When you commission a placement, you are not primarily commissioning a building. You are commissioning the staff team that will spend time with the young person day-to-day. Yet most commissioning conversations spend more time on property details than on workforce composition. This is a mistake — and this post is a practical guide to the workforce questions that actually matter.
The agency problem
High agency usage is a quality signal. Agency workers are not inherently worse than permanent staff, but they do not know the young people, the routines, the safeguarding context. A placement with 30% agency coverage is a placement where roughly one in three interactions is with someone who does not know the young person.
Ask the specific question: what is your agency usage rate, month by month, over the last six months? A provider operating under 10% is healthy. 10–20% is under pressure. Over 20% is a provider whose workforce is structurally unstable, and whose placements will reflect that instability.
Staff turnover
Turnover compounds. Every exiting staff member takes their relationships with them. For young people who have already experienced instability, new faces repeatedly are re-traumatising. A provider with 40% annual turnover is running a staff team that the young people in placement never really get to know.
Benchmark: under 20% annual turnover is good for the sector. Over 30% is a quality risk. Ask — and ask for trend data, not just a snapshot.
How gaps get filled
Every staff rota has gaps — sickness, leave, sudden resignation. The question is what the backfill looks like. A healthy provider has a mix: trained bank staff who know the placements, internal rotation for short cover, agency for genuine peaks. An unhealthy provider reaches for agency every time — which is how the agency rate creeps up.
Training standards
What should be mandatory before a support worker delivers an unsupervised shift?
- Enhanced DBS returned and confirmed.
- Safeguarding training completed — not just inducted.
- Right to work verified.
- Trauma-informed induction — meaningful content, not a morning's awareness session.
- First aid — current.
- Medication handling if relevant to the placement.
- Shadow shifts — paid, structured, with a competent senior worker.
- Probation review at three months.
Providers who let staff onto unsupervised shifts before any of these are in place are taking quality risks that will show up in incidents within weeks.
Supervision — frequency and depth
Supervision is where practice quality is maintained over time. Every six weeks is a good cadence. Every quarter is the bare minimum. Anything less is not supervision — it is administration.
Depth matters as much as frequency. Is supervision reflective (discussing specific situations, exploring practice, supporting emotional load) or administrative (ticking training boxes, checking compliance)? Both are necessary; the reflective part is what changes behaviour over time.
Vetting beyond DBS
"All staff DBS checked" is the minimum. Ask about:
- Reference chain — two references, taken up, recorded, before unsupervised work.
- Right-to-work verification — documented and kept current.
- Probation review process — at three months, with documented outcome.
- Rolling DBS — how often re-checked, and what triggers an earlier check.
- Values-based interview content — not just CV and experience.
The link between workforce investment and placement stability
The providers with the most stable placements are the ones investing most heavily in their workforce. The causation runs through relationships: low turnover means stable keyworker assignments, stable keyworker assignments mean relationships that hold, relationships that hold mean placements that survive challenging periods.
You can see this in the data when you have it. You can also see it in the soft signals: how staff talk about young people, how well they know the details, how confident they are about decisions they made yesterday.
TIFA Life's workforce model
Values-based recruitment rather than CV-first. Structured induction before any unsupervised shift. Supervision every six weeks. Agency usage under 10% across our footprint. Named keyworkers on every placement. Probation review at three months, documented.
