Home energy upgrade grants in Ireland are SEAI supports that may help with the cost of improving a home’s energy efficiency, such as insulation, heat pumps, solar PV and heating controls. You can generally apply for individual upgrades or use an SEAI-registered One Stop Shop, which manages several measures as part of a wider renovation. The support available and your eligibility can depend on the property, its BER, the work planned and your circumstances, so approval is not automatic. Check the latest rules on the official SEAI website and use a registered contractor before starting work.
