What is a productivity rate?
A productivity rate is the area one cleaner is expected to clean in an hour for a given task and standard. It is the basis on which cleaning contracts are costed and staffed.

</figure>Rates depend on the task, the equipment and the building. The same area cleaned to the same standard takes different times in an open office and in a partitioned one, and a rate applied without that adjustment produces a contract that cannot be delivered.
Because they set the labour hours, productivity rates decide everything downstream: the price, the staffing, and whether the specification is achievable. Most contracts that fail operationally failed at this point rather than on site.
Rates should be checked against reality after mobilisation. The gap between a modelled rate and an actual one is the most useful number a contractor can have, and almost nobody measures it.
In practice
A site priced off a rate card and a floor plan.
The hours work on paper. In the building, half the area is open-plan and the other half is twenty small rooms with doors, and the rate was built for the first kind of space.
Rates assume a shape of building as much as an area, and the gap between the assumption and the site is paid for by the cleaner going faster.
It shows up as audit scores drifting down from month two, which is read as a performance problem.
What goes wrong in practice
- Standard rates applied to an atypical building without a survey.
- Rates set to win a tender and never reconciled with what the work actually takes.
- Periodic work omitted from the model entirely, so it has no hours behind it.
- Never revisited after mobilisation, so the same error is repeated at renewal.
