Temporary drivers vs permanent drivers
Neither is better. They solve different problems and most operations need both. The mistake is using one where the other belongs.
The real distinction is certainty, not cost
The usual framing is that permanent drivers are cheaper per hour and agency drivers are more flexible. That is true as far as it goes, but it misses the thing that actually decides the answer: how certain you are about the volume.
A permanent head is the right answer to work you are confident will still be there in a year. An agency head is the right answer to work you are not confident about, or work that exists in a shape a permanent contract handles badly — a six-week peak, a covering shift, a contract that has not been renewed yet. Buying certainty you do not have is how operations end up carrying heads through a quiet quarter.
Where each one fits
Permanent is right when
The volume is stable and proven. The role needs deep site or customer knowledge. Continuity with a specific customer matters. You want to build a culture rather than fill a seat. The work is full-time and predictable.
Temporary is right when
You are covering absence. Volume is above plan but unproven. A contract has just started. You are in a peak. The shift is one nobody wants permanently. You need somebody tomorrow rather than in six weeks.
Temp-to-perm is right when
You intend to hire permanently but want to see the person work first. It is the honest middle and it is under-used, largely because operators assume a transfer fee makes it uneconomic. Usually it does not.
Both, deliberately
Most stable operations run a permanent core with a standing agency percentage. That is not a failure to recruit. It is how you absorb variance without carrying it all year.
What the cost comparison usually misses
- The charge rate is not the wage. It includes employer National Insurance, holiday accrual, pension, the supplier's compliance work and margin. Comparing a charge rate to a bare hourly wage is comparing two different things and it makes agency look more expensive than it is.
- A permanent head costs money when there is no work. That is the whole point of a permanent contract and it is a real cost that never appears in an hourly comparison.
- Recruitment has a cost and a lead time. Advertising, screening, interviewing, checking and the notice period the candidate has to serve.
- An unfilled shift costs more than either. The vehicle standing, the drops rolled and the customer told a time that did not hold.
- Agency workers acquire rights. After twelve weeks in the same role the Agency Workers Regulations give equal treatment on basic conditions. That is not a trap, but it does mean long-term agency use is not a permanent discount.
Two cases where the answer is clear
Using agency for a permanent need. If you have covered the same seat with agency drivers every week for a year, you do not have a cover problem. You have an unfilled permanent vacancy that you are funding at a temporary rate, with worse continuity than a permanent hire would give you. The AWR clock will have passed twelve weeks long ago and the cost argument has stopped working.
Using permanent for genuine variance. If you hire to your peak, you carry the peak all year. Operations that do this usually know they are doing it and feel unable to stop, because the alternative feels like losing control of the establishment. A standing agency percentage is a more honest way to hold the same variance.
Temporary vs permanent — questions
Are agency drivers more expensive than permanent drivers?
Per hour worked, usually yes, because the charge rate includes employer National Insurance, holiday accrual, pension and compliance work that a bare wage figure does not. Across a year with variable volume the comparison often reverses, because a permanent head costs money in the weeks when there is no work for them.
How long can I use an agency driver for?
There is no legal maximum. After twelve weeks in the same role with the same hirer, the Agency Workers Regulations give the worker equal treatment on basic working and employment conditions. Long-term use is lawful, it just stops being a discount.
Can I hire an agency driver permanently?
Yes. That is temp-to-perm. A transfer fee applies, or you can opt for an extended period of hire instead — that alternative exists in the Conduct Regulations.
Should I use agency drivers for a peak?
That is one of the clearest cases for temporary cover. A peak is variance you can see coming and do not want to carry for the rest of the year.
