History
JBA Group was founded in 1995 by Jeremy Benn, who continues to serve as Group Executive Chair. From its origins as a specialist consultancy, the group expanded into a family of companies covering environmental consultancy, engineering, risk management and catastrophe modelling. Over nearly three decades it has built a reputation as one of the world's leading specialists in flood risk, environmental engineering and climate adaptation. A defining characteristic of the group is its employee-owned structure, which it says gives it the freedom to make its own choices, take responsibility for its decisions and maintain a long-term, sustainable vision. This independence has allowed JBA Group to pursue major studies for national governments, financial institutions, insurers and international bodies including the World Bank, the European Investment Bank, Defra and the Environment Agency. The group has also committed to environmental goals of its own, including a target to reach Net Zero by 2040. It provides funding and technical support to charitable and environmental initiatives. Today JBA Group operates globally from its UK base, helping clients build resilience to flood and environmental risk in a changing climate.
