Replacing a single uPVC window typically costs £400-£700, a full house of uPVC windows (around 8-10 windows) usually runs £4,000-£8,000, and composite or aluminium front doors commonly cost £900-£2,000 fitted depending on style and glazing.
Price depends on frame material such as uPVC, aluminium or timber, glazing type (double versus triple), window size and style, and whether old frames need removing and disposing of.
Check that installers are FENSA or CERTASS registered, which confirms building regulations compliance, and compare quotes on glazing U-values and warranty length, not just the headline price.
