check that the certificate matches the home being marketed

A flat number, converted unit or changed address can make a register search less straightforward. Compare the address and property description on any result with the home you intend to market. If the building has been divided or substantially changed, explain that before ordering an assessment rather than assuming an old certificate covers the present unit.

Prepare the property for an efficient EPC visit

An accredited assessor needs access to the rooms and relevant fixed features. Make sure an occupier can let them in and point out heating controls, the boiler, loft access and any evidence of insulation or glazing improvements. Provide documentation for work that may not be visible; an assessor cannot simply assume that hidden improvements exist. The visit records the home as assessed, rather than a planned future specification.

Use the result for the right decision

The A-to-G rating and recommendations help buyers or tenants understand energy performance. An EPC is not a structural survey, gas safety check or electrical inspection. If you need several documents for a tenancy, arrange each separately and keep their dates and addresses together.
