Servicing
We offer three levels of mechanical servicing - Service A, B, and C - so you can choose the best fit for your vehicle and maintenance schedule.

Mechanical & Electrical Repairs
Our team handles all mechanical and electrical repairs, from minor wiring issues to major component faults. We diagnose fast and fix properly.

Truck & Trailer Maintenance Repairs
Whether it’s tyres, suspension, load anchors or lights, we handle the day-to-day wear and tear that comes with running trucks and trailers.

Diagnostic Fault Finding
Using advanced diagnostic tools, we accurately pinpoint faults, then carry out the necessary repairs to clear codes and restore performance.

Trailer ABS Diagnostics & Repairs
ABS faults can impact braking and compliance. We use specialist gear to diagnose and repair trailer ABS issues to get you road-ready.

Major Component Overhaul
We rebuild engines, gearboxes and diffs in-house, saving time and ensuring every component is overhauled to spec by trusted hands.

Fixed Price Servicing
Want to manage upfront costs? Ask about our fixed price service options for fleet and regular customers—no surprises, just solid work.

Brake Servicing & Repairs
We inspect, repair and replace brakes to keep your stopping power sharp. From pads to drums, we’ll make sure you’re safe to drive.

Preventive Maintenance Repairs
We’ll help you catch small problems before they become big ones. Our preventive maintenance repairs are all about uptime and safety.
