Windscreen Replacement FAQ

1. How much does windscreen replacement cost in the UK?

UK Car Glass, one of the few fitters that publishes prices, lists £299 to £450 for a basic windscreen without ADAS and £450 to £1,200+ for a car with a windscreen camera, calibration included. It says most drivers pay £400 to £600; its average over 244 jobs in July to September 2026 was £491.06. Its dearest listed car is the Jaguar I-Pace at £1,354.

2. How much does windscreen chip repair cost?

Published single-chip prices at the UK chains run from £50 (Halfords) through £78 (UK Car Glass) to £90 (National Windscreens, a starting price). Autoglass quoted £225.98 to drivers without glass cover (checked October 2026). On glass cover you pay the chip excess instead: Aviva Signature £10, Swinton £25, AvivaPlus Premium nothing.

3. Does car insurance cover windscreen replacement?

Most comprehensive policies include glass cover, though Aviva notes some basic comprehensive products do not. You pay the glass excess: Aviva Signature £115 for a replacement and £10 for a chip, Swinton £125 and £25 through its approved repairer. Third-party-only policies do not include windscreen cover. Aviva says most insurers won't affect your No Claim Discount for a windscreen claim.

4. Will a cracked windscreen fail an MOT?

A chip larger than 10mm in Zone A (the 290mm strip directly in front of the driver within the swept area) will fail. In Zone B (the rest of the swept area), damage larger than 40mm will fail. Damage outside the swept area is not tested. A properly repaired chip can pass an MOT.

5. What is ADAS calibration and do I need it?

ADAS (Advanced Driver Assistance Systems) calibration resets the forward-facing camera behind your windscreen after replacement. If your car has lane departure warning, auto emergency braking, or adaptive cruise control, calibration is required. UK Car Glass puts calibration at £150 to £400 and includes it in its replacement price; Elite Garages lists calibration from £190 plus VAT.

6. How long does windscreen replacement take?

UK Car Glass says fitting takes 60 to 90 minutes on a standard car, the car must then stay put for at least 30 minutes (Safe Drive-Away Time), and most of its customers drive away within 2 hours of the technician arriving. A camera car needing calibration takes longer.

7. Can I drive straight after windscreen replacement?

No. You must wait for the Safe Drive-Away Time the fitter gives you; UK Car Glass says at least 30 minutes. During this period the adhesive bonds the glass to the body. Driving too soon can let the windscreen shift or the seal fail, so follow the fitter's aftercare advice.

8. Is Autoglass more expensive than other fitters?

On the one cash price it publishes, yes: Autoglass quoted £225.98 for a chip repair without glass cover, against £50 at Halfords, £78 at UK Car Glass and from £90 at National Windscreens. Autoglass and National Windscreens quote replacement by registration and publish no list, so get more than one quote. On an insurance job you pay your glass excess whichever approved fitter does it.

9. What is the difference between OEM and aftermarket glass?

OEM (Original Equipment Manufacturer) glass is made by the same supplier as the factory original. It matches exactly in thickness, tint, and acoustic properties. Aftermarket (OEE) glass is made by third parties to the same BS safety standards but may differ in acoustic performance. No UK chain publishes the price gap, so ask each quote which glass it is for. For standard cars, aftermarket is fine. For luxury cars with acoustic glass, OEM is worth the extra cost.

10. Does a heated windscreen cost more to replace?

Yes. UK Car Glass puts a heated windscreen at £80 to £150 more than the plain equivalent. Its published prices for cars whose typical spec includes a heated screen run from £375 (Ford Focus 2005-2011) to £1,354 (Jaguar I-Pace).

11. Will claiming for a windscreen affect my no-claims bonus?

Usually not. Aviva says most insurers won't affect your No Claim Discount for a windscreen claim, and Swinton says windscreen claims through it do not count towards your No Claims Bonus. Aviva adds that you should tell a new insurer about a windscreen claim, and that some insurers may raise your premium, so check your own policy wording.

12. Can a chipped windscreen be repaired?

Usually. UK Car Glass repairs chips up to about 25mm (a one-pound coin) and cracks up to 75mm outside Zone A; damage within 7cm of the edge usually needs replacement. A technician injects clear resin, cures it with UV light, and polishes the surface, which stops the chip spreading.

13. How long does a windscreen chip repair last?

A properly done chip repair is permanent in most cases. The resin fills the damage, restores structural integrity, and prevents the chip from spreading. The repair will be visible on close inspection but will not deteriorate over time. If the chip was repaired early (before water ingress or temperature damage), the result is very stable.

14. Do I need to recalibrate ADAS after a chip repair?

No. ADAS recalibration is only needed when the windscreen is removed and replaced. A chip repair does not disturb the glass or the camera mounting, so no recalibration is required. This is one of the many reasons to repair chips before they become cracks that need full replacement.

15. How do I find the cheapest windscreen replacement near me?

Get at least three quotes: one from a national chain (National Windscreens or Auto Windscreens), one from an independent fitter (use myWindscreen.co.uk or Checkatrade), and compare with your insurer's approved repairer. Check whether ADAS calibration is included. Choose aftermarket glass unless you have a luxury car with acoustic windscreen.
