UK Government Overhauls Nuclear Regulation
March 13, 2026
The UK government is undertaking a comprehensive reform of its nuclear regulatory framework to streamline processes, reduce costs, and accelerate project delivery for both civil and defence nuclear developments. This includes merging the Office for Nuclear Regulation (ONR) and Defence Nuclear Safety Regulator (DNSR), simplifying planning and environmental assessments, and establishing a new Nuclear Commission to enhance regulatory coordination. These reforms aim to support major projects such as Hinkley Point C, Sizewell C, and the development of small modular reactors (SMRs) like those planned at Wylfa, with implementation expected between 2026 and 2028.
- Why this matters: Procurement professionals should anticipate changes in regulatory requirements and processes that could impact contract timelines, compliance obligations, and project risk management for nuclear infrastructure projects.
- The consolidation of regulatory bodies and streamlined assessments may reduce administrative burdens and accelerate procurement cycles for contractors and suppliers.
- Companies involved in nuclear construction, engineering, and regulatory consulting should evaluate how these reforms affect bidding strategies and contract execution.
- The government's commitment to supporting large-scale nuclear projects signals sustained investment opportunities in the UK nuclear sector over the coming years.
To meet domestic energy requirements over the coming decades, accelerating the UKβs ability to generate safe, low carbon and sustainable electricity from nuclear energy sources is essential.

We need to go further and faster to build the clean energy we need to get off volatile fossil fuel markets and deliver energy security for our country.
— Ed Miliband
This ambitious programme of nuclear regulatory reform is the most important thing we can do to cut deployment times and costs, and rebuild the backbone of our energy security.
