How to choose between them
A whole-home job in St Albans typically runs £3,500 to £10,400 (local cost factor 1.16×), so the spread between three quotes on the same brief is worth chasing. Medieval and Georgian houses around the cathedral and Fishpool Street, Victorian and Edwardian villas in Marshalswick and Marlborough Road, plus interwar semis in Bricket Wood.
Heritage note: Around 20 conservation areas including the Cathedral Quarter and Verulamium.
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.
