How to build a business case for changing your MSP provider

BLOGBy Rullion on 30 September 2025

Switching Managed Service Programme (MSP) providers is a major decision. Your first-generation MSP often brings early wins: reducing admin, consolidating suppliers, and bringing much-needed structure to hiring. But as your organisation evolves, those solutions can fall short. Visibility isn’t where it needs to be, processes don’t adapt, and the programme stops keeping pace with future goals. Often, these challenges can be addressed through open conversations with your current provider. But when they can’t, it may be time to consider changing your MSP provider and moving to a second-generation MSP provider, your next partner.

 

5 signs it’s time to switch MSP providers

For leadership, the decision often comes down to proving the return on investment, reducing risk exposure, and ensuring the MSP evolves alongside strategic priorities. Knowing when to make that move isn’t always straightforward, but there are common warning signs that can strengthen your business case:

Limited visibility

If you can’t access accurate, real-time data on workforce spend, supplier performance, or compliance, you’re operating blind. This makes it harder to control costs, demonstrate ROI, or make strategic decisions.

Processes that don’t adapt

When workflows remain rigid and fail to keep pace with evolving business needs or regulatory changes, inefficiency creeps in. This often leads to bottlenecks, slower mobilisation, and higher risk exposure.

Misalignment with strategy

Your MSP provider should act as a partner, not just an administrator. If the programme feels transactional and disconnected from your long-term workforce goals, it weakens your ability to deliver against wider business priorities.

Supplier limitations

An MSP that relies on a narrow supplier network restricts access to talent. This not only slows down hiring for specialist roles but also prevents you from tapping into under-represented or overlooked talent pools.

Lack of innovation

If reporting hasn’t improved in years, technology feels outdated, or the provider isn’t pushing continuous improvement, your MSP may be holding you back instead of helping you move forward.

The next step is turning these challenges into a structured argument that leadership can’t ignore: your business case.

 

What to include in a business case for switching MSP providers

The issues you’ve identified become the evidence, and the improvements you’re aiming for become measurable objectives. By structuring your case around these points, you’ll give stakeholders the confidence that switching MSP providers is a strategic decision, not just a reaction to frustrations.

Executive summary

Think of this section as the “elevator pitch” for your case. If a senior leader only reads one page, it should answer: Why change now, and what will we gain? 

Example: Our current MSP model is not providing the visibility, flexibility, or supplier reach we require. By transitioning to a second-generation provider, we can reduce average cost per hire by 15%, cut mobilisation timelines by 20%, and ensure full compliance visibility across our workforce.

 

Current challenges

This is where you turn warning signs into hard evidence. Leadership will expect more than anecdotes, so use data to back up your points. The stronger your evidence, the harder it is to ignore. Think rising time-to-hire figures, compliance gaps, or supplier underperformance. 

Example:

  • Reporting dashboards are limited, preventing us from tracking supplier performance in real time.
  • Average time-to-hire has risen from 28 to 53 days over the past 12 months, delaying project starts.

 

Objectives 

Objectives show what success looks like after the switch. They should be specific, measurable, and tied directly to organisational priorities. Think of this as the “destination” your business case is leading towards.

Example:

  • Reduce time-to-hire for technical roles by 20%.
  • Achieve 100% compliance audit readiness.
  • Introduce real-time workforce reporting by Q2.

 

Options analysis

Show leadership that you’ve weighed alternatives fairly.

A strong business case doesn’t assume switching is the only option. It shows leadership that every alternative has been considered. Presenting a fair comparison between staying with your current provider and moving to a new one makes your recommendation more credible and balanced.

Example:

Option 1: stay with current provider

  • Pros: continuity.
  • Cons: persistent issues unresolved.

Option 2: switch to new provider

  • Pros: wider supplier network, improved tech, better compliance.
  • Cons: transition costs, short-term disruption (if not managed effectively). 

 

Cost-benefit analysis

Demonstrate how switching creates measurable financial and strategic gains. This could be savings on cost per hire, avoided compliance penalties, or improved project delivery that translates directly into revenue.

Example:

  • Based on current hiring volumes, a reduction of £1,500 per hire equates to £225,000 in annual savings.
  • Avoided compliance fines (based on previous breaches) estimated at £50,000 annually.

