See how much composite windows cost so you can set a realistic budget.

How much do composite windows cost?

Factors affecting the cost of composite windows

The cost of composite windows can vary hugely, depending on lots of different factors.

Here are the main ones to consider.

Size

The larger your windows, the more they’ll typically cost. This is because they’ll require more materials and labour.

Type of composite

Composite window frames can be made from several different materials, but the most common are timber-aluminium, uPVC-aluminium and fibreglass.

Each has its own pros and cons. Generally, fibreglass composite windows will cost the most, followed by timber-aluminium composites. uPVC-aluminium composites are generally the least expensive.

Style of window

Whether you go for composite, aluminium, uPVC or timber windows, you’ll have a range of window styles to choose from. Some will cost more than others.

As a general guide, bay windows and sash windows are at the higher end of the price scale. Meanwhile, casement and tilt-and-turn windows will be more cost-effective.

Glazing

Composite double glazing is standard, but you can also choose to upgrade to options such as triple glazing or laminated glass.

Although these upgrades will increase your overall composite window costs, they could improve your energy efficiency and therefore could lower your heating bills in the long run. You could also benefit from reduced noise and increased security.

Customisations

If you choose to customise your composite windows, this will add to your overall costs.

For instance, are you keen to get your windows in a bespoke colour? Or with a specific hardware finish?

Installation

If installing your windows is particularly challenging, your window fitting costs will rise.

For instance, sometimes structural alterations are needed to install a new window – you may need to replace a lintel or reinforce a wall.

The best way to get an accurate estimate for your project is to get quotes from window fitters near you.

We always recommend getting at least three quotes. This way, you can get a feel for a range of companies and check that you’re getting a fair and competitive price for the work.
