Having started work in the gas industry in 1982 as an apprentice I qualified 3 years later winning National Apprentice of the year! At the age of 28 John and myself started Gas Mark 1 and together we have built the business by doing our best to give our customers a great experience. By adopting this attitude we have thousands of repeat customers, a foundation to our business. It will still be me visiting you at home to quote for boiler and bathroom installations, while I continue to mentor the team and grow the company.

As co founder of Gas mark 1 I am still a Gas safe registered engineer who spends a lot of time designing and overseeing the more technical work including designing larger heating systems with multiple boilers, underfloor heating and in some cases air source Heat Pumps. As the technical director I will quality control work with site visits, often helping the engineers out. Away from work I am a keen Watford football fan who has been a season ticket holder for more than 40 years.

I have been working at Gas Mark 1 for 5 years and have completed the plumbing and heating course at West Herts College. Through my apprenticeship worked alongside senior engineer Tom H on big site jobs, doing underfloor heating and some air source heat pump installations.

I have been in the plumbing and gas industry for 40 years. I went from being self-employed to working full time with Gas Mark 1 over 21 years ago. My role here is service and maintenance, I specialise in diagnostics of gas appliances, all types of heating, plumbing issues and repairs, including Warm Air Units.

Jamie has been with Gas Mark 1 and Herts Bathrooms and Kitchens for over 20 years, bringing a wealth of experience across multiple roles. He began as a bathroom salesman, moved into kitchen design, and later became an installer—where his practical skills and keen eye for detail truly stand out. Jamie particularly enjoys bringing new bathroom and kitchen designs to life, seeing each project through from concept to completion.

I have worked for Gas Mark 1 since I left school in 2013. This allowed me to complete my apprenticeship with the company.

My current role in the company is part of the kitchen installation team. I can also adapt and work on bathroom installations or maintenance jobs where needed.

I have worked for Gas Mark 1 for 17 years, starting out as an apprentice and now working as a senior engineer. I take on all aspects of plumbing and heating work but also really enjoy training our new apprentices, guiding them through their qualifications. I have experience managing larger projects for Gas Mark 1, which has led me to having more involvement in leading the team.

In 2018 I joined Gas Mark 1 as an apprentice and have been gaining hands on experience ever since.

I joined Gas Mark 1 as an apprentice in 2013 and since then I have experienced all aspects of the plumbing and gas work involved in what we do. After completing my apprenticeship. I chose to pursue the maintenance and fault-finding side which includes breakdowns and servicing, and more recently the electrical side to heating systems. I enjoy the maintenance side of the job as I feel there is something new every day.

I started at the company in 1998 and did my apprenticeship here, becoming a fully qualified engineer in 2003. John and Tony have known me since I was 15 as I was so impressed by all the pipe work Gas Mark 1 did when they installed a boiler at my parents house I did my work experience with them! This helped put the company on the map for other kids in the area to come and have a go, some have also become apprentices and even now fully qualified gas safe colleges.

I mainly work as a central heating installation engineer but also do fault finding and gas appliance servicing.

I work on both bathroom and kitchen installation projects at Gas Mark 1. I started as an apprentice and have developed and refined my skills over the years working here.

I have been working for Gas Mark 1 for 5 and a half years and completed my apprenticeship here alongside study at West Herts College. I really enjoy heating jobs and have worked closely with Jason on lots of central heating projects.

I started out at Gas Mark 1’s first apprentice with Tony as my mentor. Having over 25 years hands on experience in the industry I have a wealth of knowledge in gas and electric fires, plumbing and heating.

I started in 2003 as office admin, supporting Russell who mentored me. Over time I learnt customer service as a valuable skill. I deal with booking in work and sourcing and secure spares for gas appliances, prioritising getting customer’s up and running when their fires, boilers, cookers break down.

I took a special interest in learning about the fires from Steve, who established the company, and enjoyed the interaction with customer and learning about new products, staying up to date with industry developments.

I manage the apprenticeship scheme here at Gas Mark 1, and I am proud to say many of the apprentices, who are now fully trained engineers, were signed up by me.

More recently I have taken on the role of managing the stores and take the lead on the purchasing of all goods required for the gas engineers through our suppliers.

I started with Herts Bathrooms in 2001 in the warehouse and as a delivery driver, transporting goods from our yard out to site. I left for a short period of time and then returned to the business to work in the bathroom show room. I started learning about the kitchen goods and the fires and then moved downstairs to work in the office for Gas Mark 1.
