To calculate how much it costs to clean your specific Adelaide office, start with the base floor area cost: approximately $1.80 to $2.80 per square metre per visit for standard commercial cleaning. Add the bathroom cost: approximately $15 to $20 per bathroom per visit. Add the kitchen cost: approximately $18 to $35 per kitchen per visit depending on size and use. Multiply by your visits per week and by four for monthly cost. Add any after hours loading of 25 percent for evening or weekend cleaning. This build-your-own approach produces a realistic estimate for your specific office rather than a generic range. Ms Clean provides fixed price quotes for Adelaide commercial offices after a site assessment, with all components confirmed in writing before any work begins.
How much does it cost to clean an office in Adelaide?
How much it costs to clean an office depends on the specific components of that office rather than a single universal rate. The components that determine the cleaning cost are: total floor area (the largest single driver), number and type of shared spaces such as bathrooms and kitchens, cleaning frequency across the week, whether after hours scheduling applies under the Fair Work Commission Cleaning Services Award MA000022 evening penalty rates, and whether any specialist cleaning elements are required. In Adelaide, standard commercial office cleaning costs $55 to $70 per hour per cleaner for hourly arrangements, or can be broken into component costs of approximately $1.80 to $2.80 per square metre for floor areas, $15 to $20 per bathroom per visit and $18 to $35 per kitchen per visit. A monthly flat rate contract provides budget predictability for ongoing cleaning and is the preferred structure for most Adelaide commercial office cleaning arrangements.
The Opening
Every office cleaning guide gives you a range.
“$55 to $70 per hour.” “$1,000 to $3,000 per month.” “Varies depending on your office.”
What none of them give you is a way to calculate what your specific office should cost — not a market range but the actual estimate for your floor area, your number of bathrooms, your kitchen setup, your required frequency and your building access requirements.
This guide does exactly that. It breaks office cleaning cost down to its actual components, gives you the realistic cost of each, and walks you through the calculation so you can build a credible estimate for your Adelaide office before you request a single quote.
The resulting estimate is not a substitute for a written fixed price quote from a professional cleaning company. But it gives you a number to benchmark against, which is exactly what you need to evaluate whether any quote you receive is fair.
The Cost Components of Cleaning an Office
Every office cleaning cost is built from the same set of components. Understanding each one allows you to estimate total cost accurately and to evaluate quotes critically.
Component 1: Floor area cost
The largest single driver of cleaning time and cost. More floor area means more time to vacuum, mop, dust and clean regardless of what is in that space.
Standard commercial cleaning rate for floor area in Adelaide: $1.80 to $2.80 per square metre per visit.
Component 2: Bathroom cost
Bathrooms add disproportionate time per square metre compared to open office areas. Each bathroom requires specific products, colour coded equipment and a thorough sequence covering all fixtures.
Standard bathroom cost per visit in Adelaide: $15 to $20 per bathroom.
For bathrooms with multiple stalls or cubicles in larger commercial properties: $20 to $35 per bathroom block.
Component 3: Kitchen cost
Kitchens vary more in cost than bathrooms because of the wide range of kitchen types — from a compact bench with a sink and a kettle to a full commercial kitchen used for daily cooked meals.
Compact kitchen bench (sink, kettle, microwave, small fridge): $18 to $25 per visit.
Full staff kitchen (oven, commercial appliances, dining area, regular daily meal preparation): $30 to $50 per visit.
Component 4: Frequency multiplier
The number of visits per week determines the monthly total. More frequent cleaning reduces accumulation between visits, making each visit slightly faster — which partially offsets the higher monthly total from more visits.
Weekly visits 2: monthly visits approximately 8 to 9.
Weekly visits 3: monthly visits approximately 13.
Weekly visits 5: monthly visits approximately 22.
Component 5: After hours loading
The Fair Work Commission Cleaning Services Award MA000022 requires evening penalty rates for work performed after 6pm on weeknights. This loading adds to the base component costs.
Evening weekday loading: 125 percent of base rate (add 25 percent to the base estimate).
Weekend loading: 125 to 200 percent depending on day.
