How to audit commercial cleaning quality against your specification

Start with the agreed task schedule

An audit cannot fairly score a supplier against tasks or frequencies that were never agreed. Use the room schedule and task list in the contract, including periodic work, to decide what is due on the day of inspection.

Define what a satisfactory result looks like for each task. Avoid a score that combines a missed washroom clean, a damaged floor and a broken dispenser as though they were the same failure.

• Area or room and the task being checked
• When the task was scheduled and when it was inspected
• Visible result and any relevant completion record
• Finding category: cleaning, maintenance, stock or excluded work
• Owner, agreed remedy and reinspection date

Choose inspection times that answer the question

Inspect shortly after the scheduled clean when checking delivery. A second inspection during occupation may answer a different question: whether the agreed frequency is sufficient for current use.

Record the inspection time and the building’s use since cleaning. Heavy traffic, a spill after service or a newly occupied floor may require a scope change rather than a complaint about the cleaner’s method.

Use a consistent scoring method

Use defined descriptions for pass, minor defect and missed or unacceptable task, or another scale both parties understand. Document why a score was given so the supervisor can reproduce the inspection.

Treat safety concerns separately from aesthetic preferences. Do not wait for a monthly average to address a hazardous condition; route urgent findings through the site’s safety process. Photographs can help, but obtain permission and avoid capturing people, confidential screens or personal information.

Agree corrective actions and verify them

A finding should identify the action required, the responsible person and the agreed completion time. Keep it specific: restocking an agreed dispenser is clearer than asking the team to improve the washroom.

After the correction, check the actual result and record closure. If the same defect returns, investigate access, task time, equipment, method, training or an unclear specification rather than repeatedly closing the same complaint.

Use the review to improve the contract

Discuss recurring findings with the supplier alongside occupancy changes, periodic-work schedules and outstanding maintenance. Keep a written record of any change to tasks, frequencies or price.

A routine visual audit does not establish clinical disinfection performance or certify regulatory compliance. Where the setting needs specialist testing or infection-prevention assurance, agree the method with the responsible competent team and keep those measures separate from general appearance scores.
