Start by choosing the right grant route: individual measures, a managed One Stop Shop project, or fully funded Warmer Homes upgrades. A listed amount is a grant limit, not a price quote or approval.
This guide compares the main routes and links to the relevant schemes. Source dates beside figures are separate from this article’s review date. Manually researched values are not refreshed by every daily data run.
Not sure what you qualify for? Our SEAI grant eligibility checker helps you explore possible grants. It cannot assess all scheme conditions or approve a combined award.
Who is eligible for SEAI grants?
Use the SEAI home-grants overview to choose the route. Property-age cutoffs and occupancy conditions vary by scheme. Do not apply one universal pre-2011 rule to solar PV and heat pumps, or assume that landlords cannot apply.
Approval must be in place before works start. Check the registered-contractor requirements, previous grant history and supporting documents for the specific measure. The Warmer Homes Scheme has separate household eligibility and survey requirements.
Choose a route before comparing quotes
| Route | Planning question |
|---|---|
| Individual grants | Can you coordinate the contractors and fund the gap before payment? |
| One Stop Shop | Does the full proposal meet the scheme target and include all required work? |
| Warmer Homes | Does your household meet the payment and ownership conditions? |
Ask for the gross project cost, the proposed grants and any exclusions on separate lines. Keep an application checklist with the quote so you can distinguish an estimate from an approval.
Heat pump grants
Air-to-water heat pumps are the most commonly installed renewable heating system in Ireland. See our heat pump grant guide for the application detail, or what a heat pump costs to install in Ireland for the figures before grant.
| Grant | House | Apartment |
|---|---|---|
| Air-to-water heat pump (unit) | €6,500 (manual, 2026-09-22) | €4,500 (manual, 2026-06-12) |
| Central heating system | €2,000 (manual, 2026-09-22) | €1,000 (manual, 2026-06-12) |
| Renewable heating bonus | €4,000 (manual, 2026-09-22) | €4,000 (manual, 2026-09-22) |
| Air-to-air heat pump | €7,500 (manual, 2026-09-22) | €7,500 (manual, 2026-09-22) |
| Technical assessment | €200 (manual, 2026-09-29) | €200 (manual, 2026-09-29) |
The renewable heating bonus (€4,000 (manual, 2026-09-22)) is available when you switch from an oil, gas, solid fuel or qualifying electric-storage heating system to a heat pump. If your home is a pre-2011 build with solid walls, read SEAI grants for old houses first, since the insulation works usually have to come before the heat pump. This brings the maximum combined heat pump grant for a house to €6,500 (manual, 2026-09-22) + €2,000 (manual, 2026-09-22) + €4,000 (manual, 2026-09-22) = €12,500 (manual, 2026-09-22).
Solar PV grants
The solar PV grant scales with system size:
| System size | Grant |
|---|---|
| 1 kWp | €700 (manual, 2026-06-12) |
| 2 kWp | €1,400 (manual, 2026-06-12) |
| 3 kWp | €1,600 (manual, 2026-06-12) |
| 4 kWp+ | €1,800 (manual, 2026-09-22) (maximum) |
Work out what a system returns with the solar payback calculator, and see solar panel costs in Ireland for installed prices.
Solar water heating (thermal, not PV) carries a separate grant of €1,200 (manual, 2026-06-12).

Grant amounts vary by dwelling type and whether you are a first-time buyer (FTB). Our insulation grants guide covers the qualifying standards for each measure.
Attic insulation

| Apartment | €1,100 (manual, 2026-06-12) | €1,400 (manual, 2026-06-12) |
Attic insulation is usually the cheapest measure to start with.

|---|---|---|---|---|
| Cavity wall | €1,800 (manual, 2026-06-12) | €1,300 (manual, 2026-06-12) | €850 (manual, 2026-06-12) | €700 (manual, 2026-06-12) |

Which one applies depends on your walls. Compare cavity, internal and external options in wall insulation types.

A BER is the measure of how your home performs today. Read BER ratings explained for what each band means, and the EV charger grant for the installation rules.
How to apply
Our step-by-step guide to applying for an SEAI grant walks through both routes, and One Stop Shop vs individual grants compares them.
Individual grants: apply online at seai.ie before works start. You’ll receive approval, then hire a registered contractor.
One Stop Shop: find an approved OSS provider at seai.ie/one-stop-shop. They manage the entire project and grant application.
Always check the SEAI website for the most current amounts and any scheme changes.
