How to choose between them
A whole-home job in Norwich typically runs £2,700 to £8,200 (local cost factor 0.91×), so the spread between three quotes on the same brief is worth chasing. Medieval and Georgian houses in the walled centre, Victorian terraces across Golden Triangle and Lakenham, plus interwar Eaton Park semis.
Heritage note: The city centre is a large conservation area - listed building density is one of the highest in England outside London.
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.
