You can find BER assessors in your area through the official SEAI register, which lets you search by location and contact details. Ask for a written quotation, confirm that the assessor is registered for domestic properties, and check what documents or access they need. The assessment usually involves an inspection of the home’s construction, insulation, heating, ventilation and windows, but the final BER rating depends on the property and information available. GrantWise is independent, so check current requirements and assessor details directly with SEAI before arranging an assessment.
