How Much Does a Windscreen Replacement Cost? (2026)

In the UK, windscreen replacement typically costs between £150 and £400, but modern vehicles with sensors and advanced driver assistance systems (ADAS) can be more expensive.

A windscreen is a key safety feature in your vehicle, not just a piece of glass. It supports the car’s structure, helps airbags deploy correctly, and protects visibility while driving. 

If it is cracked or badly damaged, replacement is often the only safe option. Find out more about windscreen replacement costs in 2026 and what to look for below.

How much does a windscreen replacement cost?

The cost of replacing a windscreen usually sits between £150 and £400, but depends on the type of vehicle, glass specification, and whether additional technology such as rain sensors or cameras is fitted.

Higher-end vehicles cost more due to specialist glass, extra labour, and recalibration of sensors after installation. Your mechanic will inform you if these services are required.

The typical costs for windscreen replacements in 2026 are:

Windscreen repair vs replacement?

Not all windscreen damage requires a full replacement. Small chips can often be repaired quickly and cheaply, while larger cracks usually require a full replacement that takes longer and costs more.

Here’s Bumper’s general guidance for windscreen services:

Repair is suitable when:

• The chip is smaller than around 40mm

• Damage is not in the driver’s direct line of sight

• The crack has not spread

Replacement is needed when:

• The crack is large or spreading

• Damage affects the driver’s view

• There are multiple impact points

• The glass structure is weakened

As a rule, repair is a short-term fix, while replacement restores full safety and strength. If you’re in doubt, always get your car checked out by a mechanic.

How much does a windscreen repair cost?

As explained above, repairing a windscreen is much cheaper than replacing it and is often covered by insurance. Small repairs are usually completed in under an hour and prevent further cracking.

Note that: Insurance excess is the amount you may need to pay out of pocket when making a claim, even if your insurer covers the rest of the windscreen repair or replacement.

Here are the typical costs in 2026.

Windscreen chip repair thresholds

Chip repair often means you can get away with not booking a replacement. However, windscreen chips can only be repaired if they are:

• Smaller than around 40mm

• Not located in the driver’s direct view

• Not close to the edge of the windscreen

If the damage spreads beyond this, replacement is usually required, even if there are no other cracks or issues.

How long does windscreen replacement take?

A typical windscreen replacement takes around 4 to 6 hours in total. This includes inspection, removal, fitting, and the adhesive's curing time.

In some cases, vehicles may need to remain stationary longer to allow the sealant to fully set. Mobile services may also require additional time, depending on the weather and access conditions.

What are signs a windscreen needs replacing?

Unsure whether your windscreen needs a makeover? 

Common signs of a replacement include:

• Large or spreading cracks

• Damage directly in the driver’s line of sight

• Multiple chips close together

• Glass distortion or weakening

• Sensor or camera interference in modern vehicles

If you notice any of the above, head to the garage as soon as possible. Windscreen damage can become dangerous for you and others on the road.

Is it illegal to drive with a cracked windscreen?

It is not automatically illegal to drive with a cracked windscreen. However, it becomes illegal if the damage obstructs your view or makes the vehicle unsafe. You should book in for a repair ASAP if this is the case.

Drivers can be fined if the condition is considered dangerous, and serious damage may lead to points or prohibition from driving.

Will a cracked windscreen fail an MOT?

Yes, a cracked windscreen can cause an MOT failure if it affects the driver’s visibility or is located in the swept area of the wipers. Severe damage or obstruction is likely to result in an immediate fail.

Does insurance cover windscreen damage?

Most comprehensive insurance policies include windscreen cover, which is good news if your glass needs a little TLC.

In many cases, insurance means that:

• Repairs are fully covered or cost very little

• Replacements require an excess payment

• Your no claims bonus is usually not affected

Of course, it is important to check your specific policy before booking work. Bumper always recommends reviewing your car insurance policy before repairs.

Can I replace a windscreen myself?

Replacing a windscreen yourself is not recommended unless you have mechanic training and professional equipment.

Window repairs require specialist tools, strong adhesives, and precise fitting. Modern vehicles also need ADAS recalibration after installation, which requires diagnostic equipment.

Incorrect fitting can cause leaks, poor visibility, or serious safety risks. Do not tamper with your car!

Mobile vs garage windscreen replacement

Windscreen replacement can be carried out at a garage or via a mobile technician. However, it’s usually recommended that you book into a garage unless the damage is so severe that you cannot drive. 

The general advice is as follows:

• Mobile fitting is convenient and done at your home or workplace

• Garage replacement may be better for complex or ADAS-equipped vehicles

• Mobile services may be limited by weather or access

ADAS calibration and modern windscreen costs

Many modern vehicles require ADAS recalibration after a windscreen replacement. ADAS stands for Advanced Driver Assistance Systems, which includes safety features that rely on cameras and sensors mounted on or near the windscreen.

These systems are commonly found in newer cars, especially mid-range and premium models, and can include features such as lane-keeping assist, automatic emergency braking, and traffic sign recognition.

Calibration ensures these systems continue to function correctly after the windscreen is replaced. This can add £100 to £300+ to the total cost, depending on the vehicle and system complexity.

Final summary

Windscreen replacement in the UK typically costs between £150 and £400, although modern vehicles with advanced systems can cost more. Repair is cheaper and suitable for small chips, but replacement is necessary when damage is larger or affects safety.

If you notice damage, it is best to get it checked as soon as possible!
