Grant check
Your attic grant and what's left to pay
Two taps: your home, and which rate fits you. The answer is SEAI's fixed grant and its own median cost for the job.
Your SEAI attic insulation grant
€1,500
- SEAI median cost, Jan to Jun 2026
- €2,101
- Left to pay at the median
- €601
SEAI's fixed grant for a semi-d or end of terrace at the standard rate is €1,500. SEAI's median cost for attic insulation on a semi-d or end of terrace from January to June 2026 was €2,101. €2,101 less €1,500 leaves about €601. Our sum; your quote can be higher or lower.
Send this for a real priceHow this is worked out
The grant is SEAI's fixed amount for that home type and rate, as Citizens Information lists it. The median cost is SEAI's own figure from grant-funded attic jobs completed between January and June 2026; the PDF doesn't say whether VAT is in. Left to pay is the median less the grant, our sum. The home must have been built and lived in before 2011, the contractor must be on SEAI's register, and SEAI must approve the grant before work starts. It's an estimate, never a quote.

Tap your home, when it was built, what's in the attic now and who you are. Then leave your number and one SEAI-registered insulation contractor who covers your area rings you to look at the attic and price it in writing.
FAQ
Questions people ask
Why use BER certificates?
Every BER records the roof's U-value. SEAI publishes the full register; we took the 586,283 certificates for houses built before 2011, leaving out BERs done for grant claims so homes just upgraded don't skew it.
Is the grant different by county?
No. SEAI's fixed grants are national.
Why is Dublin lowest?
Only 16% of Dublin's pre-2011 houses show a roof at 0.16, and the median roof U-value is 0.40, the weakest of 26. The register doesn't say why; most Dublin roofs have some insulation, but not enough.
