From 2026, BS10125 audits expect documented ADAS calibration on any panel replacement that affects sensor mounting, alignment, or aim — including bumpers, windscreens, and grilles. Sublet-only calibration without in-house verification is no longer considered best-practice. Networks with in-house static and dynamic calibration capability are the lower-risk panel partner.
What changed in 2026
Thatcham updated its ADAS code of practice in late 2025, and BS10125 audits in 2026 are now actively checking calibration paperwork against repair operations. Where a repair plan 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 — what insurers should ask
Static calibration uses target boards in a controlled bay environment. It's 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 ADAS readiness
Across the Solution Repair Group network, 19 of 23 sites are ADAS-calibration-capable in-house, with the remainder using a single approved sublet provider with documented sign-off authority. The network runs target board sets for the major OEM groups including BMW, Mercedes, VAG, JLR, Volvo, Tesla, Honda, Kia, Hyundai and Stellantis brands.
Every job file includes a calibration record where applicable, signed by an IMI-qualified technician, with diagnostic report attached. This is the documentation pattern BS10125 auditors are now expecting as the baseline.
