UK moves to accelerate nuclear projects through sweeping regulatory reform

The UK government has announced plans to overhaul the regulatory framework governing nuclear power projects, aiming to shorten development timelines and reduce costs while maintaining safety and environmental protections.
The reforms follow the publication of the Nuclear Regulatory Taskforce report in November 2025, which called for a fundamental reset in the way nuclear projects are regulated and approved in the UK. The taskforce, led by former Office of Fair Trading chief executive John Fingleton, outlined 47 recommendations designed to streamline oversight and speed up the delivery of new nuclear infrastructure.
Officials say the full set of reforms is expected to be implemented by the end of 2027, subject to legislative processes. The government argues that improving the regulatory system will be critical if the UK is to expand nuclear generation as part of its long term energy strategy.
The Department for Energy Security and Net Zero said the changes aim to create a more proportionate and evidence based regulatory environment focused on real risk. Ministers believe this approach will help deliver nuclear projects more efficiently without weakening safety standards.
Energy Secretary Ed Miliband said the urgency of the transition away from fossil fuels had been reinforced by geopolitical instability and volatile global energy markets.
The government views nuclear power as a central pillar of its plan to strengthen energy security while supporting the shift to low carbon electricity generation.
Streamlining nuclear regulation and project approvals
One of the most significant elements of the reform programme is the creation of a single lead regulator for nuclear projects. This change is designed to simplify how developers interact with regulators and reduce overlapping responsibilities across agencies.
The Office for Nuclear Regulation has already been designated as the interim lead regulator while the government works toward establishing a new Commission for Nuclear Regulation.
Supporters of the reform argue that complex regulatory structures have historically contributed to delays and rising costs in major infrastructure projects. By consolidating oversight and clarifying decision making processes, policymakers hope to bring greater predictability to the development pipeline.
Chancellor Rachel Reeves has also urged organisations across the nuclear sector to reassess how they manage risk. In an open letter to industry leaders and regulators, she called for a cultural shift that prioritises proportionate decision making and removes unnecessary complexity from regulatory procedures.
Reeves asked organisations to review internal processes and identify areas where delays, duplication or uncertainty could be reduced. She also emphasised the importance of clearer timelines and stronger accountability in project approvals.
Industry groups have broadly welcomed the government’s direction. Tom Greatrex, chief executive of the Nuclear Industry Association, said regulatory reform was essential if the UK is to accelerate nuclear deployment and rebuild energy resilience.
The government believes that improving the efficiency of nuclear approvals could also influence how other major infrastructure projects are regulated in the future, including potential reforms to judicial review processes.
Investment in nuclear skills and research
Alongside regulatory reform, the government is investing in research and workforce development to strengthen the UK’s nuclear capability.
More than 500 doctoral students will be trained in nuclear related disciplines across universities over four annual intakes. The initiative will effectively quadruple the current number of nuclear PhD candidates entering the sector.
The programme is supported by £65.6 million in funding from UK Research and Innovation, which will be matched by industry partners. Research projects will focus on areas such as advanced reactor components, nuclear fuels, waste management and materials science.
Universities including Bangor University, the University of Glasgow and Imperial College London will host research programmes linked to the initiative.
Officials say the investment is intended to ensure the UK maintains a strong pipeline of technical expertise as it expands both its civil nuclear sector and its defence capabilities.
The research programmes will also support emerging technologies such as advanced nuclear reactors and small modular reactors, which are expected to play a growing role in the future energy system.
Nuclear energy and the UK’s long term energy strategy
The reform agenda arrives at a time when the UK is seeking to accelerate the deployment of low carbon energy infrastructure.
Large scale projects such as Hinkley Point C remain central to the country’s nuclear expansion plans, while new developments including the proposed small modular reactor programme at Wylfa in Anglesey are expected to shape the next phase of the sector.
Simon Roddy, chief executive of Great British Energy Nuclear, said a more predictable regulatory framework would help translate government ambitions into real world progress.
Industry leaders have repeatedly argued that lengthy regulatory processes and complex approval structures have slowed the pace of nuclear construction in the past. Addressing these barriers, they say, will be essential if the UK is to deliver new capacity on schedule.
At the same time, regulators stress that safety and security will remain the foundation of the nuclear oversight system.
Mike Finnerty, chief nuclear inspector and chief executive of the Office for Nuclear Regulation, said the organisation welcomed the government’s acceptance of the taskforce recommendations. He added that regulators would work closely with industry and policymakers to ensure projects can move forward efficiently while maintaining strict safety standards.
With nuclear power expected to play a key role in meeting the UK’s climate and energy security goals, the success of the regulatory reforms will likely shape the pace of new nuclear development over the coming decade.
