The SEAI attic insulation grant
SEAI's individual grant for roof insulation is for the attic floor: €2,000 for a detached house, €1,500 for a semi-D or end of terrace, €1,400 for a mid-terrace and €1,100 for a top-floor apartment, with higher amounts for first-time buyers of an older home and some people on welfare payments. Rafter and room-in-roof insulation are grant-aided only as part of a One Stop Shop whole-home upgrade.

- The contractor is registered with SEAI and works to SEAI's technical standard.
- Approval comes first. Apply online, get the grant offer, then book the work. Work started before approval doesn't qualify.
- Payment after. The contractor submits the declaration of works, you claim, and SEAI pays you.

Claiming it, step by step

- Get a quote from an SEAI-registered contractor, for the attic floor to SEAI's standard.
- Apply online with SEAI and wait for the grant offer. Don't start or book the work before it.
- Have the work done by that registered contractor.
- Claim. The contractor completes the declaration of works, you submit the payment request, and SEAI pays the grant to you.
On a semi-D the grant of €1,500 leaves about €300 to €601 to pay: attic insulation cost.
Plan your roof insulation
A few quick taps, and your plan fills in as you answer: the right method for your roof, what it costs, the grant and the standard to ask for. Contact details come last, and only if you want a contractor to price it.
Attic floor insulation, semi-d or end of terrace: €1,800 to €2,101 before the €1,500 SEAI grant, so about €300 to €601 to pay.
How the estimate is worked out
Attic floor insulation uses what SEAI-registered contractors were paid for each kind of home in 2026 and what an Irish installer charges, with the SEAI grant taken off. A room in the roof and a flat roof are priced per m² of the area you enter: rafter boards with a plasterboard finish, or a warm roof with a new membrane. VAT is included. Use it to plan with. It isn't a quote: a contractor prices your roof after a survey.
Rafters, rooms in the roof and flat roofs
SEAI has no individual grant for these. They can be grant-aided as part of a whole-home upgrade through a One Stop Shop, which manages the work, applies for every grant together and needs the home to reach a BER of B2 or better at the end. That suits a house getting walls, windows and heating done as well.
The Warmer Homes Scheme gives fully funded upgrades, including attic insulation, to people on certain welfare payments, through SEAI.
