How to choose between them
A whole-home job in Bangor typically runs £2,600 to £7,700 (local cost factor 0.85×), so the spread between three quotes on the same brief is worth chasing. Victorian slate-quarry terraces along Upper Bangor, Georgian townhouses around the cathedral, plus interwar and postwar university-adjacent semis.
Heritage note: Around 5 conservation areas including Bangor Cathedral Precinct and Upper Bangor.
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.
