Lee Jackman


Gas, Plumbing and Heating Engineer

I started my modern apprenticeship in 1996 with Sheffield Direct Services (Sheffield City Council). I worked on various sections, with the work ranging from basic plumbing to full heating installations and gas maintenance and repair. I spent a total of ten years gaining experience and knowledge.

In 2006 I left and formed my own company “High Efficiency Low Carbon Ltd. By forming my own company I have been able to keep learning new technologies and work on larger projects, fully designing systems to meet customers’ requirements.

I have passion for my job and enjoy working with customers’ and other trades to achieve and develop systems and plumbing projects into reality.
