This is a conversation I have regularly. A business owner calls us and somewhere in the first five minutes they say something like “we have been thinking about just hiring someone ourselves” or “we had someone in-house but it did not work out” or “we are trying to figure out what makes more sense financially.”

It is a fair question. On the surface, hiring your own cleaner looks straightforward. You find someone, pay them a few hours a week, and the office gets cleaned. Simple. Cheaper than a cleaning company. No middleman taking a margin.

Except it almost never works out that way. I have been running Nexus Kleen since 2015 and we clean over 400 Perth offices every week. A significant number of those clients came to us after trying the in-house route first. Some had a cleaner who left and they did not want the hassle of replacing them. Some had a cleaner whose standard was not good enough but nobody felt comfortable managing them. And some never tried in-house at all but sat down and did the maths properly before making a decision.

Here is what I have learned from watching both approaches play out across hundreds of Perth businesses over the past decade.

The Real Cost of an In-House Cleaner

Most business owners compare the hourly rate of an in-house cleaner to the hourly rate of a cleaning company and think the decision is obvious. A cleaner from Seek or Gumtree might accept $30 an hour. A professional cleaning company charges $55 or more. Why would you pay nearly double?

Because $30 an hour is not what an in-house cleaner actually costs you. Not even close.

Here is what you are really paying when you hire someone directly:

The wage itself. Let us say $30 per hour for 10 hours a week. That is $300 per week or $15,600 per year.

Superannuation. You are legally required to pay 11.5% super on top of their wage. That is another $1,794 per year.

Workers compensation insurance. Cleaning is classified as a higher-risk occupation. Workers comp premiums for cleaning staff in WA typically run 3-5% of wages. Call it $624 per year at the low end.

Sick leave and annual leave. If they are a part-time employee (not casual), they accumulate paid leave entitlements. Even at 10 hours a week, that adds up to roughly 2 weeks of paid leave per year where you are paying them but nobody is cleaning your office.

Cleaning products and equipment. Vacuum cleaner, mop and bucket, microfibre cloths, bathroom cleaner, glass cleaner, floor cleaner, disinfectant, bin liners, toilet paper, hand soap, paper towels. You are buying all of it. And replacing the vacuum when it breaks. And the mop heads. And restocking the chemicals every month. Budget $2,000 to $3,000 per year minimum for a single office.

Payroll administration. Someone in your business has to process their pay, manage their super, handle their tax, track their leave, and deal with any HR issues. If you use an accountant or payroll service, that is an additional cost. If your office manager does it, that is their time being spent on payroll instead of their actual job.

Add it all up and your $30 per hour cleaner is costing you closer to $22,000 to $25,000 per year before you factor in the hidden costs that nobody thinks about until they hit.

The Hidden Costs Nobody Tells You About

The dollar costs above are predictable. You can budget for them. The costs that actually hurt are the ones you do not see coming.

When the cleaner is sick, nobody cleans. This is the single most common complaint I hear from businesses that tried in-house. Your cleaner calls in sick on Monday. The office does not get cleaned. They are still sick on Wednesday. The office has not been cleaned in three days. By Friday, the bathroom is unpleasant, the kitchen smells, and the bins are overflowing. Who covers? Usually the office manager, who has their own job to do. Or nobody, and clients walk into a visibly dirty office.

With a cleaning company, if one cleaner is sick, the company sends a replacement. Your office gets cleaned regardless. That is not a perk. That is the entire point.

When the cleaner goes on holiday, nobody cleans. Same problem, except planned. Two weeks of annual leave means two weeks of either no cleaning or your office manager scrambling to find someone to fill in. Most businesses end up asking their own staff to pitch in, which goes down about as well as you would expect.

Nobody manages the cleaner. This is the one that slowly destroys the arrangement. When you hire an in-house cleaner, who checks their work? Who tells them when the standard has dropped? Who inspects the bathrooms, the kitchen, the floors? In most businesses, the answer is nobody. The office manager might notice when something is obviously wrong, but they are not doing scheduled quality inspections. They are not walking through with a checklist. They are not providing feedback in any structured way.

So the standard drifts. It starts fine. After a few months, the cleaner settles into a routine that covers the minimum. The corners get missed. The kitchen gets a surface wipe instead of a proper clean. The bathroom mirrors have spots. Nobody says anything because it is awkward to manage someone on something as personal as their cleaning standard. And before you know it, you are paying for a cleaner who is doing 70% of the job while everyone pretends it is fine.

No accountability, no documentation. An in-house cleaner does not provide photo documentation of every visit. They do not log their time with GPS verification. They do not have a supervisor who audits their work. You are trusting that the job was done properly with no way to verify it other than walking through yourself. And most business owners do not have the time or the inclination to audit their cleaner’s work.

Insurance gaps. If your in-house cleaner damages something in your office, slips on a wet floor, or injures themselves while cleaning, your business insurance may or may not cover it depending on your policy. Most small business insurance policies do not include employer liability for cleaning staff because it is not the primary business activity. A professional cleaning company carries its own $20 million public liability insurance on every job. If something goes wrong, their insurance handles it, not yours.

