Energy Performance Certificates from the MHCLG register, retrieved 27 October 2026. A certificate describes the property on the day it was inspected, under a standard assessment — not the bills you would pay, and not the state of it now. Greathome does not claim any of these is the property you are looking at; the register has no address key we can trust for that.

Understand a property’s energy evidence

Search the connected energy-certificate records and check which certificate belongs to the property you are considering.

How the tool works

  1. Search the postcode and inspect the addresses returned.
  2. Check certificate dates and identifiers before selecting a record.
  3. Read the published rating and recommendations in the context of the assessment date.

When to use it

Use EPC research before a viewing or when considering energy improvements. It helps organise questions for the seller, landlord or assessor.

UK coverage and assumptions

The connected open-data service covers England and Wales. A certificate is a dated energy assessment, not a structural survey or a prediction of your household’s bills.

Frequently asked questions

Does a better rating guarantee lower bills?

No. Energy use depends on occupancy, heating choices, tariffs and changes since assessment. The rating uses a defined methodology rather than your personal consumption.

Can several certificates exist for one address?

Yes. Check dates and identifiers and whether a newer assessment exists. An old record may have been replaced or expired.

Does the postcode confirm the property match?

No. A postcode can contain many homes. Match the exact address or relevant identifier before using floor area or certificate details.
