Michael Gibson

Managing Director

Since graduating from Manchester Metropolitan University in 2006, Mike has enjoyed several roles within operational and managerial functions. Over the years, he has developed a strong passion surrounding the role that business can play in improving the local area.

Starting out at Balfour Beatty, an FTSE 250 UK Construction company, Mike covered various roles within mobilisation, transition and operations, progressing for several years before moving on in 2013 to join multinational energy company, ENGIE.

Responsible for leading the operational service transformation, he was quickly appointed as Partnership Director in 2014 for ENGIE’s ten-year services, energy and property partnership with Kingston Upon Thames Council.

As a result of his success within ENGIE, Mike was appointed as Managing Director of Quest Services in 2016, a joint venture between ENGIE UK and Cheshire West and Cheshire Council. He remains a Non-Executive Director there, delivering a range of services across the borough.

In 2019, Mike was appointed to his current position as Managing Director at Storengy UK, part of the ENGIE group. Here, he uses his position and influence to foster a community culture, improving educational links to industry and creating a more inclusive economy. Storengy UK has embarked on a journey to become carbon neutral by 2025, and is focused on supporting the UK's energy transition through growth in green gases, such as Hydrogen and biogas.

Not only that, as giving back is something of huge importance, he is also a member of several boards and initiatives outside of work. Previously a leader for the 2019 West Cheshire Poverty Truth Commission, Mike is currently a board member of the Mid-Cheshire Development Board, a deputy chair of a local primary school board of governors, a LEP enterprise advisor for a local high school and sits on the BiTC North-West Advisory board.

In the little spare time he allows himself, you will often find Mike spending quality time with his children, and squeezing his hobby of woodworking in, whenever possible.
