Start by checking SEAI’s current heat pump grant rates and confirming that your home and applicant type appear to meet the basic requirements. Next, ask an SEAI-registered contractor to carry out the required technical assessment, including a heat-loss calculation, and provide a written quote. Review which parts of the work may be supported, such as the heat pump system, heating controls or associated upgrades, then subtract any applicable grant limits from the quoted cost. Apply through the official SEAI process before work begins; the approved amount ultimately depends on SEAI’s assessment and your individual circumstances.
