ADAS Calibration: Should Your Garage Be Offering It?

If your garage does wheel alignments, windscreen replacements, suspension repairs, or accident work, you're almost certainly sending some customers away with uncalibrated driver assistance systems. That's a growing problem — both for customer safety and for your liability as a garage. Here's what you need to know about ADAS calibration and how to decide what to do about it.

What ADAS is and why it matters after bodywork or wheel alignment

ADAS stands for Advanced Driver Assistance Systems. It covers the growing range of active safety and convenience technologies that are now standard equipment on most new cars: lane departure warning, automatic emergency braking (AEB), adaptive cruise control, blind spot monitoring, rear cross-traffic alert, traffic sign recognition, and parking sensors.

These systems rely on sensors — cameras, radar units, and ultrasonic sensors — that are calibrated to very precise angles and positions. When anything changes the geometry of the vehicle or the position of those sensors, the calibration shifts. That includes:

• Windscreen replacement (the forward-facing camera is almost always mounted to the windscreen)
• Wheel alignment adjustments
• Suspension work — spring or strut replacement, lower arm, subframe
• Accident damage repair, even minor front or rear bumper work
• Steering rack replacement
• Any work on a camera or radar mounting bracket

An uncalibrated lane departure system might generate false warnings. An uncalibrated AEB system might brake unnecessarily, or worse, fail to brake when it should. The consequences of sending a car away without proper calibration can be serious.

The ADAS liability issue

This is the part that catches many garages out. If your garage completes a wheel alignment, the car leaves, and there's subsequently an incident where a driver assistance system fails to operate correctly, there is a real question about whether your garage's failure to check and perform ADAS calibration contributed to the outcome.

Courts and insurers are increasingly aware of ADAS calibration requirements. The IMI and the Vehicle Body Repair Association (VBRA) have both published guidance stating that ADAS calibration is a mandatory part of any repair that could affect sensor alignment. "We didn't know it needed calibrating" is not a strong defence when calibration requirements are published in vehicle manufacturer technical data.

The practical minimum for every garage: check whether the vehicle has ADAS, identify which systems it carries, check whether the work being done requires calibration (manufacturer service data specifies this), and either perform calibration or tell the customer in writing that calibration is required and refer them to someone who can do it.

What equipment ADAS calibration requires

There are two types of ADAS calibration: static and dynamic.

Static calibration is done in the workshop. It requires a large calibration target — a specific printed board or reflective panel — positioned at a precise distance and angle in front of the vehicle, with the vehicle parked on a level surface. The diagnostic tool then instructs the camera or radar to recalibrate to that target. A static calibration rig for a single brand can cost £3,000–£8,000. A multi-brand static setup covering the most common ADAS systems runs £8,000–£25,000.

Dynamic calibration is done while driving. The vehicle is driven on a road with clear lane markings and good visibility while the diagnostic tool completes the calibration procedure. This requires less physical equipment but needs a suitable route and the right diagnostic software.

Some vehicles require both static and dynamic calibration in sequence. The requirements vary by manufacturer and by which specific ADAS systems are fitted.

The business case for adding ADAS to your garage

ADAS calibration commands good margins. Calibration jobs typically range from £100 to £350 depending on the system and whether static or dynamic calibration is required. A garage doing 10 windscreen-adjacent jobs a week and capturing the calibration work on half of them is adding meaningful revenue.

It also adds defensible value. Garages offering ADAS calibration in-house can present complete repair packages — alignment plus calibration in one visit — rather than telling customers to go elsewhere for part of the job.

The counterargument is capital cost and space. Static calibration requires a large, level, well-lit area — typically at least 10 metres of clear space in front of the vehicle. Not every workshop has that, and the equipment investment is significant. For a garage with limited space, in-house static ADAS may simply not be practical.

When to refer out and when to invest

For garages that don't have the space or capital for a full ADAS setup, the right answer is usually a mobile calibration partnership. Several companies offer mobile ADAS calibration services — they come to your workshop with their own equipment and do the calibration on-site. You charge the customer, pay the mobile provider, and keep a margin. The customer gets a complete job without visiting a second location.

A sensible decision framework:

• Fewer than 5 ADAS-triggering jobs per week: use a mobile calibration partner
• 5–15 jobs per week: run the numbers on in-house equipment — it may pay back within 18 months
• More than 15 jobs per week: in-house equipment is almost certainly justified

Whatever you decide, have a written process. Know which jobs require calibration, know how you'll handle it (in-house or referral), and make sure every relevant job sheet includes confirmation that ADAS has been addressed.

How to market ADAS calibration locally

Most car owners don't know what ADAS calibration is, which means the marketing angle is education rather than pure promotion. Content that explains why calibration matters after a windscreen replacement or alignment tends to perform well in local search because it's answering a question people actually ask.

On your Google Business profile, list ADAS calibration explicitly as a service. In your service confirmations, mention it when relevant — "your vehicle's lane departure system has been recalibrated following your alignment" is a detail that builds trust even with customers who didn't realise it was needed.

If you want to manage ADAS calibration jobs alongside your other work without adding complexity to your scheduling, Garagess handles job tracking and customer communication for specialist services as well as routine work. Get in touch to find out more.
