Jeremy Nicholls is the Chairman of SIAA and the Chief Executive of the Social Return on Investment (SROI) Network since 2008.

He started his working life as a chartered accountant in the  UK. He has also lived and worked in Tanzania, Liberia and briefly Nicaragua. His work has increasingly focused on understanding and managing the value of the impact of organisation’s activities. He set up the Cat’s Pyjamas running events to promote the value of social enterprise and shortly after started working on the development of SROI. He wrote ‘There is no business like Social Business’ with Liam Black and co-wrote the UK Government supported ‘Guide to SROI’.

In addition to being a trustee of SIAA, he is a director of the FRC Group - a social business based in Liverpool - and a director of Social Evaluator, an online platform for the analysis of social returns.
