Does Windscreen Replacement Count as an Insurance Claim?

It’s the question we’re asked more than any other: if I claim for my windscreen, does it count as a claim — and will it cost me my no-claims discount or push my premium up? The short answer is reassuring, but the detail matters and varies by policy. This guide explains, in plain English, how windscreen cover works in the UK, what a glass excess is, whether a windscreen claim affects your no-claims discount, and how to claim the right way.

We handle insurance windscreen claims every day, and we’re approved by major insurers — so this is the explanation we give customers before they pick up the phone. For our service, see the insurance page; to get the work done, windscreen replacement and repair.

Is a windscreen claim treated like a normal insurance claim?

Generally, no — and this is the key point. Most insurers treat glass claims as a separate category from at-fault accident claims. Windscreen cover (often a defined section of a comprehensive policy) usually has its own excess and its own rules, precisely because glass damage is common, no-one’s “fault” in the usual sense, and cheap to deal with if caught early.

So while a windscreen claim is technically still a claim — you should declare it when an insurer asks “have you made any claims in the last five years?” — it typically does not carry the same consequences as a bump or a write-off. The two things drivers actually worry about are the no-claims discount and the next renewal premium, so let’s take those head-on.

Will a windscreen claim affect my no-claims discount?

In most cases, no — a glass-only claim usually does not reduce your no-claims discount (NCD). Insurers commonly ring-fence windscreen and glass claims so they don’t erode the bonus you’ve built up, because the alternative (drivers leaving chips unrepaired to protect their NCD) leads to bigger, more expensive replacements later.

That said, there are two honest caveats. First, it varies by insurer and policy — a minority of policies, or repeated glass claims, can be treated differently, so check your policy wording or ask before you claim. Second, “doesn’t affect your no-claims discount” is not the same as “has no effect on your premium.” Some insurers still record the claim and may factor it into your next quote even when your NCD is untouched. The effect, if any, is usually small compared with an at-fault claim.

“The fear of losing a no-claims bonus stops people fixing chips, and that’s the worst thing they can do. Nine times out of ten a glass claim doesn’t touch your bonus — and a £0 repair today saves a much bigger replacement and a far bigger headache later. Check your policy, but don’t let the worry leave you driving on damaged glass.” — Manish Patel, founder, MyCarGlass

What is a glass excess, and how much is it?

The excess is the part you pay towards a claim. Windscreen cover usually has its own separate excess, distinct from your main accident excess, and it differs between repair and replacement:

For chip repairs, many insurers charge little or no excess — the excess is frequently waived entirely — because repairing a chip is so much cheaper than replacing a whole screen that insurers actively encourage it. For full replacements, there’s typically a fixed glass excess, often somewhere in the region of £75 to £150, though the exact amount is set by your policy and can be higher or lower.

The single most useful thing you can do is check your own policy documents for the glass section — it states your repair and replacement excess in black and white. If you’re not sure, we can often tell you when you give us your insurer’s name and policy details.

Does using an insurer’s “approved repairer” matter?

It can. Many policies pay out in full only when you use an insurer-approved repairer, or they cap what they’ll contribute towards a non-approved one (and you cover the difference). Because we’re approved by major insurers — including Aviva, Allianz, LV=, AXA, NFU and the AA — we can carry out the work under your policy and handle the claim directly, so you typically pay only your glass excess rather than the whole bill up front. See our insurance page for how that works in practice.

Repair or replace — and why it changes the claim

Whether your glass is repaired or replaced changes both the cost and, often, the excess:

A repair keeps your original factory glass, takes around 20–30 minutes, and frequently costs you nothing under insurance. A replacement is needed when damage is too large, too deep, in the driver’s line of sight, or at the edge of the glass — it’s a bigger job, carries the glass excess, and on modern cars adds ADAS camera calibration (which itself should be included so your safety systems work correctly afterwards). We walk through exactly where the line sits in Windscreen chips and cracks: the ultimate guide to repair or replace; for the camera step see ADAS calibration.

The takeaway for your wallet: catching damage while it’s still a repairable chip is usually the cheapest possible outcome — often free, and usually with no impact on your no-claims discount.

Can you drive with a chipped or cracked windscreen?

There’s a legal reason not to leave damage as well as a financial one. Driving with a windscreen that obstructs your view is an offence, and the rules turn on where the damage is and how big it is.

For MOT and roadworthiness, the windscreen is split into zones. Zone A is the 290mm-wide strip directly in front of the driver, centred on the steering wheel — your critical line of sight. Damage here is judged most strictly. The rest of the wiper-swept area (often called Zone B) is assessed more leniently.

