How to choose between them
A whole-home job in Harlow typically runs £3,000 to £9,000, so the spread between three quotes on the same brief is worth chasing. Designated a postwar New Town in 1947, Harlow is largely 1950s-70s brick semis and low-rise estates around Old Harlow and the town centre, with a distinctly Frederick Gibberd master plan.
Heritage note: Around 8 conservation areas mostly in Old Harlow village.
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.
