Preparing for an infection-control or cleaning audit means having the evidence ready before the auditor arrives: a documented cleaning schedule, colour-coding, COSHH assessments and monitoring records, all mapped to the NHS 2025 cleaning standards and the IPC Code. This guide sets out what you are measured against and how to get audit-ready.
What a cleaning and IPC audit measures
Cleaning and infection-control audits check both the result (is it clean?) and the system (can you prove it stays clean?). In healthcare settings this is framed by the NHS National Standards of Healthcare Cleanliness 2025, which assign each functional area a risk category (FR1–FR6) with a target audit score and a public five-star rating, alongside the IPC Code and, for CQC-registered providers, Regulations 12 and 15. Knowing which standard applies to each area tells you the score you must hit.
Understand the FR scores and star ratings
Under NHS 2025, the target audit score rises with risk: FR1 areas (very high risk, such as theatres) target 98% and above and are audited weekly, down to FR6 (low risk, such as storage) at 75% and above audited annually. The star rating is public-facing — five stars means the target was met or exceeded, and any area at three stars or fewer must have an improvement plan with agreed timescales. Preparing means knowing your areas' categories and current scores before the auditor does.
Get the evidence ready
Auditors want a documentary trail. Have ready: the cleaning schedule (areas, tasks, frequencies, sign-off); BICSc colour-coding in use and evidenced; COSHH assessments for every product; method statements per area type; monitoring and previous audit results with any action plans; and training and vetting records for staff (Enhanced DBS where required). This is the same evidence base that a specialist provider supplies as standard — the backbone of clinical infection-control cleaning.
Walk the site and close the gaps
Do your own walk-through first, as an auditor would: check high-touch surfaces, clinical areas, washrooms and kitchens against the standard, and look for the details that lose marks — dust on high surfaces, grime at floor edges, mixed-colour equipment, missing consumables. Log what you find, fix it, and record the corrective action. A dry-run audit a week before the real one is the single most effective preparation.
Keep audit-readiness continuous
The practices that pass audits comfortably do not prepare for them — they are always ready, because the schedule, colour-coding, COSHH and monitoring run every day. That is the point of a properly specified contract: the evidence accumulates automatically.
