People often ask about “free window grants”, so it’s worth being straight about this: standalone grants just for replacement windows are rare. But there are routes to help with home improvements in the right circumstances.
Grants for windows
There’s generally
no dedicated national grant purely for new windows.
Energy-efficiency schemes focus on the measures that save the most energy
first — insulation and heating — though improvements can sometimes form part
of a wider funded package for a very inefficient home. Be sceptical of adverts
promising “free windows for everyone”; they’re usually sales pitches, not
grants.
Help with home improvements
Where a home improvement is about health, safety or disability, more help is available. A Disabled Facilities Grant from your council can pay up to £30,000 in England towards adaptations like ramps, stairlifts or a downstairs bathroom (see families and disability support). Many areas also have a Home Improvement Agency that helps older and disabled residents with repairs and adaptations, and some councils offer their own local assistance.
What to do next
For energy measures, see our home energy grants page; for adaptations, contact your council about a Disabled Facilities Grant. Always use a reputable, certified installer and get more than one quote.
