We are trusted independent experts

Independent experts, trusted for our unrivalled insight to help you succeed in the net zero transition

Cornwall Insight is an independent energy research, analytics and consulting firm. We are widely recognised for our objectivity and commitment to facilitating positive market and policy change, whilst also advising customers on how to navigate and comply with energy market dynamics, rules and regulations. 

We have been trading since 2005 and since 2017 investment from carefully selected capital providers has enabled the company to pursue these activities more effectively than would otherwise have been possible. This has brought more varied and better insights for our customers, allowed us to expand into new markets and sectors,  as well as enabling great careers for our people. We are currently majority-owned by Bowmark Capital, with employees also holding a significant minority shareholding

None of Cornwall Insight, its employees or Bowmark Capital engage in energy trading or energy supply.
