For an SEAI heat pump grant, your home generally needs a valid BER and a technical assessment to show that a heat pump is suitable; the assessment may also identify insulation or ventilation improvements. Apply to SEAI and receive approval before any grant-supported work begins, then use an SEAI-registered contractor to install the system. A post-works BER or other documents may be required before payment. Requirements and grant values can change, so check the latest SEAI guidance and confirm the process with your registered contractor; SEAI makes the final eligibility decision.
