How Cleaning Companies Can Improve Quality Control

Most cleaning companies think of quality control as "the supervisor does inspections". Inspections matter, but on their own they only detect problems. A quality control system prevents them, catches what slips through and makes sure the same problem doesn't come back.

Our cleaning inspection software page covers audits and scoring in detail. This guide covers the wider system around them.

The quality loop

1. Standard. What does "done well" look like?
2. Training. Does every cleaner know the standard and how to achieve it?
3. Self-check. Does the cleaner confirm the work as they go?
4. Audit. Does someone independent check results?
5. Fix. Are failures corrected quickly?
6. Learn. Do repeat problems lead to a change in process?

Weakness at any step shows up as complaints later.

1. Define the standard

"Clean" means different things to different people. For each area type, write a short standard:

• What's included: surfaces, touchpoints, floors, bins, consumables.
• What good looks like: "no visible dust on horizontal surfaces up to 2 m", "no streaks on glass", "dispensers at least half full".
• Photos of acceptable and unacceptable results. These are more useful than any paragraph.

Healthcare clients may require formal frameworks such as NHS England's National Standards of Healthcare Cleanliness. For other sectors, base standards on the contract specification and agree them with the client.

2. Train to the standard

• Site induction for every cleaner, including cover staff, covering priorities, layout and specification.
• Method training for techniques, colour-coding and equipment.
• Chemical safety, including COSHH information for the products used (HSE).
• Refreshers when audits show a pattern.

Record who has been trained in what, and when.

3. Build in self-checks

The cleaner is your first line of quality control. A short, area-based digital checklist completed during the shift prompts the cleaner to finish every task and creates a record. Keep it short enough to complete honestly.

4. Audit independently

Supervisor or manager audits:

• Use the same scoring scale for everyone, with defined scores.
• Score by area, not just overall.
• Follow a schedule based on risk, with more frequent audits for new contracts, high-risk sites and sites with recent problems.
• Include unannounced checks as well as planned ones.

5. Fix failures fast

Every below-standard result should create a corrective action with an owner and a deadline, often "before the next shift". Close it with evidence and re-check where needed. An action list that never closes is worse than none, because it shows the client you know about problems and haven't fixed them.

6. Learn from patterns

When the same failure repeats, ask why until you reach a cause you can fix:

Floors on level 2 score low → the cleaner runs out of time → the shift was cut from 3 to 2.5 hours when the client added a meeting room → the specification changed but the hours didn't.

The fix there is a scope and price conversation, not more pressure on the cleaner. Review patterns monthly by site, area and supervisor.

Handling complaints

Complaints are quality data. A good process:

1. Acknowledge the same day.
2. Investigate using attendance, checklist and audit records.
3. Fix the immediate issue and tell the client when.
4. Record the cause and the action.
5. Review complaint trends monthly.

Clients judge you less on whether problems happen than on how you respond. See proof of cleaning software for the evidence side.

Measure what matters

• Average audit score by site and area.
• Corrective actions open, and average time to close.
• Complaints per site per month.
• Checklist completion rate.
• Training completion.

Share results with cleaners too. Recognition for good scores improves quality as much as criticism of bad ones.
