Cost to replace a car window by type
The price you pay will largely depend on which window needs replacing and how complex the installation is.
Car windscreen replacement cost
Replacing a car windscreen usually sits between £250 and £1,000, with an average price of around £625.
Costs are typically higher for windscreens because they may include:
Rain or light sensors
Heating elements
Advanced driver assistance systems (ADAS)
Specialist glass or tinting
If these features are present, the system may need recalibrating after installation, which can add time and cost to the job.
Car rear window replacement cost
Rear window replacement often falls in the range of £150 and £350, with an average price of around £250.
Rear windows often include:
Heating or defrost elements
Integrated aerials
Wiper mechanisms
These components can make replacement slightly more complex than a standard side window.
Car side window replacement cost
Replacing a driver or passenger window typically costs between £80 and £350, with an average price of around £215.
Side windows are usually the quickest and simplest to replace, especially if the glass is standard and the window mechanism hasn’t been damaged.
However, if the door mechanism or seals are affected, additional repairs may be needed.

Additional costs to budget for
The headline replacement price usually covers the basic job, but some situations can involve extra costs.
Here are some of the extras you may need to budget for:
ADAS (Advanced Driver Assistance Systems) calibration after windscreen replacement
Repairs to damaged window mechanisms
Replacement seals or fittings
Mobile call-out fees
Disposal of old glass
Emergency or out-of-hours service
Not every job will include these extras, but it’s worth checking before work begins so you can compare quotes accurately.
What should be included in a car window replacement quote?
A clear quote should explain exactly what’s included in the price and what isn’t — helping you understand exactly what you're paying for.
Check for:
Replacement glass supply
Labour and installation
Removal and disposal of old glass
Any calibration required
VAT, if applicable
Expected completion time
Warranty or guarantee details
If one quote looks much cheaper than the others, check what’s missing. It may not include calibration, disposal or specialist glass.
How long does car window replacement take?
In most cases, replacing a car window is a relatively quick job — it can usually be completed in around 1 hour.
Additional time may be needed for:
Calibration of sensors or cameras
Waiting for adhesive to set
Sourcing specialist glass

Can you claim car window replacement on insurance?
If your vehicle insurance policy includes glass cover, you can usually make a claim for repairs or replacements. However, you may have to pay an excess.
Can you replace a car window yourself?
Technically, it’s possible to replace some car windows yourself, but in practice, it’s rarely recommended.
Modern vehicles often rely on precise glass fitting, specialist adhesives, calibrated sensors, and safety compliance.
Mistakes can lead to leaks, poor visibility or system faults, which can be expensive to fix later.
For most drivers, using an experienced automotive glazier is the safest and most reliable option.

When should you arrange car window replacement?
It’s worth arranging replacement as soon as you experience any of the following:
Cracks spreading across the glass
Shattered or missing windows
Poor visibility through the windscreen
Water or wind entering your vehicle
Problems with window mechanisms
Early repairs are usually quicker and cheaper than waiting until the damage worsens.
