What Commercial Cleaning Covers in WA

Commercial cleaning divides into scheduled work and periodic work, and confusing the two is where most disputes begin. Scheduled work is the routine attendance, whether daily, several times a week or weekly, covering bins, kitchens, amenities, vacuuming, surfaces and glass at entry points. Periodic work is the less frequent specialist attention including carpet extraction, hard floor treatment, external windows, high dusting and upholstery. A contract that prices the scheduled work and stays silent on the periodic work is only half a contract. The gap surfaces about eight months in, usually when a visitor comments on the carpet.

The scope schedule is the document that actually governs the relationship and it deserves more attention than the price. A good schedule lists each area, each task, and the frequency for each, so both parties know whether the meeting room windows are cleaned weekly, monthly or never. A vague schedule saying the premises will be kept clean and tidy is unenforceable in any practical sense. When a client is unhappy with a cleaning contractor, the underlying cause is usually a schedule that never specified the expectation rather than a contractor failing to meet one.

Building type drives the specification far more than floor area does. An office needs presentation and amenity hygiene. A medical suite needs infection control practices and specific product selection. A childcare centre needs both, plus attention to surfaces at child height and to toys and soft furnishings. A warehouse needs dust control and safety-critical floor cleaning rather than presentation. A food premises has statutory obligations attached. Pricing all of these on a rate per square metre without adjusting the specification produces the wrong answer in most cases.

Perth's environment shapes the work in ways that surprise operators from wetter states. The long dry summer produces persistent fine dust that settles continuously on horizontal surfaces, so surfaces that would stay presentable for a week in Melbourne need attention more often here. Coastal sites carry salt film on glass and external surfaces. Sites near unsealed roads, construction or the northern iron ore regions deal with a far heavier dust load again. None of this is a contractor performance issue but it does need reflecting in the frequency.

Access arrangements determine both cost and practicality, and they should be settled before the contract starts rather than negotiated afterwards. Most commercial cleaning happens outside trading hours, which means keys or credentials, alarm codes, after-hours building access and often an induction. In managed buildings the contractor may need to be accredited by building management. Where cleaners hold access to a tenancy unsupervised, the arrangement intersects with the building's security systems and should be documented properly. Who holds which credential, how access is revoked when staff change, and what happens to keys at contract end all belong in writing rather than in somebody's memory.

Consumables are the quiet variable in almost every commercial cleaning quote. Toilet paper, hand towel, soap, bin liners and sanitary services may be included, charged separately, or excluded entirely, and comparing quotes without checking which is comparing different products. On a busy building the consumables cost is not trivial. Establishing whether they are in or out, and at what rate, prevents the most common invoice surprise in the first quarter of a new contract.

How Cleaning Contracts Are Actually Priced

Almost every commercial cleaning quote is built from hours rather than from square metres, even when it is presented as a rate per square metre. The contractor estimates how long the scope takes, applies a labour rate, adds consumables, equipment, insurance, supervision and margin, then divides by the area to produce a headline figure. Understanding this matters because it explains why quotes differ. A cheaper quote is nearly always fewer hours on site. Fewer hours means less work done rather than the same work done faster. There is no meaningful productivity gain available in mopping a floor, and anyone claiming otherwise is describing a shorter attendance.

Ask every tenderer to state the attendance hours their price is based on. This single question converts a set of incomparable numbers into a comparable set, and it is the most useful thing a client can do during a cleaning tender. A contractor proposing two hours a night for a floor that plainly needs three is either misunderstanding the scope or planning to underdeliver. One proposing four when others propose two may have read the scope more carefully, or may be gold plating. The hours figure lets you ask the question directly rather than guessing at the difference, which is the whole point of requesting it.

Frequency is the lever that moves cost most, and it is worth optimising rather than defaulting. Many offices are cleaned five nights a week from habit rather than need, particularly since hybrid working reduced occupancy. Three nights a week with amenities serviced daily is a common and effective compromise that reduces cost substantially without reducing perceived cleanliness. The areas that genuinely need daily attention are kitchens, toilets and bins. Desks and floors in a lightly occupied office often do not.

After-hours and weekend work carries loadings that flow directly from the applicable award, and this is not contractor margin. Weekend cleaning, early morning starts and public holiday attendance all cost more because the wages cost more. A client insisting on Sunday attendance should understand they are buying penalty rates. Where the requirement is genuine, the cost is justified. Where it is habit, moving the attendance to a weekday is an easy saving.

