Some window replacement grants exist across the UK to help cover your costs, but these are predominantly for vulnerable households or those on low incomes.

Previous government schemes have offered window replacement grants such as the Green Deal and the Green Homes Grant, but they are no longer accepting new applications, and no grants specifically exist for double glazing.

What this means is that you’ll struggle to find window replacement grants if you’re renovating a house or looking to upgrade to double or triple glazing. But households which qualify for the small number of grants available could save significantly on their energy bills. 

Installing A++ rated double glazed windows and replacing single glazing could save homeowners up to £175 a year, according to the Energy Saving Trust.

Take a look at which grants are currently available to see how much funding you could be eligible for. 

Energy Company Obligation 

The Energy Company Obligation, or ECO scheme, puts an obligation on energy companies to help low-income households make heating improvements to their homes. While the scheme isn’t necessarily aimed at providing replacement windows, you may be able to get funding for new windows on the scheme. 

New insulation and boiler replacements are the most common improvements available on the scheme, but providing you’re eligible for ECO funding, an energy supplier will arrange for an installer to come to your home and install the energy-efficiency measures which most benefit your house.

Home Repairs Assistance 

The Home Repairs Assistance grant offers up to £5,000 over three years - depending on the improvements you apply for - to those who meet one of the following criteria:

  • You are 60 years of age or older
  • You are over 18 and receive one of these benefits: Income Based Jobseeker’s Allowance, Income Support, Housing Benefit, Pension Credit, or Working Tax Credit
  • You are over 18 and have a disability or receive Disability Living Allowance, Attendance Allowance, or Long Term Incapacity Benefit

The scheme provides financial cover for small scale home improvements on the inside or outside of a property, including new windows. To apply, find your local council information and check your eligibility. 

Home Improvement Agencies

Some Home improvement Agencies (HIAs) may be able to assist vulnerable homeowners by offering advice and assistance with finding the money for window replacements. Some also offer practical home repairs and smaller building jobs to help vulnerable people live in their home safely. Find your local HIA here.

Care & Repair 

Care & Repair England was a charitable scheme in England that closed in April 2022. If you were aged 60 or older and had broken and damaged windows then the organisation would help to arrange securing you a grant from your local authority. 

Housing Aid for Older People (Ireland only)

This Irish scheme is available to anyone over 66 years of age and living in a home with ‘poor living conditions, such as damaged or broken windows, which affect your quality of life. 

The amount paid to homeowners by the scheme depends on the income received by each household, but you could receive as much as 95% of all total costs or a maximum of £8,000 to be used towards getting new double glazing.
