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.

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

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

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

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

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