Thin margins make small gains matter
Commercial cleaning runs on low margins across many sites. A few percentage points of labour efficiency or consumables waste is the difference between a profitable contract and a loss-making one.
The data exists - rostering, time and attendance, consumables issued, inspection scores, client complaints - and is rarely brought together.
Site-level profitability
Most contractors price sites from a specification and a standard rate. What each site actually consumes in hours, travel, consumables and supervision varies considerably from that.
- Actual hours against specified hours, including overruns
- Travel between sites for staff covering several
- Consumables issued per site against square footage
- Supervision and quality inspection time
- Cover and overtime rates for that site
- Rework triggered by complaints
Bringing this together usually reveals that a minority of sites consume a disproportionate share of margin. That informs repricing at renewal, which is where the value is realised.
Consumables forecasting
Consumables are ordered on experience and topped up reactively, which produces both stockpiles at some sites and shortages at others.
Usage is predictable from building occupancy, site type, area, day of week and season. A forecast per site supports consolidated ordering and less emergency purchasing at retail prices, which is a direct cost saving.
Occupancy data, where the client provides it, improves this substantially. An office at half occupancy uses very different volumes from the specification written before hybrid working.
Targeting quality inspections
Inspection capacity is limited and usually allocated on a rota. Predicting which sites are most likely to fall below standard allows the same inspection effort to find more problems.
| Signal | Why it predicts a problem |
|---|---|
| Recent staff change at site | New staff, unfamiliar specification |
| High cover rate | Different people each visit |
| Previous low scores | Persistent issues recur |
| Client complaint history | Expectations mismatch or real problem |
| Time since last inspection | Standards drift without oversight |
Used to direct supervisors rather than to discipline staff, this improves service and client retention - which in a contract renewal business is worth more than the inspection efficiency itself.
Scheduling and travel
Where staff cover multiple sites, travel is unpaid or paid time that produces no cleaning. Optimising allocation to reduce it improves both cost and staff retention, which is a significant issue in the sector.
This is an optimisation problem with prediction inputs - how long each site actually takes, which varies more than specifications suggest. Our note on predicting service time covers that half.
Most contractors know which clients pay well. Far fewer know which sites actually cost what they were priced at.
