If you’ve come across a used car with a cracked, chipped, or even missing windscreen, you might be wondering: is it worth buying? A damaged windscreen isn’t always a dealbreaker, but it can come with legal, safety, and financial implications — and it’s something that should never be overlooked.
In this guide, we’ll walk you through what to look out for, how it can affect your rights and responsibilities, and how to ensure you’re getting a fair deal.

Where You Might Encounter Windscreen Damage
You’ll find damaged windscreens crop up in a few common places:
• Private Sales – A seller might offer a lower price due to a chip or crack. But remember: once you’ve bought it, it’s yours. There’s little recourse with a private sale, so always inspect carefully and use any damage as a negotiation point.
• Dealerships – A reputable dealer is unlikely to sell a car with a windscreen that would fail an MOT. However, if there’s minor damage, they may offer to fix it or reduce the price slightly. Dealership cars come with more consumer protection than private sales.
• Car Auctions & Salvage – Auctioned or salvaged vehicles are typically sold “as seen”. If the windscreen is badly damaged or completely smashed, you’ll need to factor in the full cost of repair or replacement before it’s roadworthy.

Types of Windscreen Damage
Not all windscreen damage is created equal. Here’s a quick breakdown:
• Stone Chips – Small chips caused by loose debris. If less than 10mm and not in the driver’s direct line of sight, they can often be repaired quickly.
• Cracks – Longer damage that may run across the glass. Cracks tend to worsen over time and usually mean the windscreen needs to be replaced.
• Scratches – These may look minor but can interfere with visibility, especially in bright sunlight or at night.
• Smashed or Missing Windscreen – A broken or absent windscreen makes the car unroadworthy and is an immediate MOT failure.

Legal & MOT Implications
In the UK, a vehicle must have a clear and unobstructed view of the road to be considered roadworthy. According to GOV.UK guidelines, a car will fail its MOT if:
• There’s damage over 10mm in the area directly in front of the driver (known as Zone A), or
• There’s damage over 40mm elsewhere on the windscreen.
Driving with a damaged windscreen that restricts your view isn’t just an MOT issue — it can also lead to penalty points and fines for using a vehicle in a dangerous condition. You can read more about this at GOV.UK - MOT inspection manual.

Insurance Considerations
Most comprehensive car insurance policies in the UK include windscreen cover, allowing for chip repairs or full replacements with a small excess. However, it’s important to note:
• Pre-existing damage may not be covered. If the damage occurred before you insured the vehicle, the insurer may decline to pay for it.
• Windscreen claims often don’t affect your no-claims discount, but always check the terms of your policy.
If you’re buying a car with existing damage, it’s best not to assume your insurer will cover it — get a quote for the repair or replacement separately.

Windscreen Repair & Replacement Costs
Prices can vary depending on the type of vehicle and the complexity of the glass (for example, cars with rain sensors or built-in cameras). As a rough guide:
• Chip repair: £60–£120
• Full replacement: £200–£500 or more
• ADAS recalibration (if your car has safety systems like lane assist): often an additional £100–£200

Using Damage to Negotiate Price
Windscreen damage gives you some negotiation power when buying:
• Get a repair quote in advance and use that as leverage when discussing price.
• Ask the seller to fix it before sale, or deduct the cost from the final price.
• Avoid relying on insurance to fix it, especially if you’re unsure when the damage occurred — insurers may not cover historical issues.
Being informed about the cost and potential safety implications will help you negotiate confidently.

Things to Check Before Buying
Here are a few simple checks that can save you a lot of trouble:
✔ Inspect the windscreen carefully from both inside and outside the car
✔ Look for MOT advisories related to windscreen damage
✔ Check for ADAS features (like cameras or sensors) that may require recalibration
✔ Ask about the age and history of any damage or attempted repairs
✔ Get a second opinion or professional assessment if unsure

Final Thoughts
A damaged windscreen doesn’t necessarily mean you should walk away from a used car — but it does mean you need to go in with your eyes open. Whether it’s a small chip or a full-on crack, there are safety, legal, and financial implications to consider.
If you’re buying a car with windscreen damage, make sure you know what it will cost to put it right — and use that knowledge to negotiate the best possible deal.
