How to choose between them
A whole-home job in Southampton typically runs £3,200 to £9,500 (local cost factor 1.05×), so the spread between three quotes on the same brief is worth chasing. Victorian terraces in Portswood and Bevois Valley, interwar semis in Highfield and Bassett, plus dockside modern developments post-2005.
Heritage note: Around 15 conservation areas including Old Town and Bassett Green.
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.
