Quick answer
What does a window fitter do, and what does it cost in the UK?

UK 2026 cost: £350–£600 per uPVC window, £700–£1,200 aluminium, £600–£1,000 timber. Whole-house uPVC for 10 windows runs £3,500–£6,000. FENSA registration is mandatory for selling on.
Window fitter vs handyman vs glazier
| Job | Window fitter | Handyman | Glazier |
|---|---|---|---|
| Replace whole window | ✅ Recommended | ❌ Not legal (FENSA) | ⚠️ Glass-only |
| Replace cracked pane | ✅ Yes | ⚠️ Limited | ✅ Recommended |
| Adjust hinges / replace handle | ✅ Yes | ✅ Yes | ⚠️ Possible |
| Bi-fold doors | ✅ Recommended | ❌ Not legal | ❌ Not glass-only |
| FENSA certificate | ✅ Issued | ❌ No | ❌ No |
Replacement windows are notifiable building work. A FENSA or CERTASS-registered fitter saves you the £200–£400 Building Control fee and issues the certificate at the end.
