The company’s clients have included Rolls Royce, Bentley, Ford of Europe, Jaguar Land Rover, BBC TV, National Geographic channel, PSA, ZF and many companies from the motorsport world. Although all the projects are based in or around the world of automotive engineering, the variety of work is what RHEL founder Ralph Hosier relishes.

After six years; during which he was involved in the development of cars such as the Mondeo and KA, as well as various SVE projects; Ralph formed RHEL. His first client was Rolls Royce and Bentley (when they were one company) where he worked on modernising the classic V8 engine and building prototype and experimental cars.

The extensive RHE workshops


RH Engineering training course in action

We firmly believe in the importance of sharing skills. We are stronger when we have the ability to do things for ourselves. and, with some skills, there is a crucial need to keep the knowledge alive as an investment for the future.

Our courses are all designed in-house, built around real-world needs, and are a reaction to the requests for help and advice we often receive. The expanding range of courses are flexible, designed to meet your requirements, which means we can also provide bespoke courses for individuals, groups, clubs and companies.

RHEL has, from this base, developed into a multi-faceted, flourishing and established business. Commissions undertaken have ranged from building various racing and rally cars, to designing auxiliary power units for commercial vehicles and power train development for large European mass-market vehicle manufacturers. Each new challenge is met with the same high level of enthusiasm inquisitiveness and innovation.

Courses are offered for people with all skill levels, from beginner to expert.
