Search for commercial cleaning cost, office cleaning quotes, office cleaning prices, cost per hour or cost per square foot, and you will find a lot of numbers presented as if they apply to every building. They do not. Office cleaning cost is not a single figure, it is a calculation built from several variables that stack together, and a fair quote reflects your specific building rather than a national average.
This guide does not invent a price list, because doing so would be misleading. Instead it explains the mechanics: what drives the base rate, how specification changes the total, why frequency matters more than most people expect, how floor area is used, and what periodic extras get added on top. Every commercial job we quote is looked at on its own merits and priced on floor area and access, with a free, site-based quote rather than a guessed figure over the phone.
The short version
- Cost is built from hourly rate, specification, frequency, floor area and periodic extras
- A higher hourly rate with fewer hours can cost less overall than a cheap rate with padded time
- Specification changes the total more than most people expect
- Frequency does not scale the price in a straight line, because setup time is fixed
- Quotes should always be free and based on the actual site, not a phone guess
The building block: hourly rate
Somewhere underneath every commercial cleaning quote is an hourly or per-visit rate, even when the final figure presented to you is a flat monthly price. That rate reflects staffing costs, insurance, management and the contractor's own overheads.
Comparing two quotes on hourly rate alone is misleading, because the number of hours allocated to your building matters just as much as the rate charged for each one. A lower rate combined with more hours than the job actually needs can cost more overall than a higher rate applied efficiently.
How specification changes the total
Specification is the list of tasks included in a visit, and it is the single biggest lever on price after the building itself. A visit that covers bins, toilets and floors is a different job to one that also includes kitchen deep cleaning, internal glass, and touchpoint sanitising on every visit.
It is worth being precise about specification before comparing quotes, because two prices that look close on paper can represent very different amounts of actual work. A cheaper quote with a thinner specification is not automatically worse, but you should know that is what you are comparing.
- Core specification: toilets, kitchens, general floors, bins, touchpoints
- Extended specification: glass, high level dusting, deep kitchen work
- Periodic specification: carpets, hard floor maintenance, window cleaning
Why frequency does not scale in a straight line
It is tempting to assume that cleaning twice a week costs exactly double cleaning once a week, but it usually does not. A meaningful part of every visit is setup: getting equipment in, checking the site, and packing away at the end. That time is broadly fixed regardless of how long the actual cleaning takes.
That means increasing frequency generally costs less per visit than the first visit did, because setup time is shared across more visits over the same period. It also means very infrequent cleaning, such as once a fortnight, can look expensive per visit precisely because setup cost is not being spread out.
How floor area is used in a quote
Floor area, usually expressed in square metres or square feet, gives a rough sense of how long a visit should take for a given specification, but it is a starting point rather than the whole answer. Two identical floor areas can take very different amounts of time depending on layout.
Open plan space with few obstructions cleans faster per square metre than the same area broken into many small rooms, corridors and separate toilets, because more of the time goes into detail work rather than covering open floor.
Access: the factor people forget to mention
Access affects price as much as size in many buildings. Parking near the entrance, a dedicated lift, and flexible timing all make a job quicker to service. A shared lift with a booking system, restricted parking, or a strict access window all add time that has nothing to do with the cleaning itself.
Out of hours cleaning, covered in more detail in our separate guide, also affects cost because working outside normal hours can involve keyholding, alarm arrangements and lone working considerations that a daytime visit does not.
Periodic extras and how they sit alongside the core price
Carpet cleaning, upholstery cleaning, hard floor scrubbing and resealing, and window cleaning are almost always periodic rather than part of the routine visit, and they are usually priced and scheduled separately. That keeps the core routine quote clean and comparable, while periodic work is quoted on its own cycle.
It is worth asking upfront whether a quote includes any periodic work or whether it is purely the routine visit, since leaving this ambiguous is a common source of surprise invoices later.
Why quotes should be based on the site, not a phone call
A number given over the phone without seeing the building is, at best, an estimate based on averages that may not apply to you. Commercial cleaning quotes should be based on floor area and access as actually seen on site, which is why a proper quote is usually free and involves a visit rather than a guess.
This protects you as much as it protects the cleaner. A quote built on a real look at the space is far less likely to change once work starts, because there are fewer surprises left to discover.
What to have ready before you ask for a quote
Being ready with a few facts speeds the process up and helps you get a genuinely comparable figure from more than one company.
- Approximate floor area and number of rooms, toilets and kitchens
- Current cleaning frequency, or how often you think you need it
- Access details: parking, lifts, keys, alarm codes, timing restrictions
- Whether you want periodic work such as carpets or windows included
- Any specific compliance requirements for your industry
Comparing quotes fairly
Once you have quotes from more than one company, line them up against specification, frequency and what is included as periodic work rather than against the headline figure alone. The cheapest quote on paper is only genuinely cheaper if it covers the same ground as the others.
If in doubt, ask each company to confirm in writing exactly what is and is not included. A company confident in its pricing will not hesitate to put that in writing.
