A bumper with a radar unit behind it is now a £1,500- £2,000 job. Five years ago, it was paint and plastic. A windscreen on a post-2014 car is no longer a glass job. A minor collision on an EV can write the vehicle off entirely.

The vehicles changed. The money changed with them. Did your pricing, staffing, and capabilities change, too? Here’s what repair shop owners who are keeping up with the changes are charging.

ADAS calibration: the biggest missed revenue line in most auto repair shops

Every structural repair, bumper replacement, or geometry job on a modern vehicle triggers a calibration requirement. Most bodyshops either sub it out and lose the margin, or miss it entirely and carry the liability without billing for it.

ADAS calibration is safety-critical. The liability sits with the bodyshop carrying out the work. If you are not billing for it, you are absorbing the risk for free.

A 2026 dataset on UK ADAS calibration demand found that 49% of calibration enquiries originated from bodyshop and garage customers referred out after bumper, collision, or parts work. Nearly half the calibration revenue those jobs should have generated left with the referral.

The gap between completing the repair and capturing the full value of the job is where money is being lost.

Windscreen replacement- not a glass job anymore

A windscreen on a post-2014 vehicle almost always means a camera. Which means calibration on top of the glass.

The average cost of windscreen replacement in the UK in 2026 is £345. For newer vehicles handled by national chains, that average rises to £659. Add ADAS calibration (required on any vehicle with embedded cameras or sensors) and the total job value climbs further, with calibration alone adding £150 to £400 depending on the vehicle.

Shops that carry out both the replacement and the calibration in-house retain the full margin. Shops that cannot, refer the calibration out and watch someone else bill it.

EV repair: high complexity, high labour value

Electric vehicles are arriving in repair networks faster than technicians are being trained to work on them. That skills gap has a direct commercial upside for shops that have invested correctly.

At the UK Garage and Bodyshop Event 2026, multiple training providers showcased high-voltage systems to meet growing demand from workshops looking to retain work previously referred to dealerships.

EV batteries account for up to 40% of a vehicle’s total value. Even minor collision damage near the battery housing frequently results in a total loss determination, because current repair protocols often mandate full battery replacement at a cost that exceeds what the car is worth. According to Thatcham Research, battery-related issues remain the primary concern for 41.7% of repair professionals. Shops with the right high-voltage capability take on those jobs rather than declining them. The labour hours are higher, and the specialist rate is justified.

Better diagnosis, better margin

According to Bodyshopmag, misdiagnosis is adding over £1,000 to repair bills, with delayed or missed faults adding an average of £400 to the final cost. On modern vehicles with interconnected electronic systems, the gap between what a surface inspection reveals and what a full diagnostic scan finds is where supplements come from and where margin disappears.

Shops that invest in diagnostic capability (and technicians who know how to interpret what the scan is telling them) write better estimates from the start. The results? Fewer insurer disputes, fewer mid-job surprises, fewer comebacks.

The diagnostic checks that protect the margin on a modern repair include:

Pre-repair scan to identify all fault codes before work begins
Mid-repair scan after structural or electrical work to catch cascading faults
ADAS system verification before any calibration is attempted
Post-repair scan to confirm all systems are clear before handover
Documentation of all scan results for insurer and warranty purposes

Each of these is a billable step.

Accurate estimating: the most undervalued margin protection tool in automotive

A weak estimate creates a scope problem, a parts problem, and an insurer dispute that plays out over weeks. Repair costs are up 8% in the last year, and labour rates are up 5%. Every supplement cycle you avoided is a margin saved. A damage assessor who documents ADAS requirements, structural complexity, and correct labour times is protecting your gross margin on every job.

SMART car repair: volume, turnover, and fleet opportunity

SMART repair does not carry the same per-job value as full collision work. At £190 per panel as of March 2026, it is fast, high-volume, and well-suited to fleet contracts where throughput and contract stability matter more than per-job margin.

In 2025, the insurance sector of Smart Repairs UK’s business grew by 50% in a single year. The demand is there. It goes to the shops with the capacity and the technicians to handle volume.

Where you can make a profit: a service comparison

Every service covered in this article carries a different job value and a different margin dynamic. Here is how they compare at a glance.

Service	Typical UK job value	Key revenue driver
ADAS calibration (standalone)	£150 to £400 per calibration	Fully billable specialist labour with documented liability
Windscreen + calibration (ADAS vehicle)	£500 to £1,000 combined	In-house glass and calibration retains full margin
EV collision repair (minor to moderate)	£1,000 to £10,000+ depending on battery involvement	Specialist rate and retained work vs dealership referral
Aluminium/modern body repair	£600 to £1,800+ per panel replaced	Premium labour rate on specialist material
SMART repair (fleet)	£150 to £250 per panel	Contract volume and mobile throughput
Bumper with sensor/calibration	£1,500 to £2,000 replace and recalibrate	What looked like a cosmetic job now carries full tech billing

Every row where your shop cannot deliver is revenue going somewhere else.

What Drives Auto Body Shop Profitability in 2026?

It all requires either a skilled technician who knows what they are doing or an estimator who can document and price it correctly.

The shops making money from ADAS calibration are not doing so because they bought the equipment. They are doing so because they have the staff to operate it, bill for it accurately, and produce the documentation insurers need.

That is a staffing and skills question as much as a commercial one. If hiring the right people is the bottleneck, that is a conversation worth having. Let’s have it.
