SEAI maintains Ireland’s National BER Register, where you can search for published BER certificates using details such as a property address or certificate number. It can help you compare ratings, energy performance indicators and certificate dates, although the results may not provide a complete picture of a home’s condition, heating habits or running costs. Check that you are comparing similar property types and note whether a certificate is current. For a detailed interpretation of a specific rating, ask an SEAI-registered BER assessor or consult the official SEAI website.
