On 13 May 2026, the King's Speech confirmed that the government will introduce a Nuclear Regulation Bill to legislate the recommendations of the Fingleton Review. It sits alongside an Energy Independence Bill in the 2026 to 2027 parliamentary session.

The bills were framed as a direct response to global volatility. The King said energy independence "must be a long-term goal of national security" and that increased production of clean British energy is essential to economic security.

For engineers, technicians and the recruiters who support them, the Nuclear Regulation Bill is the substantive change. It will legislate 47 recommendations from the independent Nuclear Regulatory Taskforce led by John Fingleton CBE, all of which the government has accepted in principle.
 

What the Nuclear Regulation Bill changes

The Fingleton Review, published on 24 November 2025, concluded that the UK's nuclear regulatory system was overly complex and slow. The government's response, "Building Our Nuclear Nation", commits to having all reforms implemented by the end of 2027.

The headline structural changes include:

• A new Commission on Nuclear Regulation, fully functioning by Summer 2028, with the power to resolve disagreements between regulators
• The Office for Nuclear Regulation (ONR) designated as the lead regulator for significant multi-regulator projects, starting March 2026
• A merger of the ONR with the Defence Nuclear Safety Regulator (DNSR), beginning Autumn 2026 and complete by end of 2028
• Environmental Outcomes Reports replacing Environmental Impact Assessments by December 2027
• A legislative definition of "grossly disproportionate" to constrain how the ALARP principle is applied
• Reforms to the nuclear siting framework and the justification process, opening the door to Small Modular Reactors (SMRs) and Advanced Modular Reactors (AMRs) at a wider range of locations

Many of these changes happen by ministerial direction and operational reform, not by waiting for the bill itself to receive Royal Assent. ONR becoming lead regulator from March 2026 is already in motion.
 

Industry reaction

The reaction from major engineering consultancies, trade bodies and unions has been broadly supportive.

"The intention to act on the Fingleton recommendations to streamline the construction of nuclear power plants is the most significant reset of the UK's nuclear regulatory system in more than 20 years. These reforms have the potential to materially reduce both the cost and delivery timeline of new nuclear."

Claudio Tassistro, Managing Director of Energy UK and Europe, Mott MacDonald, in New Civil Engineer

The Nuclear Industry Association, which represents most of the UK's civil nuclear supply chain, was equally direct.

"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."

Tom Greatrex, Chief Executive, Nuclear Industry Association

The Office for Nuclear Regulation has confirmed it is prepared to deliver the changes.

"ONR is ready to implement recommendations that remove any unnecessary burden from the regulatory framework, while maintaining rigorous safety standards."

Mike Finnerty, CEO and Chief Nuclear Inspector, Office for Nuclear Regulation

The pipeline these reforms accelerate

Alongside this civil pipeline, the Defence Nuclear Enterprise is in a sustained expansion. The AUKUS submarine programme, the Dreadnought Class build at Barrow, the Atomic Weapons Establishment's Future Materials Campus at Aldermaston, and the HMNB Clyde redevelopment are all moving forward concurrently. Sheffield Forgemasters, the UK's only forge capable of producing reactor-grade castings, is in the middle of a £1.3 billion modernisation that secures over 700 jobs.
 

What this means for engineering and technical talent

The Spending Review 2025 committed around £30 billion to civil nuclear, including £14.2 billion for Sizewell C, £2.6 billion for the Rolls-Royce SMR programme, more than £2.5 billion for fusion, and £13.9 billion for the Nuclear Decommissioning Authority. The defence side adds £6 billion for the submarine industrial base and £15 billion for the sovereign warhead programme.

The headline workforce numbers are stark. The Nuclear Skills Plan targets 40,000 additional civil nuclear workers by 2030, growing the sector from 83,000 to 123,000. The Defence Nuclear Enterprise is set to grow from 47,600 jobs to 65,000 over the same period, with 22,000 apprenticeships and 9,000 graduate roles by 2034 to 2035. Average salaries in defence nuclear are now around £45,500, approximately 20% above the UK average.

The most in-demand disciplines fall into clear groups:

• Safety case professionals and nuclear engineers
• Civil, mechanical, electrical and instrumentation and control engineers
• Project managers, project controls and commercial managers
• Welders, fitters and skilled trades, particularly for pressure vessels and reactor internals
• SC and DV-cleared professionals for defence nuclear roles

As civil and defence nuclear regulation come closer together, suitably qualified and experienced persons (SQEPs) will move more easily between the two. Hiring managers who can present civil and defence opportunities side by side will have an advantage in attracting cleared and clearable talent.
 

Regional hotspots

Nuclear engineering hiring is now concentrated in a defined set of regional clusters:

• Suffolk for Sizewell C
• Somerset for Hinkley Point C
• Anglesey for the Rolls-Royce SMR at Wylfa
• Sheffield and South Yorkshire for forgings and the planned Rolls-Royce SMR module factory
• Cumbria for submarine build at Barrow and decommissioning at Sellafield
• Derby for Rolls-Royce Submarines and Rolls-Royce SMR
• Plymouth for Babcock Devonport
• Glasgow and Govan for HMNB Clyde
• Aldermaston for the AWE Future Materials Campus
• Hartlepool and Teesside for the X-energy AMR programme
• Nottinghamshire for both the Cottam SMR-300 project and the STEP fusion plant at West Burton

For mid-career professionals, the overlap with offshore wind and grid infrastructure clusters in Teesside, the Humber, East Anglia, Aberdeen and Milford Haven is also worth tracking, particularly for project controls, civils and high-voltage electrical roles.
 

The Energy Independence Bill in brief

The Energy Independence Bill is the second piece of the King's Speech that matters for technical recruitment. It will scale up homegrown renewable energy, reform grid infrastructure regulation, streamline land access and consents for renewables, and expand Ofgem's remit to cover third-party intermediaries such as energy brokers.

It follows a record Allocation Round 7 in early 2026, which awarded 8.4 GW of offshore wind plus 6.2 GW of onshore wind, solar and tidal. The Clean Industry Bonus has mobilised over £3.4 billion of private supply-chain investment, supporting up to 7,000 jobs across factories, ports and manufacturing.

Engineering employers in offshore wind, solar, hydrogen and grid infrastructure should expect the bill to materially shorten consenting timelines, with knock-on effects on engineering design and project delivery hiring.
 

Millbank's perspective

For engineering employers and the engineers they want to hire, the message from 13 May is simple. The legal scaffolding for a faster, larger UK nuclear and clean energy programme is now being put in place. The pipeline of projects is real and contracted. The workforce numbers required to deliver it are public and well documented.

The opportunity is to move with the implementation calendar, not the Royal Assent date. Many of the most important changes are operational and begin in 2026.
