What Affects the Cost of Premium Glazing
Two homes with the same number of windows can end up on very different invoices. Here is what genuinely moves the price, and what does not.
How Much Do Aluminium Windows Cost?
Aluminium windows typically cost £1,400–£2,600 per window supplied and installed. Here is what moves you up or down that range.

Aluminium is the frame material most homeowners ask about when they want slim sightlines, a long service life and a contemporary or heritage look depending on the profile chosen. It sits above timber-look uPVC in price, largely because of the material itself and the more sophisticated hardware typically fitted, but for many homes it is worth the difference.
As a guide range, expect £1,400–£2,600 per window supplied and installed, with the final figure depending heavily on size, opening type, glazing specification and finish. This guide breaks that range down so you can budget sensibly before a survey.
The baseline range
- Typical guide price
- £1,400–£2,600 per window, supplied and installed
- Includes
- Frame, glazing, standard hardware, installation, making good
- Excludes typically
- Structural alterations, scaffolding, bespoke colours
A single, modest-sized fixed or single-opening aluminium window sits toward the lower end of that range. A large, multi-light casement with several opening sections, upgraded hardware and a non-standard colour sits toward the top, and bespoke or oversized units can exceed it.
What moves the price within the range
| Factor | Effect on price |
|---|---|
| Size | Larger frames use more material and glass, cost scales with area |
| Number of opening lights | Each hinge, handle and lock adds cost over a fixed pane |
| Glazing specification | Triple glazing, acoustic or solar control glass each add a premium |
| Colour | Standard colours are cheaper than dual-colour or woodgrain finishes |
| Hardware | Upgraded handle finishes cost more than standard powder-coated options |
| Access | Upper floor or restricted access can require scaffolding |
Why aluminium costs more than timber-look uPVC
Aluminium frames use narrower sightlines and a thermally broken core to achieve their slim profile, which requires more sophisticated engineering than a uPVC frame. The hardware specified with aluminium systems, from multi-point locking to handle finishes, also tends to be a higher tier. The result is a window that generally lasts longer and looks sharper, at a higher starting price than timber-look uPVC, which typically runs £950–£1,700 per window.
Budgeting for a whole project
For a typical house with ten to fifteen windows, an all-aluminium specification at these guide prices puts a realistic budget somewhere between £14,000 and £39,000 before any structural work, though most homes with a mix of sizes and standard specification land closer to the middle of that span. Mixing aluminium on principal or street-facing elevations with timber-look uPVC elsewhere is a common way to manage budget without compromising the front of the house.
- Get a full-house survey rather than pricing window by window in isolation
- Decide early which elevations matter most for aesthetics and specify accordingly
- Ask whether standardising sizes across the house reduces manufacturing cost
- Confirm what is included: making good, disposal of old frames, and certification

Double vs Triple Glazing Costs
Triple glazing typically adds roughly 10–20% over an equivalent high-performance double-glazed unit. Whether it is worth it depends on the elevation, the room and your priorities.

Aluminium vs uPVC Windows
Aluminium and modern timber-look uPVC are both good materials. The right choice depends on the age and style of your house, your budget, and how the frames will be used, not on which one is fashionable.
