How Much Does Commercial Cleaning Cost in London?

If you've started looking for a commercial cleaning company, you've probably asked the same question that almost every new client asks us:

"How much is commercial cleaning going to cost?"

It's an understandable question. Whether you're managing a busy office, a medical practice, a school or a retail premises, every business has a budget to work within. Cleaning is an essential service, but it's also one that businesses naturally want to get right without overspending.

The challenge is that there isn't a standard price.

Over the years, we've carried out site surveys in everything from small serviced offices with just a handful of employees to multi-storey commercial buildings with hundreds of staff. We've also worked with dental practices, GP surgeries, nurseries and schools—each with completely different cleaning requirements.

One thing we've learnt is this: two buildings that look almost identical on paper can require very different amounts of cleaning.

That's why one company might quote £600 per month while another quotes £1,000 for what appears to be the same job.

In this guide, we'll explain what influences commercial cleaning costs in London, why prices vary, and how to make sure you're comparing quotations fairly.

There Isn't a Fixed Price—and That's a Good Thing

Some services have a fixed cost. Commercial cleaning isn't one of them.

Imagine taking your car to a garage and asking, "How much will it cost to fix?" The mechanic's first response would probably be, "What's wrong with it?"

Commercial cleaning works in much the same way.

Before any reputable cleaning company can provide an accurate quotation, they need to understand your premises and your expectations.

For example:

• How many people use the building each day?

• Are there kitchens and staff break rooms?

• How many washrooms need cleaning?

• Is there carpet, hard flooring or both?

• Are there meeting rooms, treatment rooms or communal areas?

• Does cleaning need to take place during the day or after hours?

These details all influence how much time is required to clean the premises properly.

The Biggest Factors That Affect Commercial Cleaning Costs

The Type of Business

One of the biggest influences on price is the type of premises being cleaned.

A small office where employees spend most of the day at their desks has very different requirements from a busy dental practice or GP surgery.

Healthcare settings require enhanced infection control procedures, careful disinfection of high-touch surfaces and strict colour-coded cleaning methods to reduce the risk of cross-contamination.

Schools and nurseries bring their own challenges. Children naturally touch everything, which means tables, chairs, toys, door handles and washrooms need far more frequent attention.

Retail premises, on the other hand, are judged by customers the moment they walk through the door. Clean floors, spotless glass and well-maintained washrooms all contribute to the customer experience.

Each environment requires a different approach, and that affects the amount of labour involved.

Cleaning Frequency

Many businesses assume reducing cleaning visits automatically saves money.

Sometimes it does.

Sometimes it creates bigger problems.

We've visited offices that reduced cleaning from five evenings a week to twice a week in an effort to cut costs.

At first, everything seemed fine.

A few weeks later the complaints began.

The kitchens became untidy.

Washrooms never quite felt clean.

Dust started building up around workstations.

Bins overflowed before the next scheduled visit.

Eventually the business paid for a deep clean just to get things back to an acceptable standard.

Regular cleaning often proves more cost-effective because dirt doesn't have time to build up.

Size Isn't Everything

People often ask whether cleaning companies charge by square footage.

The answer is—not usually.

Floor area is certainly important, but it's only one part of the picture.

A 2,000-square-foot office with one kitchen and one toilet may take less time to clean than a smaller medical practice with six consulting rooms, treatment areas and multiple washrooms.

Professional cleaning companies calculate the number of labour hours needed to maintain the required standard rather than relying solely on the building's size.

What Does a Commercial Cleaning Contract Usually Include?

This is where many businesses make the mistake of comparing prices without comparing what's actually included.

A professional cleaning contract will usually cover:

• Fully trained cleaning operatives

• Cleaning supervision

• Commercial-grade equipment

• Cleaning chemicals

• Microfibre cloths and mops

• Routine quality inspections

• Public Liability Insurance

• Employers' Liability Insurance

• Holiday and sickness cover

• Ongoing contract management

Some companies also include stock management for washroom consumables, while others provide this as an additional service.

If a quotation seems significantly cheaper than others, it's worth asking what's been left out.

Why Are Some Quotes So Much Lower?

One of the most common questions we're asked is why quotations can vary so much.

The answer often comes down to time.

Imagine two companies quoting for exactly the same office.

One allows three hours each evening.

The other allows just ninety minutes.

Naturally, the second quotation will be cheaper.

But will the cleaner realistically have enough time to vacuum, dust, sanitise desks, clean kitchens, disinfect washrooms, empty bins and mop the floors to a professional standard?

Probably not.

When cleaning schedules become unrealistic, corners are inevitably cut.

It's rarely because cleaners don't care.

It's because they've simply been given too little time.

Cheap Cleaning Can Become Expensive

Every business wants good value.

That's sensible.

But value and low cost aren't always the same thing.

Poor cleaning standards can lead to:

• Increased staff complaints

• Unpleasant washrooms

• Poor first impressions for visitors

• Faster wear and tear on flooring

• Reduced staff morale

• Additional deep cleaning costs

Replacing a cleaning contractor every few months also consumes valuable management time.

Choosing a reliable company from the beginning often proves to be the more economical decision.

Why a Site Survey Matters

If a cleaning company provides a fixed quotation without seeing your premises, be cautious.

A proper site survey allows them to understand:

• Your cleaning priorities

• Access arrangements

• Security procedures

• Building layout

• Floor finishes

• Occupancy levels

• Specialist requirements

It also gives you the opportunity to ask questions and decide whether they're the sort of company you want to work with.

A good quotation should be based on facts—not guesswork.

How to Compare Cleaning Quotations

When reviewing quotations, don't just look at the monthly figure.

Ask yourself:

• How many hours of cleaning are included?

• Are cleaning materials supplied?

• Is supervision included?

• What happens if the regular cleaner is absent?

• Are quality inspections carried out?

• Are the cleaners directly employed?

• Is the company insured?

Sometimes the slightly higher quotation offers considerably better value over the life of the contract.

Frequently Asked Questions

How much does commercial cleaning cost in London?

Most commercial cleaning contracts in London are priced according to the number of labour hours required and the complexity of the premises. Costs vary depending on the building, the frequency of cleaning and the level of service required.

Is commercial cleaning charged per hour?

Many companies calculate quotations using an hourly rate, but clients are usually provided with a fixed monthly price based on the agreed cleaning schedule.

Are cleaning materials included?

Most professional commercial cleaning companies include cleaning chemicals and equipment within their quotations. Consumables such as toilet rolls, hand soap and paper towels may be charged separately.

How often should an office be cleaned?

Busy offices generally benefit from daily cleaning, while smaller workplaces may only require cleaning two or three times each week. The right schedule depends on occupancy, footfall and how the building is used.

Final Thoughts

Commercial cleaning isn't simply another business expense—it's an investment in your workplace, your employees and the impression you leave on clients.

The cheapest quotation isn't always the best choice, and the most expensive isn't always the right one either.

The key is finding a cleaning company that understands your business, provides realistic cleaning schedules and delivers consistent standards you can rely on.
