Windscreen Replacement

A damaged windscreen is both unsafe and illegal. Driving with chips or cracks larger than MOT limits — 10 mm in your direct line of sight (Zone A), or 40 mm elsewhere — is an automatic fail and a roadworthiness offence.

Even small damage spreads quickly due to road vibrations and temperature swings. Prompt replacement prevents a minor chip becoming a full crack, keeps your vehicle road-legal, and protects the integrity of modern safety systems like lane-keep assist and emergency braking.

Every windscreen replacement is arranged through UK Car Glass and carried out by IMI-certified specialists in our network, trained to BS AU 242b:2022 standards. Our network includes vetted professionals with extensive automotive glass experience.

Replacements typically use factory-spec, UK-approved glass from tier-1 manufacturers — Pilkington, AGC, and Saint-Gobain — the same makers that supply car factories. The only difference from dealership glass is the logo, not the features of the glass; the safety and optical performance are identical.

Most replacements are completed within 1–3 days, and next-day fitting is often possible. Book before 4pm (3pm Friday, 11:30am Saturday) and you can choose the next day as your earliest date. We then confirm your fitting date based on glass availability and your location. For complex ADAS calibrations or unsuitable weather, we arrange workshop fitting through our partner network of 80+ workshops nationwide with covered facilities and specialist equipment.

Modern windscreens often include specialist features that must be matched and verified during replacement:

Heated Windscreen — fine horizontal wires for demisting (common on Ford, Land Rover, Jaguar, Vauxhall). Rain Sensor — small dark unit behind the mirror for auto wipers (most vehicles from 2010+). Acoustic Glass — premium sound insulation marked in the corner (higher model trims). Sun Stripe — dark tinted band across the top to reduce glare. Heads-Up Display — digital data projected onto the glass (BMW 3 Series, Audi A4, Range Rover Defender, VW Tiguan).

We verify every feature against your VIN before ordering your glass, ensuring the replacement matches your vehicle exactly.

Newer cars rely on windscreen-mounted cameras for lane-keep assist, autonomous emergency braking, adaptive cruise control, and other ADAS functions. When the windscreen is replaced, these systems must be recalibrated to factory alignment.

Even a millimetre of misalignment can cause safety systems to malfunction — lane-keeping may steer incorrectly, emergency braking may fail when needed, and your vehicle may fail its MOT. ADAS recalibration is included in the price you're quoted, with no separate charge.

We use two calibration methods depending on your vehicle:

Static Calibration (workshop, using precision targets — common on VW, Toyota, Audi, Mercedes)

Dynamic Calibration (controlled road drive for self-calibrating systems).

Technicians in our network determine which is needed for your make and model after reviewing the manufacturer specifications.

Every replacement follows a strict six-step process:

1. Pre-Installation Check — We verify the correct glass using your VIN and specifications.

2. Safe Removal — The damaged windscreen is carefully cut out using specialist tools, protecting your paintwork and body structure.

3. Frame Preparation — Old urethane is removed, the pinch weld is cleaned and primed for maximum bonding strength.

4. Professional Fitting — Factory-spec, UK-approved glass bonded using manufacturer-approved structural adhesive.

5. ADAS Calibration — Cameras and sensors are recalibrated to factory specifications (if your vehicle requires it).

6. Quality Check — Final leak and safety checks confirm your windscreen meets UK standards.

From the moment the technician starts, you can normally drive your car again within about two hours. That includes ADAS calibration where needed, which is done while the adhesive sets. Your technician will confirm exact timing.

Windscreen replacement cost varies based on vehicle age, glass size, windscreen features, and ADAS technology. Older vehicles with simple windscreens typically fall into the lower price range, while newer luxury cars with heated, acoustic, or sensor-equipped glass cost more.
