How to choose between them
A whole-home job in Dover 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. Georgian and Victorian townhouses around the seafront and Castle Hill, terraced streets in the Old Town, plus interwar and postwar semis in Buckland and River.
Heritage note: Around 15 conservation areas including central Dover and St Margaret's.
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.
