How Much Do New Windows Cost?
Replacing your windows is a valuable investment that can improve comfort, energy efficiency and appearance. Unlike generic off-the-shelf products, all windows supplied by Milton Windows are made-to-measure — meaning the price varies based on size, style, materials, glazing and installation needs.
Since each project is bespoke, exact prices are best obtained through a free on-site survey and quote. However, the following guidance can help you plan your budget.
Typical Price Range for New Windows
As a general guide, new windows including supply and installation usually fall within a broad range depending on the configuration you choose:
Standard uPVC casement window: Typical lower-budget option with straightforward operation.
Tilt & turn windows: Popular modern style, usually costing more than basic casements.
Sash windows: Traditional style often higher in cost due to design complexity.
Bay windows: Larger, multi-panel configurations that attract a premium price.
Aluminium or timber frames: These materials usually cost more than uPVC because of their performance and aesthetic properties.

Most Affordable Options
The most budget-friendly choice is typically a white uPVC casement window, ideal for standard openings and offering reasonable performance for everyday needs.
This option tends to fall at the lower end of the cost spectrum, making it a sensible starting point for many homeowners working within a tighter budget.
Window Style
Casement windows: Generally, the most economical basic choice.
Tilt & turn: Slightly higher due to complex hardware.
Sash windows: Traditionally around 25–50% more expensive than basic casement windows.
Bay windows: Can cost 1.5× or more than a standard window due to size and complexity.

Frame Material
uPVC: Often the most cost-effective option.
Aluminium: Around 25% more than uPVC for the same style, reflecting strength and modern design.
Timber: Typically about 50% more than uPVC, often chosen for heritage properties.
Higher-end finishes, colours and glazing types can also add to the overall price.
What Affects Final Price
The ultimate cost of your windows depends on a combination of factors, including:
- Size and shape of the window openings
- Number of windows being replaced
- Glazing type (double vs triple)
- Frame colour and finish
- Hardware and security upgrades
- Installation complexity and access requirements
Because of this variation, most reputable installers (including Milton Windows) emphasise personalised quotes based on a site visit rather than pre-set price lists.
