What moves the price
Two homes on the same street rarely pay the same. These are the factors that shift a window quote up or down.
Frame material
uPVC is usually the most affordable, aluminium sits in the middle with slimmer sightlines, and timber commands a premium for its finish and heritage look.
Window size & style
Larger openings, bay configurations and multi-opener designs use more material and labour than a simple fixed or single-casement window.
Glazing specification
Double vs triple glazing, acoustic or toughened glass, and the energy rating you choose all change the per-unit price.
Access & fitting
Upper floors, scaffolding, awkward access and making-good after removal add to the labour portion of any quote.
Number of windows
A whole-house order usually earns a better per-window rate than replacing one or two units on their own.
Region & installer
Labour rates vary across the UK, and each firm prices its overheads differently — which is exactly why comparing quotes pays.
How to compare fairly
A price only means something when it is like-for-like. Here is how to compare window quotes with confidence.
- Compare like-for-like. Match the same material, glazing spec and number of windows across every quote before you judge the price.
- Use vetted, accredited installers. Look for firms registered with schemes such as FENSA or CERTASS so replacement work is certified and building-regulation compliant.
- Check the guarantee. An insurance-backed guarantee and deposit-protection cover mean your money and workmanship are protected if anything goes wrong.
- Treat every figure as a typical range. Real prices are confirmed on a free home survey once the installer has measured up.

How much does a new window cost in the UK?
As a typical guide, a supplied-and-fitted uPVC casement window ranges from around £350 to £650, with aluminium and timber costing more. Your exact price depends on size, glazing and access, and is confirmed on a home survey.
Which window material is cheapest?
uPVC is usually the most affordable option, followed by aluminium, with timber typically the most expensive. Our prices-by-material guide compares them like-for-like.
Are the prices on this site guaranteed?
No. Every figure is a typical range to help you budget. A firm price can only be given after an installer surveys your home and measures the openings.
Is it free to compare quotes?
Yes. Comparing quotes through us is free and no-obligation. You only pay if you choose to go ahead with an installer.
How many quotes should I get?
We suggest comparing at least three like-for-like quotes so you can judge price, specification and guarantee together rather than on cost alone.
