Commercial cleaning costs vary from site to site, so pricing is one of the first questions businesses ask us at Zenith Cleaning Service. It is a fair question, but many commercial cleaning companies avoid giving a clear answer, but we do.
This guide covers the market ranges we identified through our research for Adelaide and across Australia. It also explains how companies structure quotes, what can push your cost up or down, and how to spot a quote that may not legally cover the work at the price offered.
We do not publish fixed rates because we need to see the site before we quote. A price given over the phone is only an estimate and can lead to variations later. The figures below will help with budgeting and comparing quotes, but they are not our price list.
What Commercial Cleaning Costs in Adelaide
Commercial cleaning prices in Adelaide vary by site size, cleaning frequency, scope and facility type. Current 2026 pricing guides put standard commercial cleaning around these ranges:
Hourly Rates
- Standard office and commercial cleaning: $35 to $60 per hour
- Medical and specialised cleaning: $45 to $80+ per hour
- Deep cleaning and one-off work: often priced separately based on the size and scope of the job
Per Square Metre
- Regular office cleaning: around $2 to $4 per square metre per month
- Higher-specification work can cost more, depending on the site and scope.
Typical Monthly Contracts
- Small offices: around $250 to $600 per month
- Medium offices with daily service: around $800 to $2,500 per month
These are market estimates, not Zenith Cleaning’s rates. The final price depends on the site’s size, scope, cleaning frequency and access requirements. We assess each site before providing a fixed quote. Ask us for a quote based on the actual cleaning requirements.
The Three Ways Commercial Cleaning Is Priced
Knowing the pricing model makes it easier to compare quotes and understand what you are paying for.
- Hourly: You pay for the time spent on site. This suits small offices, flexible scopes, and one-off work. The main drawback is that a longer clean means a higher bill.
- Per Square Metre: You pay based on the size of the site, usually per clean or per month. This suits larger, open-plan sites, warehouses, and strata common areas. It can be less suitable for small sites with multiple bathrooms or kitchens.
- Fixed Contract: You agree on the cleaning scope and frequency, then pay a set monthly amount. This is common for ongoing office cleaning and gives you more predictable costs. For regular commercial cleaning, this is the model we generally recommend.
What Actually Shapes Your Quote
Six factors can change the price of commercial cleaning. Understanding them makes it easier to compare quotes.
Size of Your Site
Larger sites generally require more cleaning time, but floor area is not the only consideration. Room layout, furniture and high-effort areas can also affect the workload.
How Often You Need Us
Cleaning frequency directly affects the total cost. Daily service requires more visits than weekly cleaning, while the scope and cost of each visit can vary.
Scope of Work
A basic office clean differs from one that includes carpet care, windows, hard-floor maintenance and consumables. Make the scope clear when requesting quotes so you can compare like for like.
Type of Facility
Medical, industrial and food-related premises can require different cleaning methods, equipment and procedures. Clinical spaces can follow SA Health infection prevention guidance, while disinfectant requirements can involve the Therapeutic Goods Administration. These requirements can affect the scope and cost of medical cleaning. The same applies to food-related areas in restaurants and venues.
Access and Hours
After-hours, weekend and restricted-access sites can add to the cost. CBD buildings may also require loading-dock bookings, lift access or building inductions.
Washrooms, Kitchens and Consumables
Washrooms and kitchens can require more cleaning time than their floor area suggests. Consumables such as toilet paper, hand towels and soap may also sit outside the standard cleaning scope. Ask whether they are included in the quote.
How Cleaning Frequency Affects Your Total Cleaning Cost
Cleaning more often can increase the monthly cost, but it reduces the amount of work needed on each visit. Routine maintenance keeps dirt and build-up under control, whereas less frequent cleaning turns into recovery work that requires more intensive labour.
Stretching the cleaning schedule to save money moves the cost rather than removing it. Carpet that misses regular maintenance requires commercial extraction sooner. Vinyl that loses its protective finish needs stripping and resealing earlier. Preventing that premature wear is far less expensive than paying for restorative treatments later.
When comparing quotes, evaluate the cost per clean as well as the monthly total. Two providers can quote the exact same monthly figure at different visit frequencies without offering the same level of service.
