How to choose between them
A whole-home job in Northampton typically runs £2,800 to £8,300 (local cost factor 0.92×), so the spread between three quotes on the same brief is worth chasing. Victorian shoe-worker terraces in Semilong and St James, Edwardian villas in Abington and Kingsley, plus large postwar estates on the edges.
Heritage note: Around 22 conservation areas including Boot and Shoe Quarter and Abington.
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.