 

Implementation plan

Even the best business case will raise the question, “How will we manage the transition?” Your implementation plan reassures stakeholders by showing how risks will be controlled and disruption minimised. Break the plan into phases and set realistic timeframes.

Example:

  • Phase 1: shadow mode (Months 1–2).
  • Phase 2: 50% requisitions managed by new MSP (Months 2-3).
  • Phase 3: full handover (Months 4–6). 

 

KPIs and success measures

Defining KPIs upfront makes your business case measurable and accountable. This section shows how success will be tracked after implementation. Clear measures help leadership see the long-term value of change.

Example:

  • Reduce average time-to-hire from 48 to 38 days within 6 months.
  • Achieve 95% supplier compliance with the agreed SLA by Q3.
  • Deliver full visibility of workforce spend by year-end.

 

Demonstrating ROI: cost vs value

Boards rarely approve a switch without seeing hard numbers. To win them over, your business case must prove that the value of change outweighs the cost of disruption. A simple three-step ROI model makes this clear: the cost of staying put, the cost of switching, and the value gained. Each step should be backed up with data and, where possible, linked to strategic business goals.

1. Cost of staying put

  • (Average cost per hire × annual hires)
  • Compliance breaches, project delays, supplier mark-ups 

2. Cost of switching MSP providers

  • Transition fees, internal resource time, short-term disruption 

3. Value gained

  • Savings from lower mark-ups
  • Reduced compliance risk
  • Faster mobilisation and delivery
  • Stronger supplier performance 


Example:

Our NWG MSP partnership: In 2025, NWG required mobilisation of Information Services (IS), data, cybersecurity, and change management roles with a 4-week deadline (over Christmas) to support their digital transformation. 

  • 100% of contractors were transitioned on time, despite a condensed four-week window and minimal legacy data.
  • Effective contingent workforce management with zero disruption to services, preserving business continuity across mission-critical information systems projects during a peak period for infrastructure planning.
  • £15,000+ saved in the first month alone through improved fulfilment routes and transparent rate control.

This example illustrates how value can be realised quickly. And, when combined with the ROI framework above, it helps build a case that is both credible and compelling.

 

Managing risks during the transition

Even with a strong business case, leaders will ask, “What’s the risk?” Anticipating these concerns will make your case more persuasive. For more guidance, our MSP Implementation Question Checklist highlights the questions you should ask during mobilisation to ensure your programme is set up for success.

  • Operational disruption – delays in hiring or mobilisation. The mitigation for this would be a phased transition, a parallel run for 1–2 months before full handover.
  • Supplier resistance – Preferred suppliers may hesitate to engage. Early communication, clear SLAs, onboarding support
  • Knowledge transfer gaps - Knowledge transfer gaps. Structured handover between outgoing and incoming MSP
  • Compliance lapses – Risk of exposure during transition. Align compliance checks with new provider from Day 1

 

Securing stakeholder buy-in

Different stakeholders view value differently. Map their concerns to your business case:

  • Finance/Board: ROI, predictable spend. Show annual savings, break-even point, and long-term value
  • HR/Operations: Talent access, time-to-hire. Evidence of a wider supplier network and faster fills
  • Compliance: Audit readiness, risk management. Highlight improved governance and real-time visibility
  • Procurement: Supplier performance, cost control, contractual efficiency. Demonstrate stronger supplier management, better rates, and transparent reporting
  • Project Managers: Mobilisation speed. Show reduced delays and faster project delivery

 

The long-term benefits of a 2nd Gen MSP

Your business case should end by showing how a second-generation MSP provider sets the organisation up for future success:

  • Real-time data for strategic workforce planning
  • Stronger governance in highly regulated environments
  • Access to broader supplier networks, including overlooked and under-represented talent pools
  • Faster project mobilisation, reducing time to value
  • Continuous improvement, not stagnation
  • This shifts the decision from a short-term fix to a long-term strategic investment. 

A well-structured business case turns the idea of switching MSPs from a reactive decision into a justified, proactive strategy. It helps provide the confidence that your next MSP partnership will deliver greater value.

