SEAI Grants 2026: Every Grant Available for Irish Homeowners
Ireland is targeting 500,000 home energy upgrades by 2030. SEAI grants cover a significant portion of the cost for insulation, heat pumps, solar panels, and whole-house retrofits. Here’s the complete list for 2026.
Individual Energy Upgrade Grants
These grants are available for individual upgrades — you don’t need to do a full retrofit. You apply through SEAI.ie after getting quotes from registered contractors.
| Upgrade | Grant Amount | Typical Cost | You Pay |
|---|---|---|---|
| Attic insulation | €1,500 | €2,000–€3,000 | €500–€1,500 |
| Cavity wall insulation | €1,700 | €2,500–€4,000 | €800–€2,300 |
| External wall insulation | €6,000 | €10,000–€18,000 | €4,000–€12,000 |
| Internal wall insulation | €4,500 | €6,000–€12,000 | €1,500–€7,500 |
| Heat pump (air-to-water) | €6,500 | €9,000–€15,000 | €2,500–€8,500 |
| Heat pump (ground source) | €6,500 | €14,000–€22,000 | €7,500–€15,500 |
| Solar PV panels | €2,100 | €5,000–€9,000 | €2,900–€6,900 |
| Solar water heating | €1,200 | €3,000–€5,000 | €1,800–€3,800 |
| Heating controls | €700 | €1,000–€2,000 | €300–€1,300 |
| Window upgrades | €4,000 | €6,000–€12,000 | €2,000–€8,000 |
One Stop Shop Retrofit Grants
For a whole-house approach, SEAI’s One Stop Shop service coordinates your entire retrofit through a registered project manager. The goal is to bring your home to a BER B2 rating or better.
- Grants of up to €25,000 (or more for larger homes) covering multiple upgrades
- A dedicated project manager handles everything: assessment, planning, contractor coordination, grant applications
- Typically includes insulation + heating system + ventilation + windows as a package
- Your home must achieve a BER B2 or better after the work
BER Assessment Grant
A BER assessment is required before applying for most SEAI grants. The assessment costs approximately €150–€200 + VAT. While there is no standalone BER grant, the cost is included as part of any One Stop Shop retrofit package.
Landlord-Specific Grants
Landlords can access the same SEAI grants as homeowners. Additionally, Budget 2026 extended the tax deduction for retrofitting costs for small landlords to the end of 2028. This means the cost of energy upgrades on your rental property can be deducted from your rental income for tax purposes — on top of the SEAI grant.
