Double Glazing Doors Cost UK
When people search for double glazing doors they usually mean a fully glazed French-door or patio-door replacement rather than a small glazed panel in a front door. The fitted cost depends mostly on door system, width and whether the opening already exists.
Quick price answer: A medium set of uPVC French doors is modelled at £1,267–£2,157, while a medium uPVC sliding patio door is £1,130–£2,054. A project containing one of each is around £2,346–£4,262.
Double-glazed door examples
Complete fitted examples for common replacement openings.
Figures are modelled UK-average fitted-market estimates from the Window Price Calculator engine, using its 24 September 2026 research refresh. They include ordinary removal, standard fitting, basic making good and VAT; scaffolding, hidden structural repairs and highly bespoke work can sit outside the range.
Why the two door systems price differently
Both use insulated glazing, but the frames and hardware work in different ways.
French doors
Two hinged leaves need locks, keeps, hinges and threshold adjustment. They suit narrower traditional openings and give a familiar double-door appearance.
Sliding patio doors
The glazed panels are usually larger, but there are fewer moving leaves. The mechanism can make a medium replacement slightly cheaper than an equivalent French-door set in our model.
Costs that sit outside a normal replacement
These items can push a real quote beyond the modelled range.
