How to choose between them
A whole-home job in Barnet typically runs £3,400 to £10,400 (local cost factor 1.15×), so the spread between three quotes on the same brief is worth chasing. Interwar semis dominate Finchley, Hendon and Edgware, Georgian pockets in Hampstead Garden Suburb, Victorian streets in East Finchley, plus modern developments in Colindale.
Heritage note: Around 15 conservation areas - Hampstead Garden Suburb is one of the most rigorously protected in England, with prescribed window designs.
Whichever company you approach: get three written, itemised quotes, confirm FENSA or CERTASS registration on the scheme's own register, check the guarantee is insurance-backed, and ask for two recent local installs you can look at. Our guide to comparing double glazing quotes walks through it.
