SEAI heat pump grant eligibility is not based solely on reaching one fixed BER rating. Your home normally needs a pre-works BER assessment and a technical assessment confirming that its heat loss is suitable for a heat pump; if it is poorly insulated, upgrade work may be needed first. A low BER does not automatically rule you out, but the technical assessment may identify insulation or ventilation improvements before an application can proceed. Requirements and grant decisions depend on your property and the current SEAI rules, so check the latest guidance or speak to an SEAI-registered contractor.
