About this scheme
The Heat Pump Grant, delivered under SEAI's Support Scheme for Renewable Heat (SSRH) investment aid, helps businesses switch from fossil fuel heating to renewable heat pump technology, increasing energy efficiency, reducing heating costs, and lowering carbon footprint. SEAI offers an installation grant of up to 40% for air source, ground source and water source heat pumps, and for mechanical vapour recompression systems, with a slightly lower 35% grant available for Geothermal Heating Systems. An additional 30% grant is available for related energy efficiency measures, such as heat recovery, ventilation, or building fabric works, undertaken alongside the heat pump installation. SEAI recommends carrying out an energy audit and engaging an energy consultant or sustainability manager before applying, as they can help assess suitability and guide the SSRH application. Applications are made online via SEAI's Project Evaluation Platform (PEP), following the scheme's Terms and Conditions and grant scheme operating rules.