What You Actually Get When You Outsource

When you engage a professional office cleaning company — and I am not just talking about Nexus Kleen, I mean any company that operates properly — here is what the arrangement looks like:

The cleaning company handles recruitment, training, and HR. You do not interview cleaners. You do not train them. You do not manage their leave, their super, their workers comp, or their sick days. You do not have difficult conversations about performance. The cleaning company does all of this. Your involvement is limited to saying “we need cleaning” and then receiving a clean office.

Sick leave and holidays are covered automatically. If your assigned cleaner is sick, the company sends a replacement. If they are on holiday, the company sends a replacement. Your office gets cleaned every scheduled visit regardless of what is happening in the cleaner’s personal life. You do not even know about it because the company manages it behind the scenes.

Quality is managed by someone whose job it is. A properly run cleaning company has supervisors, quality inspection schedules, photo documentation systems, and feedback processes. Someone whose actual job is ensuring cleaning quality is checking the work regularly. That person is not your office manager doing it as a favour on top of their real responsibilities.

Products, equipment, and consumables are included. The cleaning company brings everything. Vacuum, mop, cloths, chemicals, bin liners. When the vacuum breaks, they replace it. When the chemicals run out, they restock. When a new product becomes available that works better, they switch to it. You do not have a cleaning supply cupboard in your office taking up space and you do not have “buy more toilet cleaner” on anyone’s to-do list.

Insurance is sorted. The cleaning company carries public liability insurance that covers every visit. If a cleaner damages something, the company’s insurance covers it. If a cleaner is injured in your office, their workers comp covers it. Your business insurance is not involved.

You focus on your business. This is the point that matters most. You started your business to do whatever it is you do. Legal advice, financial planning, medical practice, engineering, recruitment, whatever. You did not start your business to manage a cleaner. Every hour your office manager spends dealing with cleaning supplies, interviewing replacements, checking bathrooms, or covering for a sick cleaner is an hour they are not spending on their actual job. Outsourcing gives that time back.

The Cost Comparison That Actually Matters

Here is a realistic comparison for a typical Perth office of 100 to 200 square metres cleaned three times per week.

In-house cleaner:
Wages (10 hours per week at $30/hr): $15,600 per year
Superannuation (11.5%): $1,794
Workers compensation: $624
Cleaning products and equipment: $2,500
Payroll admin time (your office manager): $1,500 value
Sick leave and holiday coverage: unquantifiable but real
Quality management time: unquantifiable but real
Total visible cost: approximately $22,000 per year
Total real cost including hidden items: $25,000 to $28,000 per year

Outsourced cleaning company:
Fixed price per clean, three times per week: $1,500 to $1,800 per month
Total annual cost: $18,000 to $21,600 per year

The outsourced option costs the same or less than in-house and you get sick leave coverage, holiday coverage, quality management, insurance, equipment, products, and zero HR burden included in that price. There is no scenario where in-house is genuinely cheaper once you account for everything.

When In-House Cleaning Can Work

I am not going to pretend that in-house cleaning has zero advantages. There are genuine reasons some businesses consider it and I think it is important to be honest about them.

Immediate availability. If you need something cleaned right now, an in-house cleaner who is already on site can deal with it immediately. A spill in the boardroom five minutes before a client meeting, a bathroom issue during the day, a kitchen mess after a team lunch. Having someone physically present during business hours to handle these things is genuinely useful.

Familiarity with staff. An in-house cleaner becomes part of the team over time. They know everyone by name, they understand the culture, and staff feel comfortable asking them for things directly. There is a personal connection that an after-hours cleaner who never meets your team cannot replicate.

Daytime cleaning. Some businesses prefer cleaning during the day rather than after hours. An in-house cleaner can do this because they are on site during operating hours. Most outsourced cleaning companies work after hours, although we do offer daytime cleaning for clients who need it.

However, here is where each of those advantages falls apart in practice.

The immediate availability advantage disappears the moment that cleaner calls in sick, goes on holiday, or leaves the job entirely. The familiarity advantage can actually work against you — when the cleaner is too close to the team, it becomes almost impossible to give them honest feedback. Nobody wants to tell someone they see every day that the bathrooms are not clean enough. And daytime cleaning creates disruption that after-hours cleaning eliminates completely.

The advantages of in-house are real but they come with conditions that most businesses only discover after committing to the arrangement. The disadvantages are permanent and structural.

The Bottom Line

Outsourcing your office cleaning is not about finding the cheapest option. It is about removing cleaning from your list of things to manage so you can focus on running your business. The cost is comparable or lower than in-house. The quality is higher because someone whose actual job is managing cleaning quality is checking the work. The reliability is higher because sick leave and holidays are covered automatically. And the administrative burden drops to zero.

If you are currently managing an in-house cleaner and spending time on recruitment, products, supervision, and covering sick days, that is time and energy your business is spending on something that is not your core competency. Every hour your team spends on cleaning management is an hour they are not spending on the work that actually generates revenue.
