Ever tried to get a straight answer on what commercial cleaning should cost? If you’ve ever sought out cleaning quotes for your business, you might have felt like you were trying to solve a puzzle in the dark. One company quotes a low hourly rate, another offers a fixed monthly fee that seems exorbitant, and a third is somewhere in the middle, with a lot of confusing jargon in between.
It’s a common frustration. Why is there so much variation? And more importantly, how can you be sure you’re getting a fair price for a high-quality service?
The good news is that it’s not as complicated as it seems. A professional cleaning quote isn’t just a number plucked from thin air. It should be a careful calculation based on a clear set of factors related to your unique space and cleaning requirements.
As specialists in connecting businesses with trusted, vetted cleaning suppliers, we see these calculations every day. In this guide, we’ll pull back the curtain and show you exactly how professional cleaning quotes are put together. By the end, you’ll be able to read any quote with confidence and understand precisely what you’re paying for.
The Two Main Pricing Models: Time vs. Task
First things first, let’s look at the two most common ways cleaning companies structure their prices. Understanding these is the foundation for decoding any quote.
1. The £ Per-Hour Rate
This is the most straightforward model. You pay a set price for every hour a cleaner is on-site at your premises.
- What it is: A simple price, for example, £18-£25 per hour, per cleaner.
- When it’s used: This model is common for smaller offices, businesses that need less frequent cleaning (e.g. once a week), or jobs where the scope might change from visit to visit.
- The Pros: It’s easy to understand. If you need two hours of cleaning, you know exactly what the labour cost will be. It offers flexibility if you occasionally need an extra hour for a specific task.
- The Cons: The final cost can be less predictable. If a clean takes longer than anticipated due to an unexpected mess, your bill could be higher. It focuses on the time spent rather than the result achieved.
2. The Fixed Price (Per-Square-Foot or Per-Job)
Instead of paying for time, you pay a set price for the job to be completed, regardless of how long it takes. This fixed price is often calculated behind the scenes using a per-square-foot model, but it’s presented to you as a simple monthly or per-visit fee.
- What it is: A flat fee, for example, £1,000 per month for a daily clean of a medium-sized office.
- When it’s used: This is the standard for most ongoing commercial cleaning contracts, especially for medium to large businesses. It’s perfect for companies that need predictable budgeting and consistent results.
- The Pros: You get total cost certainty. Your bill is the same every month, making budgeting a breeze. The focus is on the outcome, as the cleaning company is obligated to complete the agreed-upon tasks to a high standard, regardless of the time it takes.
- The Cons: It can be less flexible for one-off requests, which might need to be quoted as a separate job.
Which is better? Neither is universally “better” as it all depends on your business. However, for most businesses seeking regular, reliable service, a fixed-price contract offers the best balance of quality, consistency, and budget control.
It’s All in the Details: What Really Shapes Your Cleaning Price?
Whether the final quote is hourly or fixed, it’s determined by a detailed assessment of the work involved. Think of it a bit like building a car: the basic model has a starting price, but every added feature, from leather seats to a bigger engine, adjusts the final cost.
Here are the core factors that every professional cleaning company will consider.
1. The Size and Layout of Your Space
This is the starting point. A sprawling 10,000-square-foot open-plan office will naturally cost more to clean than a cosy 1,000-square-foot startup office. But it’s not just about the raw square footage. The layout matters, too. An office with fifty small, individual rooms is more time-consuming to clean than a single open-plan floor of the same size, due to the extra time spent moving between rooms.
2. The number of “Busy” Zones
These areas are the heavyweights of any cleaning quote, areas such as kitchens and toilets. They require far more intensive work than general office space. Why?
- Hygiene: They are hotspots for germs and require thorough sanitisation of all surfaces, from taps and toilet seats to microwave handles and fridge doors.
- Specialist Products: They need a wider range of cleaning chemicals (descalers, disinfectants, glass cleaners) than other areas.
- More Tasks: Cleaning a washroom involves cleaning toilets, urinals, sinks, mirrors, floors, and restocking consumables like toilet paper, soap, and hand towels. A kitchen involves wiping counters, cleaning sinks, and often managing waste and recycling.
A business with one small washroom and a simple tea point will have a much lower cleaning price than a business of the same size with multiple large washrooms and a full-service canteen.
3. The Number of Desks and Staff
More people mean more activity, and more activity means more foot traffic, which requires more cleaning. A cleaning company will factor in the number of employees or desks because each one represents:
- A desk to be wiped down.
- A chair to be straightened.
- A computer monitor and phone to be dusted.
- A bin to be emptied.
An office with 50 staff members will generate significantly more daily dust, waste, and general mess than an office with 10 staff members, even if the physical space is the same size.
4. How Often Do You Need Us?
The frequency of the cleaning schedule is one of the most significant factors affecting your final quote. A daily clean is very different from a weekly one.
Think of it this way: a daily clean is a “maintenance” job. The cleaners are essentially resetting the office back to pristine condition after a single day’s use. A weekly clean is more of a “restoration” job, tackling a full five days’ worth of accumulated dust and dirt.
As a result, the price per visit for a weekly clean is typically higher than the price per visit for a daily clean. However, cleaning companies love consistent work, so they often offer frequency discounts. A contract for five days a week is more valuable and efficient for them to schedule than a single weekly visit, so the overall monthly cost reflects this with a better value rate.
- Daily Cleaning: Highest monthly cost, but lowest cost per visit. Best for busy, client-facing offices.
- 3 Times Per Week: A popular middle ground, balancing cost and cleanliness.
- Weekly Cleaning: Lowest monthly cost, but each visit is more intensive. Best for very small or low-traffic businesses.
5. Specialist Cleaning Services
Your standard cleaning quote will cover a defined list of tasks, often called the “specification.” This includes things like vacuuming, mopping, dusting, emptying bins, and cleaning washrooms and kitchens.
However, many businesses require additional services. These are almost always quoted separately as they require different equipment, training, and time. These can include:
- Window Cleaning (Internal & External): A specialist task, especially for high-rise buildings.
- Deep Carpet Cleaning: Using hot water extraction machines to remove deep-seated dirt.
- Hard Floor Polishing: Buffing and polishing floors to maintain their shine.
- High-Level Cleaning: Dusting hard-to-reach areas like vents, pipes, and light fixtures.
- Upholstery Cleaning: For office chairs and reception area sofas.
What a Good Professional Cleaning Quote Looks Like
Now that you know the ingredients, you can spot a quality quote. A transparent, professional quote should never just be a single number on an email. It should include:
- A Clear Scope of Work: A detailed list of all the tasks to be completed in each area of your office.
- Frequency and Timing: Clearly stating when the cleaners will be on-site (e.g. “Monday-Friday, after 6 pm”).
- A Clear Price: Broken down to show the cost per month and whether VAT is included.
- Proof of Insurance: Confirmation that the company holds Public Liability and Employers’ Liability insurance.
- Vetting and Training: Mention of their staff being vetted (e.g. DBS checked), trained, and employed directly.
- Consumables: A note on whether the price includes the restocking of items like toilet rolls and hand soap, or if this is an extra charge.
Getting a quote with this level of detail shows you’re dealing with a reputable company that values transparency.
