Double Glazing Grants and Funding in the UK (2026)

Many homeowners ask whether they can get a grant towards double glazing. Help does exist through national energy-efficiency schemes, though windows are often funded as part of a wider package rather than on their own — and eligibility is usually targeted.

Where help can come from

• Government energy-efficiency schemes (which change over time) often prioritise insulation and heating, sometimes including glazing for eligible households.
• Energy supplier obligations can fund measures for lower-income or less energy-efficient homes.
• Local authority schemes vary by area and come and go.

Check what’s current

Because schemes open, close and change rules frequently, always check the latest official guidance — the gov.uk energy efficiency pages and the Energy Saving Trust are the reliable starting points, and they can point you to current grants you may qualify for.

If you’re paying yourself

The biggest saving most people make isn’t a grant — it’s comparing a few local installers for the same specification. Get free quotes and you may be pleasantly surprised.
