How to choose between them
A whole-home job in Westminster typically runs £3,800 to £11,300 (local cost factor 1.25×), so the spread between three quotes on the same brief is worth chasing. Georgian squares (Belgravia, Mayfair), Regency terraces around Pimlico and Marylebone, Edwardian mansion blocks in Marylebone and Bayswater, plus modern glass-fronted apartments around Victoria and Nine Elms.
Heritage note: Westminster has 55 conservation areas and thousands of listed buildings - almost any street-facing frame change needs council consent, and works in Belgravia or Mayfair require the tightest specifications.
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.
