Ask any nursery manager how they fill a staffing gap and you’ll hear the same story. A call at 7am. A WhatsApp to the group. A call to the first agency, then a second, then a third. An hour later, maybe it’s sorted. Maybe it isn’t. This happens multiple times a week, across every site you run — and nobody has ever added up the bill.
The hours nobody is counting
The cost of manual staffing doesn’t show up on a single invoice. It’s hidden in the accumulated minutes your managers spend every week on tasks that should take seconds — or not happen at all.
Here is what a typical nursery manager loses each week just to keep the rota running:
Calling and messaging bank staff
Checking availability, chasing responses, and confirming shifts one by one via phone or WhatsApp.
3–4 hrs
Calling agencies when bank staff can’t cover
Contacting multiple agencies, waiting for responses, and comparing options under time pressure.
1–2 hrs
Timesheet management and approvals
Collecting paper timesheets, chasing sign-offs, and reconciling hours with invoices.
2 hrs
Processing agency invoices
Reconciling across multiple agencies, checking hours, and approving payments.
1–2 hrs
Compliance tracking
Monitoring DBS expiry dates, verifying qualification levels before every shift, chasing documents, and maintaining Ofsted-ready records across sites.
3–4 hrs
Estimated total per site, per week
10–14 hrs
Across a group of ten sites, that is up to 140 hours of management time every week — the equivalent of more than three full-time roles — spent on administration that generates no educational value whatsoever.
The agency cost hiding in your VAT
The margin agencies charge is visible on the invoice. What’s less visible is the VAT structure — and it compounds the problem significantly. With a traditional agency, VAT applies to the entire invoice. With Kalendit, you set the rate yourself and VAT applies only to the booking fee — not to the full shift cost.

“The question isn’t how much Kalendit costs. It’s what your current approach is already costing you — in money, in manager time, and in the stress of a 7am gap on a Monday morning.”
The invisible cost of hiring the wrong person
Beyond the weekly staffing grind, there is a bigger financial risk that nursery groups consistently underestimate: permanent recruitment. According to CIPD research, the cost of a bad hire is typically around 30% of annual salary. On a £24,000 salary, that is £7,200: notice periods, re-recruitment, lost productivity, and the disruption to your team and the children in their care.
DIY recruitment
~£370
Job board + manager time. Cheap upfront but carries full bad-hire risk of £7,200 if it goes wrong.
Recruitment agency
£3,600–£4,800
15–20% of £24,000 salary. Before you’ve seen the candidate work a single shift.
Kalendit pathway
£1,200–£2,400
Trial on supply first. Then a permanent introduction fee of 10% — on someone you already know works well in your setting.
