How Modular RPO Can Enhance Your Permanent Hiring – Five Cost-Saving Benefits
HR and Talent leaders across the UK face an undeniable reality: traditional permanent hiring approaches are struggling to keep pace with what organisations now need – speed, quality, and a better candidate experience, delivered under intense cost pressure.
At the same time, the labour market remains challenging:
- 45% of employers anticipate problems filling roles in the near future.1
- 27% of UK employers have seen new starters fail to turn up on their first day.2
- 42% of candidates have left a recruitment process early because it took too long.3
Faced with these pressures, many businesses are shifting away from fixed, all-or-nothing outsourcing models and moving towards hybrid RPO – targeted support that strengthens the parts of their hiring process that need it most.
And momentum isn’t stalling, with a 15% increase in modular RPO deals over the last three years alone.4
Why Clients Are Choosing Modular RPO
The shift to modular RPO is being driven by what clients are telling us right now. Rather than knowing the solution they want, they come with a problem:
- They need a cost-effective way to expand capability.
- They can’t access quality candidates fast enough.
- They are struggling to fill unique, hard-to-fill roles.
- They have complex onboarding processes that slow everything down.
- They are seeing drop-off and disengagement mid-process.
- They are struggling to invest in adequate forward planning.
- They don’t want to increase HR headcount just to keep up.
This is where Adecco’s hybrid RPO comes into its own. Adecco’s approach is built on enhancement, not replacement. We work alongside our clients’ teams, preserving their culture and decision-making while adding specialist capability where it’s needed.
In a market where speed, experience and capability are proving decisive, this approach is becoming both a competitive advantage and a cost-saving one. This blog breaks down five practical benefits, with real client examples:
Modular RPOs Offer Better Speed to Value
Hiring delays aren’t always caused by a single issue; they are often the result of a combination of factors. When left unresolved, issues like slow shortlisting, limited sourcing reach, or stretched internal teams can quickly compound.
Business benefits you can expect:
60% of employers say hiring happens faster with an RPO.5 Adecco’s modular RPO is designed for rapid mobilisation, targeting the hiring stages creating the biggest delays and putting internal teams back on track:
- Quicker access to scarce talent and improved ROI.
- Faster progression through improved processes (including AI-enabled workflow support).
- Reduced drop-offs through faster scheduling and candidate comms.
- Rapid mobilisation for demand spikes (including on-demand recruiters deployed within 48 hours).
- Solutions implemented in weeks, not months.
Modular RPO in action:
A transport company needed to speed up select stages of the hiring journey to reduce drop-out in a highly competitive industry. By reinforcing stages where the client were struggling the most, we helped them quickly get hiring back on track. Across 12 months, we provided 220+ FTE staff, following which our contract was expanded to three additional sites.
Modular RPOs Improve Cost Efficiency
Cost pressure is now a permanent feature of workforce planning, and recruitment is often one of the first areas expected to do more with less. But costs go beyond agency spend – they include the added operational cost of slow processes, delays, and lost candidates.
Business benefits you can expect:
Adecco’s flexible approach to RPO lets organisations invest only in what’s needed, reducing overhead and maximising the value of recruitment spend:
- Reduced overheads by targeting only the stages creating waste.
- Faster and more consistent processes, with improved candidate retention.
- Flexibility to switch support on or off as needs change, removing fixed financial commitments.
- Daily or weekly rates that provide predictable costs without full RPO commitment.
Modular RPO in action:
A global manufacturer partnered with Adecco to hire over 100 specialists for a new facility. Embedded recruiters used targeted sourcing to reach scarce talent and build a strong pipeline. The project achieved 100% fulfilment, with 90% of hires via direct sourcing, delivering substantial cost efficiency and full launch readiness.
Modular RPOs Scale Up (or Down) More Easily
Most organisations don’t experience stable hiring; they have peaks, pauses, and urgent catch-up periods. Despite this, workforce planning often remains focused on the short term: CIPD found that 31% of organisations plan only up to six months ahead.2
Business benefits you can expect:
Modular RPO is designed to flex, adding capacity and specialist expertise without locking organisations into fixed resourcing:
- Surge capacity for hiring spikes, projects, new facilities, or sudden attrition.
- Specialist support for unique or hard-to-fill roles (without permanently expanding the function).
- Consistent governance and delivery even as volumes change.
- Ability to switch modules on or off as needs evolve.
Modular RPOs Enhance Control and Transparency
Organisations often resist outsourcing because they fear losing control. With a hybrid RPO, businesses choose exactly how much ownership to retain, from selective modules to full outsourcing.
Business benefits you can expect:
Adecco’s modular RPO enhances and integrates with existing capacity, allowing businesses to co-design the approach and maintain visibility:
- Clear governance and metrics across the modules selected.
- Better pipeline visibility and data-led insights.
- Improved performance reporting and stakeholder confidence.
- Stronger communication and transparency.
Modular RPOs are Built for Partnership and Performance
97% of employers say that having a trusted RPO partner allows them to focus on business-critical priorities.5
Business benefits you can expect:
Modular RPO is about more than boosting capacity – it’s a strategic partnership grounded in shared goals, clear metrics and continuous improvement. A modular RPO partnership focuses on:
- Better quality of hires and stronger candidate engagement.
- Continuous improvement against shared KPIs.
- The ability to modernise safely with technology and AI, without compromising governance and trust.
