The Department for Energy Security and Net Zero (DESNZ) has published its response to the Nuclear Regulatory Review 2025, accepting the findings of the independent Nuclear Regulatory Taskforce led by John Fingleton and setting out a programme of reforms to overhaul nuclear regulation, planning and delivery. The government will implement all recommendations by the end of 2027, introducing a more proportionate, risk-based regulatory system to reduce delays and costs while maintaining safety and environmental protections. The reforms aim to accelerate civil and defence nuclear projects, strengthen energy security, support economic growth, and reduce reliance on fossil fuels. Central measures include restructuring regulation by strengthening and expanding the role of the Office for Nuclear Regulation, merging it with the Defence Nuclear Safety Regulator, establishing a Nuclear Commission to resolve disputes, and introducing a lead regulator model to improve coordination and decision-making.
