The Spring surge: Why May is a critical month for rail recruitment

April may mark the start of the new financial year, but it’s in May that the real pressure hits. Last month’s new budget releases are now translating into live project mobilisation, and projects are moving from planning to delivery, which means that demand for skilled rail labour is accelerating fast.

Why demand spikes at this time of year

In May, the sector truly shifts gear as several forces come together. Funding is live and project teams begin mobilising, triggering immediate labour requirements. There is an urgency at this point in the year as milestones are set out or amended, and teams come under pressure to hit Q2 targets. Contract awards that were finalised before April are also now moving forward often with tight onboarding windows.

The result of these converging forces is a sharp, if predictable, spike in labour demand and a market where competition for talent intensifies quickly.

Skills shortages emerging this year

This year’s Spring surge is already resulting in several pressure points across the sector. Heavy public and private investment in major infrastructure programmes means there is high demand for safety-critical roles such as Controllers of Site Safety (COSS), Engineering Supervisors and technical specialists such as Signalling Engineers. Unfortunately, skilled workers for these roles are being drawn from the same limited talent pool, heightening recruitment pressure.

An increase in national enhancement and maintenance work is further creating shortages of civil and track operatives with certain regions experiencing sharper labour constraints than others, where project timelines overlap. And, as most in the sector have seen for some time, compliance pressures are increasing demand for safety-critical training and creating workforce bottlenecks as companies struggle to keep pace with the certifications required.

These pressure points aren’t new, but they are certainly more pronounced at this point in the year.

The cost of reactive recruitment

By May, organisations that haven’t planned ahead often find themselves on the back foot, with significant consequences. When recruitment is driven by urgency without strategy, hiring managers can lose control of the process. Instead of selecting the best-fit candidates, they’re forced to take whoever's immediately available, which can lead to mismatches in skills, culture, or experience. Those mismatches often translate into higher turnover, additional training costs, and reduced efficiency on site.

The hidden cost of this disruption is that managers end up diverting time away from delivery to firefight recruitment gaps, coordinate last‑minute onboarding, or rework schedules around missing competencies. That lost time has a real financial impact.

When recruitment is rushed, the margin for error narrows. Medicals, competency checks, and safety-critical assessments all need to be completed at pace, which increases the likelihood of delays or non‑compliance issues that can halt mobilisation entirely. In a sector where timelines are tight and margins are narrow, reactive recruitment quickly becomes expensive. A ripple effect of inefficiencies, risks, and operational strain is created which can undermine performance for the lifespan of the project.

Why don’t more rail companies just recruit earlier?

The reality is that rail companies often can’t recruit before budgets are released because most roles are tied directly to specific projects and funded from those project allocations. Until the financial year’s budgets or contract awards are formally released, hiring managers don’t have the authority to commit spend or bring people on board. Doing this too early would mean incurring wage, training and compliance costs without any guaranteed work to place candidates into, which is not viable in a sector with tight margins and frequently shifting programmes.

In terms of compliance, rail workers need medicals, PTS and safety‑critical competencies that all have expiry dates. Hiring too early risks those qualifications running out before the project starts, requiring the company to pay for them again. Add to that the fact that scopes, possession plans and delivery timelines can change right up to the point of mobilisation, and early recruitment becomes a financial and operational risk rather than a solution.

While early recruitment isn’t always possible, there are still practical steps rail companies can take to get ahead of the pressures that build at this point in the year.

Strategic recruitment planning still matters

While there are restrictions that are preventing early recruitment in rail, strategic workforce planning can still make a measurable difference to project delivery. Engaging talent now, even if there’s no immediate work, helps stabilise summer and autumn work banks, ensuring teams are ready to be put in place before the next wave of activity intensifies. It also allows rail companies to build a rolling talent pipeline as new phases of work come online, reducing the need for last‑minute cold-call hiring later in the year.

Better forecasting is another major advantage. By aligning recruitment with upcoming milestones, hiring managers can avoid the peaks and troughs that often lead to inefficiencies. Compliance and onboarding processes also run more smoothly with more time to plan; even a few extra weeks can significantly reduce risk, administrative pressure and cost.

This is also where recruitment agencies with an engaged network of workers really come into their own. Specialist recruiters will know who is nearing the end of a contract, have regular conversations with those seeking work, and possess the connections within the industry that they can approach when necessary, alleviating a significant part of the burden from rail employers.

Indeed, our approach at MSS Infrastructure (MSSI) can add real value to the sector. We support our clients with talent pooling, rapid mobilisation support and strategic workforce planning, in order to stay ahead of demand and maintain the workforce stability needed for consistent delivery.

May is the month to take control