What Periodic and Specialist Tasks Cost
Regular contracts cover ongoing maintenance, but specialised floor care and project work sit outside standard visits. Published Australian commercial market guides place these services around:
- Commercial carpet steam cleaning: $3 to $6 per square metre
- Vinyl hard-floor strip and seal: $8 to $15 per square metre
- End-of-lease and builder handover deep cleaning: $6 to $12 per square metre
Plan periodic work into your annual cleaning schedule rather than waiting until it becomes urgent. Carpet extraction and hard-floor maintenance can be scheduled separately as needed. For tenant handovers, end-of-lease cleaning can be quoted as an independent project to guarantee make-good compliance.
Why a Very Cheap Quote Should Raise Questions
If a quote comes in well below the market ranges above, check what the price actually includes before comparing the saving.
The Cleaning Services Award 2020 (MA000022) sets minimum pay rates and penalty rates for employees covered by the award. From 1 July 2026, the adult minimum hourly rates range from $27.08 to $29.45, depending on classification, before applicable penalty rates and other employment costs.
A cleaning company also has costs beyond wages, including superannuation, insurance, equipment, consumables, training, supervision and travel. A very low quote therefore deserves a closer look at the scope, hours and employment arrangements behind it.
Check whether the quote clearly covers:
- Award-compliant employment and pay
- The actual hours required to complete the scope
- Public liability and other relevant insurance
- Equipment and consumables
- Supervision and site management
- Any subcontractors involved in delivering the work
A low price does not automatically mean something is wrong. It does mean the scope, staffing and inclusions deserve closer attention before comparing it with another quote.
How to Compare Quotes Properly
Ask every provider the same seven questions. The answers separate them faster than price does.
- Is this a fixed price or an estimate? Ask what triggers a variation.
- What exactly is included, room by room and how often? Get the scope in writing.
- Are consumables in or out? Toilet paper, hand towel and soap add up.
- Are your cleaners employed by you or subcontracted? This drives both consistency and compliance.
- What insurance do you carry, and can I see the certificate? Public liability and workers compensation.
- Who is my point of contact, and how do I raise an issue?
- How do you verify the work was done? Supervisor sign-off, audits, testing, a logbook.
If a provider cannot answer questions four, five and seven, price is no longer the relevant comparison.

Frequently Asked Questions
How Much Does Office Cleaning Cost Per Hour in Adelaide?
Published Adelaide market guides for 2026 put recurring office cleaning at roughly $35 to $55 per hour per cleaner, depending on the site, scope and frequency. These are market estimates rather than Zenith Cleaning’s rates, since we provide a fixed quote after seeing the site.
Is Hourly or Per Square Metre Pricing Better?
Hourly pricing can suit smaller offices and changing scopes, while per-square-metre pricing can suit larger, open-plan sites. Fixed monthly contracts are also common for ongoing office cleaning, so compare the scope, frequency and inclusions rather than the pricing model alone.
Why Is One Quote So Much Cheaper Than the Others?
Check what each quote includes before comparing the price. Different cleaning hours, visit frequency, scope, consumables, access requirements and after-hours scheduling can all change the final figure. Compare like-for-like scope first, then compare the price.
Are Cleaning Supplies and Consumables Included?
Equipment and cleaning products are included in our service. Washroom and kitchen consumables such as toilet paper, hand towels and soap can be added to your schedule for an additional cost. Ask about these items specifically because providers can include or exclude them differently.
Can I Reduce My Cleaning Costs Without Losing the Required Standard?
Often, yes. Adjust the cleaning frequency according to how each area is used rather than reducing every task across the site. High-traffic areas, washrooms and kitchens may need more frequent cleaning, while lower-use areas can follow a different schedule.
Do You Charge More for After-Hours or Weekend Cleaning?
After-hours and weekend work can affect the quote because applicable award penalty rates may apply. The final price also depends on the cleaning schedule and site requirements. Zenith Cleaning operates seven days a week, including after-hours and weekend scheduling when required.
How Much Should I Budget for Periodic Work on Top of My Contract?
Plan for periodic work such as carpet extraction, floor maintenance and window cleaning separately from the regular contract. Current Adelaide guides put commercial carpet cleaning around $3 to $6 per square metre, while other periodic work depends on the floor, condition and scope. Sites using janitorial services can have periodic work scheduled according to actual site conditions.
