When you use SEAI’s One Stop Shop, the grant is deducted from the price rather than repaid to you later. What you save depends on your house type and the measures in your plan. Here are the SEAI figures in one place, followed by a worked example.
Grant values by measure and house type
All amounts are in euro, from SEAI’s One Stop Shop page.
| Measure | Detached | Semi-D / end terrace | Mid-terrace | Apartment |

| Heat pump system | 10,500 | 10,500 | 10,500 | 8,500 |
| Central heating upgrade for heat pump | 2,000 | 2,000 | 2,000 | 1,000 |
| Boiler scrappage | 2,000 | 2,000 | 2,000 | 2,000 |
| Air-to-air heat pump | 7,500 | 7,500 | 7,500 | 7,500 |

| Attic insulation (first-time buyer / other) | 2,500 / 2,000 | 1,900 / 1,500 | 1,800 / 1,400 | 1,400 / 1,100 |
| Rafter insulation | 3,000 | 3,000 | 2,000 | 1,500 |

| Windows (complete upgrade) | 4,000 | 3,000 | 1,800 | 1,500 |
| External doors (max 2) | 800 per door | 800 per door | 800 per door | 800 per door |
| Floor insulation | 3,500 | 3,500 | 3,500 | 3,500 |
| Solar thermal | 1,200 | 1,200 | 1,200 | 1,200 |
| Mechanical ventilation | 1,500 | 1,500 | 1,500 | 1,500 |
| Air tightness | 1,000 | 1,000 | 1,000 | 1,000 |
| Home energy assessment | 350 | 350 | 350 | 350 |
| Project management | 2,000 | 1,600 | 1,200 | 800 |
Solar PV is €700 per kWp up to 2 kWp, then €1,400 (2 kWp), €1,600 (3 kWp) and €1,800 (4 kWp), the same for every house type and capped at €1,800.
Notes SEAI attaches to the table
- The higher attic grant applies only to qualifying first-time buyers: you own and live in the home, bought a second-hand home on or after 1 January 2025, and have not previously bought a home. It applies to the attic measure only.
- A replacement heat pump, where the existing unit was never grant-aided, is capped at €6,500 (€4,500 for apartments), and is not eligible for the boiler scrappage or central heating grants.
- Homes built before 1940 can apply through a pilot, but only certain One Stop Shops offer it.
Worked example: a semi-detached house
This is an illustration, not a quote. Take a semi-detached house with a heat pump, central heating upgrade, boiler scrappage, standard attic insulation and cavity wall insulation, plus the assessment and project management:
| Item | Grant (€) |
|---|---|
| Heat pump system | 10,500 |
| Central heating upgrade | 2,000 |
| Boiler scrappage | 2,000 |
| Attic insulation (non-first-time buyer) | 1,500 |
| Cavity wall insulation | 1,300 |
| Home energy assessment | 350 |
| Project management | 1,600 |
| Total grants | 19,250 |
If the One Stop Shop’s total quote for that package were €35,000 (hypothetical), the grants of €19,250 would be taken off the invoice, leaving €15,750 for you. Real quotes vary, so compare several providers and see our One Stop Shop vs individual grants guide for the cash-flow trade-offs.
Who can apply, and what is excluded
SEAI lists homeowners, first-time buyers, private landlords and approved housing bodies (which have separate amounts). Excluded are homes that previously received SEAI grants for the same measures and homes that have received energy credits through the Energy Efficiency Obligation Scheme (EEOS).
The BER target
After the works, the home must reach at least BER B and either install a heat pump or achieve a primary energy uplift of 100 kWh/m²/yr. The One Stop Shop works this out for you, starting with a Home Energy Assessment, which has its own €350 grant. For individual measures, see the heat pump grant guide and the wall insulation guide.
