Terra Firma Energy – 12 June 2025

A major milestone for the UK energy sector has been announced as the government confirms a £14.2 billion investment in Sizewell C — a next-generation nuclear power station in Suffolk. The project is set to create 10,000 new jobs, including 1,500 apprenticeships, revitalising the UK’s nuclear capabilities and boosting energy security for generations to come.

This landmark investment is part of a broader national strategy to transition to clean, homegrown energy, reduce reliance on fossil fuels, and stimulate long-term economic growth.

Powering the UK with Clean Energy

Once operational, Sizewell C will generate enough low-carbon electricity to power around six million homes, delivering a significant contribution to the UK’s net zero goals.

The construction phase alone will inject momentum into the national economy, with 70% of contracts expected to go to UK suppliers — benefitting over 3,500 British businesses across sectors including construction, manufacturing, engineering, and hospitality.

A Boost for Skills, Jobs, and Regional Growth

The government has already enabled over £330 million in contracts with local companies, and the project will bring thousands of well-paid jobs to the region, many in collaboration with trade unions such as GMB, Unite and Prospect.

Importantly, 1,500 apprenticeships will ensure a pipeline of talent is developed, strengthening the UK’s long-term nuclear expertise and supporting careers in skilled trades and high-value roles.

A New Era for Nuclear Energy

This announcement marks the start of the UK’s most ambitious nuclear programme in a generation. Alongside Sizewell C, the government is backing Small Modular Reactors (SMRs) and investing over £2.5 billion in fusion energy R&D, including development of the STEP (Spherical Tokamak for Energy Production) prototype in Nottinghamshire.

Combined with the progress at Hinkley Point C and reforms to planning laws, these steps demonstrate a clear commitment to a future powered by clean, secure, British energy.

National Security and Economic Resilience

Beyond clean energy, the government is also investing in the defence nuclear sector. A further £4 billion over the next decade will support the redevelopment of the Plymouth naval base and HMNB Clyde, while £6 billion will expand capacity in submarine manufacturing hubs like BAE Systems (Barrow) and Rolls-Royce (Derby).

This integrated civil and defence nuclear strategy is not only critical to national security — it also brings economic opportunity, skilled jobs, and investment to communities across the UK.

Industry Reaction

Julia Pyke and Nigel Cann, Joint Managing Directors, Sizewell C:
“Today marks the start of an exciting new chapter for Sizewell C — the UK’s first British-owned nuclear plant in over 30 years. We’re proud to lead a project that will create thousands of jobs and secure a clean energy future.”

Rachel Reeves, Chancellor of the Exchequer:
“We are creating thousands of jobs, kickstarting economic growth, and delivering the biggest nuclear building programme in a generation.”

Ed Miliband, Secretary of State for Energy Security and Net Zero:
“We are investing in a golden age of clean energy. New nuclear is vital for energy security, lower bills, and climate action.”

Tom Greatrex, CEO, Nuclear Industry Association:
“This programme will bring jobs, growth, and energy stability. It’s a huge moment for the UK’s nuclear future.”

A Turning Point for British Infrastructure

At Terra Firma, we believe infrastructure is about more than bricks and steel — it’s about securing a sustainable, prosperous future. The Sizewell C announcement demonstrates how bold, strategic investment in clean energy can transform our national capabilities, drive regional opportunity, and deliver tangible benefits to people and the planet.

We welcome the government’s commitment and look forward to the opportunities this historic investment will unlock for UK industries, workers, and communities.
