As of January 27, 2026, the SEAI has introduced new standalone grants for windows and doors. While homeowners previously had to complete a full "One-Stop Shop" retrofit to get this funding, they can now apply for windows and doors as individual measures. Additionally, the Better Energy Warmer Homes Scheme continues to offer fully funded upgrades to those receiving qualifying social welfare payments.
Following a major policy shift in early 2026, the Sustainable Energy Authority of Ireland (SEAI) now offers four distinct pathways for upgrading windows and doors:

This is the most significant update for 2026. The online portal for standalone window and door applications opens on March 2, 2026. This allows homeowners to upgrade their glazing without committing to a full B2 deep retrofit.
Technical Requirement: The HLI Rule
To qualify for the standalone grant, your home must meet a Heat Loss Indicator (HLI) of 2.3 or lower. This ensures the "fabric" of the home (walls and attic) is already sufficiently insulated before the SEAI provides funding for windows.
The grant amounts for 2026 are scaled based on your home type. You can receive up to €800 per external door (for a maximum of 2 doors).
| Type of Home | Window Grant | Door Grant (Max 2) |
|---|---|---|
| Apartment | €1,500 | €800 per door |
| Mid-terrace house | €1,800 | €800 per door |
| Semi-detached or end of terrace | €3,000 | €800 per door |
| Detached house | €4,000 | €800 per door |

The National Home Energy Upgrade Scheme remains the best option for a complete "One-Stop Shop" service. Under this scheme, an SEAI-registered company manages the entire process, from the initial assessment to the final grant application.
New for 2026: Low-Interest Retrofit Loans
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, when working with a One-Stop Shop.
The Better Energy Warmer Homes Scheme offers free replacement windows for vulnerable individuals.
Under this scheme, energy suppliers with sales greater than 600 GWh per year are obligated to support energy efficiency projects. You may be able to secure support for windows and doors through your supplier. Obligated parties include:
How Much Can New Windows Save?
Upgrading to energy-efficient glazing could reduce energy bills by €100 to €400 per year. Budget 2026 also maintains 0% VAT on the installation of these windows.
The Housing Aid for Older People Scheme (for those over 65) covers the repair or replacement of windows and doors.
| Household Income | % Covered | Max Grant |
|---|---|---|
| Up to €37,500 | 100% | €10,700 |
| €37,501 - €43,750 | 85% | €9,095 |
| €43,751 - €50,000 | 75% | €8,025 |
| €50,001 - €62,500 | 50% | €5,350 |
| €62,501 - €75,000 | 30% | €3,210 |
The SEAI online portal for standalone individual window and door grants opens on March 2, 2026. However, works ordered since January 27, 2026, are eligible.
Pensioners may qualify for the Housing Aid for Older People Scheme, which provides up to €10,700 for essential repairs and replacements.
