Energy M&A

Back to Energy & Climate Change

CMS has the pre-eminent Energy M&A group in the UK, Advising financial investors, strategic investors, utilities and developers on high-profile, high-value, complex and first-of-a-kind M&A transactions across the energy sector.

CMS’ Energy M&A group particularly adds value when M&A transactions involve complex and/or cutting-edge issues that require the deepest sector knowledge.  This includes revenue stream support mechanisms, commercial and trading arrangements, licensing issues, industry code requirements and other regulatory issues, for both in-development and operational assets.
