How Much Does Commercial Cleaning Cost in London? (2026 Price Guide)

One of the first questions businesses ask when looking for a cleaning contractor is, "How much is this going to cost?"

It's a sensible question, but the answer isn't always straightforward.

Unlike many services, commercial cleaning isn't sold as a one-size-fits-all package. Every workplace is different, and the cost depends on several factors, including the size of your premises, how often cleaning is required, the type of business you operate and the level of service you expect.

If you've received several quotations that vary significantly, you're not alone. It's common for businesses in London to receive prices that differ by hundreds of pounds each month.

So, why is that? And more importantly, how do you know whether you're getting good value?

This guide explains what influences commercial cleaning costs in London and what you should look for when comparing quotations.

Why Commercial Cleaning Prices Vary

If two companies are cleaning the same building, you'd expect their prices to be fairly similar. In reality, that isn't always the case.

One company may provide directly employed staff, regular quality inspections, professional equipment and comprehensive insurance. Another may rely on temporary agency workers, spend fewer hours on site and carry out little or no supervision.

On paper, both quotations may describe "office cleaning," but the service behind the price can be very different.

The cheapest quotation isn't necessarily the best value if standards begin to slip after a few weeks.

What Affects the Cost?

1. The Size of Your Premises

Larger buildings naturally take longer to clean.

However, it's not just the square footage that matters. The layout of the building also affects cleaning times.

An open-plan office is usually quicker to clean than a building with dozens of small rooms, meeting areas and multiple kitchens.

2. Cleaning Frequency

How often your premises are cleaned has a significant impact on the monthly cost.

Typical schedules include:

• Daily cleaning

• Five days per week

• Three days per week

• Weekly cleaning

• Fortnightly deep cleaning

Businesses with higher footfall generally require more frequent cleaning to maintain professional standards.

For example, a busy office with fifty employees will usually need daily cleaning, whereas a small consultancy with six staff members may only require two or three visits each week.

3. The Type of Business

Different industries have different cleaning requirements.

A medical practice or dental surgery requires strict infection control procedures and enhanced disinfection.

Schools and nurseries require additional attention to touchpoints and washrooms.

Retail premises may require cleaning before opening hours.

Each environment demands different skills, equipment and cleaning products, all of which influence pricing.

4. Cleaning Hours

Commercial cleaning is usually priced according to the number of labour hours required to complete the work to a professional standard.

If your premises require twenty hours of cleaning each week, the monthly cost will naturally differ from premises requiring forty hours.

A reputable company should explain how they have calculated the recommended cleaning hours.

5. Additional Services

Many businesses choose to include specialist services within their cleaning contract.

These may include:

• Carpet cleaning

• Internal window cleaning

• Hard floor scrubbing and polishing

• Washroom hygiene services

• Deep cleaning

• High-level dusting

• Consumable replenishment

Some companies include these within the contract, while others provide them as additional services.

Always clarify what is included before comparing quotations.

What Should Be Included in the Price?

A professional commercial cleaning quotation should normally include:

• Cleaning operatives

• Supervision

• Quality inspections

• Cleaning equipment

• Cleaning chemicals

• Insurance

• Staff management

• Holiday and sickness cover

If these aren't included, ask why.

Unexpected additional charges can quickly make a cheaper quotation more expensive than it first appears.

Should You Choose the Cheapest Quote?

It's understandable to want to keep operating costs under control.

However, cleaning is one of those services where buying purely on price can lead to disappointment.

Low-cost contracts often mean:

• Less time spent cleaning

• Higher staff turnover

• Inexperienced cleaners

• Limited supervision

• Poor communication

• Inconsistent standards

A slightly higher investment often results in a cleaner workplace, happier employees and fewer service issues.

How to Compare Cleaning Quotations

Rather than comparing the total monthly figure, compare what's actually included.

Ask yourself:

• How many hours will the cleaners be on site?

• Are cleaning materials included?

• Is supervision provided?

• Are quality inspections carried out?

• Are staff directly employed?

• Is holiday cover included?

• What happens if the regular cleaner is absent?

Once you have the answers, you'll have a much clearer picture of which quotation offers the best value.

Don't Forget the Hidden Cost of Poor Cleaning

Choosing the wrong cleaning contractor doesn't just affect cleanliness.

It can also lead to:

• Staff complaints

• Negative impressions from visitors

• Increased sickness absence

• Damage to flooring and furniture

• Time spent chasing missed tasks

• Frequent contractor changes

These hidden costs rarely appear on an invoice, but they can have a significant impact on your business.

Why a Site Survey Is Essential

Any professional cleaning company should visit your premises before providing a quotation.

During the survey they can assess:

• Floor types

• Washrooms

• Kitchens

• Number of workstations

• Meeting rooms

• Touchpoints

• Waste requirements

• Access arrangements

Without seeing the building, any quotation is largely an estimate.

A site survey allows the contractor to recommend a cleaning schedule that reflects your actual needs rather than making assumptions.

Investing in Quality

Commercial cleaning isn't simply another overhead.

It's an investment in your business.

A clean workplace creates a positive impression, supports employee wellbeing and helps maintain your premises for years to come.

When viewed this way, value becomes far more important than simply finding the lowest monthly price.

Final Thoughts

There is no fixed price for commercial cleaning in London because every business has different requirements.

The right cleaning contractor will take the time to understand your premises, recommend an appropriate cleaning schedule and provide a transparent quotation that clearly explains what's included.

When comparing quotations, look beyond the headline figure. Consider the experience of the company, the quality of its staff, the level of supervision and the overall service you'll receive.
