Originally named, Great British Nuclear, Great British Energy - Nuclear is an arm’s length body of the Department for Energy Security and Net Zero, dedicated to supporting the development and deployment of new nuclear technologies in Great Britain. We play a crucial role in advancing nuclear new build, ensuring the UK’s energy security and achieving net-zero carbon emissions. Great British Energy - Nuclear focuses on fostering innovation, facilitating investment, and coordinating efforts across the nuclear industry to build a resilient and sustainable energy future.
Great British Energy - Nuclear’s first step was to start the technology selection process for Small Modular Reactors (SMRs) in 2023. 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. In June 2025, Great British Energy - Nuclear announced that Rolls-Royce SMR had been selected as the preferred bidder to build the UK’s first SMRs, following a technology selection process that began in 2023.
Great British Energy - Nuclear is aiming to deliver fast, based on a supportive and collaborative culture which values equality and diversity and creates an inclusive workplace.
The Environment and Sustainability Lead will lead the development, implementation and continual improvement of environmental and sustainability arrangements across the SMR programme, ensuring robust environmental governance, compliance and sustainable delivery principles are embedded across programme development, design, delivery planning and future site activities. The role will provide visible leadership and specialist advice in support of a first-of-a-kind UK SMR project.
Working across programme, technical, commercial, delivery and assurance teams, the postholder will ensure environmental protection, sustainability requirements and net zero considerations are integrated into governance, decision-making, contractor management and programme controls. The role will support the Head of Health, Safety, Environment and Sustainability in driving a proactive environmental culture, maintaining compliance with legislation and standards, and promoting practical, proportionate and innovative solutions.
Please note, this role will require travel to the Warrington Office 3 days a week.