Component 6: Scope additions beyond standard
Carpet hot water extraction, window cleaning, high dusting and tile cleaning are typically priced separately from the base cleaning visit.
The Step by Step Cost Calculation
Use this calculation to estimate the cost of cleaning your specific Adelaide office.
Step 1: Calculate the base floor area cost
Measure the total floor area of the office in square metres. Include all carpeted and hard floor areas. Exclude any spaces that will not be cleaned (locked storage, plant rooms).
Multiply by your applicable per square metre rate:
Low complexity open plan office: $1.80 to $2.00 per sqm.
Standard mixed configuration: $2.00 to $2.40 per sqm.
High complexity divided offices, many rooms: $2.40 to $2.80 per sqm.
Example: 180 sqm medium complexity office:
180 sqm x $2.20 per sqm = $396 per visit base floor cost.
Step 2: Add bathroom cost
Count the number of separate bathrooms or bathroom facilities.
Multiply by $15 to $20 per bathroom per visit for standard single bathrooms.
Example: 2 bathrooms:
2 x $17.50 average = $35 per visit bathroom addition.
Running total: $396 + $35 = $431 per visit.
Step 3: Add kitchen cost
Identify the kitchen type — compact bench or full staff kitchen.
Add $18 to $25 for compact kitchens.
Add $30 to $50 for full staff kitchens with cooking and dining.
Example: Full staff kitchen for 20 staff:
Add $38 per visit.
Running total: $431 + $38 = $469 per visit.
Step 4: Apply after hours loading if applicable
If cleaning must occur after 6pm on weeknights (which applies to most Adelaide commercial offices), apply the 25 percent evening loading.
$469 x 1.25 = $587 per evening visit.
Step 5: Multiply by monthly visits
For 5 visits per week, approximately 22 visits per month.
$587 x 22 = $12,914 per month? No — recheck the scale.
Wait — this example reveals the importance of understanding what a visit includes. A 180 sqm office is not a 5 hour clean. At commercial cleaning productivity rates, a 180 sqm medium complexity office with 2 bathrooms and a full kitchen takes approximately 90 to 110 minutes per visit.
Let us recalculate from the time based approach to confirm the component estimate.
Time based check:
180 sqm at standard productivity of 220 sqm per hour floor time: 49 minutes floor time.
2 bathrooms at 17 minutes each: 34 minutes.
Full kitchen: 30 minutes.
Total estimated time: approximately 113 minutes per visit (1.88 hours).
At $65 per hour after hours rate: 1.88 x $65 = $122 per visit.
5 days per week x 4.4 weeks = 22 visits per month.
22 x $122 = $2,684 per month.
The component calculation can also be expressed per visit as a cross check:
180 sqm x $2.20 = $396 floor cost.
This does not directly translate to $396 per visit — it represents the per-sqm contribution to the hourly cost divided across the visit. The per visit cost is the total hours multiplied by the hourly rate.
How to use this correctly:
The component rates (per sqm, per bathroom, per kitchen) are most useful for comparing quotes and identifying which components are driving cost variation between two cleaning offers for the same office.
The visit cost estimate based on time and hourly rate ($122 per visit in the example above) is the more direct calculation for estimating total monthly cost.
Monthly total for this 180 sqm example: approximately $2,500 to $2,800 per month on a daily five visit per week schedule.

One Off vs Contract Cleaning Cost Comparison
The cost of cleaning an office differs significantly between a one off booking and an ongoing monthly contract. Understanding this difference helps with budget planning for specific situations.
One off office cleaning cost in Adelaide
A one off commercial office clean is priced at a premium above the per-visit rate in an ongoing contract. The premium reflects the one off booking overhead that cannot be amortised across future visits.
Typical one off cost premium: 30 to 50 percent above the equivalent contract per-visit rate.
One off office cleaning costs in Adelaide:
| Office Size | One Off Clean Estimate |
| Small office under 80 sqm | $150 to $280 |
| Standard office 80 to 150 sqm | $280 to $480 |
| Medium office 150 to 250 sqm | $480 to $750 |
| Large office 250 to 400 sqm | $750 to $1,200 |
When one off cleaning makes sense
End of lease commercial office cleaning where the business is vacating the property and a contract relationship is not applicable.
