Find a local window and door fitter
Replacement windows are covered by building regulations, so the installer should either be FENSA/Certass registered or the work notified to building control. That certificate matters when you sell.

Window and door fitters FAQs
How much do new windows cost?
A typical uPVC casement window is £550–£900 supplied and fitted in 2026; a full house of 8–10 windows commonly falls between £5,000 and £9,000.
Can just the glass be replaced?
Yes — if frames are sound, replacing a misted sealed unit costs a fraction of a new window, often £80–£200 per unit.
Do I need a FENSA certificate?
Replacement windows in England and Wales must comply with building regulations. A registered installer self-certifies and issues a certificate you'll need when selling.
