How much more do coloured uPVC windows cost than white?
Coloured uPVC windows usually cost about 10–20% more than standard white frames because the coloured finishes require additional manufacturing processes and are produced in lower volumes.
The exact price difference varies between manufacturers and window styles, so it's always worth comparing quotes if you're deciding between white and coloured frames.
If you're replacing all the windows in your home, even a modest increase per window can have a noticeable impact on the total project cost.
Replacing around 10–12 windows in a typical three-bedroom home could cost around £7,500 for standard uPVC, compared with around £8,250 for coloured frames.

What affects coloured uPVC window costs?
Several factors influence the final price.
Window style: Sliding sash, bay and shaped windows generally cost more than standard casement windows
Window size: Larger windows require more materials and glazing
Frame colour and finish: Standard stocked colours are usually less expensive than bespoke finishes
Number of windows: Replacing several windows together can reduce the average installation cost per window
Glazing specification: Triple glazing, acoustic glazing and specialist glass all increase costs
Labour rates: Installation costs vary depending on where you live in the UK
Access: Upper-floor windows or difficult access may increase labour costs
For bespoke RAL colours, expect to pay at the top of the range or above. Most major manufacturers offer at least 10 standard colours across their ranges; RAL custom colours are available but are made to order with longer lead times.

Additional costs
Depending on your project, you may also need to budget for a few extra costs, such as:
Removal and disposal of your existing windows
Repairs to damaged window openings or surrounding brickwork
Scaffolding for upper-storey installations
Upgraded glazing, such as triple glazing or acoustic glass
Trickle vents or other upgrades needed to meet current building regulations
Bespoke colours or made-to-order finishes

How long do coloured uPVC windows last?
Coloured uPVC window frames typically last 20–35 years with routine maintenance.
Most manufacturers also provide a warranty for the coloured finish, although the length of cover varies between products.
Do coloured uPVC windows fade?
Modern coloured uPVC windows are designed to retain their appearance for many years.
Manufacturers use UV-resistant pigments and protective finishes to reduce fading caused by sunlight and weather exposure. As with any external finish, darker colours exposed to strong sunlight for long periods may show signs of ageing sooner than lighter shades.
When comparing products, check the manufacturer's warranty for the colour finish.
