There is not usually one specific BER rating that guarantees eligibility for an SEAI heat pump grant. Your home must meet SEAI’s requirements, which can include a suitable heat-loss assessment, the age and type of property, and installation by an approved contractor. A BER assessment may be needed before and after the work, but the BER alone does not decide whether a grant is available. Check the latest criteria on the SEAI website and ask a registered heat pump contractor to assess your home.
