Before you contact a Barnet installer
A full double glazing job in Barnet typically lands between £3,400 and £10,400 (local cost factor 1.15×), depending on opening count and spec. Around 15 conservation areas - Hampstead Garden Suburb is one of the most rigorously protected in England, with prescribed window designs.
- Check the company is current and not in liquidation on the Companies House register.
- Confirm FENSA or CERTASS registration on the relevant scheme's own "find an installer" search - membership is per-company and can lapse.
- Get the quote in writing, itemised per window or door, and check the guarantee is insurance-backed.
- Ask for two recent installs you can look at - around Finchley, Hendon, Edgware or your own street.
