SERO
James is the Founder and CEO of Sero, a purpose-led company accelerating the transition to Net Zero in the social housing sector. With a strong foundation in engineering and renewable energy, James combines deep technical expertise with a passion for innovation and scalable solutions.
Driven by the urgent need to decarbonise homes, James leads Sero in developing forward-thinking models that make large-scale retrofit both financially viable and socially beneficial. Under his leadership, Sero introduced the groundbreaking Energy as a Service model—first implemented in the Penderi Energy Project, one of the UK’s largest retrofit initiatives. This model addresses the funding challenges faced by landlords, while simultaneously lowering energy bills for residents, improving housing quality, and cutting carbon emissions.
James is committed to reshaping how we fund and deliver sustainable housing, ensuring that the path to Net Zero is inclusive, practical, and impactful.