And when you reach the point of preparing for mobilisation, our MSP Implementation Checklist is a practical tool to help you ask the right questions and ensure your new programme is set up for long-term success.

Rullion joins Energy & Utility Skills to support workforce planning

Rullion joins Energy & Utility Skills to support workforce planning

The UK’s energy and utilities sectors are preparing for a level of infrastructure investment that will require more than 300,000 new workers over the next five years. That challenge is not just about attracting more people into the sector. It is also about how organisations understand the workforce they need, how they access it, and how workforce planning connects to delivery in practice. As investment accelerates, workforce pressure is building across multiple fronts at once. Skills shortages remain well documented, but the challenge extends beyond supply. It also includes visibility, coordination, and the ability to plan across increasingly complex delivery models. Across infrastructure programmes, delivery relies on a mix of permanent teams, contingent labour, specialist contractors, consultancies and supply chain partners, often operating across different stages of the same programme. Workforce planning needs to reflect that reality, rather than focusing solely on traditional headcount. Rullion has joined Energy & Utility Skills  as part of this wider industry focus, contributing a distinct perspective as the only workforce solutions provider in the membership, with insight into how workforce strategies can better reflect the realities of delivery. Why Rullion has joined Energy & Utility Skills Energy & Utility Skills plays a central role in supporting workforce development across the energy, water and waste sectors. Through industry collaboration, workforce research and skills strategy, it brings together employers, partners and policymakers to address long-term capability challenges across critical infrastructure. Rullion has joined as part of that wider effort, contributing practical insight from across the extended workforce. While much of the industry focus is on attracting new entrants and developing skills pipelines, a significant proportion of delivery continues to rely on contingent labour, specialist contractors and external delivery partners. Bringing greater visibility to that part of the workforce, and how it interacts with permanent teams, is an important part of building a more complete view of workforce capability. James Saoulli, CEO at Rullion shared: “We’re proud to join Energy & Utility Skills and to be part of a community focused on addressing one of the sector’s biggest challenges - building a skilled, resilient workforce for the future. As investment accelerates across the energy, water and waste sectors, we believe there is a real opportunity to take a more integrated approach to workforce planning, bringing together both permanent and extended workforce models. We look forward to working with Energy & Utility Skills and its members to support the delivery of the UK’s net zero ambitions.” Workforce planning needs a broader view Much of the workforce challenge sits in the gap between the workforce organisations plan for and the workforce they actually rely on to deliver projects. These programmes are delivered through a combination of permanent teams, contingent workers, specialist contractors and wider delivery partners. Not all of that workforce is equally visible in planning discussions, despite playing a critical role in delivery. This is already becoming more visible across the sector, as organisations respond to growing pressure around hiring, skills access and delivery timelines. While the industry has spent years focused on decarbonisation targets, energy security and affordability are now accelerating investment and infrastructure upgrades. We explored this further in our recent piece on UK utilities hiring challenges employers cannot ignore in 2026. A more complete view of workforce demand allows organisations to plan with greater accuracy, particularly where delivery models are layered, timelines are long, and competition for skills is increasing across the market. Bringing insight from delivery environments Rullion brings more than 45 years’ experience supporting organisations across energy and utilities, working alongside companies including EDF Energy, E.ON and Northumbrian Water. That perspective comes from the delivery environment itself. Across major infrastructure programmes, workforce challenges rarely sit neatly within one hiring channel. They tend to emerge across the interaction between permanent teams, contingent labour and external delivery partners. This is where greater workforce visibility becomes important. Understanding where capability sits, how it is being deployed, and how different workforce models support delivery gives organisations a stronger basis for workforce planning. It also helps widen the conversation around skills. Not just in terms of how many people are needed, but how workforce capability is built, accessed and coordinated over time. A more joined-up approach to workforce capability Energy & Utility Skills plays a central role in helping the sector respond to long-term skills and workforce pressures across energy, water and waste. This includes connecting skills strategy more closely to infrastructure delivery, labour market access and future resilience. Rullion’s contribution will focus on practical insight from delivery environments, particularly around the role of the extended workforce and how organisations can take a more integrated view of capability. As the sector works to meet investment, decarbonisation and resilience goals at the same time, collaboration across employers, partners and industry bodies will remain essential. The workforce challenge is already clear. The next step is building strategies that reflect how delivery happens in practice.

