As we move through the first quarter of 2026, the Contract and Interim Health, Safety, Environment and Sustainability market has started the year with strong levels of activity.
In contrast to some of the caution we saw across parts of 2025, the early months of this year have been characterised by a clearer willingness from organisations to engage interim support, particularly where there is a direct impact on delivery, compliance or risk.
While broader economic conditions in the UK remain mixed, with continued cost pressures and ongoing scrutiny on budgets, this has not translated into reduced demand. Instead, it has reinforced a more targeted and deliberate approach to resourcing.
Alongside this, many organisations are continuing to navigate wider global uncertainty, particularly the ongoing conflict in the Middle East and its potential impact on energy supply and global supply chains. While this has understandably contributed to a more cautious backdrop, the UK market has, to this point, remained relatively resilient. How long this resilience will hold remains uncertain, but it is clearly influencing a more considered and risk-aware approach to resourcing decisions.
Workload is driving demand
The most consistent theme we are seeing so far in 2026 is simple: Workload.
Across construction, manufacturing, infrastructure and corporate environments, many organisations are operating with lean teams while managing increasing regulatory, operational and project demands.
Common scenarios include:
Multiple live projects or programmes running simultaneously
Increased regulatory pressure (Building Safety Act, CDM, ISO)
Backlogs in audits, risk assessments or system improvements
Permanent hiring delays or challenging processes
In many of these cases, the challenge is not long-term structure, it is immediate capacity and capability. As a result, interim and contract support is being used to bridge that gap and keep delivery on track.
Speed and immediacy are critical
We have seen a noticeable increase in requirements where timing is critical.
Clients are often looking for:
Immediate availability
Sector-specific experience (e.g. infrastructure, waste, data centres)
Individuals who can operate with minimal onboarding
In these situations, the value of interim support is not just expertise, but speed. The ability to mobilise quickly and stabilise a situation is often the deciding factor. This has placed greater emphasis on networks, pre-qualified candidates and a clear understanding of the brief from the outset.
Interim support is enabling permanent hiring
Another clear trend is the use of interim professionals alongside, rather than instead of, permanent recruitment.
We are regularly seeing organisations:
Bring in interim support after a failed or delayed permanent process
Use contractors to maintain compliance during recruitment drives
Prepare functions ahead of a senior permanent hire
This approach allows organisations to avoid operational disruption, while still taking the time to secure the right long-term appointment. In many cases, it also improves the success of the permanent hire by ensuring systems, processes and reporting structures are already in place.
Projects over positions
As with 2025, we continue to see a shift towards outcome-led assignments. Interim professionals are increasingly engaged to deliver specific pieces of work, such as:
Management system design and implementation
Building Safety Act and CDM-related support
Safety culture and behavioural change programmes
Contractor management and multi-site standardisation
Compliance uplift and audit readiness
This reflects a more mature approach to interim resourcing, focused on solving defined problems rather than simply adding headcount.
Economic pressure is shaping smarter decisions
The wider UK economic backdrop is still influencing behaviour. With ongoing pressure on margins, cautious investment and continued scrutiny on headcount, many organisations are:
Delaying permanent hires
Re-scoping roles before committing
Looking for flexible, lower-risk solutions
Interim and contract support often fits well within this context, providing:
Immediate expertise without long-term commitment
Flexibility to scale resource up or down
Clear return on investment through defined deliverables
What this tells us about the market
The early part of 2026 points to a market that is active but considered. Demand is not being driven by growth alone, but by necessity - maintaining standards, managing risk and ensuring delivery in the face of constrained internal resources.
For organisations, the focus is increasingly on:
Solving specific problems
Maintaining operational continuity
Making informed, flexible resourcing decisions
For contractors, this continues to favour those who can demonstrate:
Immediate impact
Clear project delivery experience
Flexibility and adaptability across environments
Looking ahead to Q2 2026
If current trends continue, we expect:
Continued demand for interim support linked to project delivery and compliance
Further use of contractors to support permanent hiring processes
Ongoing demand for sector-specific expertise
A sustained mix of both full-time and fractional assignments
More broadly, the market appears to be settling into a pattern where interim and contract support is not a reactive measure, but a planned part of workforce strategy.
How contractors can stand out in this market
With demand remaining strong but more targeted, the contractors who are securing the best opportunities are those who can clearly demonstrate value from the outset. In our experience, the most in-demand interim professionals are those who:
Position themselves around outcomes, not availability : Clients are engaging contractors to solve specific problems, not just fill gaps. Being clear on what you deliver, whether that’s stabilising a function, delivering a project or improving systems, makes a significant difference.
Show relevant, sector-specific experience : Experience in similar environments (e.g. construction, infrastructure, manufacturing or high-risk operations) is often a key deciding factor, particularly where timeframes are tight.
Demonstrate the ability to add value quickly : Contractors who can evidence how they have made an impact within the first few weeks of an assignment tend to stand out, especially in fast-moving or high-pressure environments.
Remain flexible in how they engage : With a continued mix of full-time and fractional roles, those open to different working models are often better positioned to access a wider range of opportunities.
Ultimately, contractors who align themselves to the way clients are now thinking (focusing on delivery, clarity and impact), are best placed to succeed in the current market.
