Liam advises a wide range of clients, including debt and equity investors, joint venture partners, asset owners and operators, energy supply companies, corporate offtakers, and asset optimisers, supporting them on transaction structure, management, and execution, due diligence, and contract development.

Liam has previous in-house experience from secondments at an oil and gas supermajor acting on offshore ventures, one of the ‘Big Six’ power companies acting on the development of renewable projects, and for the trading and marketing arm of a European oil and gas company advising on energy and emissions trading.
