What is an EPC certificate?
An EPC certificate (Energy Performance Certificate) rates how energy-efficient a property is, from A (most efficient) to G (least efficient). It estimates typical running costs and recommends improvements, and it is legally required whenever a home in England and Wales is built, sold or let.
Every EPC certificate is valid for 10 years and must be produced by an accredited Domestic Energy Assessor. Whether you are a homeowner planning upgrades or a landlord preparing for the 2030 EPC C deadline, the guides below explain what your rating means, what an EPC certificate costs, and how to improve it — all in plain English.

Official sources and guidance
EPC certificates are a legal requirement under UK law. For the official position, see the GOV.UK guidance on Energy Performance Certificates when buying or selling a home and the domestic private rented property minimum energy efficiency standard. The confirmed EPC C requirement for rented homes from 1 October 2030 is set out in the government’s response on improving the energy performance of privately rented homes.
To arrange a new EPC certificate, use the official Find an Energy Assessor service to locate an accredited assessor in your area. The reformed EPCs based on the Home Energy Model are due in H2 2027, as described in the government’s reforms to the Energy Performance of Buildings regime.
