When demand is project-based, temporary hires and contractors give you the flexibility to bring in specialist talent for the duration of the project.
Contract, Interim, and Temporary Recruitment
Rullion specialises in interim and contractor recruitment across critical infrastructure, sourcing talent at every level of seniority for rail, nuclear, energy and utilities organisations. Whether you need to respond to a sudden increase in workload, deliver a time-critical project, or cover absence, our temporary recruitment services ensure the right people are in place when you need them most.
Who needs temporary recruitment support?
Consider temporary staffing solutions if…
Skilled workers are needed for a specific project
An unexpected increase in workload is straining your team
A sudden surge in work can leave you short-staffed. Temporary recruitment fills the gap without adding long-term headcount.
Permanent headcount isn't the right option
Not every piece of work requires a permanent hire. A temporary or contract worker offers a more cost-effective, flexible solution that matches workforce demand.
Immediate access to specialist talent is critical
Temporary recruitment lets you bring in skilled professionals quickly, avoiding the delays of a permanent recruitment process.
You want to reduce the risk of a long-term hiring decision
Temporary workers can transition into permanent roles (temp-to-perm) if they prove to be the right fit, reducing the risk of long-term hiring decisions.

Our frequently asked questions
Temporary Recruitment FAQs
Contract recruitment is the process of engaging professionals on a fixed-term or project basis. It suits organisations that need specialist skills or short-term resource cover without the commitment of a permanent hire. It's often the default model for critical infrastructure organisations, such as those delivering major nuclear new build programmes, rail construction, and water infrastructure projects.
Both sit under the broader umbrella of interim and contingent workforce solutions, and the right choice depends on the nature of the work. Contract roles are typically project-based with defined deliverables and a fixed duration. Temporary roles more often cover shorter-term needs such as sickness, absence, or seasonal demand.
Yes. Compliance sits at the centre of what we do. We provide guidance and support across IR35, helping you manage umbrella company compliance with SafeRec, IR35 status determinations and understand your obligations, alongside AWR compliance, identity verification and contractor onboarding. We also coordinate sector-specific screening requirements, including DBS checks, security clearance, drugs and alcohol testing, and competency verification, so you can be assured the right people are joining your business.
Absolutely. Whether you need a single interim specialist or a full project team, we can scale our temporary recruitment services to match demand. For higher-volume or longer-term requirements, our contingent workforce management solutions and Statement of Work services may also be worth exploring.
It depends on the role and sector, but we move quickly. We maintain established networks of professionals across critical infrastructure. Many of whom we know well and have placed before, which means we can often reduce time-to-hire significantly compared with starting a search from scratch. Get in touch and we'll be straight with you about what's achievable for your specific requirement.
We take our duty of care to the contingent workforce seriously. That means providing award-winning contractor care through clear contracts, prompt and accurate payments, and ongoing communication throughout an assignment. Workers also have access to wellbeing support through Able Futures, and all placements are carried out in line with our Safe Rec commitment to health, safety, and sustainability.
Yes, we can! Engaging workers on specific deliverables or Statements of Work adds clarity, better cost management, and risk mitigation for all parties. If you know what needs doing, we can help you define the scope, source the right talent, and even manage delivery through to project completion. Find out more about our Statement of Work services.
We offer multiple worker engagement models designed to accommodate both client requirements and contractor preferences. Depending on the IR35 determination, workers can be engaged as a Limited Company or Personal Service Company, on a PAYE basis, or through one of our audited and approved umbrella company partners.
You don't need to have the answer before you call us. Share what needs doing, and we'll help you identify the most appropriate approach, whether that's contract, interim, permanent, or a blend.

John Walker - Rail Project Manager at Sizewell C
When Rullion were appointed as our Master Vendor they were faced with a really tough ask to work with our team to transition a large volume contractors, many of which were part of business critical projects, in a extremely short timescale ahead of the Christmas period. They were outstanding throughout this process ensuring clear communication with our team, recruiting managers and the contractors themselves. They supported us throughout the transition and went above and beyond to ensure it was a success and as a result we lost no contractors and the contract was able to launch successfully on 1st January.
