The Colour-Coding System: The Simple Step That Can Make or Break Your CQC Inspection
When the Care Quality Commission (CQC) assesses infection control in your dental or GP practice, they’ll look for clear, consistent systems-not just a spotless waiting room.
One of the simplest ways to prove control, and one of the easiest to miss, is the NHS colour-coding system for cleaning.
It’s the small detail that can make or break your next inspection.
Why Colour-Coding Matters for CQC Compliance
The NHS introduced colour-coded cleaning tools to stop cross-contamination between high-risk and low-risk areas.
CQC inspectors expect to see this in action-and they’ll ask staff about it.
If a cleaner or receptionist can’t explain which colour mop is used where, it signals weak infection-control training.
A clear system shows:
- You’re following national guidance for infection prevention.
- Staff are trained, confident, and consistent.
- Cleaning is embedded into daily operations, not improvised.
The Four NHS Cleaning Colours-and What They Mean
| Colour | Use | Example Areas |
| Red | Washrooms, toilets, sanitary areas | WC cubicles, shower rooms |
| Blue | General, low-risk areas | Waiting rooms, offices, corridors |
| Green | Kitchens and food prep | Staff kitchens, break rooms |
| Yellow | Clinical and treatment areas | Dental surgeries, GP consulting rooms, isolation areas |
Inspector tip: Many practices fail this test because mops aren’t labelled, cloths are shared, or storage areas mix colours.
How to Keep Colour-Coding Consistent
- Label every item – buckets, handles, and cloth containers.
- Store by colour – separate shelving or wall hooks.
- Train and test staff – include a short refresher every quarter.
- Audit regularly – monthly checks ensure consistency.
- Document it – your logs should reference colour-coded zones.
This isn’t just compliance; it’s patient protection.
