Built for the scale and complexity of nuclear new build

Driven by the need for energy security and low-carbon power, projects such as Hinkley Point C and Sizewell C are now in large-scale construction, with thousands of workers already on-site. Alongside this, the next phase of the UK’s nuclear programme is already taking shape through STEP and small modular reactors like the Rolls-Royce SMR.

This creates a continuous pipeline of activity across projects, regions, and delivery phases.

 

One partner across every phase of a nuclear programme

 

Nuclear new build programmes place unique demands on workforce delivery. Civils, MEH, and commissioning phases each require different skill sets, often overlapping across the same timeframes and locations.

The workforce demand doesn’t stay static. It moves with the programme, and workforce planning becomes a live, ongoing challenge across multi-year projects within the UK nuclear supply chain.

Understanding this, our workforce model is built to respond to changing demand across the full nuclear lifecycle, supporting delivery as programmes scale and progress.

 

Compliance ingrained in nuclear workforce delivery

Security clearance, IR35, and audit requirements are ingrained in our operating model as part of the process, supporting consistent and compliant delivery across safety-critical environments at scale.

Embedded in local and national nuclear supply chains

Long-term regional presence supporting local labour and supply chains with established relationships across nuclear project ecosystems.

Nuclear construction workforce demand planning

Civil nuclear new build recruitment built for workforce demand planning, allowing teams to scale as requirements change across all phases of the nuclear lifecycle. This is underpinned by consistent delivery at volume, with over 600 permanent nuclear hires each year across projects ranging from £100m to £47bn.

Rullion wins at 2026 Alstom Supplier CSR Awards

Rullion wins at 2026 Alstom Supplier CSR Awards

Rullion has been independently recognised by Alstom, one of the UK and Ireland’s largest rail organisations, for its work in protecting the health and wellbeing of people across safety-critical infrastructure. At Alstom's Supplier Corporate Social Responsibility Awards, held during its Supplier Day, Rullion won the Improve Health and Wellbeing Award for Large Companies. The awards recognise suppliers delivering meaningful social value across Alstom’s UK and Ireland supply chain, with entries judged by the customer teams who work closely with them. In its assessment, Alstom highlighted Rullion’s strong focus on preventing work-related ill health through robust risk management, as well as its understanding that wellbeing initiatives only make a lasting difference when they are supported by the wider culture. The feedback also described the breadth of evidence submitted by Rullion, including activity linked to an Alstom-hosted Inspire session. Wellbeing that supports real working lives At Rullion, supporting wellbeing is built into how we deliver workforce solutions rather than bolted on as a separate campaign. Our focus is on spotting pressure early, before it affects someone’s health and their safety on site, or the continuity of a client’s project. That means giving people consistent support, whether they are a permanent employee or a contractor working on a short-term assignment. Across the business, this is supported by trained specialists, practical manager guidance, and clear routes into help when someone needs it. This includes Mental Health First Aiders, I-ACT practitioners, our Wellbeing Warriors network, and partnerships with organisations such as Able Futures and Help@hand. In rail and other safety-critical environments, early support can make a real difference. Fatigue, stress, travel pressures, working patterns, and fitness-for-work concerns all need to be understood before they become a risk on site. This sits alongside the compliance frameworks rail employers already rely on, including RISQS and Sentinel, where workforce readiness and safety are closely connected. By staying close to people and giving managers the tools to respond, Rullion helps protect individual wellbeing while supporting safer, more reliable project delivery for clients. For clients, this joined-up approach helps protect individual wellbeing while supporting safer, more reliable project delivery. Supporting contractors in safety-critical environments Contractors are central to the UK rail workforce, often deployed on time-sensitive projects where compliance and site readiness leave little room for disruption. Rullion's role goes beyond placing people into roles. Our teams stay close to contractors across their assignments, so concerns surface early rather than at the point they affect a shift or a milestone. This means regular contractor engagement, proactive fatigue management, and direct conversations about travel, working patterns, medical compliance, and fitness for work. When we identify a risk, we work with the client to resolve it before it lands on site. Keeping contractors well and engaged is better for the individual, but it also supports the smooth running of large-scale programmes. A workforce that feels supported is more likely to remain prepared and able to work safely in demanding environments. A partnership shaped by shared standards This recognition is especially meaningful because it comes from a long-standing customer relationship. Alstom sees how Rullion operates day to day, and this award reflects the experience of the teams who work alongside us. It is also the second time Rullion has been recognised at Alstom’s Supplier CSR Awards, following our previous win in the Driving Equal Opportunity Award for Large Companies category. Being recognised twice, across two different areas, reflects Rullion’s wider role as a workforce partner committed to opening up access to opportunity and supporting the wellbeing of people across the rail supply chain and wider critical infrastructure programmes. Alistair Haigh, Executive Director at Rullion, said: “Being recognised by Alstom is a proud moment for us. Across critical infrastructure, supporting people well is fundamental to delivering complex projects safely and successfully. It is not a nice-to-have. This award reflects the care our teams show every day, supporting clients and contractors to create safer, healthier working environments. We're grateful to Alstom for the recognition and proud of the partnership we've built together.” Continuing to build healthier, safer workforces Workforce support has to hold up on-site, across depots, project sites and live safety-critical operations. Continuing to invest in wellbeing means helping people feel looked after while giving clients more stable, resilient, and engaged workforces. We sustain that by: Providing early support when concerns are identified Maintaining regular engagement with employees and contractors throughout their assignments Equipping managers with the guidance and tools to support their teams effectively Working closely with clients to promote safe, healthy, and sustainable working environments This is not only a rail story. It is part of Rullion’s wider role as a workforce solutions provider for critical infrastructure. In these settings, a well-supported workforce helps large-scale programmes move safely and reliably, with the people they need in place.

