Next in our Meet the Team series is Barney Jacob, our head of operations and someone who plays a huge role in the development of Gas Mark 1 Herts Bathrooms and Kitchens.

Barney joined in 2002 as a plumbing apprentice and what followed has been an impressive career journey spanning more than 2 decades.

From working on the plumbing side Barney went on to specialise in bathroom installations before helping to develop the kitchen department. He later moved into surveying and project management before taking on his current role as head of operations.
Today Barney is involved in almost every project that comes through the business from initial surveys and planning, through to installation. His knowledge, experience and attention to detail help ensure our works run smoothly and customers receive a high level of service and care which we pride ourselves on.
Barneys contribution goes beyond his role- he has been instrumental in training and developing the next generation of engineers here.
We are incredibly proud of his journey with us and his career is a great example of what can be achieved through commitment, hard work and a willingness to keep learning and developing.
Thank you Barney for the last 20 years, we can’t wait to see what you bring to the next 20!

Would you like to meet the team behind the scenes? Starting with 2 people who started it all …

Meet John and Tony, the directors and founders of Gas Mark 1. Their story began back in 1978 when they met at Francis Combe secondary school in Watford. After leaving school they joined British Gas as apprentice gas engineers and went on to spend 8 years working as heating engineers there.

They decided to take the leap and start a business of their own so in 1993 Gas Mark 1 was born.
2 friends, a wealth of engineers’ experience and determination to build a business, based on customer satisfaction and value for money, has grown into what you see today.

From the first showroom on St Albans Road to our current 8000square foot space on Market Street, John and Tony have continued to be hands on and passionate about the team around them.

They’ve always believed in investing in people. Their first apprentice Darren is still with the company and every one of our current engineers started their career with us.

30 years on John and Tony are still part of the day to day business, working alongside their team of around 40 staff, looking ahead to the next chapter.

So if you’ve ever wondered who’s behind Gas Mark 1 … now you know!

Sunday sort out! ⚒️✨
Nothing feels better than starting a new week with a checked off to do list!
Whether it’s a slow draining sink, a noisy radiator or an overdue boiler service, now is the time to get it sorted.
Small plumbing and heating issues don’t fix themselves, but getting them resolved doesn’t have to be a hassle.
Our engineers are fully organised and ready to go, ensuring you get swift service, minimal disruption, and efficient long lasting fixes every single time.
Don’t wait for a small trickle to turn into a major headache - prevent the chaos before it starts!
