A commercial cleaning quote rises or falls with the time the scope needs and the cost of the hours it must be done in. The factors that move it most are what is included, how often it is done, when the cleaners can access the building, the type and layout of the space, the number of washroom fixtures and how heavily the space is used.
Scope: what is actually included?
The more tasks in the scope, the more time. Emptying bins and vacuuming is a short visit. Add kitchen cleaning, internal glass, high dusting and detailed washroom work and the time grows. Many price gaps between quotes come from one contractor leaving tasks out, so check what is written before comparing totals.
Frequency: how often?
Cleaning five nights a week costs more than three, but not in a straight line, because each visit has fixed set-up and travel time. Some tasks do not need doing every visit. Good scopes set frequencies task by task, with daily, weekly and monthly items, rather than one blanket frequency for everything.
Access: when can cleaners be there?
Evening, weekend and public holiday work attracts higher pay rates under the Cleaning Services Award, so a site that can only be cleaned at those times costs more than one with weekday access. Tight access windows, security procedures and lift or key logistics add time too.
Space type and layout
Different spaces clean at different speeds. Open-plan offices move quickly, private offices with furniture take longer, and clinical or education spaces have their own standards. Contractors time each space type separately instead of using one rate for the whole building, which is the approach behind published benchmarks such as ISSA's.
Washrooms
Washrooms are timed by fixture count, not size. Every toilet, urinal and basin is a fixture to clean, and ISSA's method works from about three minutes each. A building with several washrooms will cost noticeably more than the same floor area without them.
Traffic and occupancy
A space that is full all day needs more cleaning than a quiet one of the same size. Headcount, visitors, food in the building and how people use shared areas all change how much time a clean takes. Tell contractors honestly how busy the space is.
Standard, supplies and extras
A higher standard of finish takes more time. Who supplies consumables and equipment changes the price, and specialist work such as carpet extraction, floor sealing or high-level glass is usually quoted separately.
Putting it to use
When two quotes differ, check the scope, frequency and access assumptions first. Our guide to how commercial cleaning is priced explains the labour logic behind these factors, and writing a scope of work lets you control them. We check every one of these on a walkthrough before we quote: book yours.
