Infrastructure and Energy (I&E)

We advise on the full range of matters for Infrastructure & Energy (I&E) clients. Our advice often spans the project life cycle and includes formation of joint ventures and structuring of shareholder arrangements, as well as other M&A aspects (including asset level DD); all financing, hedging and credit support arrangements; offtake, power trading and energy services arrangements; construction and O&M arrangements; real estate and consents; regulatory advice; and dispute resolution.

We have extensive experience advising on I&E deals across the world, including transactions in renewables, oil and gas, nuclear, water and waste, mining, airports, rail, stadia, telecommunications and other networks.

We are frequently instructed on matters of key significance to our clients, which means that we focus on the most high-value, complex deals in the sector, requiring innovative thinking and highly creative and non-standardised advice.

We received a commendation for Energy & Renewables in The Times Best Law Firms 2020, and were shortlisted for the 2019 Energy and Infrastructure Team of the Year in The British Legal Awards and Energy & Infrastructure Projects Team of the Year in The Lawyer Awards.

Our work with Ørsted won us the European Wind Deal of the Year at the IJL Global (Project Finance and Infrastructure) Awards and the Europe Renewables Deal of the Year at the Project Finance International Awards, and we were shortlisted for Innovation in legal expertise: Managing complexity and scale in the FT Innovative Lawyers Awards 2018.
