How much do new windows cost?

To budget for replacing your old windows, it's important to research how much new windows cost as many factors contribute to the price.

What is the average price for new windows, is a question we get asked all the time and if you want a short answer - the average price for new windows is anything between £500 to £3,200 per window*, depending on options.

As a long answer, please read our guide below to find out how much new windows cost.

Don't compare cheap new window costs online

To work out how much new windows cost you need to consider several variables:

  • Style of the frame
  • Size of the frame
  • Material used for the frame
  • Double or triple glazed?
  • Number of windows
  • Will you need scaffolding?
  • Do you need planning permission?
  • The cost of installation

The cost of a new window listed on a website might seem cheap at first, but installation costs can leap up if you need to erect scaffolding to reach high windows.

Or, a few months after installation, you find a problem and must re-install the window at your own expense because the installer doesn't have a warranty.

And, poor quality uPVC can warp - so it's a false economy and not a long-term investment when you have to factor in the early replacement of your windows.

If you want to compare the cost of new windows like-for-like, you need a full quote that factors in all requirements to see who really offers the best value.

Why don't you show the average price for new windows on your website?

The second most popular question we get asked is, why don't you show prices on your website? The reason for this is because all our windows are bespoke made to precision fit your specific requirements.

We have well over 77 different style options that you can choose from to make the perfect window you want. As you can imagine, it's pretty difficult to try and add a list of prices that covers all of those options because we don't do average.

How do other companies show the average price for new windows on their website?

You can buy windows off-the-shelf that are made to specific sizes in limited colours and materials. But, these windows are a standard size and don't take into account all the problems that can arise when fitting new windows:

  • Many houses have windows that are not a standard size
  • Frames are not straight due to building shifts
  • You might want windows to open a certain way
  • Or, want handles that are easier to reach
  • Listed properties have limitations on style or colour

Cheaper off-the-shelf windows are often not a perfect fit and to make up for this an installer will use excessive expanding foam around the edges to fill in the gaps.

This is not only ugly but can also cause damp, draughts and shorten the life of your windows - in the long run, it's a false economy.

With thousands of options to choose from, our windows are designed to meet your needs.

Beware of installers that give a new windows cost before they see your property.

Just like a decorator, plumber or builder needs to see your property before he can give you a price, a reputable window installer will need to see your home before they can give an accurate cost of windows.

Beware of cheap double glazing

If something looks too good to be true, then it usually is. And when it comes to anything for your home, never take the cheapest option as it will end up more expensive in the long-term.

More importantly, it can devalue your property for resale. A cheap new window cost is not going to offer guarantees of longevity or quality of materials.

Poor quality windows leave you at risk from:

  • Scratches on new frames and glass
  • Cheap uPVC can warp over time
  • Incorrect frame sizes that need excessive expanding foam to force fit
  • Bad installation that causes damp, leaks or draughts
  • Double glazing desiccant - where the double glazing seal fails and bits get in-between the glass
  • Condensation between the glass from poor seals
  • Fading on the frames
  • Generally, a poor aesthetic that quickly looks shabby

What should your cost of windows quote include?

When researching the average price for new windows from different suppliers make sure that you compare like-for-like.

Keep in mind that prices listed on a website don't reflect the full cost of windows and all the variables.

Ask your supplier to provide a full and transparent quote that lists everything that's included from the new windows cost to installation and any aftercare and warranties they offer.

You don't want to have the surprise of any hidden costs when you're half-way through a window installation.

What to look for from your cost of windows quote:

  • A full technical survey of your property
  • The sizes, styles and colours of the frames
  • The materials to be used
  • Type of glass to be used
  • The window energy rating for the glass
  • Window furniture and handles
  • External window cills
  • Full installation including all fixings, trims and sealants
  • Disposal of your old windows

Most importantly, make sure you get a certificate to say your installer is registered with a competent person scheme, such as FENSA or Certass. This means that you have automatic approval for building regulations and don't need to apply yourself.
