Office cleaning frequency is one of the first things facility managers get wrong — either over-specifying (and burning budget) or under-specifying (and failing an HSE audit or landlord inspection). This guide gives you the real cadence that works for London offices in 2026, split by task, office size and sector.
Quick answer
For a typical London office of 20–100 staff: WCs, kitchens and reception daily, workstations daily (or 3× / week hybrid), internal glazing fortnightly, exterior windows monthly, and carpet + deep clean every 6 months.
Daily office cleaning tasks
Daily tasks protect health, image and lease compliance. In a London office they are effectively non-negotiable for any shared area:
- Empty all bins and replace liners (general, recycling, sanitary).
- Clean and disinfect all WCs, restock consumables, refill soap and hand towels.
- Wipe and sanitise kitchen worktops, sinks, fridges and microwaves.
- Clean reception desk, glazed doors and high-touch points (lift buttons, door handles, intercoms).
- Vacuum reception, kitchen, meeting rooms and any hard-floor spillage areas.
- Spot-mop hard floors in WCs, kitchens and lobbies.
- Restock consumables (blue roll, hand soap, toilet rolls, seat covers).
Weekly office cleaning tasks
- Full desk sanitisation including keyboards, mice, phones and monitors.
- Vacuum all carpeted areas — including under desks and around cable trays.
- Dust exposed surfaces, filing cabinets, shelves and picture frames.
- Clean internal glass partitions, meeting-room glazing and reception glass.
- Full mop of all hard floors with appropriate pH-neutral solution.
- Descale kitchen taps and WC taps; polish stainless steel.
- Clean skirting boards and wipe door frames at high-touch height.
Monthly & periodic tasks
| Task | Recommended frequency |
|---|---|
| Exterior windows (Reach & Wash) | Monthly (Central London) / Quarterly (suburbs) |
| Carpet deep clean (hot water extraction) | 6-monthly (annual minimum) |
| High-level dusting (light fittings, vents, tops of cabinets) | Monthly |
| Deep kitchen clean (behind fridge, oven, extractor) | Monthly |
| Upholstery / soft furnishings clean | Annually (6-monthly for reception sofas) |
| Gutter clearance & fascia clean | Twice yearly (spring + autumn) |
| Pigeon-proofing inspection | Annually |
Frequency by office type
Not every office needs the same cadence. Use the table below as a London-realistic baseline:
| Office profile | Recommended cleaning frequency |
|---|---|
| Small hybrid office (<20 staff, 2–3 days in-office) | 3× per week + monthly deep |
| Standard office (20–100 staff, 5-day) | Daily + fortnightly windows + 6-monthly deep |
| Corporate HQ (100+ staff, client-facing) | Daily + midday WC/kitchen check + monthly windows + quarterly carpet |
| Medical / dental practice | Daily clinical clean + weekly deep + monthly infection-control audit |
| Retail HQ / showroom | Daily + morning presentation clean + weekly window clean |
| Warehouse office / industrial | 3–5× per week + quarterly high-level clean |
Compliance & lease-driven minimums
Frequency isn't only a hygiene question. In London, several frameworks set an effective floor:
- Workplace (Health, Safety and Welfare) Regulations 1992 — WCs, washing facilities and rest rooms must be kept in a "clean state" at all times. In practice, HSE inspectors expect daily cleaning records.
- COSHH 2002 — dictates the chemicals used and the documentation kept per clean, not just the frequency.
- Landlord service-charge schedules — most London multi-let buildings specify a minimum frequency for common parts; check your lease before reducing spend.
- Insurer requirements — some employer's liability and business interruption policies require documented periodic deep cleans, particularly post-COVID.
Signs your office cleaning frequency is wrong
Increase frequency if you notice:
- WCs running out of consumables before the next scheduled visit.
- Visible dust on desks or monitors within 48 hours of a clean.
- Odour building in kitchen bins or fridges between cleans.
- Complaints from staff or visitors — a strong lagging indicator.
- Insurance or landlord audit findings citing hygiene shortfalls.
