Jamie Clarke and Peter Holliday of Clarke Energy will be stepping down as CEO and chief financial officer, respectively.
Jamie Clarke is the son of Jim Clarke, the founder of Liverpool-headquartered Clarke Energy and has led the business since his appointment as CEO in 2010. He has led the business to consistent growth over this period with the company having exceeded £500m of annual revenue in 2024 with expected growth in 2025.
Clarke Energy was acquired by the Kohler Company of Wisconsin in 2017. In May 2024, Kohler Energy became a separate, independent business, operating as Rehlko.
The move forms part of a planned succession, with the two leaving their roles from 1 May.
Kyle Quinn succeeds Clarke as president and Sharon Wright will take on Holliday’s position as group finance director.
Both Clarke and Holliday will be retained in non-executive roles and will be supporting the business going forwards.
Clarke commented: “Having committed over 50 years between us to the growth and development of Clarke Energy, we still have a huge passion for the business and have both accepted ongoing non-executive roles and will remain involved in the business going forward.”
Quinn added: “The business continues to thrive and now covers 27 countries providing industry leading distributed energy solutions for our customers. On behalf of the Clarke Energy leadership team, we look forward to continuing in their footsteps on the next phase of the Clarke journey.”
