A BER assessment for selling a house commonly costs around €100–€300, although the fee can vary with the property’s size, location and the assessor’s rates. You must have a valid BER certificate before advertising the property for sale, and the BER rating should appear in the listing. The certificate is generally valid for up to 10 years unless significant changes affect the home. Check that your assessor is registered with SEAI and confirm the total fee, including VAT, before booking.