The MOT thresholds are clear: any damage larger than 10mm in Zone A fails, as does damage larger than 40mm anywhere else in the swept area. So a chip the size of a 5p in your eyeline can fail an MOT even though the same chip lower down the glass would pass. These sizes aren’t absolute, though — the examiner has discretion, so a chip under 10mm in Zone A can still fail if it obscures your view, and damage over 40mm outside Zone A isn’t an automatic fail in every case.

Beyond the MOT, driving with a windscreen in a dangerous condition can land you with a fixed penalty of 3 penalty points and a fine (commonly a £100 fixed penalty) — and far more if it goes to court, since it’s an offence to use a vehicle in a dangerous condition under section 40A of the Road Traffic Act 1988. The CU20 endorsement code sometimes applied is the general “dangerous condition” code rather than a windscreen-specific one. Your insurance can also be affected if a known defect contributed to a claim.

The practical point ties straight back to repair versus replace: a small chip caught early is usually a quick, often-free repair that keeps you legal. Leave it, let it spread into your eyeline or past those size limits, and you’re into a chargeable replacement and an MOT or penalty risk.

How do I make a windscreen claim, step by step?

1. Check your cover. Confirm your policy includes glass/windscreen cover and note your repair and replacement excess (it’s in the policy schedule).
2. Call an approved repairer. Rather than ringing the insurer first, you can call us — as an approved repairer we can validate cover and lodge the claim with your insurer for you.
3. Pay only your excess. Where the work is covered, you typically pay just the glass excess; we invoice the insurer for the rest.
4. Get the work done — and calibrated. For replacements on camera-equipped cars, make sure ADAS calibration is part of the job.
5. Keep the paperwork. Hold on to the invoice and any calibration certificate for your records.

“Always ask the repairer to confirm what your policy actually says before any work starts — your excess, whether repair is covered, and whether calibration is included. A good firm checks all of that with your insurer up front, so there are no surprises when the job’s done.” — Robert Webster, windscreen expert, MyCarGlass

What does a windscreen repair or replacement actually cost?

To decide between claiming and paying, it helps to know the cash prices — because if the job costs less than your glass excess, claiming makes no sense. As a guide to the current UK market:

A chip repair typically runs around £40 to £120 if you pay directly (typically around £80), and is frequently £0 under insurance because insurers waive the excess to encourage early repair. A standard windscreen replacement on a mainstream car generally falls in the £250 to £450 range, while premium and ADAS-equipped vehicles can run from around £500 well past £1,000–£2,000 once sensors, heating, acoustic glass and calibration are involved. ADAS camera calibration adds roughly £150 to £400 where required (and more on complex systems), and should be quoted as part of the job. Your glass excess, if you claim a replacement, is usually in the £75 to £150 region depending on your policy.

Prices correct as of June 2026 and shown as general market ranges — your exact price depends on your vehicle, glass specification and any calibration needed. For our current figures see our prices and the replacement cost guide, or request a quote.

Should I claim at all, or just pay?

Sometimes paying directly is the sensible choice — for example, if a chip repair costs less than your time spent claiming, or if your replacement excess is close to the out-of-pocket price of the job. Because glass claims usually don’t dent your no-claims discount, the calculation is mostly about excess versus cash price rather than long-term premium damage. For current cash prices see our prices and the replacement cost guide, or request a quote and we’ll tell you both the claim route and the cash route so you can choose.

What causes windscreen chips — and how to cut the risk?

Most chips aren’t bad luck so much as physics. The usual culprit is stone strike — loose grit and stones flung up by the vehicle in front, especially on motorways, gravel and freshly surfaced roads. Temperature shock does the rest: blasting hot air at frozen glass, or pouring warm water over an icy screen, can turn a tiny, stable chip into a spreading crack in seconds. Older, already-stressed glass, potholes and slammed doors all add to it.

You can’t avoid every stone, but you can stack the odds in your favour. Keep your distance behind lorries and gritters so debris loses energy before it reaches you, ease off on rough or newly chipped surfaces, and defrost gently — let the heater warm the cabin rather than shocking the glass. Above all, fix a chip the moment it appears: a fresh chip is repairable and often free, but once it spreads into your line of sight or past the MOT limits, you’re into a full replacement.

The bottom line

A windscreen replacement is a claim in the strict sense — you should declare it when asked — but for most UK drivers it behaves very differently from an accident claim: it usually doesn’t reduce your no-claims discount, it’s governed by a separate (often small or waived) glass excess, and an approved repairer can handle the whole thing so you pay only that excess. The worst move is leaving damage unrepaired out of fear of “making a claim.” That’s how a free chip repair becomes an expensive replacement.
