SEAI Grant Amounts by Home Type — Ireland 2026

Almost everyone who phones us about the SEAI windows and doors grant opens with the same question: “How much will I actually get?” The honest answer is that it depends entirely on your home type — and a lot of people quote the headline €5,600 figure when their semi-detached only qualifies for €4,600. Here are the exact 2026 amounts, what each home type really gets, and — the part nobody else shows you — what you pay after the grant using our real fitted prices.

How much is the SEAI windows and doors grant by home type?

The SEAI window grant pays €1,500 to €4,000 depending on your home type, plus €800 per external door (maximum two), for a combined maximum of €5,600 on a detached home (SEAI.ie, 2026). You can apply for the windows grant, the doors grant, or both on a single application.

The door grant is the same flat €800 per door for every home type — only the window grant scales. So a mid-terrace and a detached home both get €1,600 for two doors, but the detached home gets €2,200 more towards windows. Not sure which category you fall into? Our 5-minute eligibility check walks through it.

Is the SEAI grant a fixed amount or a percentage?

It's a fixed amount, not a percentage of your spend — the single biggest misunderstanding we correct on surveys. You receive the full grant for your home type (say €3,000 windows on a semi) provided your fitted cost is at least that much, which it almost always is.

Owen's note: people often assume a bigger job means a bigger grant. It doesn't. Whether you spend €6,000 or €9,000 on windows for a detached home, the window grant is €4,000 either way. That's actually good news — it means the grant covers a larger share of a modest job. The only way to claim more is to add doors (up to two) to the same application.

What will I actually pay after the grant?

Here's what no other grant page shows you: the net cost. The table below pairs the official grant with our real fitted prices (uPVC windows from €600, composite doors from €1,800) so you can see the actual out-of-pocket figure for a typical full-house upgrade. All figures exclude VAT and are illustrative — your exact quote follows a free survey.

For per-unit prices, see our uPVC window prices and composite door prices. The grant typically covers 40–60% of a mid-terrace or apartment job and a smaller but still substantial share of a larger detached upgrade.

How is the grant calculated and paid?

Under the Better Energy Homes scheme, the grant is fixed by home type, then paid after the work is done and a post-works BER confirms the upgrade. The BER assessment costs roughly €150–€300, and SEAI contributes a €50 grant towards it. SEAI then transfers the money directly into your bank account — an inspection may apply on a sample of homes.

Crucially, you apply yourself before any work begins, and you must wait for the formal grant offer before starting — commencing early forfeits the grant. The full sequence is in our step-by-step application guide. If you'd rather not manage it, a One Stop Shop can apply on your behalf and deduct the grant upfront, though that route usually carries a project-management margin.

Do I qualify for these amounts?

To claim any of these amounts your home must have been built and occupied before 2011, already have good attic and wall insulation (rated “Good” or “Very Good” on your BER Advisory Report), and you must be replacing inefficient existing windows or doors with A-rated units at a U-value of 1.4 W/m²K or better, fitted by an SEAI-registered contractor.

There's one condition many installer pages skip: after the works, your home must hit a Heat Loss Indicator (HLI) of 2.3 W/K·m² or lower, or have attic and walls rated “Good”/“Very Good”. That's why insulation matters before windows. Run our 5-minute eligibility check to confirm where you stand.

Can landlords and holiday-home owners claim too?

Yes — the grant isn't limited to owner-occupiers. SEAI lists eligible applicants as homeowners, landlords, holiday-home owners, companies and owner-management companies, Approved Housing Bodies and registered charities. The same home-type amounts and the pre-2011 build rule apply, and the grant is paid to the property owner. Landlords may also claim a separate Revenue tax deduction of up to €10,000 on retrofit costs against rental income. We fit grant-eligible windows and doors across South West Dublin, Wicklow and Kildare for owner-occupiers and landlords alike.