Periodic work should be scheduled and priced in the contract rather than quoted ad hoc each time. Carpet extraction, hard floor treatment, external window cleaning and high dusting all have sensible intervals, and building them into an annual programme spreads the cost predictably and ensures they actually happen. Left to be requested, periodic work is deferred until a visitor comments, at which point it costs more because the condition has deteriorated. An annual programme is both cheaper and produces a better building, and it removes the awkward conversation about whether the carpet clean is due.

Contract length and review mechanisms deserve thought at signing. Twelve months with an annual review is common and reasonable. Longer terms should carry a clear rise and fall mechanism tied to wage movements, because labour is the overwhelming majority of the cost and award rates move. A contract with no adjustment mechanism over three years either has padding built in for future increases, or has a contractor who will be seeking a variation. Neither is a good outcome. A transparent mechanism is better for both parties.

The WA Wage Position and Why It Matters to You

Western Australia has an industrial relations feature no other state shares, and it affects cleaning contracts directly. WA did not refer its private sector industrial relations powers to the Commonwealth, which means the state retains its own system. Whether a cleaning business falls under the national system or the WA state system depends on how it is structured. Incorporated businesses that are constitutional corporations generally fall under the national system. Sole traders, partnerships and other unincorporated employers in WA generally fall under the state system. Cleaning is an industry with a great many small unincorporated operators, which makes this distinction unusually relevant here.

The practical consequence is that two cleaning contractors quoting on the same building may be operating under different awards with different rates, loadings and conditions. This is not a loophole and both positions can be entirely lawful. It does mean that comparing quotes on price alone, without understanding what wage structure sits underneath, is comparing things that are not equivalent. Information on the WA state system is published through DMIRS, and it is worth a read before running a cleaning tender rather than after.

Underpayment is a genuine and well documented problem in contract cleaning nationally, and the reason is structural rather than moral. Cleaning contracts are won on price, labour is almost the entire cost, and the only way to be materially cheaper than a compliant competitor is to pay less than the award requires. A quote significantly below the market is worth interrogating rather than celebrating. The saving is coming from somewhere, and it is usually the cleaner's pay packet. This is not a reason to assume the worst of every cheap quote, but it is a reason to ask the question.

Clients are not entirely insulated from this. Under the accessorial liability provisions of federal workplace law, a person or business involved in a contravention can be exposed alongside the employer. Knowingly engaging a contractor at a rate that cannot support lawful wages is a risk, and the reputational exposure is separate again. Businesses with any public profile, government contracts or supply chain obligations should treat wage compliance as part of the procurement decision rather than an unrelated matter.

Practical due diligence is straightforward and most reputable contractors welcome it. Ask which industrial system and award the business operates under. Ask for the attendance hours and the labour rate. Ask whether cleaners are employees or subcontractors, and if subcontractors, how the arrangement works. Ask about supervision and turnover, since high turnover often signals underpayment. Requesting evidence of wage compliance at contract renewal is increasingly normal in the WA market and no longer treated as an unusual ask.

Subcontracting deserves particular attention because it is where accountability disappears. A contractor who subcontracts each site to an individual operator, who then engages family members, produces a chain where nobody is clearly the employer. This structure is common in the lower end of the market and it is where wage problems concentrate. It also creates practical difficulties around insurance, induction, security clearance and consistency of service. None of those is something a client wants to discover after an incident.

Chemicals, Working at Height and Safety Duties

Cleaning is a workplace and the Work Health and Safety Act 2020 applies in full, with duties shared between the cleaning contractor and the building occupier. The contractor is responsible for its workers, their training, their equipment and their safe systems of work. The occupier retains duties as the person controlling the workplace, including telling the contractor about hazards on site. Where both parties assume the other is handling something, gaps appear. Current guidance is published by WorkSafe WA, and a short site induction covering the building's hazards is a reasonable thing to insist on.

Chemical management is the duty most often handled poorly in small cleaning operations. Hazardous chemicals require safety data sheets, correct labelling on decanted containers, a register, appropriate storage, personal protective equipment and spill provisions. Decanting a concentrate into an unlabelled spray bottle is both common and non-compliant. On any commercial site the contractor should be able to produce safety data sheets for everything they bring in. Products from established suppliers such as Diversey, Ecolab and Agar are standard in Australian commercial cleaning and all carry readily available documentation. A contractor who cannot is telling you about their systems generally rather than about paperwork specifically.

