A workplace can look clean on the surface and still benefit from a proper deep clean.

Day-to-day cleaning is essential for keeping offices, schools, communal areas and commercial spaces presentable and hygienic. But over time, dirt, dust and grime can build up in the places that regular cleaning does not always reach.

So, how often should your workplace actually have a deep clean?

The answer depends on the type of building, how heavily it is used and what happens there day to day.

What is the difference between regular cleaning and a deep clean?

Regular cleaning focuses on the areas that need attention most often.

This could include:

A deep clean goes further.

It gives more time and attention to areas that may not be covered during everyday cleaning, including harder-to-reach or more heavily soiled spaces.

Depending on the site, this might include:

Think of regular cleaning as maintaining the building and deep cleaning as periodically resetting it.

So, how often should you book a deep clean?

For many workplaces, a full deep clean once or twice a year can be a good starting point.

However, some buildings will need more frequent periodic cleaning.

A busy workplace with hundreds of people coming through the doors each week will naturally experience more wear, dirt and dust than a smaller office with only a handful of staff.

Rather than working to one fixed rule, it is better to look at how your building is actually being used.

Busy offices and commercial buildings

For a typical office environment, a deeper clean every six to twelve months may be appropriate alongside a good regular cleaning schedule.

High-traffic areas may need additional attention more frequently.

Entrance areas, kitchens, toilets, stairwells and communal spaces tend to show wear much faster than quieter parts of a building.

It can therefore make sense to schedule periodic cleaning for individual areas throughout the year rather than waiting until the whole site needs attention.

Schools and education settings

Schools are a little different.

During term time, cleaners are usually working within tight windows around pupils, staff and daily school activity.

The school holidays provide an opportunity to carry out more intensive work while classrooms, corridors and communal spaces are quieter.

This could include machine cleaning floors, carpet cleaning, high-level cleaning, detailed washroom work and cleaning areas that are difficult to access during normal school days.

For many schools, the summer holidays are particularly important because there is a longer period available to complete larger periodic cleaning programmes before pupils return.

Warehouses and industrial environments

Warehouses, production facilities and industrial buildings can accumulate dust and dirt quickly.

How often they need deep cleaning will depend heavily on the work taking place inside the building.

Some sites may need scheduled periodic cleaning several times throughout the year, particularly where there is heavy footfall, machinery, loading areas or higher levels of airborne dust.

The important thing is to build the cleaning programme around the environment rather than applying a generic schedule.

There are a few signs your workplace may need a deep clean

Sometimes you do not need to wait for a date in the calendar.

Your building may already be telling you it needs some extra attention.

Look out for:

These can all be signs that everyday cleaning alone is no longer enough.

Deep cleaning can also protect your building

Periodic cleaning is not only about appearance.

Looking after carpets, flooring, fixtures and surfaces properly can help prevent dirt becoming deeply ingrained and may help extend the usable life of those materials.

Replacing commercial flooring or carpets can be expensive.

Maintaining them properly throughout the year makes far more sense than allowing them to deteriorate unnecessarily.

It also creates a much better environment for the people using the building every day.

The best approach is usually a planned cleaning programme

Rather than waiting until a workplace visibly needs a deep clean, it is much easier to plan periodic work in advance.

A professional cleaning provider can look at your building, understand how each area is used and recommend what should be completed daily, weekly, monthly or periodically.

That might mean one large annual deep clean.

For another site, it could mean carpet cleaning twice a year, machine floor cleaning every few months and a larger periodic clean during quieter periods.

There is no single schedule that works for every workplace.

The right cleaning programme should reflect the building, the people using it and the standard you want to maintain.
