Our passion is enabling technicians to be the best that they can be, through the very best quality technical training, support and knowledge and skills development. We operate from a state-of-the-art skills centre in Bridgwater, Somerset which is equipped with late model vehicles and a vast range of leading tools and equipment.


The company is led by aftermarket technical expert James Dillon. He is supported by a team of technical, training and diagnostic experts who have been delivering technical automotive training courses for technicians for many years. The business was first established in 1989 by James Dillon.


At TTHQ, our core goal is to inspire technicians in their learning journey and to fuel the fire of their devotion to automotive. Training is about more than learning some useful stuff (although that’s great too). It’s about fundamentally changing mindsets to see challenges in a different way and aiding techs in the journey to automotive excellence.


Our team is happy to answer any question or query you may have. Send us an email at and we’ll get back to you as soon as we can.
