Why Two Similar Offices Can Need Very Different Cleaning Schedules

There are two offices of roughly the same size.

They have a similar number of desks, comparable floor space and perhaps even occupy neighbouring buildings.

It would be reasonable to assume that they require roughly the same amount of cleaning.

Quite often, they don’t.

The size of a workplace is certainly relevant when planning a commercial cleaning service, but square footage alone tells us surprisingly little about how much cleaning a building actually needs.

How the workplace is used can matter just as much as how large it is.

Occupancy Makes a Difference

Consider two offices designed for 100 people.

In one, hybrid working means perhaps half of those desks are occupied on a typical day.

In the other, most employees work from the office throughout the week.

The physical footprint may be almost identical, but the demands placed on the building are not.

More people generally means greater use of washrooms, kitchens, breakout areas, meeting rooms and circulation spaces. Bins fill more quickly. Floors experience greater traffic. Shared facilities require more attention.

Even occupancy itself is not necessarily consistent throughout the week.

A hybrid workplace might be relatively quiet on a Friday but particularly busy on Tuesday, Wednesday and Thursday.

A cleaning schedule designed around the number of desks would miss much of that picture.

Footfall Is Not the Same as Headcount

The number of employees based at a premises is useful information, but it does not tell us how many people actually move through it.

A relatively small office with a busy reception could receive customers, suppliers, interviewees and other visitors throughout the day.

Another, larger workplace might have almost no external visitors.

Entrances, reception areas, corridors and customer-facing facilities in the first building could therefore experience considerably greater traffic despite the organisation employing fewer people.

Where that traffic occurs matters too.

A principal walkway used by almost everyone in the building will require different attention from an area occupied by only a handful of employees.

Washrooms Can Tell a Different Story Again

Washrooms are another good example of why floor area can be misleading.

Their cleaning requirement is influenced far more by usage than by the overall size of the office.

The number of facilities available, employee numbers, visitors, working hours and patterns of use all contribute.

A building occupied continuously throughout a long working day may place very different demands on its washrooms from an office of comparable size that operates conventional hours with relatively low occupancy.

This is why washrooms need to be considered as facilities in their own right when planning a cleaning specification.

Kitchens and Breakout Areas Vary Enormously

The modern office kitchen can mean almost anything.

At one end of the scale is a small tea point containing a kettle and sink.

At the other is a substantial communal area with refrigerators, microwaves, food preparation surfaces, seating and facilities used by large numbers of employees throughout the day.

Both might appear simply as “kitchen” on a floor plan.

Their cleaning requirements are clearly not the same.

The same applies to breakout areas, staff restaurants and other shared spaces.

Understanding how these areas are actually used is considerably more useful than simply knowing that they exist.

Flooring Changes the Cleaning Requirement

Two identical floor plans can also contain completely different floor coverings.

Carpeted offices, hard floors, entrance matting and safety flooring each have their own routine maintenance requirements.

The proportion of each surface matters, as does where it is situated.

An entrance floor exposed to wet footwear and outside debris during the winter experiences different conditions from flooring within a quiet meeting room.

There may also be periodic requirements beyond the daily cleaning specification, such as professional carpet cleaning or specialist hard-floor maintenance.

The floor plan may be the same. The work required to maintain it may not be.

Customer-Facing Areas Often Carry Different Expectations

Not every part of a workplace necessarily requires exactly the same level or frequency of attention.

Reception areas, meeting suites and other customer-facing spaces can play an important role in how an organisation presents itself.

That does not mean other areas should be neglected.

It means the cleaning specification can recognise that different parts of a building have different functions and patterns of use.

A heavily used reception may need attention at a different frequency from an archive room that is rarely entered.

Treating both simply as floor area would make little sense.

Working Hours Matter

The operating pattern of the business also affects how a cleaning service can be delivered.

A conventional office occupied from Monday to Friday presents one set of circumstances.

A building operating extended hours, shifts or seven days a week presents another.

Cleaning may need to take place before employees arrive, after they leave or around people who remain on site.

Access and security arrangements can also affect when particular areas are available.

A suitable office cleaning schedule therefore needs to consider not only how much work is required but when it can practically be completed.

Some Workplaces Change During the Week

One of the most significant changes in office life has been the growth of hybrid working.

For many organisations, occupancy is no longer broadly consistent from Monday to Friday.

That raises an interesting question for commercial cleaning.

Should every task automatically be completed at exactly the same frequency regardless of how the building has been used?

Not necessarily.

A good cleaning specification should provide consistency where consistency is required, while recognising genuine differences in the demands placed on the workplace.

The objective is not simply to clean more or less.

It is to clean appropriately.

Why a Site Survey Matters

This is why a commercial cleaning quotation should ideally begin with understanding the premises.

A site survey allows the cleaning provider to look beyond the headline floor area and consider:

• occupancy and working patterns;
• levels of footfall;
• washroom facilities;
• kitchens and communal areas;
• flooring types;
• customer-facing spaces;
• access and security;
• existing cleaning arrangements; and
• the standards and priorities of the customer.

Only then does it become possible to build a cleaning specification around the workplace as it actually operates.

The Right Cleaning Schedule Is the One That Fits the Building

There is no particular virtue in cleaning something more frequently than necessary.

Equally, there is little value in specifying insufficient time or frequency for an area experiencing heavy use.

A well-designed commercial cleaning schedule sits somewhere between those two extremes.

It directs the available cleaning resource towards the areas and tasks that genuinely require it while maintaining the overall standard expected throughout the premises.

And because workplaces change, the schedule should not necessarily remain untouched forever.

Changes in occupancy, working patterns or building use can all provide a sensible reason to review whether the original specification still fits.

Going Beyond the Daily Clean

Not every cleaning requirement belongs within a daily cleaning specification. Commercial carpets and hard floors may periodically require more intensive treatment, washrooms can benefit from specialist deep cleaning, and buildings occasionally present requirements that need different equipment, techniques or expertise. ProAct’s separate Specialist Cleaning Division provides a range of standalone services for these requirements, whether alongside an existing ProAct cleaning contract or independently of one.

Frequently Asked Questions

How is an office cleaning schedule decided?

An office cleaning schedule should take account of more than the size of the premises. Occupancy, footfall, working hours, washroom and kitchen facilities, flooring, customer-facing areas and the way the building is used can all influence which tasks are required and how frequently they should be completed.

Does every part of an office need cleaning every day?

Not necessarily. Some facilities and high-use areas may require daily or more frequent attention, while other tasks can be scheduled less often. The appropriate frequency depends on how individual areas are used and the standard required within the workplace.

Can an office cleaning schedule be changed if our working patterns change?

Yes. Changes in occupancy, hybrid working, operating hours or the way different parts of a building are used can affect cleaning requirements. Periodically reviewing the cleaning specification helps ensure that the service continues to reflect the workplace as it currently operates.