Why nuclear education isn’t translating into job-ready talent

Why nuclear education isn’t translating into job-ready talent

The UK government’s recent overhaul of the nuclear system has moved focus toward faster build timelines and lower costs, with regulatory changes designed to remove delays that have historically slowed projects down. In parallel, the Nuclear Skills Plan increasing investment in nuclear education, particularly at postgraduate level, with the aim of strengthening the long-term talent pipeline needed to support this acceleration. This points to an assumption that if more people are trained, the workforce challenge will ease. But conversations across the nuclear industry suggest something more complex. Talent exists and interest in nuclear careers is growing, but there is a disconnect between how talent is developed and how the industry actually operates. As well as narrowed perceptions of the nuclear industry causing potential candidates to rule themselves out long before they’ve ever replied. The nuclear skills gap starts at entry level The nuclear sector continues to face a well-documented skills shortage and ageing workforce, increasing pressure on how new talent is developed. While universities produce strong academic foundations, particularly in engineering and physics, graduates are entering nuclear careers with a gap in exposure to the environments they are expected to work in. Nuclear is highly regulated and dependent on site-specific or procedural knowledge. New entrants need time to their translate academic knowledge into real-world capability and operational readiness in these safety-critical environments. That gap reflects the nature of the industry itself. As Rani Franovich, VP of Regulatory Strategy at Deep Fission noted during our conversation, much of that understanding is built through hands-on experience alongside operators, technicians, and safety teams on site. Nuclear careers are wider than STEM alone Access to nuclear careers is narrower in perception than it is in reality. The way nuclear careers are positioned still leans heavily on nuclear engineering pathways or specialised scientific roles. Whereas Nuclear projects operate as large-scale infrastructure programmes. As Rani Franovich, noted, “It takes a village to operate a nuclear power plant.” That village includes: Construction and skilled trade workers Regulators and policy specialists Project delivery teams Safety and compliance professionals Commercial and support functions When careers are framed too narrowly, large sections of the workforce never see themselves in the industry at all. Many potential candidates are ruling themselves out long before they ever apply. Making the talent shortage just as much an awareness gap as it is a skills gap. Interest in nuclear industry jobs isn’t translating into applications For many, nuclear still feels like a closed field. Highly technical, highly specialised, and only accessible through very specific academic routes. If someone doesn’t see a direct match between their background and that perception, they tend to rule themselves out without exploring further. That decision is often made before roles are fully understood and transferable skills are even considered. As Miguel Trenkel-Lopez put it, this isn’t a pure skills shortage. It’s a communication and awareness gap between what the industry needs and how those opportunities are understood. People with relevant experience in construction, infrastructure, project delivery, or other regulated environments don’t always recognise that their skills apply. At the same time, employers continue to look for candidates who already understand nuclear, reinforcing the idea that prior industry experience is a requirement rather than something that can be developed. The result is a mismatch on both sides. Talent exists and workforce demand exists. But they are not connecting early enough in the process. Nuclear capability is built through experience Nuclear capability isn’t something people arrive with fully formed. As Rani noted earlier, it’s developed over time through doing the job and gaining exposure to the operating environments. Jenifer Avellaneda’s path into nuclear reflects that. Her degree was in sustainable development engineering, not nuclear engineering. Her early exposure came through policy work at the International Atomic Energy Agency, followed by a transition into a technical role in probabilistic risk assessment. As Jenifer puts it, “you don’t need to be a nuclear engineer to come and work within the industry… We’re a super team here. Everybody’s welcome.” She describes a process of continuous learning, supported by mentors and hands-on experience. That pattern holds across roles. Supervised operations with simulation-based exercises and emergency drills as well as exposure to real systems build the level of judgement required in nuclear environments. The main obstacle into building this capability is creating clearer, more accessible entry points that reflect how the industry actually