How to choose between them
A whole-home job in Cardiff typically runs £2,600 to £7,900 (local cost factor 0.88×), so the spread between three quotes on the same brief is worth chasing. Cardiff's signature bay-fronted Victorian terraces dominate Cathays, Roath and Grangetown, with detached Edwardian villas in Cyncoed and Lisvane, and modern apartments in the Bay redevelopment.
Heritage note: Around 27 conservation areas including Pontcanna, Roath Park and Cathays Park.
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.
