Our engineers

All of our work is carried out by highly qualified experienced engineers, with all gas work being undertaken by fully qualified Gas Safe accredited engineers.

Gas Mark 1 pride ourselves on our in-house apprenticeship scheme. Annually, we have been taking on and providing careers to youngsters for over 20 years, many of whom are still working for us now! We work closely with local colleges to make sure that our apprentices are developing to the best of their capabilities in order to maximise their potential.

We believe training apprentices is one of the most important aspects of our business as our development program ensures we can produce high quality engineers and develop individuals you'll be happy to have in your home.

A Big Thank you to all the staff at Gas Mark 1. My wife and I really appreciate the work Jason and his colleague have done in our house, fitting the boiler and the fire - fantastic workmanship, very clean and tidy and professional. They made the whole process very easy - my wife had been dreading it. All in all we are very, very pleased with Gas Mark 1 from sales to completion and we will be more than happy to recommend you to anyone else who needs a boiler fitting or wants a fire.