develops talent. That includes early careers routes with structured training in operating environments and lateral entry from adjacent sectors through structured reskilling and deployment models. If hiring continues to focus primarily on those already within the sector, the nuclear industry risks overlooking talent that is already capable, just not yet positioned within it. Nuclear career pathways are non-linear by design Once people enter nuclear, movement across roles, organisations and even sectors is common. Careers don’t follow a fixed path. They evolve through exposure and experience as opportunities show up across the nuclear programmes. That flexibility is built into the industry itself. As Rod Baltzer, Chief Executive Officer at Deep Isolation highlights, many of the skills required in nuclear already exist in adjacent sectors. Areas like oil and gas, construction, infrastructure, defence and other regulated environments all develop capabilities that translate directly into nuclear settings, from drilling and site operations to project delivery and technical oversight. This cross-sector movement is how the industry builds capability at scale. What can feel like a fragmented or unclear entry point is how the workforce is developed. The challenge is that hiring often doesn’t reflect that. Roles are still scoped around prior nuclear experience, even when the capability needed could be developed on the job. A large portion of viable talent remains outside the sector. Oversimplifying energy systems is distorting the nuclear industry narrative The way energy is taught has a direct impact on how nuclear is perceived. In many cases, education reduces energy systems to a simple classification: renewable or non-renewable. That framework is easy to teach. It is also misleading. Miguel Trenkel-Lopez highlights how this binary is introduced early, shaping how young people think about energy before they understand the system as a whole. Nuclear energy in particular is frequently misrepresented when it is grouped too simply into “non-renewable” alongside fossil fuels in the same category. Without acknowledging, lifecycle emissions, fuel efficiency, waste management, and its role in decarbonisation. It is interconnected, shaped by geography, infrastructure, policy, and demand. Renewable doesn’t always mean sustainable The term “renewable energy” is often treated as automatically “sustainable”, but the two are not the same. Miguel points to examples where renewable energy can become unsustainable, depending on how it is delivered: “Renewable isn’t the same as sustainable biomass, for example, becomes unsustainable if forests aren’t replanted, and even solar can fall short if its materials or labour practices are harmful. True sustainability goes beyond labels; it’s about long-term environmental impact, resource use, and people and the wider supply chains.” When considering whether an energy source is sustainability depends on a broader set of factors including: Long-term environmental impact Resource extraction and supply chains Land use and ecosystem balance Labour practices and social responsibility This wider picture is rarely reflected in early education. The result is a generation entering the workforce with a simplified view of energy, and nuclear positioned incorrectly within it. Why careers in nuclear need reframing The assumption that more education will solve the workforce challenge is understandable. It’s just not enough on its own. Across the industry, there is no single point of failure. What shows up instead is a gap between how people are developed, how roles are described, how hiring decisions are made, and the experience people need to be job-ready from day one. Capability in nuclear builds over time. It comes from exposure to real systems, and learning alongside experienced teams on site. Yet many entry points are still positioned as if that experience needs to exist before someone even gets through the door. This all continues to present nuclear careers as to narrow who sees it as an option. People with relevant backgrounds in construction, commercial, supply chain, infrastructure, or other regulated environments often don’t recognise their place in the sector. The work isn’t out of reach. It just needs to be described in a way that connects to what they already do. Shifting that starts with how roles are framed and how entry routes are designed. More clarity around where someone fits. More openness to adjacent experience. Better visibility of the types of roles that exist across nuclear programmes. A closer reflection of how capability is actually built once people are inside the industry. The talent is already there. It just isn’t finding its way in. Hot off the Grid Rullion’s Hot off the Grid series brings these perspectives from in-depth discussions with professionals working across the nuclear industry. From regulation and operations to education and early careers, the same themes continue to surface. You can explore these in more detail through our YouTube series.