Chemical selection also matters to the building rather than only to the cleaner. The wrong product damages finishes, and the damage is usually permanent and expensive. Acidic cleaners etch natural stone. Solvent-based products soften vinyl and some sealers. Bleach discolours grout and fabric. Aggressive alkaline products strip floor seals prematurely. A contractor who asks what the surfaces are before proposing a product regime is doing the job properly, and one who applies the same three products to everything is not.

Working at height is the highest-consequence risk in commercial cleaning and it is routinely underestimated. External window cleaning above ground level, high dusting in warehouses, light fitting cleaning and gutter work all involve height. Ladders have limits, and beyond them the correct equipment is an elevating work platform or a rope access system, both of which carry licensing and training requirements. A contractor proposing to clean second storey windows from a ladder leaning against the building is proposing an unsafe system of work, and the injury would happen on your premises rather than theirs.

High-rise external cleaning is a specialist discipline rather than an extension of ordinary window cleaning. Rope access work requires trained and certified technicians, documented rigging, anchor point certification and rescue planning. Buildings with permanent facade access systems need those systems inspected and maintained. This is why high-rise window cleaning at eight to twenty five dollars per pane costs multiples of ground floor work. The difference is compliance rather than opportunism, and a quote well below that band should prompt a question about method.

Manual handling and repetitive strain injuries account for a large share of cleaning industry claims, and equipment choice affects them directly. Ergonomic equipment, appropriately sized mop systems, back vacuums rather than upright units for large areas, and trolley design all matter. From a client perspective this shows up as insurance cost and staff turnover, both of which eventually reach the price. A contractor investing in equipment is generally a contractor with a stable workforce. Stability is worth more to a building than a small rate saving, because familiar cleaners make fewer mistakes and need less supervision.

Specialist and Periodic Work

Carpet in commercial buildings needs periodic extraction regardless of how well it is vacuumed, because vacuuming removes loose soil while extraction removes the bound soil that dulls the fibre. Hot water extraction at three dollars fifty to nine dollars per square metre is the common method, and encapsulation is an alternative where drying time is the constraint. Drying is the practical issue in an office, since carpet needs hours to dry and the building needs to be usable in the morning. Scheduling extraction on a Friday night is standard practice for this reason, and it should be agreed at contract stage rather than negotiated each time.

Frequency should follow traffic rather than the calendar. A busy entry lobby needs extraction several times a year while a rarely used meeting room may need it annually. Entry matting is the single most effective way to reduce carpet soiling and extends the interval between cleans substantially, which makes it a genuine cost saving rather than a nicety. Our carpet cleaning page covers the methods in more detail, including where encapsulation suits a building better than extraction.

Hard floors carry the added dimension of slip resistance, which makes the sealer choice a safety decision rather than an aesthetic one. Stripping and resealing at eight to twenty two dollars per square metre restores appearance, but a high-gloss finish on a floor that gets wet creates a genuine hazard. Entry areas, kitchens, amenities and any floor near an external door need slip resistance appropriate to the conditions. A contractor proposing the shiniest available finish for a cafe floor has prioritised the wrong outcome, and the consequence lands on the occupier rather than the contractor.

Different hard floor materials need different treatment and a contractor who treats them identically will damage something. Vinyl needs compatible sealers and gentle chemicals. Natural stone is vulnerable to acids and to some strippers. Polished concrete needs pH-neutral maintenance rather than aggressive products. Timber has its own regime entirely, and our floor sanding and polishing page covers restoration where maintenance has been neglected too long.

External window cleaning frequency in Perth is driven by dust and salt rather than rain, which means the intervals that work in eastern capitals are too long here. Coastal buildings develop a salt film that etches glass over time if left. Buildings near construction or unsealed roads accumulate dust quickly. Quarterly is a common commercial interval, with monthly for high-presentation retail and entry areas. Our window cleaning page covers the general approach.

Pressure washing handles external hard surfaces, loading docks, car parks, bin areas and building facades, and it is the service most likely to create an environmental problem if done carelessly. Our pressure cleaning and driveway cleaning pages cover the methods, and the runoff issue is addressed below. Coordinating pressure washing with gutter cleaning and other roof access work reduces the access cost across both. On buildings needing an elevating work platform, batching everything that requires one into a single visit is a straightforward saving, and it reduces the number of times the car park has to be closed.

