The DVSA is set to change the requirements for the calibration of some testing equipment from 1 April 2023.

Decelerometer calibration and the calibration of roller brake testers (RBT), plate brake testers (PBT) and headlamp aim testers are all affected.

From April, all decelerometers must be calibrated at intervals not exceeding one year, a change from the current two year cycle.

Decelerometer calibration certificates issued before 1 April 2023 will be acceptable until they expire.

Calibration of roller brake testers (RBT), plate brake testers (PBT) and headlamp aim testers
Calibration of brake testers and headlamp testers will no longer be acceptable if completed by vehicle testing station (VTS) staff.

Calibration can only be completed by either the original manufacturer, a company that has taken over responsibility for equipment support from the manufacturer or a calibration specialist.

Testing stations that employ an independent calibration specialist must be able to demonstrate their technical competence to DVSA upon request.
