How Often Should a 20–100 Person Office Be Cleaned?

For most offices in this size range, the baseline is two to three professional cleans a week for smaller teams (20-49 staff) and daily cleaning once you're past 50, with high-touch areas like kitchens and washrooms cleaned every visit regardless of size. That's the starting point industry guidance converges on. The actual right answer depends on how your office is used, not just how many desks are in it.

Why headcount alone doesn't tell you enough

Two offices with 40 staff can need completely different schedules. A recruitment firm running back-to-back client meetings puts far more wear on reception, meeting rooms, and washrooms than a 40-person software team that rarely sees a visitor. A shared kitchen used by three departments needs more attention than one used by a single quiet team on flexible hours.

This is the bit a lot of quotes skip. A provider who prices off your staff count without asking how your office actually runs is guessing. We start with a walkthrough of the space and a few questions about how people use it: how many client visits a week, whether the kitchen gets heavy use, whether there's a rota of desk-sharing or hot-desking that changes the traffic pattern. The schedule comes out of that, not a template.

Baseline frequency by size

These are starting points, not fixed rules. An office at the low end of 50 with a quiet, internal-only culture can sometimes run on a heavier 3-4x weekly schedule instead of daily and still hold up fine. The way to know is to ask what's actually happening in the space, not to read it off a table.

What should happen at each frequency

• Every visit, regardless of schedule: Bins emptied, kitchen surfaces and sink cleaned, washrooms fully cleaned and restocked, high-touch surfaces (door handles, light switches, shared equipment) wiped down, floors vacuumed or swept in main traffic areas.
• Weekly, even on a lighter schedule: Desk surfaces dusted, glass and partition cleaning, skirting boards and edges, meeting room tables and chairs.
• Monthly: Deeper carpet vacuuming, window sills and frames, light fixtures, behind and under furniture where accessible.
• Quarterly or twice a year: Carpet shampooing, window cleaning (interior and exterior where accessible), upholstery cleaning, high-level dusting of vents and beams.

If your current cleaner only ever does the daily list and nothing on the monthly or quarterly tiers, that's usually where offices start looking tired even though they're being cleaned every day.

Signs your current frequency is wrong

• Desks or kitchen surfaces look untidy again within a few hours of a clean
• Washrooms run out of supplies between visits
• Staff have started doing their own spot-cleaning during the day
• Visible dust or grime shows up in the same spots week after week
• You've had more than one comment from a client or visitor about the state of reception

Any one of these usually means the frequency needs adjusting, not necessarily the provider. It's worth raising it before assuming you need to switch companies.

FAQ

Is daily cleaning necessary for a 30-person office? Not usually, unless there's regular client traffic or the kitchen and washrooms see heavy use. Most offices this size do well on 2-3 visits a week, with daily attention on the highest-use spots like the kitchen bin and washrooms handled separately if needed.

Should cleaning frequency change with hybrid working? Yes. If your office has fewer people in on Mondays and Fridays, a schedule built around actual attendance days uses the budget better than a flat weekly pattern that assumes full occupancy every day.

How do I know if I'm paying for more cleaning than I need? If the checklist above shows your office consistently looking clean well before the next scheduled visit, you may be able to drop a visit a week without a noticeable difference. A good provider will tell you this rather than let the contract run as-is.

Does a bigger office always need daily cleaning? Size matters less than density and traffic. A large, low-occupancy warehouse-style office can sometimes run on less than daily, while a smaller office with constant visitors might need it.