Why your experience could be a fit for nuclear new build jobs

Why your experience could be a fit for nuclear new build jobs

You might not think nuclear is a career for you. Most people don’t. The nuclear industry is often seen as a niche industry dominated by scientists and technical experts. However, nuclear projects rely on a much broader workforce, drawing on talent from construction, infrastructure, rail, energy, manufacturing and many other disciplines. Many of the people working in nuclear and nuclear new build jobs started their careers elsewhere, moving across with skills that transfer directly into large, safety-critical, complex programmes. If you’re considering your next move, this is a good piece to understand how nuclear projects work and where your experience could fit. Jump to: What are nuclear new build programmes? Types of nuclear new build jobs Where these roles sit across a project Moving into nuclear from other industries Early career routes into nuclear Why the nuclear workforce will keep growing Find your place in nuclear new build What are nuclear new build programmes? One of the biggest misconceptions about working in nuclear is that most roles require a nuclear background. In reality, nuclear new build programmes look much more like large-scale infrastructure projects, involving the design, construction, commissioning, and eventually live operations of a station. These programmes run over decades and require thousands of people across a wide range of disciplines While nuclear can sound highly technical, much of the work will be familiar to people with experience in infrastructure, construction, engineering or major project delivery. The difference is the environment the work sits within. Nuclear projects operate under rigorous regulatory and safety frameworks, where quality, assurance and compliance are built into every stage of delivery. Across the UK, this major nuclear new build programmes are already underway. Hinkley Point C is in active construction and has become one of the largest infrastructure projects in Europe. Sizewell C is moving into its next phase, preparing for major construction activity. Alongside this, programmes such as Small Modular Reactors, including the Rolls-Royce SMR, and the STEP fusion programme are progressing and will introduce additional projects and supply chains across the UK. Projects like these involve far more than housing a nuclear reactor. They include marine works, cooling systems, large reinforced concrete structures, turbine halls, substations, transport infrastructure, accommodation facilities, and complex digital control systems. This scale and complexity necessitate thousands of roles across engineering, project delivery, construction, digital systems, and operations. Much of that demand is met by people entering the sector for the first time. If you’re new to the sector, it helps to understand how these projects are structured and where different skills come into play. For an overview of the nuclear sector and its career pathways, read our guide to UK nuclear careers. Types of nuclear new build jobs So where do you actually fit into all of this? Nuclear new build programmes teams still look very similar to those on other large infrastructure projects, just operating within a different environment. It can help to break these projects down by the types of roles they actually require to understand where you might fit. Engineering roles Engineering sits at the core of new nuclear build projects. Civil engineers design and deliver major structures, mechanical engineers work on plant systems, electrical engineers manage power infrastructure and instrumentation, and nuclear site engineers and control experts manage complex operational systems. The difference is applying those skills within a more regulated environment. There is strong demand for engineers who are used to working in complex, safety-critical environments, particularly those coming from major infrastructure, energy, oil and gas, or defence projects. Project delivery and commercial roles Nuclear new build programmes operate at the scale of megaprojects. Project planners, programme managers, commercial managers, contract managers, and project controls professionals all play a key role in keeping delivery on track. People often transition into nuclear through these functions, bringing experience from other large-scale projects. Where managing timelines, budgets, and complex supply chains is already part of the day-to-day. Construction and site-based roles Construction is where workforce demand is most visible. Structural works, logistics, heavy lifting operations, quality assurance, and site management all contribute to delivering large-scale infrastructure on site. Many of these roles are filled by professionals with backgrounds in construction, civil engineering, or major infrastructure projects, bringing experience that transfers directly into the nuclear environment. Digital and systems roles Modern nuclear infrastructure projects rely heavily on digital systems. This includes simulation environments, control systems, cyber security, and digital monitoring tools used throughout both construction and operations. Digital and system roles are becoming increasingly important as projects integrate more advanced monitoring and operating systems. Supply chain and procurement Behind every nuclear new build programme is a large and complex nuclear supply chain. Procurement specialists, logistics professionals, manufacturing teams, and commercial specialists ensure services, materials, and components are delivered on time and to specification. For those with experience in supply chain or vendor management, this sector is a key area where skills transfer directly. Health, safety and compliance Nuclear projects also rely on a wide range of support roles, which are often less visible but equally critical to delivery. Health and safety, quality, environmental management, onboarding, screening, and workforce planning are all essential to keeping projects compliant and operating safely. Roles you might not expect Some roles on