15 Signs It's Time to Change Your Commercial Cleaning Company

Most businesses don't switch cleaning companies because of one major incident.

It's usually the small things.

At first, you notice a few fingerprints left on the glass in the reception area. Then the washroom bins aren't emptied one morning. A week later, staff mention that the kitchen doesn't seem as clean as it used to be.

Individually, these issues might seem minor.

But over time they add up, and before long you're spending more time checking the cleaners' work than focusing on your own business.

We've spoken to many businesses across London that stayed with an underperforming cleaning contractor far longer than they should have. Often it wasn't because they were happy with the service. It was because changing suppliers felt like another task they didn't have time for.

The reality is that a good commercial cleaning company should make your life easier—not create more work.

If any of the following signs sound familiar, it may be time to review your current cleaning arrangements.

1. Cleaning Standards Are Becoming Inconsistent

One week everything looks spotless.

The next week, desks are dusty, bins are still half full and the washrooms don't feel particularly clean.

Consistency is one of the biggest indicators of a professional cleaning company.

Anyone can provide a good clean occasionally. The real test is maintaining that standard every week, every month and every year.

2. You're Constantly Chasing Problems

How often do you find yourself sending emails that begin with:

"Just a quick reminder..."

If you're regularly pointing out missed tasks, your cleaning contractor is relying on you to manage their quality.

That's not how it should work.

Professional cleaning companies carry out their own inspections and identify issues before clients need to mention them.

3. Staff Are Beginning to Notice

Your employees spend more time in the building than anyone else.

They notice when soap dispensers are empty.

They notice dusty desks.

They notice unpleasant smells in the washrooms.

When staff start commenting on cleanliness, it's usually because standards have already been slipping for some time.

4. Cleaners Change Every Few Weeks

It's difficult to maintain consistency when a different cleaner turns up every week.

Regular cleaners become familiar with your building.

They know which meeting room is used most often.

They understand which areas need extra attention.

They learn your expectations.

High staff turnover often leads to inconsistent results.

5. Communication Has Become Difficult

Do your emails go unanswered?

Are phone calls returned days later?

Have promised improvements failed to materialise?

Communication is just as important as cleaning itself.

Problems occasionally arise in every business.

The difference lies in how quickly they're resolved.

6. Washrooms Never Feel Truly Clean

Washrooms are often the first place where declining standards become noticeable.

You might see:

• Watermarks around taps

• Soap residue on basins

• Empty dispensers

• Unpleasant odours

• Dust collecting behind sanitary bins

A professionally cleaned washroom should look, smell and feel hygienic throughout the working day.

7. Cleaning Takes Less Time Than It Should

Have you ever noticed the cleaners arriving and leaving surprisingly quickly?

Sometimes businesses assume faster means more efficient.

In reality, it often means important tasks are being missed.

We've visited offices where cleaners were expected to complete work designed for three hours in just ninety minutes.

No amount of efficiency can make up for insufficient time.

8. High-Touch Surfaces Are Being Missed

Since the pandemic, businesses have become much more aware of hygiene.

Door handles.

Light switches.

Handrails.

Kitchen appliances.

Lift buttons.

These areas should receive regular attention.

If they're consistently overlooked, it suggests the cleaning schedule isn't being followed properly.

9. The Cleaning Specification Isn't Being Followed

Every commercial cleaning contract should include a schedule of works.

If tasks listed in that specification are repeatedly missed, it's time to ask why.

The issue may not be the cleaner.

It could be unrealistic staffing levels or poor supervision.

10. There Are No Quality Inspections

One question we always encourage businesses to ask is:

"When did your supervisor last visit?"

If the answer is "I'm not sure," that's a concern.

Regular inspections help maintain standards and identify problems before they affect the client.

11. The Company Only Contacts You When It's Time to Invoice

A strong cleaning partnership involves ongoing communication.

You shouldn't only hear from your contractor when payment is due.

Professional companies check in regularly, ask for feedback and look for ways to improve the service.

12. Small Problems Keep Becoming Big Ones

Perhaps a vacuum cleaner has been broken for weeks.

Maybe damaged equipment hasn't been replaced.

Or repeated requests for additional cleaning have been ignored.

Attention to detail matters.

Businesses judge contractors not by whether problems occur, but by how they're handled.

13. Visitors Are Starting to Notice

Your workplace reflects your business.

Clients notice dusty reception desks.

Interview candidates notice dirty windows.

Patients notice untidy waiting rooms.

Parents notice the cleanliness of nurseries and schools.

First impressions are difficult to change.

14. You No Longer Feel Confident

This one is difficult to measure, but it's important.

When was the last time you walked into your building on Monday morning and simply expected everything to be clean?

If you're constantly checking corners, inspecting washrooms or wondering what you'll find, confidence has already been lost.

15. You're Reading Articles Like This One

Perhaps the biggest sign of all is that you're researching alternatives.

Businesses rarely search for a new commercial cleaning company because everything is going well.

If you're comparing providers, requesting quotations or reading advice on choosing a better contractor, it's probably because you already know something needs to change.

What Should You Look for Instead?

Changing cleaning companies doesn't need to be stressful.

The right contractor will make the transition straightforward.

Look for a company that offers:

• A detailed site survey

• Transparent quotations

• Directly employed and trained staff

• Regular quality inspections

• Clear communication

• Flexible cleaning schedules

• Experience in your type of business

Most importantly, choose a contractor that listens.

No two businesses are the same, and your cleaning schedule shouldn't be either.

Frequently Asked Questions

When should I change my commercial cleaning company?

If cleaning standards are inconsistent, communication is poor or you're spending time managing the contractor instead of your business, it may be time to review your current arrangements.

How can I switch cleaning companies?

Most professional cleaning companies will help manage the transition, including agreeing a start date, carrying out a site survey and ensuring there is no disruption to your business.

Will changing cleaning contractors cause disruption?

Not if it's properly planned. A reputable contractor will organise staffing, equipment and schedules before the first day of service.

Should I always choose the cheapest quotation?

No. Compare what is included, how many cleaning hours are provided and what level of supervision and quality assurance is offered.

Final Thoughts

Your cleaning contractor plays an important role in how your workplace looks, feels and functions every day.

If you're constantly following up on missed tasks, dealing with complaints or questioning whether the cleaning has been done properly, it's worth asking whether the relationship is still working.

A reliable commercial cleaning company should provide more than a clean building. They should provide peace of mind.