Food Premises Cleaning and Kitchen Canopies

Cleaning in a food premises is a statutory obligation rather than a housekeeping preference. The Food Standards Code requires food premises to be kept clean and, where required, sanitised, with specific attention to food contact surfaces and equipment. Local governments enforce this through inspection, and a poor result affects the business's registration and increasingly its public rating. A cleaning contractor working in food premises needs to understand the distinction between cleaning and sanitising, because they are different processes with different products and different purposes.

Responsibility allocation between the operator and the contractor should be explicit in the scope schedule. Food businesses usually handle their own end-of-service cleaning of equipment and food contact surfaces, while the contractor handles floors, walls, amenities, bins and periodic deep cleaning. Where the boundary is unclear, the areas nobody claimed are the areas an inspector will find. Writing the split down is a five minute exercise that prevents a genuinely serious problem. It protects the contractor as much as the operator, since neither wants to be the party an inspector asks.

Kitchen exhaust canopy cleaning is a fire safety matter first and a hygiene matter second, and it is the most commonly neglected item in hospitality. Cooking deposits grease throughout the canopy, filters, ductwork and fan, and accumulated grease in a duct is fuel in a concentrated form with a heat source directly beneath it. Canopy fires spread into the duct and then into the building fabric, which is precisely why insurers take an interest. Cleaning costs four hundred and fifty to three thousand five hundred dollars depending on the system size and how long it has been left.

The scope of a proper canopy clean matters as much as the frequency. Cleaning the visible canopy and the filters is straightforward and is what a cheap service delivers. Cleaning the ductwork and the exhaust fan requires access panels, more time and specialist equipment, and it is where the accumulated grease actually sits. A certificate covering only the canopy and filters may not satisfy an insurer who expects the full system addressed. Check what the certificate actually covers rather than filing it unread.

Frequency should follow cooking type and volume rather than a default interval. A high-volume operation using deep fryers and char grills produces vastly more grease than a cafe doing sandwiches and coffee. Insurance policies frequently impose conditions specifying cleaning frequency and requiring evidence, and a claim following a kitchen fire will involve scrutiny of those records. Keeping the certificates filed with the building's other compliance records, alongside the fire compliance documentation, is the sensible arrangement.

Runoff, Chemical Disposal and Perth Groundwater

Pressure washing runoff entering the stormwater system is an environmental offence and it is treated more seriously in Perth than many operators realise. The reason is hydrological. Perth's stormwater is largely disposed of on site through soakwells and drainage basins that discharge into sandy soils above the groundwater the city depends on. Contaminated runoff does not travel to a treatment plant. It goes into the ground, and from there toward the aquifer that supplies a substantial share of the city's water.

This means the standard practice of washing a loading dock, a car park or a bin area and letting the water find the nearest grate is not acceptable on any commercial site. Runoff carrying detergent, oil, grease, food waste or sediment needs capturing and disposing of appropriately, whether to sewer under a trade waste arrangement or by collection. Contractors who work regularly in commercial understand this and bring containment equipment. Contractors who do not will create a problem the site owner ultimately answers for, because the obligation attaches to the occupier as well as to whoever held the hose.

Bin area and waste enclosure cleaning is the most common trigger for this problem and it happens weekly across Perth. These areas concentrate exactly the contaminants that should not enter groundwater, and they are the areas most likely to be hosed out casually. Where a site has a bin area needing regular washing, the correct arrangement is a graded area draining to sewer with trade waste consent rather than to the stormwater system. Our commercial plumbing page covers trade waste consent and how the arrangement is set up.

Chemical storage and disposal carry their own requirements. Concentrates need storing appropriately and securely, incompatible products need separating, and disposal of unwanted chemicals is not a matter of pouring them down a sink. Bulk quantities on site attract additional obligations. For most commercial cleaning contracts the quantities are modest, but the principle applies. The contractor should be able to explain their arrangements without hesitation, and a vague answer here usually accompanies vague answers elsewhere.

Waste handling is increasingly part of the cleaning scope and worth specifying deliberately. Who moves the bins, who separates recycling, who manages confidential waste and who deals with bulky items left in bin areas are all questions that produce friction when unassigned. Where the building generates significant waste, coordinating the cleaning contract with the rubbish removal arrangement produces a better outcome than running them as unconnected services. Bin presentation and collection timing in particular tend to fall between the two.

Healthcare, Childcare and Regional Sites

Healthcare and medical cleaning is a specialist discipline with its own methods, and general commercial experience does not transfer automatically. The work involves defined cleaning sequences, colour-coded equipment to prevent cross-contamination between areas, specific disinfectants with defined contact times, and documented procedures. Clinical areas, waiting rooms and amenities each have different requirements. A medical practice engaging a general office cleaner without specifying the standard is likely to receive office cleaning. That is not what a clinical environment requires, and the gap is not always visible until an audit.

