Understanding commercial cleaning costs in Australia

The two ways commercial cleaning is priced

Commercial cleaning in Australia is quoted either per square metre or per labour hour, and knowing which one you are looking at is the first step to comparing anything. Per-square-metre pricing for regular contract work sits at roughly $2.50 to $5.50 per m² per month for offices and retail, $1.20 to $2.50 for warehouse and light industrial, and $6 to $12 for medical, childcare and other high-compliance sites. Hourly pricing runs $38 to $55 an hour for daytime work, $45 to $65 for evening, and $60 to $85 for overnight, weekend and public holiday work where award penalty rates apply. Most contractors quote you a monthly figure derived from an hourly build-up, so asking for the assumed hours and headcount behind the monthly number is the fastest way to see whether a cheap quote is efficient or simply thin.

Why site type changes the rate so dramatically

Floor area alone is a poor predictor of cleaning time, because what matters is touch density and compliance burden. A warehouse is thousands of square metres of hard floor that a ride-on scrubber covers quickly, with a handful of amenities and almost no touchpoints, so it is cheap per square metre. A medical centre is the opposite: small area, dozens of touchpoints per room, colour-coded equipment to prevent cross-contamination, documented schedules that survive an accreditation audit, and separate handling for any regulated waste stream. Childcare sites carry similar documentation requirements plus toy and surface sanitising. Gyms sit in between, with high touchpoint density, sweat-related odour management and equipment that needs specific product. The same 400 m² can therefore range from $500 to $4,000 a month depending purely on what happens inside it.

After-hours loading is a real cost, not a markup

Cleaning is covered by the Cleaning Services Award 2020, which sets penalty rates for evening, overnight, weekend and public holiday work. Those loadings flow directly into your contract price, which is why a site requiring overnight service costs 30 to 50 per cent more than the same site cleaned during business hours. It also explains a common trap: a contractor who quotes overnight access at daytime rates is either underpaying staff, which becomes a reputational and legal risk for you as the principal, or has not properly understood your access constraints and will come back for a variation within the first quarter. When you brief a tender, state your access window precisely, because that single detail moves the price more than most operators' efficiency differences do.

Frequency, and the tiered schedule that saves money

Most sites are over-serviced in some areas and under-serviced in others, because the default contract applies a single frequency everywhere. The efficient structure is tiered: daily service for amenities, kitchens, entries and any client-facing space; two or three days a week for general office floors and meeting rooms; and weekly for storage, plant areas and low-traffic corridors. This routinely removes 15 to 25 per cent of the labour hours with no visible drop in standard, because the removed hours were being spent vacuuming empty rooms. The catch is that a tiered schedule must be documented task by task and area by area, otherwise it degrades into whatever the cleaner has time for.

What sits outside the base contract

Periodic work is the part of commercial cleaning most likely to be quietly skipped, because it happens infrequently enough that nobody notices its absence until the floor looks tired. Hard floor strip and seal runs $8 to $18 per m² and is typically annual or biannual. Commercial carpet steam cleaning is $3 to $7 per m², usually quarterly or twice yearly in high-traffic areas. High-level dusting, internal glass, and vent and diffuser cleaning are each their own cycle. Consumables supply and waste handling are separate again. Insist each periodic appears as a dated, priced line item you can verify against an invoice, rather than being absorbed into a flat monthly fee where it becomes invisible.

Contract structure, insurance and the things that bite later

Before signing, confirm three documents exist: a current public liability certificate, generally $10 to $20 million for commercial work, current workers compensation cover, and site-specific safe work method statements for anything involving heights, chemicals or machinery. Confirm also who supplies equipment, who is responsible if a floor finish is damaged by the wrong product, and what the response time is for a callback. Term length is worth negotiating: twelve months typically buys a 5 to 10 per cent discount because it lets the contractor roster permanent staff instead of casuals, and permanent staff produce measurably more consistent work. Pair that term with a 30 day termination-for-cause clause so the discount does not become a trap.

Comparing quotes without getting fooled

The single most useful request in a commercial cleaning tender is this: give me your assumed cleanable area, your assumed labour hours per week, your crew size, and your hourly build-up. Contractors who have measured the site will answer immediately. Contractors who have eyeballed it will not, and their number will drift within two quarters. Once you have those figures, the comparison becomes arithmetic rather than guesswork, and the differences that remain will be genuine differences in method, staffing model or scope. Use the estimator above to establish the bracket you should expect, then treat any quote 30 per cent or more below the field as a scope or staffing question rather than a saving.
