Manufacturer schedules and when to book How Long Does ADAS Calibration Take? Typical durations per service and what affects them
After a windscreen replacement, your forward-facing camera must be recalibrated to restore lane departure warning, traffic sign recognition, and forward collision alert.
Our IMI-certified technicians use manufacturer-approved targets and OEM-grade equipment to ensure millimetre-precise alignment at over 70 UK locations.
The most common ADAS calibration requirement in the UK
Every windscreen replacement detaches the forward-facing camera. Even a fraction of a degree misalignment causes lane keeping, sign recognition, and emergency braking to malfunction. Recalibration is mandatory — not optional.
If a stone chip or crack sits within the camera's field of view, the repair can distort the lens path. Technicians often recommend a calibration check after repairs in the critical zone above the rear-view mirror.
Non-OEM windscreens can differ in thickness or curvature by fractions of a millimetre. These tolerances affect how the camera reads the road. Calibration ensures the system compensates for any optical variation.
Windscreen calibration applies to any vehicle with a forward-facing camera:
If your vehicle alerts you when drifting out of lane, it uses a windscreen-mounted camera that requires recalibration after glass replacement.
Speed limit display, overtaking restrictions, and advisory signs are read by the same camera. Misalignment means the system reads signs late or misidentifies them entirely.
The forward-facing camera works alongside radar to measure closing distances. Without calibration, the system may brake too late, too early, or not at all.
A precise, controlled process that restores your camera system to factory accuracy.

Our technician inspects the windscreen fitment, verifies the camera bracket is secure, and confirms the new glass meets the required optical standards.
Using manufacturer-approved targets positioned at precise distances, the camera is recalibrated in a controlled environment to restore exact alignment.
You receive a calibration certificate confirming the camera is aligned within manufacturer tolerances. This document is required by most insurers.

Expert answers to common questions about this service
Yes. If your vehicle has a forward-facing camera mounted behind the windscreen — which includes most vehicles manufactured after 2016 — calibration is mandatory after every windscreen replacement. The camera's position changes when the glass is removed, even if the bracket appears undisturbed.
Our IMI-certified technicians use OEM-grade equipment at over 70 UK locations. Fixed pricing, no hidden fees, and a full calibration report with every service.
