How much does uPVC double glazing cost?

It’s really hard to say accurately how much double glazed windows cost. Prices depend on several factors, including:

  • Window size
  • Frame material
  • Your location

For example, a large window with a more expensive frame material, like wood, will cost more than a small uPVC window. The same window will also cost more in an expensive area of the UK, like London, compared to a cheaper area, like Newcastle.

However, we know how important it is to have a rough idea of how much your window project could cost. This will help you decide how many windows to buy, and which frame material to go for.

How much does wooden or aluminium double glazing cost?

If you don’t fancy uPVC frames, you could go for wooden or aluminium windows. These materials are popular because people often think they look better than uPVC.

For example, wooden frames can look great on period properties, while aluminium frames can really suit more modern, glazed structures.

These frames are usually more expensive than uPVC frames. Wooden and aluminium double glazing costs are typically 30-50% more than uPVC. So, it’s important to bear this in mind when you’re considering frame materials.

3 other things that can affect your double glazed Window price

Once you’ve decided on your frame material, there are still a few other things that can affect how much double glazed windows will cost:

1. Energy rating

Lots of windows have an energy efficiency rating that tells you how good they are at insulating your property. The rating scale runs from A++ (most efficient) to E (least efficient), and is run by the British Fenestration Rating Council (BFRC).

More efficient double glazing is usually more expensive, but it’s often worth the investment. According to the Energy Saving Trust, replacing all the single glazed windows in a detached property with A++ double glazing could save you up to £120 a year on your energy bills. This is compared to C-rated double glazing, which will only save you £100 a year.  

2. Glass type

Glass type can also affect double glazed window costs. For most windows you just need standard glass, but in some rooms of your home you might want obscured glass.

There are also some places where it’s a good idea, or you’re legally required, to use toughened glass. For example, if you have any windows that are close to the ground, these might need to contain toughened glass for safety reasons. The more specialised your glass is, the more it’ll cost.

3. Handles

The type of handles you choose can also affect how much you end up paying. Typically uPVC handles are cheapest, while metal window hardware is more expensive. Weigh up the benefit of having custom handles versus the cost to help you decide.
