In the commercial transport industry, downtime is the biggest threat to profitability. When your trucks stop, your business stops. That’s why fleet operators across London, Reading, Heathrow, Oxford and surrounding areas rely on Stark Fleet for fast, reliable and professional repair solutions. Whether it’s HGV & truck repairs, complete HGV engine repairs and full engine rebuilds, routine maintenance, diagnostics, or specialist component replacements, Stark Fleet offers a comprehensive service designed to keep heavy-duty vehicles running at peak performance.
This in-depth guide explains the full range of services we provide, why routine maintenance is essential for fleet reliability, and how our team helps operators reduce breakdowns, extend vehicle lifespan and maintain full compliance with UK safety requirements. With years of hands-on experience and industry-leading equipment, Stark Fleet is the trusted choice for commercial vehicle repairs.

Why Your Fleet Needs Reliable HGV & Truck Repairs
Heavy goods vehicles operate under extreme conditions. Long distances, heavy loads, irregular driving patterns, and continuous wear all contribute to component fatigue. When a fault is ignored or temporarily patched instead of repaired correctly, it often leads to more expensive failures later.
Stark Fleet offers complete HGV engine repairs and full engine rebuilds, using high-quality components and industry-standard rebuild techniques. Whether your truck is experiencing loss of power, oil contamination, overheating, blue/white/black smoke, or warning lights, we deliver precise fault identification and repair solutions tailored to your vehicle’s needs.
Reliable repairs mean:
Maximised fleet uptime
Lower operating costs
Greater fuel efficiency
Longer vehicle lifespan
Better safety performance
Reduced breakdown risk
Fleet managers across London, Reading, Heathrow and Oxford count on Stark Fleet for dependable commercial vehicle support.
Complete HGV Engine Repairs and Full Engine Rebuilds
One of the most critical services we offer is complete HGV engine repairs and full engine rebuilds. High-mileage trucks often suffer from wear-related issues that basic repairs cannot resolve.

A Stark Fleet full engine rebuild typically includes:
Full engine strip-down
Deep cleaning and decarbonisation
Precision inspection of pistons, cylinder liners, camshaft, crankshaft and bearings
Replacement of worn components
Cylinder head reconditioning
Fuel system testing
Turbocharger inspection
New gaskets, seals, filters and fluids
Reassembly with torque-controlled settings
Full performance and pressure testing
