SEAI 2026 Grant
Up to €5,600 off your new windows and doors
The new SEAI Windows & Doors Grant opened for applications on 2 March 2026. Grant amounts vary by property type — detached homes can claim the full €5,600. Here’s how it works, who qualifies, and how Wright Windows gets you grant-ready.
What changed in 2026
A standalone grant for windows and doors — for the first time.
Before March 2026, you could only get an SEAI window or door grant as part of a full One Stop Shop retrofit package — usually only worth doing if you were also insulating, installing a heat pump, or doing solar. For most homeowners with a single fabric problem — draughty windows, a tired front door — it didn’t make sense.
That changed on 2 March 2026. The Better Energy Homes scheme now includes a standalone Windows & Doors grant: up to €4,000 toward new windows (depending on your property type) and a flat €800 per external door, capped at two doors. The grant is applied for individually, without needing to bundle in other upgrades. For households on certain Social Protection payments, supports are higher again.
The catch — and there is one — is that SEAI wants ‘fabric-first’ assurance: the rest of your house has to be insulated to a reasonable standard before they’ll pay you to glaze it. That’s the rule most homeowners get confused about. Below is the simple version.
Grant amounts by property type
How much you can claim depends on your home.
The windows grant tiers by property type. The doors grant is flat at €800 per external door, up to a maximum of two doors (€1,600), regardless of property type.
| Property Type | Windows Grant | Doors Grant | Maximum Total |
|---|---|---|---|
| Detached | Up to €4,000 | Up to €1,600 | €5,600 |
| Semi-detached / End-of-terrace | Up to €3,000 | Up to €1,600 | €4,600 |
| Mid-terrace | Up to €1,800 | Up to €1,600 | €3,400 |
| Apartment / Duplex | Up to €1,500 | Up to €1,600 | €3,100 |
Eligibility
Do you qualify? Three quick checks.
You need to pass all three of these checks to claim the new Windows & Doors grant. Wright Windows handles the U-value side automatically — the first two depend on your property.
Built before 2011 — and your own home
Your home must have been built and lived in on or before 31 December 2010, and must be owner-occupied as your primary residence. Newer homes are assumed to already meet modern fabric standards; rental properties and second homes aren’t eligible.
Walls and roof already up to scratch
You must meet one of the following:
- Heat Loss Indicator (HLI) of 2.3 W/K·m² or lower after install, or
- BER Advisory Report rates your walls and roof ‘Good’ or ‘Very Good’
Check 3 — Window performance
Every Wright window beats the SEAI threshold.
SEAI requires that new windows installed under the grant have a U-value of 1.4 W/m²K or better. That’s the heat-loss number — lower is better. Our entire NSAI-certified range comes in below that threshold, most of it well below.
There’s a second technical requirement worth knowing: under the SEAI scheme, north-facing windows must be triple-glazed. Windows on other elevations can be double-glazed as a minimum. Wright Windows fits triple-glazed units across the entire range at no premium where the application requires it.
| Wright Windows Range | NSAI U-value | SEAI Eligible? |
|---|---|---|
| Eco Wright Passive uPVC | 0.7 W/m²K | ✓ Yes |
| R9 Legacy composite flush sash | 0.8 W/m²K | ✓ Yes |
| Aluminium casement & tilt-and-turn | 0.8 W/m²K | ✓ Yes |
| Aluclad windows | 0.8 W/m²K | ✓ Yes |
| Standard uPVC range | 1.0–1.2 W/m²K | ✓ Yes |
| SEAI requirement | 1.4 W/m²K maximum | — |
Two routes to the grant
Apply yourself, or let a One Stop Shop manage it.
The grant amount is the same either way. The difference is how you handle paperwork and cash flow.
Route 1
Individual Energy Upgrade Grant
You apply directly via the SEAI Better Energy Homes online portal before the work starts, pay your installer in full when the work is done, then claim the grant back once your post-works BER is registered.
Best for homeowners who can fund the project upfront and want to deal with SEAI themselves.
- Apply online before work begins
- Use an SEAI-registered contractor (we are one)
- Pay in full, claim back after BER
- Money lands in your account in 4–6 weeks
Route 2
One Stop Shop service
An SEAI-registered One Stop Shop provider manages the whole project for you — survey, BER, application, install, post-BER — and deducts the grant upfront from your bill so you never lay out the full amount.
Best for homeowners bundling windows with insulation, heat pump or solar upgrades on the same job.
