Irish Heat Pump Grant Statistics & 2030 Target Progress
Official statistics on SEAI grant-aided heat pump installations in existing Irish homes under the National Retrofit Plan. Source: Sustainable Energy Authority of Ireland. Data to 31/07/2026.
SEAI Heat Pump Retrofit Grant Uptake by Year
Grant-supported heat pump installations in existing dwellings expanded from 211 units in 2018 to 4,167 units in 2025, bringing the all-time total to 21,446 units:
Progress Towards the 2030 Heat Pump Target
Under Ireland's Climate Action Plan, the government has set a target of installing 400,000 heat pumps in existing residential dwellings by 2030 to replace fossil-fuel heating systems (oil, gas, and solid fuel boilers).
- Total 2030 Target: 400,000 heat pump installations in existing homes
- Achieved to date: 21,446 installations (5.4%)
- Remaining to achieve: 378,554 installations
The line chart below models cumulative heat pump retrofits through 2030 based on the current annual run rate (4,167 units/year) relative to the 400,000 target:
* Projected trend (2026–2030) continues the latest confirmed annual pace (4,167 units/year). At this run rate, cumulative retrofits would reach roughly 39,278 units by year-end 2030 (9.8% of the 400,000 target).

About SEAI Heat Pump Retrofit Grants
Under the SEAI Heat Pump Systems Grant scheme, support is structured as a bundle of up to three individual grants offering up to €12,500 for houses and €9,500 for apartments (€7,500 for air-to-air systems):
- Heat Pump Unit Grant: Up to €6,500 for houses (€4,500 for apartments) for wet central heating systems, or €3,500 for air-to-air systems.
- Central Heating Upgrade Grant: Up to €2,000 for houses (€1,000 for apartments) for necessary radiator, pipework, or underfloor heating upgrades.
- Renewable Heat Bonus Grant: €4,000 for homeowners replacing an existing fossil fuel heating system (oil, gas, or solid fuel boiler) or electric storage heating with a heat pump.
Maximum combined grant amounts vary by heat pump technology and dwelling type:
| Heat Pump System / Measure | Apartment | Mid-Terrace | Semi-Detached / End-Terrace | Detached |
|---|---|---|---|---|
| Air-to-Water Heat Pump Extracts heat from ambient outside air for wet central heating & hot water |
€9,500 | €12,500 | €12,500 | €12,500 |
| Ground-Source (Ground-to-Water) Geothermal collector loops in trenches or boreholes |
€9,500 | €12,500 | €12,500 | €12,500 |
| Exhaust Air-to-Water Extracts heat from mechanical extract ventilation with heat recovery |
€9,500 | €12,500 | €12,500 | €12,500 |
| Water-to-Water Heat Pump Extracts heat from open water source or well water |
€9,500 | €12,500 | €12,500 | €12,500 |
| Air-to-Air Heat Pump Distributes heat via warm air blowers (ductless split units; no domestic hot water) |
€7,500 | €7,500 | €7,500 | €7,500 |
| Technical Assessment Pre-install Heat Loss Indicator (HLI) survey where required |
€200 | €200 | €200 | €200 |
* Technical assessment (€200 grant) is required for pre-2007 dwellings unless a valid BER confirms a Heat Loss Indicator (HLI) of ≤ 2.3 W/(K·m²). Homes built from 2007 onwards qualify via a Self-Declaration form. Replacing an existing heat pump (not previously grant-aided) qualifies for up to €6,500 (€4,500 for apartments) for the unit only (excluding the Renewable Heat Bonus and Central Heating grants). Grants cannot exceed the total cost of works.