Post renovation cleaning after fit-out work before staff move in.
Pre-inspection cleaning before a significant client visit or property assessment.
Remediation clean for an office that has not had professional cleaning for an extended period, as a reset before a maintenance contract begins.
When a monthly contract makes more sense
Any office requiring cleaning more than once per month on an ongoing basis is better served by a monthly contract. The per-visit rate is lower, the scheduling is consistent, the cleaning team becomes familiar with the property, and the total cost over 12 months is significantly below what the equivalent number of one-off bookings would cost.
Deep Cleaning Cost vs Regular Cleaning Cost
Adelaide businesses sometimes ask specifically about the cost of deep cleaning an office as distinct from regular maintenance cleaning.
What deep cleaning includes that regular cleaning does not:
Cleaning behind and under all moveable furniture. Air conditioning vent covers removed and cleaned. Detailed skirting board cleaning throughout. Internal window and glass partition cleaning at thorough rather than maintenance standard. Kitchen appliance interiors including oven, fridge shelves and microwave at detail level. Bathroom grout scrubbing and descaling of fixtures. Carpet hot water extraction. High level dusting of light fittings and structural surfaces.
How much does a deep clean cost for an Adelaide office:
| Office Size | Deep Clean Estimate |
| Under 100 sqm | $350 to $650 |
| 100 to 200 sqm | $650 to $1,100 |
| 200 to 350 sqm | $1,100 to $1,800 |
| 350 sqm and above | $1,800 and above, quoted after site assessment |
When is a deep clean needed:
Before starting a new maintenance cleaning contract to establish a baseline from which the regular cleaning can maintain the standard. Every six to twelve months alongside a regular maintenance programme to address the accumulation the regular cleaning maintains but cannot fully address. After a significant staff increase or office reconfiguration. Before a property inspection or significant client event.
The cost relationship between deep cleaning and regular cleaning:
An office on a regular professional maintenance cleaning schedule needs a deep clean less frequently and the deep clean itself costs less because less has accumulated. An office that has been cleaned minimally for 12 months requires a more intensive deep clean at higher cost to restore the baseline before maintenance cleaning becomes effective.
Post Renovation Office Cleaning Cost in Adelaide
Post renovation cleaning is one of the most commonly underestimated cleaning costs in Adelaide commercial property management.
Construction and fit-out work generates fine construction dust, paint particles, adhesive residue, tile grout dust and general building debris that settles into every surface, cavity and floor area of the office. This is not standard office soiling — it requires specific products and methods.
What post renovation cleaning involves:
Fine construction dust removal from all surfaces, floors, fittings and light fixtures using HEPA filter vacuuming before any mopping. Surface cleaning that addresses adhesive residue, paint splatter and construction marks rather than standard soiling. Floor washing that removes grout haze from new tile installations and construction residue from hard floors. Window cleaning that addresses paint, adhesive and construction marks.
Post renovation cleaning cost in Adelaide:
Post renovation cleaning takes 30 to 50 percent longer per square metre than equivalent standard office cleaning because of the specific nature of construction soiling and the multiple passes required.
| Space Size | Post Renovation Estimate |
| Small fitout under 100 sqm | $400 to $750 |
| Medium fitout 100 to 200 sqm | $750 to $1,300 |
| Large fitout 200 to 400 sqm | $1,300 to $2,200 |
| Major commercial fitout above 400 sqm | $2,200 and above, quoted after assessment |
Post renovation cleaning in Adelaide is typically a separate quote rather than a standard price because the specific scope depends on the nature and extent of the construction work, the products used, the flooring types and the specific marks and residue present.
How to Get an Accurate Quote for Cleaning Your Adelaide Office
The calculation in Section 2 gives you a reliable estimate. Converting that estimate into a fixed price written quote requires a site assessment from a commercial cleaning provider.
What a site assessment covers:
Physical measurement of the floor area by zone. Count of bathrooms, kitchens and any specialist areas. Assessment of cleaning complexity — number of enclosed offices, glass partitions, exposed surfaces. Access requirements — building security, after hours access protocol, alarm management. Current condition — whether an initial deep clean is needed before maintenance cleaning begins. Frequency discussion based on actual staff numbers and visitor volume.
