An Honest Look at What’s Squeezing Temp Recruitment Margins

This is a guest blog by REC business partner, meet DWIGHT

If you run a temp or contractor recruitment business in the UK right now, you won’t need me to tell you that margins are under pressure.

But it is worth being precise about what is actually driving it, because the causes are stacking on top of each other in a way that makes this moment different from previous downturns.

NI Has Changed the Maths

April 2025 saw employer National Insurance Contributions rise from 13.8% to 15%, while the secondary threshold dropped from £9,100 to £5,000 per year. On their own, those changes would have been difficult but manageable. Together, they have created a double hit for temp-heavy agencies.

You are now paying NI on a greater portion of each worker’s earnings, and at a higher rate. For an agency managing a contractor on £30,000 a year, that adds around £865 to the annual cost of that placement. Scale that across a contract workforce of any size and the numbers become significant quickly.

That leaves agencies with an uncomfortable choice: absorb the cost or pass it on. If you absorb it, you’re compressing margins that were already tight. If you pass it on, you’re having difficult client conversations when clients are scrutinising every invoice.

Compliance Is Getting Heavier

At the same time, the Employment Rights Act is adding further compliance cost, with more still to come.

Since April 2026, employers have been required to keep detailed records of annual leave and holiday pay, while the new Fair Work Agency has been launched with powers to inspect, fine and bring enforcement action on behalf of workers.

For temp recruitment businesses, this adds more admin to a process that was already fiddly. Holiday pay for variable-hours workers has never been straightforward, and mistakes are likely to be more expensive.

Further provisions around guaranteed hours, predictable working patterns and agency worker rights are still working through consultation. Whichever way the detail lands, temp recruitment is becoming more heavily regulated, and compliance is going to cost more.

Clients Are Pushing Back

The timing could hardly be worse.

The broader hiring market has been cautious, and while early 2026 has shown some recovery, employers remain reluctant to commit. That has shifted negotiating power towards clients.

Hiring managers are better informed than they used to be. Internal talent teams have grown. Clients are increasingly willing to challenge fees, extend payment terms or explore alternatives.

If you are competing mainly on price, this is a difficult market to defend. Agencies with genuine specialism, strong candidate networks and a service clients cannot easily replace have more room to hold their margin.

Many agencies are also funding weekly or fortnightly payroll while waiting 60 to 90 days for client payment. When margins are already tight, the strain on cash flow can become very real, very quickly.

The Agencies Responding Well Are Changing the Model

The agencies managing this well do not have a silver bullet. They are making several changes at once.

The first is specialisation. Generalist recruitment is increasingly a race to the bottom on fees. Specialist agencies with genuine sector knowledge, deep candidate networks and demonstrable outcomes are in a stronger position to hold their rates.

The second is rethinking the back office. Compliance checks, timesheet processing, payroll, credit control, invoicing and reporting all require people. As margins compress, every additional head in the back office reduces what is left on a placement.

Forward-thinking agencies are automating these functions. Some are using managed digital workers to handle repetitive, rules-based processes at a fraction of the cost of a human FTE, without the NI liability on top.

meet DWIGHT, for example, works with staffing businesses to run back office functions such as payroll processing, credit control and compliance workflows through DWIGHT, a managed AI and RPA platform. He does not sit on the payroll. He does not accrue holiday. He does not require management overhead. When margins are tight, removing that extra employment cost can make a real difference.

If your back office costs are starting to affect margin, it may be time to look at where automation can take the pressure off without adding more headcount.

The Broader Point

These pressures are structural. The NI increase is permanent. Employment Rights Act compliance requirements are not going away. The cost of running a compliant, well-staffed back office continues to rise.

Agencies waiting for the market to recover before fixing their cost base may find that recovery alone does not solve the problem.

The businesses that come out of this period stronger will be the ones investing now in operational efficiency, genuine specialism and infrastructure that protects margin regardless of volume.

That may not be a comfortable message, but it is at least the honest one.