Does Your Early Careers Strategy Hold Up Under Pressure?

Does Your Early Careers Strategy Hold Up Under Pressure?

Most early careers programmes are built to run. Fewer are built to respond. For organisations in nuclear, energy, water, utilities and rail, that distinction matters. A strong early careers strategy is not simply about filling entry-level roles. It is about building the skills base future projects will depend on. Across these critical infrastructure sectors, hiring is rarely straightforward. Talent pipelines take time to build, and role requirements can shift while a campaign is already live. When an early careers programme cannot adapt mid-campaign, the impact is not limited to one delayed hire or one missed intake. It can create capability gaps that take years to close. That is why agility matters. Not agility as speed for its own sake. Agility as the ability to make informed decisions when conditions change. It means reading the pipeline early enough to spot where candidates are dropping out, then adjusting the campaign before momentum is lost. Jump to: Why critical infrastructure hiring puts early careers strategy under pressure Employer branding affects how quickly your campaign can respond What responsiveness looks like inside the early careers pipeline Fixed supplier models can slow the decisions that matter Shared ownership gives the programme room to move What to ask before your next early careers campaign Why critical infrastructure hiring puts early careers strategy under pressure Early careers hiring in critical infrastructure rarely happens in neat, predictable conditions. Campaigns often have to move before every role specification is fully confirmed. Application volumes can be difficult to forecast, and stakeholder requirements may continue to evolve once activity is already underway. That creates a very different environment from a standard graduate campaign. These organisations are hiring into sectors with long-term workforce needs and specialist technical roles that graduates may not immediately understand. The work is essential, but the career paths are not always obvious from the outside. A graduate may understand the appeal of joining a major technology brand or consultancy much faster than they understand the breadth of opportunity inside a water utility, nuclear operator or rail infrastructure organisation. The pressure is rarely spread evenly across the campaign either. Early talent attraction may appear steady before assessment centres, offer stages, and hiring manager reviews create sudden spikes in activity. A programme planned around a consistent level of resource can quickly become stretched at the moments where pace and judgement matter most. For example: In nuclear early careers, hiring may need input from safety teams or site-based technical stakeholders before candidates can progress. In water utilities, regional hiring needs can make attraction more uneven, with some locations generating strong interest while others need more targeted support. Across critical infrastructure, those kinds of variables make a fixed campaign model difficult to rely on. The added challenge of building an early careers programme from scratch For organisations developing an early careers programme for the first time, those pressures arrive without the benefit of an established model. There may be no reliable historical volume data, no proven channel mix, and no clear benchmark for how candidates will move through the process. “That makes agility important from the beginning, not something that we add once the programme matures. The strategy needs enough structure to give the campaign direction but enough flexibility to respond when conditions change.” - Dan Crerand, Director of Talent & Skills Employer branding affects how quickly your campaign can respond Employer brand is often treated as a pre-campaign activity. Build the message, launch the campaign, and review performance at the end. Graduate employer brand has a direct effect on how much pressure an early careers programme has to absorb during the campaign. Organisations with strong graduate brand recognition arrive with a level of built-in momentum. Candidates already know who they are and understand the offer before the campaign reaches them. That recognition may come from campus activity, peer networks, or previous graduate recruitment campaigns. Employer branding for critical infrastructure organisations Many organisations in nuclear, water utilities, rail, energy and renewables do not have that same advantage at the graduate level. That does not mean the roles are less compelling. Often, the opposite is true. These sectors can offer graduates meaningful work with technical depth and visible impact. The challenge is that the proposition often needs more explanation. In graduate rail recruitment programmes, the range of roles available is often wider than candidates expect. Behind day-to-day operations of the railway sits a business that spans commercial, digital, engineering, project management, and sustainability roles. Across the energy sector, the employer brand challenge may be different again. Organisations need to show how graduate roles connect to grid resilience, decarbonisation, infrastructure investment, or the practical delivery of the energy transition, rather than relying on broad sustainability messaging. If the pipeline is not building in the right disciplines, locations or candidate groups, the early careers strategy has to respond while the campaign is still live. Before applications close, the team may need to change the message and redirect activity or remove