Care home staff bank vs agency staff vs cross-provider carer sharing: what's cheapest?

In most cases, an in-house staff bank is the cheapest way to cover a shift, agency staff are the most expensive, and cross-provider carer sharing sits between the two — usually much closer to bank cost than agency cost, because you're paying a shared carer's rate plus a smaller platform or referral fee rather than a full agency margin. Which is actually cheapest for you depends on how often your bank can realistically fill the gap, because an empty staff bank slot doesn't save money — it just becomes an agency booking or a missed visit.

How the three options actually compare

Staff bank — your own pool of casual or flexible workers, already DBS-checked and trained on your systems. Cheapest per hour because there's no agency margin, but only as useful as the number of people in it and their availability. A small or tired bank often can't cover nights, weekends, or a sudden run of sickness.

Agency staff — external agencies supply carers at short notice, but you pay their hourly rate plus a margin that covers the agency's own overheads and profit. This is typically the most expensive route, and spot-booking (calling an agency last-minute for an unfilled shift) tends to cost more than a pre-booked agency shift. It's fast, but it's the option you reach for when nothing cheaper is available.

Cross-provider carer sharing — instead of paying an agency margin, you borrow a vetted carer from a partner care provider or a platform-verified freelancer, usually at a rate closer to what you'd pay your own bank staff. The saving comes from cutting out the agency middleman while still getting someone checked, trained, and available quickly.

Why carer sharing tends to land in the middle

The cost logic is straightforward: agency margins exist to fund the agency's recruitment, vetting, and management overhead for every placement. Carer sharing keeps the vetting (DBS, identity, training) portable — done once, reused many times — so each individual placement doesn't have to fund a whole new layer of overhead. That's the structural reason it can undercut agency rates while still giving you someone qualified, rather than an unvetted gap-filler.

The honest caveat: carer sharing only works if there's a genuine pool of trusted carers nearby who are free at the right time, and if both sides — your home and the carer's usual provider or platform — agree to the arrangement. It's not a replacement for your staff bank; it's what you turn to when the bank can't cover a shift, before you reach for agency spot rates.

What to actually check before assuming one is cheapest

• True hourly cost, not just headline rate — include any agency booking fees, mileage, or minimum-shift charges.
• Fill rate, not just cost — a cheap option that leaves shifts unfilled isn't cheap; it's a missed visit and a CQC risk.
• Vetting overlap — if a shared or agency carer is already DBS-checked and (where relevant) on the DBS Update Service, you shouldn't be paying to redo checks you can verify instead.
• Continuity — a slightly higher cost for a carer who already knows the resident (via a shared record and handover brief) can be cheaper overall than a cheaper but unfamiliar agency worker who takes longer and needs more supervision.

Where Nanum fits

Nanum is built around this middle option: care homes and agencies can request a vetted freelance or partner-agency carer to cover a gap, rather than defaulting to agency spot rates. Carer sharing on Nanum works on a request-and-accept basis — a human on each side agrees to the match, an AI engine only suggests and ranks the best-fit carer by proximity and continuity. A borrowed carer gets a consent-scoped handover brief so they can start safely and quickly, without needing full record access. The aim isn't to replace your staff bank, but to give you a cheaper, safer fallback than agency spot-booking when the bank runs dry.

FAQ

Is carer sharing always cheaper than agency staff? Usually, because it avoids a full agency margin, but not guaranteed — the actual saving depends on the shared carer's rate, any platform fee, and how far they need to travel. It's worth comparing the total cost per shift, not just the headline hourly rate.

Can a staff bank and carer sharing work together? Yes — most homes use the staff bank as the first port of call and turn to carer sharing (or agency) only for the gaps the bank can't fill. Carer sharing is designed to sit alongside a bank, not replace it.

Do shared or borrowed carers need re-checking for DBS and right-to-work? A borrowed carer should already hold a valid DBS check, ideally verifiable via the DBS Update Service, and appropriate right-to-work evidence — your home should still confirm this before the shift, as DBS and right-to-work responsibilities remain with the receiving provider. If in doubt, check current guidance with the DBS and Home Office directly.
