SEAI windows and doors grant
Not eligible
windowgrants.ie is not SEAI or a government body and does not award grants.
SEAI's windows and doors grant is only for homes built and occupied before 2011.
You can still get a price. If you are 66 or over, your council's Housing Aid for Older People grant can cover windows and doors.
Sent. One contractor will ring you.
Keep your phone close and answer numbers you don't recognise for the next few days. Look up your BER with your MPRN before they ring, if you can.
Add more detail (optional)
It helps the contractor price the job before they ring. Tap what you know and skip the rest.

The catch
The heat loss test comes first
Before SEAI pays for windows, your home has to hold its heat reasonably well already. Your BER advisory report must show Good or Very Good heat loss: an HLI of 2.3 or lower, or roof and walls already rated Good (seai.ie).
If the attic or walls aren't insulated, that may need doing first. SEAI says a previous SEAI attic or wall insulation grant counts towards it (SEAI, 20 Feb 2026). How to check your BER.
Until March 2026, SEAI only funded windows as part of a whole-home upgrade through a One Stop Shop. Since 2 March 2026 you can apply for windows only, doors only, or both. Over 66? Your council's grant can also help: see window grants for over 66s.
Before you agree
What a window grant quote should include
Use this list when the contractor rings. Each line is something you can ask to see in writing.
- Every window and door listed, with its size and style
- The U-value of each window: 1.4 W/m²K or better for the grant
- Removal of the old frames, making good inside and out, and sills
- Doors priced separately, so the door grant is clear
- Confirmation the contractor is SEAI-registered
- A written price with VAT stated

FAQ
Questions people ask
How much is the SEAI window grant?
SEAI pays €4,000 for a detached house, €3,000 for a semi-D or end of terrace, €1,800 for a mid-terrace and €1,500 for an apartment, plus €800 per external door for up to two doors (seai.ie, checked 28 October 2026).
Who qualifies?
Homes built and occupied before 2011, with an MPRN, replacing single or older double glazing, with a BER showing Good or Very Good heat loss, and an SEAI-registered contractor.
What is the heat loss test?
Your BER advisory report must show Good or Very Good heat loss. That means a Heat Loss Indicator of 2.3 or lower, or a home whose roof and walls are already rated Good (seai.ie). If your home doesn't meet it, upgrade the insulation first and then apply.
Can I get it for doors only?
Yes. Windows only, doors only, or both.
Who will ring me?
We pass your request to one SEAI-registered contractor who covers your area. They ring you, look at the windows and give you a price. Nothing is booked until you say yes. You or a One Stop Shop deal with SEAI on the grant.
Is this site SEAI?
No. windowgrants.ie is not SEAI or a government body and does not award grants.
