Tachograph Fitment, Calibration & Inspection
Trailer Aid Ltd is an approved tachograph fitment and calibration centre. Analogue and digital units fitted, calibrated, inspected and certified – keeping your fleet legal and your O-licence protected.
Tachograph compliance is not optional. An out-of-calibration or incorrectly fitted tachograph puts your O-licence – and your drivers' livelihoods – at risk. As an approved tachograph fitment and calibration centre (working to DVSA standards, formerly VOSA), Trailer Aid Ltd handles the entire lifecycle: fitment, calibration, statutory inspection and certification.
Our Tachograph Services
- New fitment – supply and installation of analogue and digital tachograph units to new and existing vehicles
- Recalibration – two-yearly digital and six-yearly analogue recalibration with certification
- Statutory inspection – two-yearly analogue tachograph inspections
- Repair & replacement – faulty heads, senders and wiring diagnosed and rectified
- Fleet compliance management – we track expiry dates across your fleet and remind you before deadlines
Why It Matters
The tachograph is the legal record of your drivers' hours and your vehicle's speed and distance. DVSA roadside checks and site visits will examine your calibration plaques and records. A missed recalibration date is an easy prohibition – and an avoidable one. Because we also handle your fleet maintenance and trailer servicing, tachograph dates can be aligned with your safety inspection schedule so one visit covers everything.
One Visit, Full Compliance
Combine tachograph calibration with a safety inspection, MOT preparation or service visit and minimise vehicle downtime. Our workshop is minutes from the M1 and A5 – easy in, easy out.
