Eligibility for an SEAI air source heat pump grant can depend on factors such as when your home was built, its existing heating system, insulation levels and the results of a technical assessment. You generally need to use an SEAI-registered contractor, and you should confirm the application process before starting any work. The grant amount and approval are decided by SEAI based on your individual circumstances and the proposed system. Check the latest requirements on the official SEAI website or ask a registered contractor to assess your home.
