One of the most common questions we get from employers is whether to bring in temporary staff or recruit permanently. There is no single right answer. It depends on how predictable your work is, how much training a role needs, and how quickly you need someone in place. Here is how we help clients think it through.
When temporary staff make sense
Temporary workers are the obvious choice when demand goes up and down. Warehouses ahead of peak, factories with a new contract, construction sites moving into a labour heavy phase, and cleaning contracts covering holidays all fit this pattern. Temporary staff are also useful when you are not yet sure a role will last, or you need cover for sickness, parental leave or a gap between permanent hires.
The main benefits are:
- Speed. A good agency can often supply people in days, sometimes hours, because candidates are already checked and ready.
- Flexibility. You can scale numbers up and down as the work changes, within the notice terms you agree.
- Less admin. When the agency employs the worker, it normally handles payroll, holiday pay and right to work checks.
When permanent hiring is the better choice
If a role is ongoing, needs real training or carries responsibility for people, customers or safety, permanent staff usually work out better. You get continuity, people who know your systems, and a team that builds up experience over time. Supervisors, skilled trades you rely on every week, and specialist roles in healthcare or engineering often fall into this group.
Permanent hiring takes longer and costs more upfront, through advertising, interview time and any recruitment fee. You also take on the full set of employment responsibilities. The payoff is lower turnover and less time spent training new faces.
Comparing the costs properly
On a simple hourly comparison, temporary staff often look more expensive, because the agency charge rate includes the worker's pay, employment costs and the agency margin. But that is not the full picture. When you employ someone permanently you pay for holiday, sick pay, pension contributions, training, management time and the cost of replacing them if they leave. You also pay for them during quiet periods.
A fair comparison looks at the total cost over a realistic period, and at how much of that time you actually need the person. For short or uncertain work, temporary staff are frequently the cheaper option once everything is counted.
Temp-to-perm: trying before you commit
Many employers use temporary placements as an extended trial. You see how someone performs, how reliable they are and how they fit with the team before offering a permanent job. Workers get the same chance to decide whether the role suits them.
If you go down this route, check the agency's terms of business before you start. Most agencies charge a transfer fee if you take on a temporary worker directly, or offer an alternative such as a longer hire period at the agency rate. These terms must be set out clearly in advance, so there should be no surprises.
The 12-week rule under the Agency Workers Regulations
The Agency Workers Regulations 2010 give agency workers certain rights. Some apply from day one, such as access to shared facilities like a canteen or car park, and being told about relevant job vacancies at the hirer.
After 12 weeks in the same role with the same hirer, an agency worker becomes entitled to the same basic working and employment conditions as if they had been recruited directly. That covers things like pay, working time, rest breaks, night work and annual leave. It does not cover everything: occupational sick pay, company pension schemes and redundancy pay, for example, are outside it.
A few points worth knowing:
- The 12 weeks do not have to be continuous. Some breaks pause the clock and some reset it, depending on the reason and length.
- Moving a worker into a substantively different role can start a new qualifying period.
- Structuring assignments to stop people ever reaching 12 weeks is specifically prohibited.
The hirer needs to give the agency accurate information about pay and conditions for comparable direct staff. Full details are on GOV.UK.
Often the answer is both
Most of our clients use a mix: a permanent core team supported by temporary staff when the work demands it. That gives you stability where it matters and flexibility where you need it.
If you are planning for a busy period or a new contract, our labour hire and permanent recruitment teams can help you work out the right balance. Get in touch and tell us what you are facing.
