Commercial Manager

Great British Energy-Nuclear (GBE-N) is a new government arm's length body supporting the delivery of Britain's energy security and net zero, making sure that we can power Britain from Britain sustainably. It has been set up to turn nuclear ambition into reality.

GBE-N's first step was to start the technology selection process for Small Modular Reactors (SMRs). SMRs can potentially be quicker to deploy and less expensive to build than traditional nuclear power plants because they are smaller, have factory based modular manufacturing, and more flexible deployment options.

GBE-N is aiming to deliver fast, based on a supportive and collaborative culture which values equality and diversity and creates an inclusive workplace. It draws on deep nuclear expertise - its Executive Committee has over 100 years of nuclear experience in this country and abroad. And it can unlock billions of pounds of private and public investment from design to operation, helping to get sites ready for development, and working to grow manufacturing capacity and skills capability.

Our activities will be driven by our values, which are:

Trust - We prioritise safety, we act responsibly and with integrity.

Collaborative - We work as a team; we value diversity and expertise.

Challenge - We are curious and courageous in the way we think and act.

Care - We are thoughtful, inclusive and respectful of others.

Drive - We get things done and we make a difference.
