Are there window replacement grants in Northern Ireland?
Not as a standalone scheme, and any site promising a dedicated NI window grant is overselling. But replacement windows CAN be funded as part of a wider energy-efficiency package under the means-tested schemes, where new glazing improves a hard-to-heat home, and the incoming whole-house Warm Healthy Homes Fund makes that more likely from 2027, not less.
The straight answer first: there is no standalone window replacement grant in Northern Ireland in 2026. If a website or a doorstep caller tells you otherwise, they are either overselling a broader scheme or selling something worse. That said, "no standalone grant" is not the same as "no funded windows", and the difference matters if your home is hard to heat.
Replacement windows and doors can be funded as part of a wider package under the means-tested energy schemes, principally the NIHE-run Affordable Warmth Scheme, where an assessment judges that new glazing would improve the energy efficiency of a poorly performing home. The window is funded as an energy measure within a bigger job, not as a cosmetic upgrade on its own, and eligibility is means-tested (usefully, disability benefits such as PIP and DLA are not counted in the income test).
The direction of travel helps too. The £150 million Warm Healthy Homes Fund, expected from April 2027, takes a whole-house, fabric-first approach for low-income households, and whole-house logic is exactly where poor glazing gets addressed alongside insulation rather than ignored. If you are eligible and your windows are part of why your home is cold, the successor scheme is more likely to fund them, not less.
If you do not qualify for the means-tested routes, the job is still worth pricing properly rather than waiting: our windows and doors cost guide shows fair NI prices per window and whole-house for 2026, and remember the NI-specific rule that FENSA self-certification does not operate here, replacement windows go through council Building Control, so make sure whoever quotes you accounts for that sign-off.
