The SEAI National BER Register is the main online database for checking a home’s Building Energy Rating in Ireland. You can usually search using details such as the property address, BER number or MPRN, where available, to view the rating and certificate information. The listing may also show the certificate date, energy performance indicator and advisory report, although records can vary. If you cannot find a property, ask the owner, seller or landlord for the certificate and check the official SEAI website for the latest search guidance.
