UPVC Window UK lists 21,044 active window and glazing companies across 57 UK counties, so homeowners can see who is registered near them and get free quotes for installations, repairs and replacements.
Where the listings come from
Every company on this site is an active business on the UK Companies House register whose recorded trade (SIC) code is joinery installation (windows and doors). We group each company by the town and county of its registered office address. We refresh the dataset from the monthly Companies House bulk export.
A listing is a public record. It is not a recommendation, a review, or a statement that the company is currently trading or FENSA or Certass registered. Always confirm an installer's FENSA or Certass registration on the official register before any window installation work begins.
How the quote service works
When you complete the Get Free Quotes form, we pass your job details to FENSA or Certass registered installers covering your postcode. They contact you directly with quotes. There is no charge and no obligation.
Corrections & removals
Company data originates from Companies House. If you want a listing corrected or suppressed, tell us through the enquiry form and we will action it.
