How to choose between them
A whole-home job in Southend-on-Sea typically runs £2,900 to £8,800 (local cost factor 0.98×), so the spread between three quotes on the same brief is worth chasing. Seaside Victorian and Edwardian villas along the seafront and Prittlewell, interwar semis in Westcliff and Leigh, plus 1930s-40s bungalow estates common on the Essex coast.
Heritage note: Around 18 conservation areas including Old Leigh and Clifftown.
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.
