Window layout comparison · 2026
Fixed vs Opening Window Cost
Two windows with the same outer dimensions can cost different amounts because opener hardware and extra sash frames add components and manufacturing time. This is why “price by size” alone cannot fully explain a window quote.
Quick price answer: For a medium uPVC opening, our fixed example is £322–£585, a single-opener example is £357–£649 and a two-opener version is £403–£733.
Same size, different opener layout
The examples use medium standard white uPVC with ordinary double glazing.
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.
How much do openers change the model?
Holding the approximate size constant isolates the layout effect.
| Layout | Centre price | Difference vs fixed |
|---|---|---|
| Fixed | £454 | — |
| 1 opener | £503 | +£49 |
| 2 openers | £568 | +£114 |
Why opening windows cost more
The extra price represents real components and fabrication.
More frame sections
An opening sash has its own profile inside the outer frame, plus gaskets and glazing.
Hardware and adjustment
Hinges, locking gear, handles and workshop adjustment are needed for every opening sash.
