How often should an office be cleaned?

Most offices need some cleaning every working day and a deeper clean less often. The right frequency depends on how many people use the space, whether visitors come in, and how hard the kitchen and bathrooms are worked. Here's how to work it out for your office.

Open-plan office with meeting spaces

In short

  • Bathrooms and kitchens set the pace: if they're used every day, they need cleaning every day or close to it.
  • Small, quiet offices can often manage with one to three cleans a week.
  • Split the plan: busy areas often, desks and detail work less often.

The short answer

For most offices with a kitchen and shared bathrooms, three to five cleans a week keeps things under control. Very small offices, with a handful of staff and few visitors, can often manage with one to three.

The test is simple: if the bathrooms or kitchen look tired before the next clean is due, you need more visits, or a short visit just for those areas in between.

What decides the right frequency

  • Headcount. More people means more use of bathrooms, kitchens and floors.
  • Visitors. Clients and customers expect a clean reception and bathroom every time they visit.
  • How the kitchen is used. Lunch at desks means crumbs on desks and more bin runs.
  • Bathrooms. Count the people sharing each bathroom. Busy shared bathrooms need daily cleaning.
  • Floors. Carpet hides dirt longer than hard floors, but grit left in carpet wears it out.
  • Days in the office. Hybrid teams may only need cleaning after the busy days.
  • Industry. Clinics, childcare centres and food businesses need cleaning every day they operate.

Hybrid offices: plan cleaning around your busiest days in the office, not the calendar.

Mix frequencies instead of cleaning everything every time

A plan that does everything on every visit wastes money on some areas and still falls behind on others. Split it instead:

  • Every visit: bathrooms, kitchen, bins, high-touch points and busy floors.
  • Weekly: desks, internal glass, meeting rooms and a full vacuum.
  • Monthly: high dusting, inside the fridge, sills and skirting boards.
  • A few times a year: carpet steam cleaning, tile and grout, and pressure cleaning.

Our office cleaning checklist has the full list of tasks for each frequency.

Signs you need more, or less, cleaning

More cleaning

  • Bins overflowing before the next clean.
  • Complaints about the bathrooms, or soap and paper running out.
  • A sticky kitchen by the afternoon.
  • Dust you can see on desks and sills.

Less cleaning

  • The cleaner regularly finds little to do in some areas.
  • The office is half-empty most days.
  • Some rooms are hardly used, such as storerooms or spare offices.

When to add a deep clean

  • After renovations, fit-outs or moving furniture.
  • Before an inspection, audit or big client visit.
  • After illness has gone through the team.
  • When the carpet has grey walkways that vacuuming no longer lifts.

Questions about this guide

Is once a week enough for a small office?

It can be, if there are only a few people and hardly any visitors. Check the bathroom and kitchen mid-week: if they look tired, add a second visit.

Should the office be cleaned before or after work?

Either works. After hours keeps cleaners out of the way. Early morning means the office is at its freshest when staff arrive. Choose what suits your building access.

Can the cleaning frequency change later?

It should. A written plan makes it easy to add or drop visits as your team, hours or office change.
