Why Join Us

Be part of a nationally significant project helping to deliver the UK’s clean energy future.

Work alongside industry-leading experts on one of the country’s largest infrastructure programmes.

Enjoy a competitive reward package, outstanding benefits and the opportunity to make a lasting impact on a project of national importance.

Why Join Us?

For more than 60 years, nuclear power stations in the UK have been quietly keeping Britain fuelled with massive amounts of home‑grown energy.

Our teams up and down the country are proudly continuing to serve the nation – but they also have an eye on the future.

EDF is leading the UK's nuclear renaissance with the construction of a new nuclear power station at Hinkley Point C and plans for a new power station at Sizewell C in Suffolk.

Nuclear power is the most reliable, low-carbon energy source currently available to the UK. EDF is playing a key role in the development of nuclear sites, while Hinkley Point C will provide low-carbon electricity to meet 7% of the UK demand. The project is already making a positive impact on the local and national economy as well as boosting skills and education.

We’re not just building new nuclear power stations. We’re developing careers, upskilling generations and creating thousands of employment and apprenticeship opportunities across a variety of skills areas.

It takes a special kind of person to work in the nuclear energy industry and although we have thousands of them there’s always a need for more.

Our industry has a mind-boggling range of opportunities and more jobs, and in more places, than you might think. But it’s also an industry which is changing.

We’re a responsible business and proud to be Britain’s biggest generator of zero carbon electricity. With size, age and experience, we believe we can do even more.
