What changed in ADAS calibration in 2026

Thatcham updated its ADAS code of practice in late 2025, and BS10125 audits in 2026 are now actively checking calibration paperwork against the operations on the repair plan. Where a repair touches a panel known to host or affect ADAS sensors — front bumpers (radar, camera), windscreens (forward camera, lane-keep), grilles (radar), wing mirrors (blind-spot), tailgates (rear radar) — auditors expect a documented calibration record on the job file.

The change isn't a new requirement. Calibration has always been needed when sensor geometry is disturbed. What has changed is the documentation expectation and the audit enforcement.

Static vs dynamic calibration

Static calibration uses target boards in a controlled bay environment — required for most forward cameras and many radar units. Dynamic calibration uses a road test at defined speeds with the OEM diagnostic tool active. Most modern vehicles need both.

A bodyshop that only owns dynamic calibration tooling cannot realistically calibrate the majority of modern vehicles in-house. Procurement teams should ask any panel network: how many sites have static calibration bays, and which OEM target board sets do they hold? Solution Repair Group publishes both numbers openly above.

Why in-house calibration matters

Sublet calibration adds 1-3 days to cycle time on average and creates a documentation gap if the sublet provider doesn't return paperwork in the format BS10125 audits now expect. In-house calibration removes both problems.

The 19 Solution Repair Group sites with in-house calibration handle around 90% of network-wide ADAS work directly. The 4 sites without in-house calibration use a single approved sublet provider with a standardised documentation pack, so even sublet work returns the audit-grade paperwork insurer panels need.

OEM coverage

Network-held target board sets cover BMW (including i-Series), Mercedes-Benz (including EQ), VAG group (Audi, VW, Škoda, SEAT, CUPRA), JLR (Jaguar, Land Rover, including EV), Volvo (including EX), Tesla (Model S/3/X/Y), Honda, Kia, Hyundai (including IONIQ) and Stellantis-group brands (Vauxhall, Peugeot, Citroën, Fiat, Jeep, DS).

Per-brand calibration capability is maintained on each /manufacturer-approvals/{brand} page so insurers and AMCs can verify coverage for their specific vehicle mix.
