There are no longer any direct SEAI grants for windows and doors in Ireland. Homeowners can receive funding for new windows and doors as part of The National Home Energy Upgrade Scheme. This is designed as part of a larger, retrofit designed to bring homes up to a BER rating of B2 or higher. Additionally, the Better Energy Warmer Homes Scheme also offers grants for windows and doors to those who are considered vulnerable and people who receive qualifying social welfare payments.
While there are no direct SEAI grants available for standalone homeowners in Ireland, the Sustainable Energy Authority of Ireland (SEAI) does offer financial assistance for the upgrading of doors and windows as part of other, larger retrofitting grant schemes.

The National Home Energy Upgrade Scheme, also known as the One-Stop Shop scheme, provides comprehensive SEAI grants to help upgrade the energy efficiency of your home.
These SEAI grants are administered directly by the SEAI, with a private contractor carrying out the work on their behalf.
Under this scheme, you can receive SEAI grants towards the upgrading of your windows and doors to significantly improve your home's heating efficiency as part of a wider, full-home retrofitting upgrade.
This makes it an excellent option for those seeking substantial SEAI grants for windows and doors.
New for 2026: Low-Interest Retrofit Loans
For costs not covered by the grant, homeowners can now access the Home Energy Upgrade Loan Scheme. This offers low-interest loans (approx. 3%) of up to €75,000 for energy upgrades, including windows and doors, provided you are working with an SEAI One-Stop Shop.
The scheme provides specific SEAI grant amounts for doors and windows.
In 2026, you can receive €800 towards the installation of 2 external doors. Any additional doors will not be covered by the scheme.
| Type of Home | Grant Amount |
|---|---|
| Apartment | €1,500 |
| Mid-terrace house | €1,800 |
| Semi-detached or end of terrace house | €3,000 |

To apply for this SEAI grant for windows and doors, you should contact an SEAI registered One-Stop-Shop.
The Better Energy Warmer Homes Scheme offers free replacement windows for vulnerable individuals and people who receive certain welfare benefits.
To qualify for a windows grant via this scheme, you need to meet the following criteria:
Priority is given to the least energy-efficient homes in the country, those built prior to 1993 with a Building Energy Efficiency rating (BER) of E or lower.
Replacement windows are typically only covered by this scheme if your walls are also insulated at the same time and your existing windows are single-glazed.
Once measurement is complete and manufacturing begins, it takes about four to five weeks for the installation to take place.
This scheme requires obligated parties (energy suppliers with sales greater than 600 GWh per year) to provide support to homeowners for energy efficiency projects, such as certain home improvements.
Under this scheme, you may be able to get a grant for full window and external door replacements. These are not direct SEAI grants but are enabled by the SEAI's framework.
To apply, it’s best to first contact your own energy supplier to see if they will offer support. The following domestic energy suppliers are considered obligated parties in 2026:
How Much Can New Windows Save on Energy Costs?
Replacing old single-pane windows with new energy-efficient ones (Double or Triple Glazing) could reduce your energy bills by €100 to €400 per year. Furthermore, Budget 2026 maintains 0% VAT on the installation of these energy-efficient windows, providing an immediate upfront saving.
SEAI isn’t the only provider for home upgrades. The Housing Aid for Older People Scheme is aimed at elderly people (over 65) living in poor housing conditions.
Works covered by this scheme include the repair or replacement of windows and doors.
