Funding availability

Three ways to fund your new windows and doors

Help 2 Buy Windows double glazing grant

Qualifying applicants have new windows and doors installed with no cost incurred. The scheme was set up to help those in need improve their energy efficiency and lower their bills through high-efficiency double glazing.

Grants are administered subject to qualifying criteria and the funding available to the scheme.

About the grant

Window & door funding

If you do not qualify for the grant, UK installation companies working with the scheme offer funding options that spread the cost of new windows and doors, many with no deposit required. Your needs are assessed case by case.

Funding for this option is provided by our installation partners, not Help 2 Buy Windows.