friction from the application process. A campaign that only reviews employer branding strategy at the end will always be reacting too late. What responsiveness looks like inside the early careers pipeline Monitor the pipeline while there is still time to act A responsive early careers pipeline is monitored continuously. Not just at headline level, and not only at the point of attraction. The useful questions are more specific: Which disciplines are filling faster than expected? Which locations are under-supplied? Which candidate groups are entering the funnel but not progressing? Where is the process creating friction? Which stages are taking longer than planned? Where are hiring managers becoming a bottleneck? For early careers hiring in rail, energy, nuclear and water utilities, those questions need to be asked early enough to influence the outcome. Knowing there is a shortfall after the campaign closes may help the next intake. Knowing it mid-campaign can protect the current one. Track diversity through every stage Attraction data only tells part of the story; diversity needs the same level of attention. A diversity recruitment strategy has to track candidate movement through every stage of the funnel, from initial engagement through to final acceptance. If female candidates, for example, are entering the early careers pipeline but dropping before completion, that points to a specific issue in the process. It could be: Job description language Website content Assessment communications Confidence levels Perceived fit or the way the opportunity has been framed Dan shared insights from a recent nuclear early careers campaign: “A 13% drop-off among female candidates between initial engagement and completed application highlighted exactly this kind of issue. The value was not in the number alone. It was in seeing the pattern early enough to review what was happening and make a targeted adjustment.” Build in room to change the assessment process Assessment processes also need room to flex. AI-assisted applications are now creating new graduate recruitment challenges and pressures across these safety-critical sectors. Organisations across nuclear, rail, and energy are having to think carefully about how they verify candidate understanding without adding unnecessary friction or delay. This might mean: Introducing an additional screening stage Changing the weighting of an assessment Adapting interview guidance for hiring managers Whatever the response, the key issue is whether the early careers programme can absorb that change without derailing the timeline. A resilient early careers strategy does not assume the original process will remain perfect from launch to offer. It creates the conditions to adjust when the evidence says something needs to change. Fixed supplier models can slow the decisions that matter Where a programme partner is treated as a supplier delivering against a fixed brief, responsiveness becomes harder. A small adjustment can quickly become a request that rolls into the need for reviews and approvals. By the time action is agreed upon, the campaign may already have moved on.That creates decision latency at exactly the wrong moment. For critical infrastructure organisations, the timing matters because internal teams are already carrying significant pressure. Dan noted: “Early careers hiring often sits alongside workforce planning, operational demands, stakeholder management and longer-term skills priorities. If the working model adds handovers or pushes decisions through extra approval loops, the programme becomes slower at the exact moment it needs to respond.” Shared ownership gives the programme room to move A shared ownership model means that both the organisation and the programme partner are working from the same data. Funnel performance is visible, and diversity movement is reviewed at each stage. When risks appear, they are discussed while there is still time to act. Decisions are made jointly, with clear ownership of what happens next. It also means the partner absorbs operational complexity rather than passing it back to the internal team. When attraction needs to shift, the response can be shaped quickly: Assessment spikes can be resourced before they become a bottleneck. Candidate communications can be updated before an issue becomes embedded. Stakeholders receive recommendations based on live evidence rather than end-of-campaign analysis. This is particularly important for organisations investing in an early careers strategy for the first time or scaling an early careers programme across multiple business areas, regions, or technical disciplines. The working relationship has to support the speed of the campaign. Otherwise, even good insight becomes too slow to matter. What to ask before your next early careers campaign Before the next campaign launches, the most useful questions are not only about process, platforms or attraction channels. They are about how the programme will respond when conditions change. What happens if application volume is lower than expected? Who decides when the campaign needs to change? How quickly can messaging, targeting or assessment be adjusted? Where is diversity being tracked beyond attraction? What happens if candidate behaviour shifts mid-campaign? How much pressure can the internal team absorb before delivery starts to suffer? For organisations in nuclear, energy, water utilities, and rail, these questions matter because early careers hiring feeds directly into long-term workforce capability. The strategy needs to look strong before launch, but it also needs to hold up once the campaign is live.