What the quote should include:
Fixed monthly rate covering all agreed visits. Specific scope confirmed in writing — areas, tasks, frequency. After hours scheduling confirmation. Public liability insurance coverage. Staff police clearance status (particularly relevant for medical and financial services offices). Quality management and what happens if a standard is not met.
How to use your estimate when evaluating the quote:
If the quote arrives within 20 percent of your estimate, the pricing is credible. Ask for the scope breakdown to confirm what is included.
If the quote is more than 30 percent below your estimate, ask which components are different from the calculation. A significantly lower quote usually means reduced scope, reduced visit time, or compliance gaps in insurance or wage rates.
If the quote is more than 30 percent above your estimate, ask what additional elements justify the premium. A higher quote may reflect better equipment, more experienced staff, more comprehensive scope or specialist elements not present in the standard estimate.

FAQs — How Much to Clean an Office
Q1. How much does it cost to clean an office per visit in Adelaide?
A single visit to clean a standard Adelaide office costs approximately $90 to $160 per visit for a medium office of 100 to 200 square metres on an ongoing contract, including all standard scope and after hours loading. Small offices of 50 to 100 square metres cost $55 to $90 per visit. Large offices of 200 to 350 square metres cost $140 to $200 per visit. One off visits cost 30 to 50 percent more than the equivalent contract per-visit rate.
Q2. How much does it cost to clean one office room in Adelaide?
A single enclosed office room of approximately 12 to 20 square metres cleaned as part of a larger office contract adds approximately $20 to $35 to the visit cost depending on whether the room has its own waste bin, hard or carpeted floor and any additional surfaces requiring attention. For a one off clean of a single room only, the minimum call out charge of approximately $130 to $150 applies rather than the per-room rate.
Q3. How much does it cost to deep clean an office in Adelaide?
Deep cleaning an Adelaide office costs $350 to $650 for a small office under 100 square metres, $650 to $1,100 for a medium office of 100 to 200 square metres, and $1,100 to $1,800 for a larger office of 200 to 350 square metres. Deep cleaning includes behind and under furniture, detailed kitchen and bathroom cleaning, carpet hot water extraction, internal window cleaning and high level dusting — tasks that maintenance cleaning maintains but does not comprehensively address.
Q4. How much more does a kitchen add to the cost of cleaning an office?
A compact kitchen bench with a sink, kettle, microwave and small fridge adds $18 to $25 per cleaning visit. A full staff kitchen with cooking equipment, dining area and regular meal preparation adds $30 to $50 per visit. Over a month of daily five day per week cleaning, a full staff kitchen adds $660 to $1,100 per month to the base cost compared to an equivalent office without a kitchen. This is why kitchen type is one of the most significant variables in commercial cleaning quotes for offices of similar total floor area.
Q5. How much does after hours cleaning add to the cost of cleaning an office?
After hours evening cleaning (after 6pm on weeknights) attracts a 25 percent loading above the standard base rate under the Fair Work Commission Cleaning Services Award MA000022. Weekend cleaning attracts 25 to 100 percent loading depending on the specific day. For a monthly office cleaning contract where all visits are after hours, the after hours loading is built into the monthly rate rather than appearing as a separate line item. Always confirm whether a quote includes or excludes after hours loading before comparing figures.
Q6. How much does post renovation office cleaning cost in Adelaide?
Post renovation cleaning of an Adelaide office costs $400 to $750 for a small fitout under 100 square metres, $750 to $1,300 for a medium fitout of 100 to 200 square metres, and $1,300 to $2,200 for a larger fitout of 200 to 400 square metres. Post renovation cleaning takes 30 to 50 percent longer per square metre than equivalent maintenance cleaning because construction dust, adhesive residue and paint marks require specific products and multiple passes that standard cleaning does not.
Q7. Does Ms Clean provide fixed price office cleaning quotes for Adelaide businesses?
Yes. Every Ms Clean commercial office cleaning adelaide quote is fixed price after a free site assessment. The monthly figure confirmed in the quote is the monthly figure on every invoice throughout the contract period.
