SEAI heat pump grants may help with the cost of replacing a gas boiler, but eligibility depends on factors such as the home’s age, insulation, heat-loss assessment and the proposed system. A registered contractor must usually assess the property and confirm whether it is suitable before work starts. Total installation costs can run to several thousand euro, with the final price affected by insulation upgrades, radiators, hot-water systems and electrical work, so the grant may not cover the full amount. Check the latest grant rules on SEAI’s official website and obtain written quotes from registered installers.
