A damaged windscreen might seem minor at first, but even a small chip can quickly develop into a huge crack, compromising visibility and safety. Whether caused by flying stones, extreme temperatures, or general wear and tear, knowing when and how to replace your windscreen, as well as how much it might cost, can save you money and stress in the long run.
This guide breaks down everything you need to know about windscreen replacement costs in the UK, the types of damage that lead to replacements, repair options, and whether it’s possible to carry out the work yourself.
Understanding the type of damage on your windscreen is the first step in determining whether a repair or full replacement is necessary.
The most frequent form of damage, chips are usually caused by stones or gravel hitting against the glass. Though typically small, they can expand over time, especially if exposed to temperature fluctuations or pressure. This makes them a ticking time bomb if left ignored.
These begin as a central chip with small cracks radiating outwards, forming a star-like pattern.
Edge cracks start within 2 inches of the perimeter of the windscreen and can grow to around 10 to 12 inches long. Due to their position, they require a full glass replacement because the crack poses structural risks.
Similar in size to edge cracks, floater cracks appear away from the edges, often in the centre. Their location can affect visibility and they usually require a replacement.
Caused by rapid temperature changes, such as using hot water to de-ice a frozen windscreen. These cracks often form near the edge of the glass pane and can quickly worsen without impact damage.
Minor damage doesn’t always mean a full replacement is required. Chips smaller than a 10p coin, or cracks less than a few inches, might be repairable, especially if they’re not in the driver’s line of sight. In these cases, affordable stone chip repair kits may offer a temporary solution to prevent the damage from spreading.
However, a replacement becomes necessary in the following cases:
Failing to replace a severely damaged windscreen will not only impair your visibility but may also result in a failed MOT or even fines, as UK law requires a clear, unobstructed field of vision for the driver.

The cost of a replacement windscreen in the UK varies depending on several key factors:
Premium vehicles like Mercedes, Jaguar, or Range Rover cars tend to have more expensive windscreens due to integrated features or custom sizes.
Modern windscreens often include rain sensors, acoustic insulation, cameras, heating elements, or heads-up display technology – all of which raise the price.
Prices fluctuate between providers. A budget replacement for an older car might cost around £200, whereas a high-end, sensor-fitted windscreen could exceed £1,000.
If you have comprehensive car insurance, windscreen cover may be included either as part of the standard coverage or as an optional extra. Typically, you'll only need to pay an excess of £50–£100, depending on your policy. Always check the terms of your policy as some insurers may only cover repairs, while others require the work to be carried out by an approved repair centre.

If you're confident with tools and have some experience with car maintenance, a DIY replacement may seem like a cost-saving option. This can work for older vehicles or cars with simple windscreen assemblies. However, you’ll need to do the following:
Additionally, make sure that the rubber gasket or seal is intact or replaced if necessary. A poor seal can lead to water leaks and wind noise, and even compromise airbag deployment during a collision.

Keep in mind that any mistake – like cracking the new glass or failing to secure it properly – could make the car unsafe to drive and void your insurance cover. Not to mention the fact that removing and installing the glass is a delicate operation that requires more than one person.
| Aspect | DIY replacement | Professional replacement |
| Cost | Cheaper up front | Higher but often covered by insurance |
| Tools needed | Glass, removal tools, adhesive, seals | Included in service |
| Skill level | High (risk of error) | Expert technicians |
| Warranty | None or limited | Often provided |
| Time | Several hours | 30 mins to 2 hours |
While DIY repairs are appealing to some, a professional installation is often faster, safer, and backed by a guarantee of some kind. If your car features advanced driver assistance systems (ADAS), a professional recalibration may be required after the windscreen replacement – something that is best left to the experts.
Whether it’s a star-shaped chip or a long crack creeping across the glass, dealing with windscreen damage swiftly is essential for your safety and compliance with UK driving laws. While minor chips may be handled using a DIY kit, significant or obstructive damage should be professionally assessed and repaired where needed.
Always weigh the potential savings of DIY against the risks and costs of a botched job, particularly if you drive a newer vehicle with complex windscreen technology. Don’t forget to double check your insurance policy.
A: Most professional replacements take between 30 minutes and 2 hours, depending on the vehicle and sensor recalibration requirements.
A: No, you should wait at least a few hours to allow the adhesive to cure properly and ensure the windscreen is safely secured.
A: Yes, but only if it’s outside the driver’s field of view and smaller than 10mm. Larger or poorly positioned chips can fail an MOT.
