What changed in 2026
2026 was a major year for SEAI grants — applications rose sharply after several increases. The headline changes:
Heat pump grant raised to €12,500
From 3 February 2026 the heat pump system grant rose from €6,500 to up to €12,500 — the existing €6,500 plus €2,000 for radiators and pipework and a new €4,000 renewable heating bonus.
Insulation grants increased
Cavity wall and attic insulation grant amounts were increased in 2026, making fabric-first upgrades cheaper for more homeowners.
New windows & doors grant
From 2 March 2026, SEAI introduced a dedicated windows and doors grant — windows up to €4,000 by house type, plus €800 per external door up to two doors.
Second wall measure now allowed
From 2 March 2026, homeowners who previously claimed a wall insulation grant can now apply for a grant towards a second wall measure.
Who qualifies for SEAI grants in 2026?
The general rules
- Insulation, windows & doors, heating controls: home generally built and occupied before 2011.
- Heat pump & solar PV: home generally built before 2021.
- Ownership: you own the home (or have the owner’s consent), and it’s your home rather than a new build.
- Registered contractor: grant work must be done by an SEAI-registered contractor.
- BER: a post-works BER assessment is required for most measures.
The fully-funded route
The Warmer Homes Scheme can fully fund insulation and heating upgrades where someone in the home receives a qualifying payment, such as:
- Fuel Allowance
- Working Family Payment
- One-Parent Family Payment
- Carer’s, Disability or Domiciliary Care Allowance
Whether your specific home and circumstances qualify — and for which grants — is what the checker works out for you.
How to apply for an SEAI grant
The application route is the same for most individual grants. The single most common reason grants are refused is starting work before SEAI approval — so the order matters.
1. Check what suits your home
Confirm which upgrades your home is eligible for, by age, type and BER, before committing to any work.
2. Get an SEAI-registered contractor
Grant work must be done by a contractor on the SEAI registered list. Get a written quote first.
3. Apply before work starts
Submit your application through SEAI and wait for approval. Starting early is the top reason grants are refused.
4. Do the work + post-works BER
Complete the upgrade, then arrange the post-works BER assessment where it’s required.
5. Get paid
Once SEAI verifies the completed work, the grant is paid to you or applied as agreed.
Do it in the right order
Fabric-first — insulation before a heat pump — usually saves money and protects later grants. The best order depends on your home.
