# Double Glazing Funding

> Double Glazing Funding (www.doubleglazingfunding.co.uk) helps UK homeowners access grants, funding and incentives for new double glazed windows and doors. Operated by H2B Windows LTD (T/A Double Glazing Funding), Saxon House, Hellesdon Park Road, Norwich, Norfolk, NR6 5DR. Phone 0330 808 1074. It works in partnership with the Help 2 Buy Windows scheme (help2buyscheme.co.uk).

## Key facts
- The Help 2 Buy Windows grant is NOT a UK government scheme. It is funded 100% by Help 2 Buy Windows through the sale of leads to its clients.
- Grants are subject to qualifying criteria and available funding; not all applicants qualify.
- Typical qualifying basics: you own your home and your windows/doors are five years old or older. The funding checker gives the current criteria.
- Homeowners who do not qualify for the grant can be offered funding through vetted installation partners (often no deposit) or the Best 4 Less direct-from-manufacturer price guarantee.
- The company behind the site, H2B Windows LTD, also operates Help 2 Buy Windows, a fully accredited national double glazing installer service with thousands of verified Trustpilot reviews.
