uPVC window cost estimates
uPVC is the UK’s most popular window frame for good reason: it is durable, low-maintenance and usually the most affordable option for the same opening. As a typical uPVC window cost guide, expect a supplied-and-fitted casement in the region of £300–£520 each, with the exact figure set by size, glazing and colour.
Typical uPVC ranges
| uPVC window type | Typical supply & fit |
|---|---|
| Small casement (e.g. landing) | £300–£380 |
| Standard casement | £350–£520 |
| Large living-room window | £450–£700 |
| uPVC sash (vertical slider) | £700–£1,100 |
These are typical ranges, not fixed prices. A survey confirms the real figure for your home, allowing for exact sizes and the condition of the existing sills and reveals.
Why uPVC is usually cheaper
uPVC frames are manufactured in high volume and are quick to fit, which keeps both the material and labour shares of a quote down. Aluminium sits higher for its slim sightlines and strength, while timber commands a premium for its appearance and the maintenance it needs over time. If budget is the priority, uPVC almost always gives the most window for the money.

- Glazing: upgrading from double to triple glazing, or adding acoustic glass, raises the unit price.
- Colour: anthracite grey, woodgrain foils and dual colours cost more than standard white.
- Style: flush casements and sash designs sit above the plain casement baseline.
- Energy rating: higher window energy ratings can mean a better glass and spacer specification.
