A Practical, Cost-Saving Guide for Homeowners in Ireland
Energy costs continue to rise across Ireland, and homeowners are looking for smart, long-term solutions to reduce bills while improving comfort. The Sustainable Energy Authority of Ireland (SEAI) has introduced a revamped Windows and Doors Grant launching in March 2026, offering significant financial support to make energy-efficient upgrades more accessible than ever.
If you’re planning to upgrade your windows or doors, this grant could save you thousands.
Why Windows and Doors Matter for Energy Efficiency
Older windows and doors are one of the biggest sources of heat loss in Irish homes. Industry data shows that 20–30% of a home’s heat can escape through inefficient glazing and frames.
Upgrading to modern, energy-efficient double or triple-glazed units can:
-
Reduce heat loss dramatically
-
Lower energy bills
-
Eliminate drafts
-
Improve indoor comfort
-
Increase property value
-
Reduce carbon emissions
SEAI’s 2026 grant ensures these benefits are financially achievable for many homeowners.
Who Is Eligible for the SEAI Grant?
The Windows and Doors Grant is available to:
-
Homeowners
-
Landlords
-
Charities
-
Approved Housing Bodies
-
Companies and Management Companies
-
Holiday Home Owners
Basic Eligibility Requirements:
-
The property must have a valid MPRN (Meter Point Reference Number).
-
The home must have been built and occupied before 2011.
-
Works must be completed by an SEAI-registered contractor.
-
A post-works BER (Building Energy Rating) assessment is required.
Grant Amounts – How Much Can You Claim?
SEAI provides fixed grant amounts based on property type — not on the cost of works.
Windows Grant
| Property Type | Grant Amount |
|---|---|
| Apartment | €1,500 |
| Mid-Terrace House | €1,800 |
| Semi-Detached / End-of-Terrace | €3,000 |

€5,600 total grant support
This makes the 2026 scheme one of the most generous targeted retrofit supports in Ireland.
Technical Requirements You Must Meet
To ensure genuine energy improvements, SEAI has set strict technical standards:
-
New windows must achieve a U-value of 1.4 W/m²K or better.
-
After the upgrade, the home must meet a Heat Loss Indicator (HLI) of 2.3 W/K·m² or better — or demonstrate that attic and wall insulation are rated “Good” or “Very Good.”
-
A post-installation BER assessment must confirm the improvements.
These requirements ensure the grant supports real energy efficiency improvements — not cosmetic upgrades.

The grant officially opens Monday, 2nd March 2026.
