SUPPLY chain membership organisation British Water has appointed RSE chief executive Stephen Slessor as its new chair. He succeeds Dr Mark Fletcher, director and global water business lead at Arup.
Slessor brings experience in engineering, digital construction approaches and strategic leadership to the role. He has been chief executive of water technology company RSE since January 2024, overseeing a period of growth, with expansion initiatives across the UK and internationally. He previously worked for construction company Galliford Try for 17 years.
“I’m humbled to step into the role as chair of British Water as the water sector steps up to meet the most pressing challenges in the coming decades, whether that be related to climate, regulatory changes or skills development,” Stephen Slessor stated. “The input and innovation of our growing membership is more critical than ever in delivering a more sustainable and resilient UK water ecosystem, and I will endeavour to champion the vital work of British Water at every turn.”
Lila Thompson, British Water chief executive, added, “We are delighted to welcome Stephen Slessor as chair of British Water. He brings deep industry expertise and a forward-thinking approach at a time when the water sector is undergoing significant transformation.
“Stephen’s passion for innovation and commitment to collaboration align strongly with the British Water mission of supporting a sustainable and high-performing water sector. I look forward to working with him as we continue to champion the voice of the supply chain and drive meaningful change across the industry.”
British Water supports the work of its members through a portfolio of events, forums and focus groups. As chair, Slessor will work with the trade body’s board to help grow the membership and build the resilience of the organisation, while holding government to account to ensure its pledges on skills and opportunities in the water sector are realised for the supply chain as well as the water companies.
British Water said it has extended sincere thanks to Dr Fletcher as he steps down from his role as chair. Lila Thompson said his leadership had brought ‘invaluable insight and vision’ to the organisation.
