The right cleaning frequency is risk-based, not one-size-fits-all. For offices and commercial premises it depends on footfall, use and hygiene risk, so a schedule is built area by area. In healthcare, frequency is formally graded under the NHS functional-risk categories FR1 to FR6, each with a set audit frequency and target score.
What decides how often premises should be cleaned?
There is no single legal frequency for commercial premises. The right interval is driven by how heavily an area is used, its hygiene risk, and its visibility. High-touch and high-footfall areas — washrooms, kitchens, entrances, desks — need more frequent attention than low-traffic storage. A good cleaning specification sets a frequency per area rather than a blanket rule.
Why frequency matters for safety, not just appearance
Cleaning frequency is a safety control as well as a presentation issue. Slips and trips on the same level account for around 30% of non-fatal injuries to employees reported under RIDDOR — the largest single category — and wet or contaminated floors are a leading cause. Getting the frequency and timing of floor cleaning right (and managing the wet period) directly reduces that risk.
How healthcare frequency is graded: the NHS FR categories
Healthcare cleaning is more formal. Under the NHS National Standards of Healthcare Cleanliness, every functional area is assigned a Functional Risk (FR) category from FR1 to FR6. The FR category sets the cleaning and audit frequency and the target audit score — the higher the risk, the more frequent the audit and the higher the required score.
Daily, periodic or deep clean — matching the method to the interval
Frequency planning usually layers three tiers: daily/regular cleaning of high-use areas; periodic tasks (for example, deep cleaning of carpets, hard floors or high-level surfaces) on a longer cycle; and one-off deep or reactive cleans. The best split depends on the building — which is exactly what a free site survey establishes before a fixed monthly price is set.
