Whether it’s thanks to a heavy storm, or a rogue cricket ball, many homeowners find themselves faced with the task of replacing damaged window glass. From cracked glass and severe scratches to a steamed up pane of double-glazed glass, there are a number of factors that will affect the prices you pay for window glass replacement.
This guide offers information about the costs for the replacement of a single window pane, like for like. As opposed to replacing whole window units including frame, or costs to replace an entire set of windows.
Here are the average costs for window glass replacement in the UK. We’ve included prices for both hiring a professional to carry out the work and costs of a single pane of glass, if you’re planning to do the job yourself.
There are a number of reasons that might lead to you having to replace a pane of glass in your window.
The cost of window glass replacement will firstly depend on the style of your window. Some of the most popular types of window are:
These are one the most common types of window found in UK homes, as they’re one of the most versatile options on the market – available in a variety of sizes, materials and finishes.
These windows are most commonly found on Georgian and Victorian homes. They often feature vertically sliding panes of glass that use a weighted system, which can add a cost to the replacement if the weight needs to be adjusted.
One of the more modern options, tilt and turn windows open inwards into the room making them easier to clean and maintain. They also allow you to control how wide they open, so they’re ideal for homes with young children.
These are windows that protrude out from the external wall of a home and create a bay area within the room. They’re a popular choice with UK homeowners for both their style and the ability to add space to a room.

In addition to the type of window you have, the price you pay for window glass replacement will also be affected by the type of glass you choose.
In general, window glass in the UK comes at a high quality standard in terms of energy efficiency and safety. Therefore, standard glass should meet most of your basic needs in terms of avoiding draughts, condensation and energy loss. It’s also the cheapest option for window glass replacement, making it ideal if you’re trying to keep costs low.
Many homeowners choose laminated glass to provide an extra level of safety. Its protective layer of vinyl between the two pieces of glass gives it added benefits including break-in protection (glass cutters don’t work on laminated glass), sound reduction, and improved impact and shatter resistance.
Toughened glass is five times stronger than laminated glass of the same thickness, with a much higher resistance to breaking. Consequently using it for the replacement of your window pane will cost more than standard or laminated glass.
If you decide to hire a professional tradesperson to replace your window glass, you’ll need to factor in the cost of labour. An average cost for a window expert to supply and replace a single glazed pane of glass is around £110, or £120 for a double-glazed window.
One thing to consider when replacing window glass is whether it might be better to replace the whole window unit. While the price will be more than just the replacement glass for your window, sometimes it’s the better option if:
You can keep costs of window glass replacement down by replacing the broken window glass yourself. However, if your windows are under warranty, we recommend contacting the manufacturer first before replacing the glass as you could unintentionally void the warranty.
