Why a per-metre figure
rarely tells the full story.
A dollar-per-square-metre number is a common way cleaning is discussed, but on its own it hides more than it reveals. Here is what it can and cannot tell you.
What a per-square-metre rate actually measures
A cost-per-square-metre figure is simply the total cleaning cost divided by the floor area. It is easy to calculate and easy to compare, which is exactly why it gets used so often in early conversations about cleaning cost. The problem is that it compresses several genuinely different variables into a single number, and two very different jobs can produce an identical figure.
A fortnightly light tidy of an open-plan warehouse floor and a daily full-service clean of a densely partitioned medical centre could both work out to a similar rate per square metre, despite being nothing alike in labour hours, frequency or complexity. The metric does not distinguish between them.
That does not make it useless — it is a legitimate way to sanity-check quotes for the same building, or to compare very similar sites. It is just not a reliable way to estimate cost for a site you have not scoped, or to compare across genuinely different building types.
This is the core reason floor area alone never sets a price — frequency and scope carry at least as much weight.
What a per-metre figure hides.
Frequency
A rate quoted per square metre says nothing about whether that covers a daily, weekly or fortnightly service — three very different amounts of actual cleaning.
Scope
A basic tidy and a full sanitising service covering kitchens and bathrooms can produce the same per-metre number despite being fundamentally different jobs.
Layout
An open-plan floor and a heavily partitioned one of the same area take different amounts of time to clean, which a flat area-based rate cannot capture.
Site Type
A warehouse, a medical centre and a retail floor of the same size have entirely different cleaning requirements, which a single per-metre benchmark cannot meaningfully compare.
Access Conditions
After-hours work in a secured building costs more to deliver than daytime work in an unrestricted one, regardless of floor area.
How we actually quote, instead.
Scope Before Number
We establish frequency, tasks and site type before ever discussing a figure, because the number only means something once the scope is fixed.
Written, Itemised Quotes
Frequency, scope and consumables are set out clearly, so you can see what is actually driving the total rather than a single blended rate.
Comparable Across Similar Sites
For clients managing several similar sites, we can show a consistent per-metre figure across them once scope is held constant — a legitimate use of the metric.
No Guesswork Sold as Precision
We will not quote a per-metre rate before understanding your site, because doing so would be presenting a guess as a precise figure.
Where a per-square-metre figure is genuinely useful
The metric earns its keep in one specific situation: comparing quotes for the same building, or genuinely similar buildings, where frequency and scope are held constant. If you are comparing two contractors' quotes for exactly the same office, at exactly the same frequency and scope, dividing each by floor area gives you a fair like-for-like comparison.
It is also reasonably useful for a portfolio manager overseeing several very similar sites — say, a chain of similar-format retail stores — to spot an outlier once scope is standardised across them.
Where it breaks down
The metric fails the moment you try to use it to estimate an unknown site, or to compare across different building types, frequencies or scopes. A per-metre figure sourced from a fortnightly warehouse tidy tells you nothing reliable about what a daily medical centre clean should cost, even though both are commercial cleaning.
It also fails silently — because the number looks precise, it is easy to mistake it for more information than it actually contains. A single dollar figure per square metre cannot show you whether it assumes daily or fortnightly service, or whether bathrooms are included.
Why we do not quote from a per-metre rate card
Publishing a flat per-square-metre rate would mean pricing every site as if it were the average site — which would overcharge some clients and undercharge others, since it ignores frequency, scope, layout and access conditions entirely. Instead we quote each site individually once we understand what is actually needed.
This takes a short walk-through or floor plan review rather than a quick calculation, but it means the figure you receive reflects your actual site rather than a generic average.
A better way to compare quotes
Rather than asking each contractor for a per-metre rate, ask each to quote against the same defined scope — the same frequency, the same task list, the same consumables arrangement. Once that is fixed, the resulting total figures, and only then a derived per-metre number, are genuinely comparable.
Our page on general commercial cleaning cost factors sets out the variables worth holding constant across every quote you request.
How the metric is sometimes used to mislead
Occasionally a low headline per-square-metre figure is used to win a tender, with the actual scope quietly reduced to make it achievable — a lower frequency, fewer tasks, or consumables excluded. The number itself was not false, but the scope behind it was narrower than the buyer assumed.
The defence is simple: always ask what frequency and scope a quoted per-metre figure assumes, in writing, before treating it as comparable to any other quote you have received.
Cleaning Cost Per Square Metre — FAQs.
What is a normal cleaning cost per square metre?
There isn't a meaningful single figure, because the same square metreage can need vastly different amounts of work depending on frequency and scope. A number quoted without that context tells you very little about what your specific site would cost.
Is per-square-metre pricing a reliable way to compare cleaning quotes?
Only when frequency, scope and site type are identical between the quotes being compared. Used across different building types or service levels, it can be actively misleading.
Why won't you give me a flat rate per square metre?
Because a flat rate would have to assume an average frequency and scope that may not match your site, which risks either overcharging or underquoting the actual job. We prefer to quote against your real requirements.
How can I fairly compare quotes from different cleaning companies?
Ask each contractor to quote against the same defined scope — the same frequency and task list — rather than comparing raw totals or per-metre figures from quotes built on different assumptions.
Does a bigger site always cost proportionally more to clean?
Not necessarily. An efficient open-plan layout can cost less per square metre than a smaller, heavily partitioned space, because layout affects labour time independently of raw area.
