Slow recruitment is causing delays. RPO providers help you fill roles faster and keep projects on track.
Recruitment Process Outsourcing (RPO)
RPO, or Recruitment Process Outsourcing, allows businesses to hand over some (or all) of their recruitment processes to a third-party RPO provider. It’s like having a dedicated team of workforce specialists who handle everything – from identifying your talent needs to sourcing, screening, and onboarding the best candidates.
A common view is that RPO services are only for large companies hiring over 1,000 employees a year, but that’s not the case. RPO is flexible and works just as well for businesses with smaller hiring volumes as for those scaling up.
Who is RPO for?
Your business could benefit from an RPO provider if…
Hiring takes too long
Recruitment costs are unclear and rising
You’re spending too much on hiring but are not sure why. RPO identifies inefficiencies and optimises your process to save money.
Specialist knowledge is lacking
Your team struggles to hire niche talent. An RPO model connects you with expert recruiters and industry-specific talent.
In-house team relies on a PSL
Even with an internal team, you rely on a preferred supplier list to fill 30 - 40% of roles. RPO optimises and strengthens your hiring processes.
Brand reputation is suffering
Bad candidate experiences are hurting your brand. RPO hiring improves the candidate journey, making your hiring more appealing.
Compliance and managing talent are getting harder
As your company grows, managing recruitment, compliance, and onboarding across various industries and regions becomes more complex. Recruitment process outsourcing is designed to handle it all.
Lack of long-term workforce planning
An RPO provider helps you plan for the future by supporting every stage of the workforce lifecycle, from recruitment and training to Statement of Work (SOW) management.

Recruitment Process Outsourcing FAQs
Our FAQs cover the most common questions about what RPO is and how it can help your business.
Recruitment Process Outsourcing (RPO) is when a company transfers some (or all) of its recruitment process to a third-party RPO provider. It’s a dedicated recruitment team that handles everything from identifying your talent gaps to sourcing, screening, and onboarding.
-
Cost efficiency: Reduces time and cost pressures on your internal recruiters and recruitment advertising expenses.
-
Scalability: Easily ramp hiring up or down based on demand.
-
Access to expertise: Gain specialist recruiters and advanced recruitment technology.
-
Improved quality of hire: RPO providers use specialist knowledge and efficient AI data-driven methods and talent analytics to find better matches.
-
Faster hiring: Streamlined processes and large talent networks speed up time-to-hire.
-
Enhanced employer branding: RPO partners often help enhance your brand image to attract quality candidates.
There are typically three main types of RPO hiring solutions:
End-to-End RPO: The RPO provider manages the entire recruitment lifecycle, from job profiling to onboarding.
On-Demand RPO: Used for specific projects or short-term hiring spikes, like seasonal hiring or new product launches.
Hybrid RPO: A flexible partnership that integrates with your internal team to share the recruitment workload, taking ownership of selected areas like sourcing, screening, or candidate engagement.
RPO differs from traditional hiring in that it involves a long-term partnership rather than a one-time service. An RPO provider collaborates with your team to manage all or part of your hiring process, with a focus on improving quality, speed, and cost efficiency. Traditional recruiting, on the other hand, is typically short-term and geared towards filling specific roles quickly, often for a fee per hire.
RPO is a good fit if your business hires regularly (regardless of company size) and needs help managing recruitment costs or wants to improve hiring quality. It’s especially useful if your HR team is overwhelmed or if you experience frequent unpredictable hiring patterns.

It's been a pleasure to have Lucy working on my recruitment, she has been very open with everything throughout the process, has always replied to my numerous emails and is always professional - very rare now within the recruitment business!
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.