Childcare cleaning combines infection control with the practical realities of an environment full of children. Surfaces at child height need the same attention as bench height. Toys, soft furnishings and sleeping mats need regimes of their own. Product selection matters more than in an office because children touch everything and put things in their mouths, so residues and fragrances are a genuine consideration. Centres also operate under regulatory oversight that includes hygiene, which makes the cleaning contract part of the compliance picture.

Aged care carries a similar combination of infection control and vulnerability, with the added complication that the building is somebody's home. Cleaning happens around residents rather than in an empty building, which affects timing, noise, chemical selection and the temperament required of the staff. Continuity of personnel matters far more here than in an office. A contractor with high turnover will struggle in aged care regardless of their technical competence, because residents notice unfamiliar faces and the relationship matters.

Regional and remote work across Western Australia operates on entirely different economics. Mobilisation, travel and accommodation costs appear as line items and on smaller sites can exceed the labour value. The contractor base is thinner, which reduces competitive tension and makes reliability more valuable than price. Batching work into planned visits rather than calling for individual attendances is the sensible approach, exactly as it is with every other trade in regional WA. Reliability is also worth paying for, since a contractor who does not turn up in Karratha cannot easily be replaced by Friday.

Mining and resource sector sites add a compliance layer that changes the cost structure. Site inductions, competency requirements, drug and alcohol testing regimes, camp accommodation protocols and client-specific standards all apply. Accommodation village cleaning is a substantial sector in its own right across the Pilbara and Goldfields, operating to rosters and standards quite unlike metropolitan commercial work. Contractors experienced in this environment price the overhead because it is real.

Environmental conditions in the north add practical difficulty that metropolitan schedules do not anticipate. Red dust in the Pilbara penetrates everything and returns within hours of cleaning. Coastal salt in the north west combines with heat to accelerate deterioration of surfaces and equipment. Cyclone season affects scheduling and access. A cleaning specification written for a Perth office and applied unchanged to a Karratha site will disappoint everyone involved.

Strata and Common Property Cleaning

Common property cleaning in strata titled commercial buildings is the strata company's responsibility under the Strata Titles Act 1985, covering entries, lobbies, corridors, stairs, lifts, car parks, bin areas and common amenities. Cleaning within an individual lot is the occupier's concern. The boundary is usually clearer here than with services like plumbing. The practical overlap around entries, shared amenities and bin areas still generates disagreement in schemes without a documented scope. The disagreement is rarely about money so much as about who noticed first.

Consolidating common property cleaning under one contract produces better results than leaving it to whichever occupier complains loudest. It gives the strata company a defined scope, a single accountable contractor, a budgeted annual figure and a consistent standard across the building. It also avoids the situation where three separate cleaners attend the same building on different days. Each does part of the work and none is responsible for the areas between. That is exactly where the building looks worst, and it is the first thing a prospective tenant sees on the way in. Consolidation solves it without costing more.

Car parks and bin areas are the common property areas most likely to be neglected and most likely to generate complaints. Both need periodic attention rather than routine daily cleaning, and both raise the runoff question discussed above. Building a periodic schedule for these areas into the annual programme, rather than responding to complaints, keeps the building presentable and spreads the cost predictably across the year. It also removes the argument about whether the work was needed.

External areas including entries, glazing, signage and landscaped surrounds shape how the building presents to visitors and tenants, and they are frequently outside everyone's assumed scope. A strata company that budgets for internal common area cleaning and never addresses the entry glazing or the facade is spending money without achieving the presentation it wants. Coordinating this with the building's periodic maintenance, including commercial painting cycles, makes the whole exterior programme more coherent. It also lets the strata company plan the spend rather than react to it, which reserve fund budgeting depends on.

What to Look Out For

Interrogate a quote that is materially cheaper than the others rather than accepting it. In a service where labour is almost the entire cost, a large price gap means fewer hours or lower wages, and neither produces a good outcome. Ask every tenderer to state the attendance hours their price assumes. This one question makes the quotes comparable. It also exposes the difference between a contractor who has scoped the building and one who has applied a rate per square metre without visiting.

Insist on a detailed scope schedule listing areas, tasks and frequencies before signing anything. A contract without one is unenforceable in practice, and it is the root cause of most cleaning disputes. Include the periodic work with its intervals, specify who supplies consumables and at what cost, and state what happens when the schedule needs to change. Reviewing the schedule against the building rather than accepting a generic template is worth the hour it takes, and the hour is usually the contractor's.

