If you're trying to hire in the nuclear sector right now, you already know the answer: they're like gold dust.
The UK is in the middle of the biggest nuclear investment push in a generation. Hinkley Point C is approaching peak construction. Sizewell C has the green light and is gearing up. Sellafield is spending billions on decommissioning. Rolls-Royce is pushing ahead with Small Modular Reactors. And down in Barrow, the submarine programme is scaling up fast.
All of that is brilliant news for the industry. But it creates one very big headache — everyone needs the same people, and there simply aren't enough to go around.
The Nuclear Skills Strategy Group puts the gap at over 40,000 workers needed by 2030. On top of that, roughly a third of the current nuclear workforce is over 50 and heading towards retirement. It's not a future problem. It's happening right now.
So Which Roles Are Hardest to Fill?
We talk to nuclear hiring managers every single day, and we hear the same frustrations coming up again and again. Some roles have been tough to fill for years. Others are becoming harder as new programmes ramp up. Here's what we're seeing across the market:
Nuclear Safety Case Engineers and Authors
This is probably the single hardest discipline to recruit in the entire UK nuclear sector. Every project — whether it's a new build, an operational plant, or a decommissioning site — needs safety cases approved by the Office for Nuclear Regulation. The catch? It takes years to train a competent safety case author, and the talent pool is painfully small. With SZC licensing work, Rolls-Royce SMR's regulatory submissions, and Sellafield all needing support at the same time, demand is through the roof.
Expect to pay £450–£700 a day for contract, or £55k–£85k permanent. And even then, you'll be competing hard.
Project and Programme Managers
Not just any project managers — nuclear project managers. There's a world of difference. Clients need people who understand nuclear governance, ONR interfaces, and the very specific way projects are delivered in this sector. A strong PM from construction or oil and gas can transition, but it takes time. The ones who already have nuclear delivery experience? They can practically name their price.
Contract rates run from £500 to £800 a day. Permanent packages sit between £65k and £100k+.
Mechanical and Electrical Engineers
The bread and butter of any nuclear programme, whether you're building, operating, or tearing down. HPC alone needs thousands. Sellafield has a constant appetite. SZC is ramping up design work. The submarine programme needs them too. And here's the bottleneck that makes it even worse — many of these roles require SC or DV security clearance, which instantly shrinks the available pool.
Contract rates of £400-£700 a day. Permanent salaries of £45k–£80k.
Radiation Protection Advisers and Health Physicists
RPAs are a legal requirement on every nuclear licensed site. Full stop. You can't operate without them. The qualified pool is small, regulated through the RPA 2000 register, and getting smaller as experienced professionals retire. Every site in the country is fishing in the same pond.
Rates of £400–£600 a day for an RPA on a contract or £60k - £90k permanent and £250 - £400 a day for Heath Physicists on a contract, or £50k–£75k on the permanent side.
Commissioning Engineers
Here's one that's getting more urgent by the month. As HPC edges closer to hot commissioning — expected from around 2027 — the teams need to be in place well ahead of time. The problem? Very few engineers in the UK have EPR or PWR commissioning experience. EDF is already looking internationally. Sellafield's new facilities are adding to the demand.
Heavily contract-weighted at around 75% of roles. Day rates of £400–£600.
Control and Instrumentation Engineers
C&I engineers are critical for reactor protection systems, distributed control systems, and the increasingly complex overlap with cybersecurity. New build, submarines, and SMR design all need them. It's a niche discipline and the nuclear sector is competing with defence and wider energy for the same candidates.
Contract rates of £380–£580 a day. Permanent salaries of £45k–£75k.
QA/QC Engineers (Nuclear Grade)
Nuclear quality assurance isn't like QA anywhere else. At HPC, engineers need to work to French RCC-M codes and ASME standards. Every weld, every concrete pour, every component installation needs rigorous QA oversight. Finding people with nuclear-grade QA experience — especially those familiar with EPR-specific standards — is a constant challenge.
Contract rates of £300–£450 a day. Permanent salaries of £38k–£55k.
Decommissioning and Waste Management Specialists
Sellafield is the largest decommissioning programme in Europe, spending over £2 billion a year. Add in Magnox sites, Dounreay, and the advancing Geological Disposal Facility programme, and there's a huge and growing need for people with hands-on decommissioning, waste characterisation, and retrieval experience. This is only going to get bigger.
A roughly even split between contract and permanent. Day rates of £350–£550.
Nuclear Security and Cybersecurity Specialists
The ONR's increasing focus on cyber resilience at nuclear sites has created a whole new category of demand. The AUKUS programme has elevated security requirements even further. The trouble is, nuclear isn't the only sector chasing these people — defence, finance, and tech are all competing for the same skillset. Candidates who combine cyber expertise with nuclear sector understanding are exceptionally rare.
Permanent salaries of £50k–£120k. Contract rates of £500–£800 a day.
Reactor Physicists and Nuclear Engineers
At the more specialist end, reactor physicists and core nuclear engineers remain perennially difficult to source. These are roles that typically require postgraduate qualifications and years of hands-on experience. With new build, SMR development, and the submarine programme all active, the demand is there — but the pipeline from universities isn't keeping up.
Why This Matters — And What We Do About It
Here's the honest truth: if you're posting a job advert for a nuclear safety case author or a DV-cleared commissioning engineer and waiting for applications to roll in, you're going to be waiting a long time. The best candidates in this market aren't scrolling job boards. They're already working. They're busy. And they're being approached by multiple recruiters every week.
That's where having the right recruitment partner makes a real difference.
At Scantec, nuclear recruitment isn't a sideline — it's one of our core specialisms, and has been for over twenty years. Here's what that actually means in practice:
We know the sector inside out. Our consultants understand the difference between an RPA and a SQEP assessor. We know why your commissioning engineer needs EPR experience rather than AGR. We don't waste your time with candidates who look good on paper but don't have the right background.
We have the network. Over two decades of dedicated nuclear recruitment, we've built relationships with thousands of nuclear professionals across the UK. Many of them are passive candidates — not actively looking — but they pick up the phone when we call because they know us and trust us.
We cover the full lifecycle. New build, operations, decommissioning, waste management, submarine programmes, SMR development — we recruit across all of it. Whatever your programme, we understand what you need.
We handle contract and permanent. The nuclear market needs both, and we deliver both. Quick mobilisation for project peaks. Long-term hires who'll grow with your organisation. Our payroll and compliance infrastructure makes it seamless.
We understand security clearance. SC, DV, BPSS — we know the timelines, the limitations, and the premium that pre-cleared candidates command. We identify clearance status early so there are no surprises down the line.
The Market Isn't Getting Easier
Let's be blunt: the competition for scarce nuclear skills is only going to intensify over the next decade. Programmes are overlapping. The retirement wave is accelerating. And cross-sector competition from defence, renewables, and oil and gas decommissioning means the same engineers are being pulled in every direction.
The organisations that secure the right talent partners now are the ones that will deliver their programmes on time. We'd like that partner to be us.
