The quick way

  1. Go to the official Find an energy certificate service on GOV.UK.
  2. Search by postcode, by street name and town, or by certificate number (GOV.UK).
  3. Pick your address. The certificate rates the home from A (best) to G (worst) and gives typical energy costs and steps to improve (GOV.UK).
  4. Type the score into the calculator above to see how far you are from the next band.

Looking up and downloading an existing certificate is free (GOV.UK). There is no need to pay a third-party site to see it.

Which register for which country

Property in Where to look
England and Wales Find an energy certificate
Northern Ireland The same GOV.UK service, which covers England, Wales and Northern Ireland. nidirect also points to a Department of Finance search by postcode (nidirect)
Scotland The separate Scottish EPC Register. GOV.UK says Scotland has "a different service"

Reading what you find

  • The letter and the number. The number is the score, the letter is the band it falls into: C is 69 to 80, D is 55 to 68. See EPC bands explained.
  • The date. An EPC is valid for 10 years (GOV.UK). Check the expiry date before you rely on a certificate for a sale or a new let.
  • More than one certificate. If a home was assessed more than once, check the most recent valid one. Works done since the last assessment are not reflected until someone does a new one.
  • The recommendations. GOV.UK says the certificate sets out steps to improve the home's efficiency and save money. They are your starting point for reaching band C.

No certificate found?

GOV.UK says that if the property has no certificate, or it has expired, you can get a new one (GOV.UK). Before that:

  • try the postcode with and without the space, then search by street and town;
  • try the old address if the building was renamed, split into flats or renumbered;
  • for help finding a certificate, use the contact details on the GOV.UK find an energy certificate service (MHCLG, Monday to Friday, 9am to 5pm).

Getting a new EPC

You pay an accredited assessor for it, and the cost "varies by assessor and the size of the property" (GOV.UK). Find one through the GOV.UK assessor search, then check that they belong to an accredited scheme. An EPC must be ordered before a home is marketed for sale or rent, and you can be fined if you do not get one when you need it (GOV.UK).

Checking a landlord or a home you might rent

The same register shows the rating of any address with a certificate, so tenants and buyers can look a home up before a viewing. For rentals, the PRS Exemptions Register shows registered exemptions and penalties (GOV.UK). A let home rated F or G with no exemption is a warning sign: see EPC F and G.
