SEAI heat pump support may be available in 2026 for homeowners replacing a gas boiler, but eligibility depends on the property, its age, insulation and the results of a technical heat-loss assessment. A heat pump must be correctly sized and installed by an SEAI-registered contractor, and you may need to complete the grant application before work begins. The grant amount and approval are decided under the applicable SEAI rules, so they are not guaranteed. Check the latest details on the official SEAI website and ask a registered contractor to assess your home.
