Compliant Workforce Management at Scale

As your workforce grows, so does the complexity behind it. Our Manage solutions bring hiring, compliance and oversight under one accountable team, from large contingent programmes to outsourced permanent recruitment and the screening that clears every candidate.

What we do

When managing your workforce gets too complex to handle alone

Managing a workforce is about more than keeping roles filled. As organisations grow, change and deliver complex programmes, the challenge becomes creating visibility, consistency and control across people, processes, suppliers and risk. Rullion’s managed solutions bring that structure, helping you simplify delivery and strengthen workforce performance at scale.

Once a contingent workforce runs past a hundred people, managing it by hand stops being viable. A managed service programme pulls sourcing and compliance back under one accountable team and consolidates the invoicing that sprawls across suppliers, so an offshore wind farm or a rail framework can scale without chaos.

Permanent hiring is equally strained when volumes swing. Recruitment process outsourcing gives you a dedicated team to run the process end-to-end or to plug into your own, flexing as a power grid upgrade project ramps up and then settles back down.

None of it counts if candidates cannot start. Background screening verifies identity, right to work, and clearance before day one, cutting the wait from weeks to days so that mobilisation on a nuclear new build or a water framework is never held up by paperwork.

Three ways to manage your workforce

From large contingent programmes to outsourced permanent hiring and the checks that clear every candidate, our managed solutions bring order to how your workforce is run. Here is where each one fits.

Managed Service Programme (MSP)

Bring your contingent workforce under one accountable team. We run sourcing, compliance, timesheets, and payments across sites, so you can scale a large programme up or down without having to juggle multiple agencies.

Recruitment Process Outsourcing (RPO)

Hand over some or all of your permanent recruitment to a dedicated team that runs it from workforce planning through to onboarding, scaling with demand and plugging into your own function wherever you need it.

Background Screening

Clear candidates correctly the first time. Our vetting consultants and screening technology verify identity, right to work, and clearance before a start date, so hiring stays compliant and projects begin on schedule.

Why Rullion

Workforce management you can trust

In critical infrastructure, the cost of getting workforce management wrong is a missed start date or a compliance gap that stalls a programme. One accountable team, across hiring and clearance, is how we keep those risks off your plate and your projects advancing smoothly.

Four decades in critical infrastructure

For over forty years we have managed complex workforces for some of the largest organisations across nuclear, rail, energy, and utilities, delivering compliance and agility in industries where scrutiny never lets up.

Direct sourcing that controls cost

We cut reliance on third parties through direct sourcing, achieving over 90% direct fulfilment on most managed accounts, which keeps costs and supplier chaos down as the programme grows.

Technology that fits what you already run

Our technology approach supports the whole workforce journey, from VMS and supplier management to applicant tracking, screening and onboarding, integrating with your existing systems to improve visibility, consistency and control without unnecessary disruption.

Compliance built into every placement

From BPSS and DBS through to CTC, SC, and DV clearances, expert teams and screening workflows keep every placement legally and regulatory compliant in the safety-critical environments you operate in.

Relationships that last

A 90% client retention rate and contracts renewed over twenty years show how we work, and our industry-leading NPS of 93 reflects the same commitment to candidates. 

How Can We Help?

FAQs

Your questions, answered

A managed service programme manages your contingent workforce, coordinating suppliers, compliance and spend for contractors and temporary staff. Recruitment process outsourcing does the same for permanent hiring, running some or all of your recruitment function through a dedicated team. Plenty of organisations use both, with background screening sitting underneath either route to keep every hire compliant.

Yes, and it underpins both. Whether a candidate arrives through a managed contingent programme or an outsourced recruitment process, screening verifies their identity, right to work, and clearance before they start. On a nuclear or rail site, this means BPSS as a baseline, with CTC, SC, or DV layered on as the role demands

A contingent workforce is made up of non-permanent workers such as contractors, freelancers, temporary staff, and consultants, brought in on a flexible basis to meet short-term or project-specific demand. Managing a contingent workforce at scale is where a Managed Service Programme (MSP) adds value, bringing together scattered agency arrangements into a single, accountable programme.

It depends on the checks involved and how responsive candidates and referees are. Our advisor-led screening process has cut screening from around eight weeks to roughly eight days on average, helping to keep mobilisation on schedule. More detailed checks, such as international records or higher clearances, can take longer. 

No, that is a common misconception. RPO hiring suits organisations that hire over a thousand people a year, but it works just as well for smaller or fluctuating volumes and for businesses that are scaling up. The model flexes to your hiring rather than the other way round, which is why on-demand and hybrid versions exist alongside full outsourcing.

Yes. An MSP brings visibility and control to your contingent workforce; RPO extends the same rigour to permanent recruitment, and screening clears candidates on either route. When managed together, they allow you to manage everything through one partner instead of having to coordinate separate arrangements.
