Agency spend is eating your operating margin — here's the real number

Walk into a typical care group's finance review and you'll find one line item bigger than every other operational variance combined: agency. It's not new, and it's not surprising — but the size of it (in 2025-26 our reference set is averaging 17.4% of payroll, peaking at 31% during winter pressures) keeps surprising operators because nobody tracks it weekly.

Here's what we see across the operators using CareLoop. Three KPIs move the needle. None of them are about agency directly — they're upstream.

1 · Open-shift fill time

When a shift opens, how long does it take to fill from your own staff? Operators who track this hit a 14-minute median; operators who don't are at 4+ hours and reach for the agency phone before they've even tried.

2 · Cert expiry recovery rate

Of the staff whose certs expired in the last 90 days, how many were renewed within 14 days? Below 70% means you can't legally schedule them — and that's where agency creeps back in. It's a compliance KPI dressed up as a finance one.

3 · Bradford Factor watchlist size

The number of staff sitting at Bradford 200+. These are your future absences. Sit with the watchlist for 20 minutes a week with your HR business partner; agency cost trends down within a quarter.

What this looks like in practice

These three metrics are sparkline tiles on the CareLoop dashboard — they're meant to be glanced at over a coffee, not built into a board pack at month-end. The biggest unlock isn't insight; it's recency.

We weren't tracking the wrong things. We were tracking them on the wrong cadence.
