Team

Two pioneers, four leaders and four directors empower a 150 strong team of sustainability change makers at Sustainable Energy First.

Four leaders

Michael Abbott, CEO

Michael Abbott

Chief Executive Officer (CEO)

Michael studied electrical engineering, which led him to start his career as a trainee cost analyst for an energy consultancy. He has had a decorated, and substantial, career during his 35 years in the sector, from privatisation and deregulation of the industry, to pioneering what is now known as flexible procurement trading and corporate PPAs. Michael has also been involved in developing anaerobic digestion (AD) technology and, as a founding member of the trade body ABDA, helped to establish AD within the UK renewable energy mix.

He thrives on the ongoing development and challenges the industry brings, from the mass UK adoption of EVs to the exciting growth in renewable energy generation.

Michael’s enthusiasm for the sector hasn’t wavered in 35 years and has led the transition of BiU to Sustainable Energy First from the front, looking forward to the next chapter in the industry – mass decarbonisation.

Tom Ellis CFO

Tom Ellis

Chief Finance Officer (CFO)

Tom joined BiU in 2015 as Finance Director, to support the business during a period of significant growth. He brings a range of experience to the board, having started his accountancy journey at KPMG, and progressing to become a senior financial professional within a variety of businesses. As BiU evolves into Sustainable Energy First, Tom continues to focus his support on the ongoing growth of the company.

As CFO, Tom knows first-hand the impact sustainable investment, and policy, have on business operations, as well as potential risks of inaction on climate matters. His goal is to ensure our business, as well as our clients’, thrive economically, as well as environmentally.

Shaun Clarkson COO

Shaun Clarkson

Chief Operating Officer (COO)

Shaun studied as a microbiologist, and throughout a well-developed energy career, has always had an eye on his environmental roots. Early in his career he trained as an oil and water analyst, and soon progressed to management level – overseeing business growth in water analysis and leading the integration of environmental compliance subsidiaries into core operations. This culminated in his appointment as an operations director.

Shaun joined BiU in 2018 to strengthen the operational side of the business. He oversaw the growth of the company’s IT infrastructure and software development teams, which has revolutionised what we deliver for clients. In 2019, Shaun was promoted to COO, with the goal to evolve the company’s approach to energy management and challenge the norm in the industry.

Shaun has a long-life passion for the natural world, and he firmly believes that reducing a business’s environmental footprint is both the right choice, and the economic choice.

Anthony Mayall, CCO

Anthony Mayall

Chief Commercial Officer (CCO)

Anthony entered the energy sector 30 years ago as an electrical engineering apprentice and could be found at times in the depths of a hydro station’s inner workings building out switchgear and control systems. His early years saw him specialise in control systems and product development, which ultimately led him into commercial strategic roles – enabling businesses to thrive in the ever-changing energy and carbon landscape.

With hands-on experience from creating energy efficiency programs, to enabling on-site renewable energy generation, Anthony has a firm belief that you don’t have to sacrifice economics to be environmentally conscious. He’s actively involved in the commercialisation of circa £0.5billion (500MWp) of solar PV projects in the UK.

Alongside his passion for protecting the environment, he has a keen eye for developing excellence in people, as well as rewarding accordingly to provide a sustainable business environment, that in turn builds a better tomorrow.
