Needs-based cleaning: pay for the cleaning you actually need

Open-plan office with empty and used workstations illustrating variable occupancy and needs-based cleaning

Demand-driven cleaning means you pay to clean an area when it has actually been used or is dirty, not because the schedule says every other Thursday. The frequency is controlled by occupancy and condition instead of a fixed calendar. In an office where many people work from home two or three days a week, half the open-plan area often remains untouched while the cleaner cleans it just as thoroughly as if everyone were there.

What is demand-driven cleaning?

Traditional cleaning is frequency-driven. The agreement states "daily vacuuming, weekly floor washing," and it is performed regardless of whether the room has been used. It is easy to set up and predictable to bill. The problem is that usage is rarely even. A meeting room can be empty for an entire week, while the reception area is trafficked every day.

Demand-driven cleaning turns this around. We clean where it is needed, when it is needed, and document that the result maintains an agreed-upon level. Two things must be in place for it to work: a way to know what has actually been used, and a way to prove that what is clean is clean enough. We solve the first with zones and data. The second with a quality standard.

This is not the same as cleaning less. It is about shifting effort to where it adds value, and away from areas that have not been in use.

How do you divide a building into zones?

Zoning is the foundation. You cannot demand-manage an entire building as a whole, but you can divide it into areas with different logic.

A practical division for an office building:

ZoneExamplesManagement
Hygiene-criticalToilets, canteen, changing rooms, kitchenFixed frequency, daily – here we take no chances
High-trafficReception, main entrances, stairs, elevatorFixed or frequent frequency
VariableMeeting rooms, quiet rooms, project roomsDemand-driven – clean after use
Low-trafficArchives, storage, rarely used wingsDemand-driven – inspection before cleaning

The point is that demand management does not apply to everything. A toilet must be cleaned every day regardless of what a sensor says, because the hygiene risk does not tolerate uncertainty. The gain lies in the variable and low-traffic zones, and that is where you should start.

How does the cleaner know what has been used?

There are several levels here, from simple to advanced. You don't need the most expensive to get started.

  1. Visual inspection. The cleaner assesses the room on site and skips what is obviously unused. Requires experienced people, but costs nothing in equipment.
  2. Usage markers. A small sign or magnet that the user turns when the room has been used, or chairs that are placed on the table after cleaning. Low-threshold and surprisingly effective.
  3. Sensor data. Motion sensors or presence sensors that many buildings already have for light and ventilation. These tell which rooms were actually in use and can feed a cleaning plan.
  4. Booking data. The meeting room system knows which rooms were reserved. That data already exists in the calendar.

Many businesses already have sensors for light and climate. The data basis is there; it's about connecting it to cleaning. We are happy to start simply, with inspection and usage markers, and add data where the building already has it.

One thing to be honest about: sensors say something about occupancy, not about spills. A room may have been empty and still need cleaning because someone spilled coffee the day before. Therefore, professional judgment is never gone; it just becomes better informed.

How do you know that what is clean is clean enough?

This is the objection many managers have immediately: if the frequency varies, how do I control that the quality does not drop? The answer is to measure the result instead of the effort.

NS-INSTA 800 is a Nordic standard for measuring and documenting cleaning quality. It assesses how clean an area actually is, on a scale from 0 to 5, regardless of how often or by what method it has been cleaned. This is precisely what demand-driven cleaning needs. When the agreement is linked to a quality level and not an hourly count, the result is what matters.

INSTA 800 is a standard that you as a buyer can use, not a certification a company "has." This is how you use it in a demand-driven agreement: agree on a quality level per room type, for example, level 4 in meeting rooms and level 3 in archives, and let the supplier document that the level is maintained. If you want to know more about how the standard works in practice, we have written more extensively about what INSTA 800 is for office cleaning.

Then you have a contract where the frequency can be flexible, but the quality requirement remains fixed. That is the security that makes demand management justifiable.

What is the gain compared to a fixed frequency?

The honest gain is that you stop paying for cleaning empty rooms. How much that amounts to depends entirely on your building.

An office with widespread home office arrangements, where occupancy fluctuates from 40 to 90 percent throughout the week, has great potential. Many areas remain untouched for much of the time. A building that is full and in heavy use every day has little to gain, because most of it actually needs cleaning anyway. Therefore, we do not promise a fixed percentage. Anyone who does so without having seen your building is guessing.

Beyond cost, there are other benefits that are easier to stand by:

  • Effort is shifted to where it counts. The time saved on empty rooms can be used for more thorough cleaning of heavily used zones.
  • Less chemicals and water. If you clean less often where it is not needed, you use less product overall. This is related to sustainable commercial cleaning, where reduced consumption is a goal in itself.
  • Better data about your own building. The zoning and occupancy give you insight into how the areas are actually used, which is useful far beyond cleaning.

Is this suitable for my office?

Demand-driven cleaning works best when three things are true: occupancy varies, you have zones that can tolerate flexible frequency, and you are willing to measure quality instead of counting hours. An office with a flexible home office arrangement meets all three.

It is poorly suited for buildings with fixed hygiene requirements in almost all rooms, such as healthcare institutions and production facilities with strict cleanliness requirements. There, a fixed frequency is still the right approach.

A natural combination is demand management together with daytime cleaning. When the cleaner is present during the day, they can see which rooms are in use and adapt their efforts then and there, without guessing based on a plan made the night before.

Safety and products

Demand management changes when we clean, not how safely it is done. Two rules remain constant regardless of the model. Never mix cleaning agents – use one product at a time according to the instructions on the label. And acid in the form of vinegar, citric acid, or descaler should never be used on natural stone, marble, granite, or slate, because it etches and causes dull spots. Always test a new agent in a hidden spot first.

How to get started

The safest way is to pilot, not to overhaul the entire building at once.

  1. Map occupancy. Is there sensor data, booking figures, or just a gut feeling about which areas are empty?
  2. Divide the building into zones according to the table above, and mark what must maintain a fixed frequency.
  3. Agree on an INSTA 800 level per room type, so the quality requirement is defined before the frequency is flexed.
  4. Run a pilot on one floor or one zone for two to three months. Measure quality and cost against the current agreement.
  5. Scale what works, and maintain a fixed frequency where the pilot shows that demand management is not profitable.

We at Vaskeladden are happy to work proactively with these types of models, but we always start by looking at your building before we promise anything. If you want to know what an office assignment costs initially, you can find the price range in the guide on office cleaning prices. A demand-driven setup builds on that, with zones and a pilot as the basis for the figures.

Frequently asked questions

What is needs-based cleaning?+

Needs-based cleaning means you clean an area when it has actually been used or is dirty, not because the calendar says it's Thursday. The frequency is controlled by occupancy and condition, and the quality is documented against an agreed-upon level, for example, NS-INSTA 800.

Does needs-based cleaning save money?+

It can cut unnecessary cleaning in little-used zones, but the benefit depends on the building's occupancy and how unevenly it is used. An office with three work-from-home days a week has greater potential than a building that is full every day. Request a pilot on one floor before calculating for the entire building.

How do you measure if the cleaning is good enough when the frequency varies?+

With NS-INSTA 800. The standard measures the result, i.e., how clean it actually is on a scale from 0 to 5, regardless of how often or how it has been cleaned. Agree on a quality level per room type, and the result is what matters, not the number of hours.

Is needs-based cleaning suitable for all buildings?+

No. Zones with fixed hygiene requirements, such as toilets, canteens, and changing rooms, should maintain a fixed frequency. Needs-based management is best suited for areas with variable occupancy, such as meeting rooms, quiet rooms, and parts of open-plan offices.
