What Commercial Cleaning
Actually Covers.

A scope of works is the document that turns a vague promise into a contract. It names every area of the site, every task performed in that area, and the frequency of each task. Reception, open-plan floor, meeting rooms, kitchen, washrooms, stairwell, dock, crib room — each gets its own list. Without it, cleaning is whatever the cleaner has time for on the night, and nobody can prove otherwise.

Frequencies matter as much as tasks. Bins emptied daily, hard floors mopped daily, carpet vacuumed daily in traffic lanes and fully weekly, high dusting monthly, carpet extraction six-monthly, hard-floor machine scrub quarterly. Written that way, everyone knows what should have happened on any given visit, and periodic work stops being something that will get done eventually.

The scope should also record what is excluded. Exterior windows above ground level, waste bin collection to the kerb, kitchen dishwashing, personal desk items, biohazard response and specialist plant cleaning are all commonly assumed to be included and commonly are not. Writing exclusions down is not defensive; it is what prevents the argument in month three.

Finally, the scope should name access conditions: keys, alarm codes, dock bookings, lift access, restricted areas, and what the cleaner does at the end of the shift. On a multi-tenant site, that section is frequently longer than the cleaning tasks themselves.

Most commercial cleaning is sold as a periodic service charge — a fixed monthly or four-weekly fee covering the scheduled scope — with additional work quoted separately. Periodic tasks such as carpet extraction or floor sealing may be built into the monthly figure and delivered on a calendar, or quoted as they fall due. Both are legitimate; what matters is knowing which one you have signed.

Contract length varies widely across the market. Long lock-in terms with automatic rollover and exit fees are common, and they exist to protect the contractor rather than the client. A month-to-month agreement puts the pressure where it belongs: the contractor keeps the site by maintaining the standard, not by holding paperwork over you.

Watch how price increases are handled. A contract that allows unilateral annual increases without a corresponding change in scope is a contract that will get more expensive without getting better. Reasonable structures tie increases to award wage movements and state them in advance, with any scope change quoted separately.

Consumables are the other structural question. Hand soap, paper towel, toilet paper and bin liners can be supplied and charged by the contractor, or bought by the client and simply installed by the cleaner. Contractor supply is more convenient and stops the site running out; client supply is usually cheaper. Decide deliberately rather than discovering it on an invoice.

Ask for the scope before the price. Any contractor can produce a lower number by quietly documenting less work, and a quote with no scope attached is not comparable to anything. When you are comparing three proposals, normalise them against a single scope you wrote, not against three different ones the contractors wrote for themselves.

Ask who performs the work. Large parts of the Australian cleaning market are subcontracted two or three layers deep, which is how a site ends up with a different unvetted person every fortnight and nobody accountable for the standard. Ask whether cleaners are directly engaged, whether they are police-checked, and what staff turnover looks like on comparable sites.

Ask to see current certificates of currency for public liability and workers compensation, plus safe work method statements for any higher-risk task on your site. A contractor who cannot produce these on request is a liability that sits with the building owner, not with the cleaner.

Ask how quality is measured. A monthly audit against the written checklist, a named contact rather than a call centre, and a stated rectification timeframe are the difference between a cleaning contract and a cleaning relationship. Then ask what happens when the standard slips twice — the answer tells you more than any reference will.

The most expensive mistake is buying on hourly rate. Cleaning is bought by outcome, not by time, and an hourly comparison rewards the contractor who allocates the fewest hours. Two quotes at the same hourly rate can represent wildly different amounts of actual work, which is precisely why the scope has to come first.

The second is under-servicing floors to save money on the monthly invoice. Carpet that is not vacuumed frequently enough wears out years early because grit acts as an abrasive underfoot, and vinyl that is never machine scrubbed and resealed eventually needs stripping — an exercise that costs many times the maintenance it replaced. The cleaning line went down; the capital line went up.

The third is failing to plan the handover when changing contractors. Terminating the incumbent before the replacement has keys, codes, inductions and contractor-portal approval produces a week with no cleaner. Run the new contractor's onboarding in parallel and give notice only once access is arranged.

The fourth is treating the first month as settled. The standard on a new site is set in the first four weeks. Audit closely at the start, raise every deviation, and the habit forms correctly; leave it and you will be renegotiating a standard rather than enforcing one.
