How to choose between them
A whole-home job in Merthyr Tydfil typically runs £2,600 to £7,700 (local cost factor 0.85×), so the spread between three quotes on the same brief is worth chasing. Iron and coal-industry Victorian terraces (rows of miners' cottages) dominate the town centre and outer valleys, with interwar municipal housing in Gurnos and Galon Uchaf.
Heritage note: Around 6 conservation areas including central Merthyr Tydfil and Cyfarthfa.
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.