nuclear projects sit outside the areas people typically associate with the sector. On projects like Hinkley Point C, teams include marine specialists managing offshore logistics and environmental experts protecting habitats. It’s a much broader workforce than most people expect, with opportunities extending well beyond traditional engineering or construction roles. If your experience sits outside traditional nuclear roles, there may still be a clear place for it within the wider project. Where these roles sit across a nuclear project Nuclear new build projects develop over long periods of time, taking 15 to 20 years from early planning through to operation. As each phase progresses, the type of work changes, and so does the mix of roles required. Workforce demand on nuclear projects does not increase gradually; it builds in stages. Often accelerating quickly once construction activity expands. Early development teams may involve a few hundred specialists focused on planning, design, licensing, and regulatory work. As projects move into main construction, that number increases significantly. This pattern has already been seen on Hinkley Point C. As construction moved from early works into full delivery, workforce demand increased rapidly, with thousands of people required onsite to run civils, mechanical and electrical, construction, logistics, and project delivery in parallel. A similar pattern is now emerging at Sizewell C. The site workforce has already grown to more than 2,000 people per day as activity has progressed, with further increases expected as additional phases begin to overlap. During peak construction, projects of this scale can require around 10,000 thousands of workers on-site. This is a defining feature of a new nuclear build. Once a nuclear new build programme moves beyond construction, roles shift towards testing, commissioning and operational readiness, followed by long-term opportunities in maintenance, compliance and plant support once stations are running. This means there isn’t a single entry point. Opportunities open up at different stages depending on your experience and where nuclear projects are in their lifecycle. Moving into nuclear from other industries Because opportunities open up at different stages of a project, many people enter nuclear during periods of construction and delivery, bringing experience from other industries. The transition itself is often more straightforward than expected. In many cases, people move into similar roles to the ones they’ve already been doing, but within a different project environment. Common transition paths include: Oil and gas engineers moving into energy infrastructure projects Defence and aerospace engineers transferring safety and systems expertise Construction professionals moving from transport or infrastructure projects Digital specialists working on control systems and simulation platforms Location is also an important factor to consider. Nuclear new build sites such as Sizewell C and Hinkley Point C are based outside major cities, which can involve working on-site or relocating closer to the project. For many, this brings a different kind of experience. You’re closer to the delivery of major infrastructure, working alongside large multidisciplinary teams and seeing progress as it happens. For many, that is part of the appeal. You’re building experience in real time, working alongside specialists from different disciplines, and contributing to something you can physically see taking shape. It’s a different pace and a different kind of visibility on projects that will operate for decades. Early career routes into nuclear Nuclear new build is focused on building a future workforce just as much as it is about hiring experienced professionals. This means the sector is actively opening up to new talent. There is also a growing focus on improving workforce diversity and creating more inclusive entry routes into the industry. Projects such as Hinkley Point C have already trained thousands of apprentices; Sizewell C will support significant training, apprenticeship, and graduate opportunities as construction progresses. For those earlier in their careers, these routes offer the chance to gain experience within a live national programme from the outset. This often includes structured training and exposure to site environments and technologies, all alongside the opportunity to work with experienced teams across a wide variety of disciplines. Over time, that experience can open up different pathways across the different phases of a nuclear new build programme, so you’ll have opportunities to progress with the programme as it moves from construction through to commissioning and long-term operations. Why the nuclear workforce will keep growing The demand for nuclear skills is not being driven by a single project. It reflects a broader pipeline of work across the UK future energy systems as part of the wider energy transition. Where new nuclear stations are being developed alongside emerging technologies such as Small Modular Reactors and fusion programmes, like STEP. Projects like Hinkley Point C and Sizewell C sit within this wider programme. While each project runs over decades, they also overlap with one another, creating continuous demand across different phases. For many people, this points to a career path more stable than a short-term hiring cycle. Experience gained on one project can carry across to the next. That longer lifecycle supports ongoing roles in maintenance, compliance, upgrades, and plant support long after construction ends. Find your place in nuclear new build Nuclear new build isn’t limited to those who have built their careers in the sector. No matter if you already work in nuclear or are exploring how your experience could transfer, nuclear new build offers the opportunity to work on some of the UK’s most significant infrastructure projects. At Rullion, we support organisations and supply chain partners across the nuclear sector, helping connect people to opportunities across major projects like Hinkley Point C, Sizewell C, and the STEP fusion programme.
