The cost of aluminium windows depends on a variety of factors, including the price of materials, glazing and other options. For example, triple-glazed windows cost more than double-glazed ones, as there is an extra layer of glass. As such, there are no fixed prices for aluminium windows. However, according to the independent trade site Checkatrade, you can expect to pay an average of £475 for most types of aluminium windows and £665 for aluminium sliding windows.
Of course, how much you pay will be affected by the choices you make for your windows, meaning some aluminium windows can be installed at a lower than average price. For example, if you are using a trade windows service, which is the supply only, the costs will be lower than having them fitted too.

What Affects Aluminium Windows Prices?
If you are curious about what affects the prices involved in buying and installing aluminium windows, or even if you simply want to keep costs low for your installation, the following factors will influence how much you pay. Knowing each of these gives you more control over the costs:
- Size is everything: The amount of glass needed for double glazing over a large area is higher, so the price will increase too. You can expect this to happen whether you are installing aluminium or uPVC frames in your available window space. Aluminium windows often have slim frames, so the glass costs can often be even higher than on uPVC frames.
- Colours matter: Aluminium window finishes are not just about double and triple glazing; you can get grey, white and black or white powder-coated aluminium frames, which can easily push the cost of a project higher. Aluminium window frames without powder-coated finishes may be lower, but these are less protected from the weather.
- Composite windows can reduce your costs: Composite windows often use a range of materials, so might simply clad the windows with aluminium and not have the entire frame made of solid metal. Aluminium cladding also helps to reduce the transfer of heat, as metal is a conductor, so composite windows are more efficient.
- Bifold windows have more panels: Sliding windows usually have two panels, while casement windows typically have just one. A bifolding window, on the other hand, can have three or more. More panels, which are necessary to achieve the bifold design, will mean more materials used and therefore higher aluminium window prices.
- Installations have unique challenges: Perhaps you have to comply with challenging Building Regulations, maybe your wall needs repairing, or even just a lot of cleaning and preparation work before installation. Unique circumstances can crop up and greatly influence the cost of your installation.
- Patterns take extra work: It is easy to understand how the cost of triple glazing in a window will be more than that of a double-glazed window. However, certain types of glass, such as privacy glass or frosted glass, are more expensive too. This is because it undergoes a treatment process to make it let light in while making it impossible to see through.
- Casement windows are more secure: A casement window will often have a sturdier locking mechanism because they open outward and the frame supports require more materials to safely hold the weight of the frame while open. The presence of extra materials in casement window designs of any type will affect the overall cost.
- Sliding windows use thicker frames: Larger expenses from additional materials in the case of sliding window mechanisms are another potential factor that could have an impact on your project costs. The weight of the door and the actual sliding mechanism will make it simple to open, but it uses more materials and takes effort to construct moving parts.
Double or triple-glazed aluminium windows are always more expensive than uPVC, but they have a very appealing look and will add to a home’s value. As metals go, aluminium is low-cost. It also offers the same benefits to a home’s noise reduction and energy efficiency.

UPVC vs Aluminium Windows Prices
If you are unsure about how to keep prices as low as possible but still want the installation of your dreams, you might consider getting the same type of window but with a uPVC frame. Many of the criteria that affect aluminium windows prices will remain in uPVC frames. However, as it is a less expensive material, average prices for installations are much lower. According to Checkatrade, the average cost of uPVC windows is somewhere between £250 and £400, with an average cost somewhere between £325 and £475 for aluminium.
