Front bay windows are structural, not decorative - which is what separates a proper £2,800 bay replacement from a £1,200 quote that ends in cracked plaster and a sagging bay roof six months later. The bay frame carries load from the wall above (often a two-storey bay carrying a bedroom and a small pitched roof) and any replacement has to preserve or replace that structural role. Three or five panel bays on 1930s semis are by far the most common configuration in UK housing stock, and where most of the price variation lives.

A like-for-like three-panel UPVC bay on a typical semi runs £1,600-£2,400 fitted, including a new structural bay pole (a steel or aluminium column disguised inside the frame corners that carries the load the old timber bay carried), fresh cills, and reinstatement of internal plaster and external render bands. A five-panel splayed bay on a bigger Edwardian semi is £2,800-£3,800. If the existing bay roof is tiled or leaded and needs stripping and re-covering, add £600-£1,400 for that trade separately.
