Our Energy & Climate Change team comprises individuals with deep sectoral knowledge who have helped shape the regulatory regime for electricity and gas in GB and across the world. We have a team fully devoted to the energy sector that is one of the largest in the UK and a recognised leader in the field. We are ranked in Band 1 for Energy in Legal 500.
We have been advising in the energy sector for over 25 years and been at the forefront of creating many of the innovative and ground-breaking elements of the industry structures and markets, including writing the various electricity codes. We have unrivalled knowledge of the sector-specific European and UK primary and secondary legislation.
The team regularly advises on interactions and matters with economic regulators and related bodies (such as Ofgem, Ofwat, the Utility Regulator in Northern Ireland, BEIS and the CMA). The team is recognised as a “go to” adviser for the sector in navigating industry and regulatory frameworks in the UK and across the world, with advisers who are steeped in an understanding of the legal, political and practical constraints faced by policy makers, regulators and the sectors they regulate.
CMS’ range of advice spans from helping clients in responding to policy consultations and has significant success in raising legal issues in a way that will encourage regulators and policy makers to take submissions into account and ultimately reconsider their positions all the way through to judicial review and CMA appeals. The team also regularly helps clients with correspondence with regulators, which can be particularly sensitive where these are in contemplation of a judicial review or regulatory appeal.
