How to choose between them
A whole-home job in Swansea typically runs £2,600 to £7,700 (local cost factor 0.86×), so the spread between three quotes on the same brief is worth chasing. Terraced streets across Sandfields and Uplands, interwar semis in Sketty and Killay, plus coastal 1960s-70s stock along the Mumbles road.
Heritage note: Around 30 conservation areas across Swansea Bay including Uplands and Mumbles.
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.
