Attic insulation grant in Ireland (2026)

Enhanced support is up to €2,500 for eligible first-time buyers, homeowners on qualifying welfare payments or eligible active HAP/RAS properties.

Source: SEAI attic insulation grant page, checked 25 September 2026. Each amount is fixed, but the grant can never be more than the cost of the work.
SEAI raised the attic grant on 3 February 2026. A house loses 20 to 30% of its heat through the roof, which is why SEAI calls attic insulation often the most cost-effective upgrade you can make.
The higher rates cover eligible first-time buyers, homeowners on qualifying welfare payments and eligible active HAP/RAS properties. For HAP/RAS, the home must be built and occupied by 31 December 2010; SEAI may require evidence of the active tenancy or arrangement and verify the application. Check SEAI’s attic eligibility rules.
The higher attic grant for first-time buyers
You get the higher amount automatically if all of these apply:
- You are a first-time buyer of an existing home.
- The home was built and occupied on or before 31 December 2010.
- You bought it on or after 1 January 2025.
You declare that you are an eligible first-time buyer in the online application, and SEAI may check it. The higher first-time buyer amount applies to attic insulation only. Homeowners on qualifying welfare payments get the same higher attic amounts, and a higher cavity wall grant too.

Check my grantsDoes my home qualify?
- Age of the home: built and occupied before 2011.
- Electricity meter: the home needs an MPRN, and there must be no earlier SEAI attic insulation grant at that MPRN.
- Apartments: only top-floor apartments, or apartments where heat escapes through the roof. An apartment with another apartment directly above it does not qualify.
- Who can apply: owner-occupiers, first-time buyers, homeowners on qualifying welfare payments, landlords, holiday home owners, companies, owner management companies, registered charities and approved housing bodies.
- Traditional homes: older solid-wall homes (typically built before 1940) can still apply for the attic grant.
What does attic insulation cost?
Semi-detached or end of terrace
SEAI median cost: €2,101
Mid-terrace
SEAI median cost: €2,200
Apartment
SEAI median cost: €1,515
These are SEAI’s median costs for grant-aided attic insulation completed from January to June 2026. Set against the standard grant, the difference is roughly €400 to €800, but your quote depends on the attic size, access, any storage boarding, and whether it is ceiling-level or rafter insulation.
You pay the contractor in full and SEAI pays the grant into your account once the work is done and the paperwork is in. Some registered contractors take the grant off their price instead: you then name their bank account for the grant on SEAI’s payment form. Ask when you get quotes.
