Stephenson Harwood advises on Sizewell C development

Energy Transition | 22/08/2025

Law firm Stephenson Harwood LLP has advised on the Sizewell C power plant project, which has seen the UK Government commit over £14 billion to its development.

The Sizewell C nuclear power plant is set to provide 10,000 people with employment at its peak of construction. The National Wealth Fund – the government's principal investor and policy bank, is providing the majority of the debt finance.

Stephenson Harwood advised on employment, pensions, employee incentives, data protection regulations, technology contracts, marine and harbour works, and civils contracts.

The cross-practice team was led by Head of Employment and Partner Paul Reeves, with support from Partners Richard Freedman (employment), Stephen Richards (pensions), Nicholas Stretch (tax and incentives), Jonathan Cripps and Graeme Barton (projects, energy and infrastructure), Simon Bollans and Jonathan Howie (technology), Katie Hewson (data protection), and Alex Davis (marine).

Jonathan Cripps, Head of the energy transition sector group, said: “The energy transition is one of the defining challenges of our time, and nuclear projects like Sizewell C are a crucial part of the solution. By providing reliable, low-carbon power at scale, Sizewell C will help secure the UK’s energy future while supporting our net zero ambitions. We are proud to support this landmark project, which demonstrates how innovative financing and collaboration can drive progress towards a more sustainable energy system.”