- One contractor handles everything
- Grant comes off the invoice upfront
- Suits multi-measure deep retrofits
- We work with several One Stop Shops — ask us
Step-by-step
How a Wright Windows SEAI project runs.
-
Free site survey & written quote
We come to your home, measure every opening, photograph the existing reveal details, and come back with a written quote on Wright Windows letterhead within one working day.
-
Confirm fabric eligibility
If you already have a post-July-2021 BER showing your HLI or wall/roof ratings, we can confirm eligibility from that. If not, we’ll point you to an SEAI assessor for a pre-works BER — this is the only step we don’t do in-house.
-
Apply via Better Energy Homes (online)
You log in to hgs.seai.ie, register an application, list Wright Windows as your contractor (registration ref supplied with your quote), and SEAI issues a grant offer.
-
We manufacture and install
Lead time on most products is 6–10 weeks from order. Site installation typically takes 1–3 days depending on opening count. We handle disposal of the old units and snag any reveal making-good.
-
Post-works BER & grant claim
Once installed, your assessor returns to issue an updated BER. You log back into the SEAI portal, upload the BER plus our certificate of compliance and our invoice, and SEAI lodges the grant to your account in 4–6 weeks.
Common questions
SEAI Windows & Doors Grant FAQ
Can I claim the grant if I’m only replacing a few windows?
No — this is a ‘whole house’ upgrade grant. You need to replace all the poorly-performing windows in the house. Any windows you’ve replaced in the last ten years can usually be retained, provided you can supply the original Declaration of Performance showing they meet the 1.4 U-value standard.
I have a 2008 build — do I qualify automatically?
Houses built 2005–2010 often meet the ‘Good’ wall and roof requirement by default because the building regulations of that period required reasonable fabric insulation. You’ll still need an SEAI-registered assessor to confirm via your BER Advisory Report, but it’s a much shorter path than for an older home.
What if my BER is from before July 2021?
Older BER reports don’t display the Heat Loss Indicator or wall/roof rating that SEAI now needs to see. The data still exists in SEAI’s back-end — an assessor can request it, or you can have a fresh BER done. Most assessors offer a combined pre-and-post BER package specifically for grant claims.
Can I apply for the windows grant and the heat pump grant together?
Yes — and you’ll often want to. The heat pump grant (now up to €12,500) requires a Heat Loss Indicator of 2.3 W/K·m² or lower. Upgrading old draughty windows is often what takes a home over that line. The two grants are claimed separately but the underlying BER work is shared.
Do I need to use an SEAI-registered contractor?
Yes. Only contractors on SEAI’s registered list can be named on the grant application. Wright Windows is an SEAI-registered contractor for the Windows & Doors measure — we’ll provide our registration reference with every grant-route quote.
How long does the grant payment take?
If you’re going the individual-grant route, the typical timeline is 4–6 weeks from uploading your post-works BER to the grant landing in your bank account. The One Stop Shop route deducts the grant from your invoice at the time of install, so you never wait.
What about the doors grant — does it apply to back doors too?
Yes — the doors grant pays €800 per external door, capped at two doors (a maximum of €1,600). It covers front, back and patio doors so long as each meets the same fabric-first eligibility checks and a U-value of 1.4 W/m²K or better. Our composite doors and Spitfire aluminium range comfortably exceed this.
I’m a landlord — can I claim the grant for my rental?
No. The standalone Windows & Doors grant under Better Energy Homes is only available for owner-occupied primary residences. Rental properties, holiday homes and second homes are not eligible under this individual grant route. Landlords can sometimes access support via separate retrofit schemes — talk to an SEAI-registered One Stop Shop provider about options.
Do north-facing windows have to be triple-glazed?
Yes. Under the SEAI scheme, any new window facing north must be supplied as triple-glazed. Windows on south, east and west elevations need to be at least double-glazed, but can be triple-glazed if you prefer. We fit triple-glazed units across our entire range, so this isn’t a problem.
I already ordered windows before the portal opened — have I missed out?
Probably not. The scheme was officially announced on 27 January 2026, and any window or door work ordered after that date can still apply for the grant retrospectively, even though the SEAI portal didn’t open until 2 March. If your order is from 27 January onward, talk to us — we can help you assemble the paperwork to claim it back.
What does Wright Windows charge for the grant paperwork?
Nothing. We provide our SEAI contractor reference, the Declaration of Performance for every product, and our installation certificate at no extra charge as part of any grant-route quote. The only third-party costs you’ll see are the BER assessor’s fees (typically €200–€400 for the pre-and-post BER).
