First Sizewell C Sustainability Report shows how big infrastructure can build a legacy for people, communities, and the environment

Sizewell C has published its first Annual Sustainability Report, setting out how the UK’s newest nuclear power station – the first majority British-owned plant in decades – will deliver lasting benefits for people, communities, and nature.

Almost two years into construction, the project now employs nearly 2,000 people on site and is driving investment across the UK. More than 400 British suppliers have secured contracts worth £2.8 billion, including £126 million awarded locally in Suffolk.

The report shows Sizewell C is on track to:

• Support tens of thousands of jobs across the UK
• Create 1,500 apprenticeships
• Deliver 70% of construction spend to UK businesses
• Increase local biodiversity by 19%

While construction inevitably brings disruption, the report highlights Sizewell C’s determination to ensure the project gives back more than it takes, offering long-term opportunities for local people and future generations.

A central focus of the report is education and skills. Sizewell C is working with local education providers and a network of 12 schools across Suffolk to strengthen STEM learning and introduce new programmes in performing arts that build self-confidence, communication, and aspiration. This approach will soon extend to schools in Lowestoft and Ipswich, helping connect even more young people to the possibilities of science and engineering.

To date, the project has:

• Delivered more than 400 school and community events, engaging over 16,000 students
• Supported career guidance, workshops, and apprenticeships across the region
• Partnered with colleges and universities to build a pipeline of future talent
• Invested in a new college on the coast to give local young people a path into high-value, low-carbon careers
  Sizewell C is also setting new standards for equality in the nuclear sector, with 42% of its client workforce and 64% of its executive team now women, both exceeding industry benchmarks. Partnerships with Inclusion and Diversity in Nuclear, and initiatives such as the Forces Support Network and Combat2Coffee, are helping create a workplace that reflects the communities it serves.

The report also highlights Sizewell C’s environmental work, including the restoration of 170 hectares of land into three new nature reserves. The organisation is committed to going above and beyond its habitat compensation requirements, targeting a significant 19% net gain in biodiversity, almost double the required 10% that is now required for developments in the UK.

Publication of the Sustainability Report today alongside the Annual Report and Accounts follows the Final Investment Decision taken by the UK Government in the summer giving the project the go-ahead.

Welcoming the report, joint Managing Directors Julia Pyke and Nigel Cann said: “This first Annual Sustainability Report is a landmark for Sizewell C and shows how big infrastructure can deliver lasting social benefits. We are already creating thousands of jobs, supporting local communities, and protecting Suffolk’s environment. While construction does bring temporary disruption, we are determined to ensure that our project delivers lasting change for the better for East Suffolk. Sizewell C will power six million homes with clean energy for 60 years, but its legacy will be measured just as much in the opportunities and benefits it brings to people, communities, and nature.”