Ask directly about the employment arrangements, the applicable award and whether staff are employees or subcontractors. This is a reasonable procurement question and reputable contractors answer it readily. Given Western Australia's dual industrial relations system, also ask which system the business operates under, because it affects the rates underlying the price. Evasiveness on wage questions is the clearest warning signal available in this market. Ask the question directly.

Check the safety systems rather than assuming them. Ask to see safety data sheets for the chemicals used on your site, ask how working at height is managed and with what equipment, and ask what the contractor's insurance covers. If external windows above ground level are in scope, establish exactly how they will be reached. A contractor without a clear answer on height access is a contractor whose worker may be injured on your premises.

Get the arrangement in writing covering the scope schedule with frequencies, the attendance hours, consumables inclusion and rates, periodic work and its programme, the access and key arrangements, supervision and quality assurance, the process for reporting and rectifying issues, insurance evidence, the term and any rise and fall mechanism, and the notice period. Cleaning contracts are easy to enter and occasionally difficult to exit, so the termination terms deserve a read before signing. Automatic rollover clauses with long notice periods are worth spotting early. They are easy to miss and hard to exit once triggered.

How to Get Useful Quotes

Provide a floor plan and a description of use rather than only an area figure. The number of workstations, the number and type of amenities, whether there is a kitchen and how heavily it is used, the floor surfaces by area, the number of external glazed panes, and the occupancy pattern all change the work. A cleaning quote based on floor area alone is a rate applied to a number rather than an assessment of your building. The two look identical on paper and behave very differently in practice.

Be specific about frequency and hours from the outset, and be honest about what actually needs daily attention. If you want three nights a week with daily amenity servicing, say so and let contractors price it. If you are open to a recommendation, say that instead and ask each tenderer to propose a frequency with reasoning. The second approach often produces a better outcome, since a contractor who has walked the building may see the pattern more clearly than the client does. Ask for both.

Site visits are essential for anything beyond a small tenancy and any contractor pricing a commercial building without attending is guessing. The walk-through reveals the floor surfaces, the condition of the carpet, the amenity fitout, the bin arrangements, the access constraints and the areas that will take longer than the plan suggests. It also lets the contractor raise the periodic work the building plainly needs, which a plan will never show. Carpet condition in particular is invisible until someone stands on it.

Putting the brief through The Quote Yard reaches several WA cleaning contractors with the same information, which makes proposals comparable in a market where comparability is unusually difficult. For one-off requirements our bond cleaning and general cleaning services pages cover the scope, and businesses completing a fitout should also consider the builders clean alongside their office fitout programme. Cleaners and contractors looking for work can review current opportunities on the WA tradie job leads board, where commercial contracts appear regularly and are posted year round. Other building services are listed on our WA services hub.

Insurance, Liability and Australian Consumer Law

Public liability cover is the baseline and the amount matters more in cleaning than clients often assume. Cleaners work unsupervised in occupied premises, handle chemicals near finishes and equipment, work at height, and create wet floors that generate slip claims. Twenty million dollars is a common commercial requirement. Ask for a current certificate of currency rather than an assurance, check the expiry date, and confirm the policy actually covers the activities in your scope including any height work.

Workers compensation is a separate and essential verification wherever the contractor employs staff. Where a contractor uses subcontractors rather than employees, ask how those workers are covered, because an injured worker with no cover can become the site occupier's problem. This is one of the practical reasons the subcontracting chains common at the lower end of the market create risk for clients as well as for workers. It is worth resolving before the contract starts. Resolving it after a claim is considerably harder.

Damage to finishes is the most common cleaning claim and it is usually chemical rather than physical. Etched stone, stripped sealers, discoloured grout, damaged timber and marked fabric all result from product selection rather than accident. This is why asking about chemical selection is worth doing before rather than after. Where damage occurs, it sits with the contractor's public liability cover, and a contractor without adequate cover leaves the building owner carrying it.

Australian Consumer Law applies to cleaning services, with guarantees around due care and skill and fitness for purpose that cannot be excluded by contract terms. Consumer Protection WA publishes guidance for WA businesses, and the ACCC covers the national framework. Food premises obligations sit with the Department of Health WA and local government. Businesses working through their broader regulatory obligations can start at ABLIS, and general service information is available through the WA Government. Reading either before a problem arises is far more useful than after.
