Choosing a commercial cleaning company isn't really a cleaning decision — it's a risk decision. The cleaner you choose has access to your premises, sees your confidential information, represents your brand to anyone who walks past their cart, and (if you're regulated) is part of your compliance chain. Get this wrong and you don't just have a dirty office; you have an operational and reputational exposure.
This guide gives you the 12 questions that filter most weak operators within the first conversation. We've grouped them into four buckets: compliance (the entry ticket), workforce (where things actually break or work), technology (the verification layer), and commercial (how you price and govern the contract).
If you're running a tender, use this as your evaluation matrix. If you're doing a vendor review, use it as a discussion guide with your current operator. If you're new to facility management, this is the framework most experienced FMs already have in their head.
Compliance · the four documents every operator must produce
If an operator can't produce these four documents on the spot, your evaluation ends here.
- 01Current ISO 9001:2015 certificate (Quality Management) from Certifi International or equivalent — version must be 2015, not 2008
- 02Current AS/NZS ISO 45001:2018 certificate (Health & Safety Management) — required for any work involving heights, hydro, industrial sites
- 03Current AS/NZS ISO 14001:2015 certificate (Environmental Management) — required for ESG-aware buyers and most government tenders
- 04Cm3 contractor prequalification — verifiable in the Cm3 portal with the operator's profile ID
Workforce · the model is what matters
The single biggest predictor of cleaning quality is the workforce model — direct-employee, labour-hire, or subcontracted. Direct-employee operators invest in training, retention, supervision, and compliance because they bear all the cost of churn. Subcontracted operators externalise that cost to the subcontractor, which usually externalises it again to the individual worker. The quality difference shows up by the second visit.
- ·Direct-employee · cleaners on the operator's payroll with super, leave, workers' comp, and Cert III training
- ·Labour-hire · cleaners on a third-party labour-hire company's payroll, dispatched to the operator's sites
- ·Subcontracted · the operator pays a smaller cleaning company who employs the cleaners (or further subcontracts)
- ·Mixed · the operator uses different models in different states or regions — this is common and worth asking about
"Ask: 'Are the cleaners on my site W-2 employees of your company, or are they paid through a labour-hire or subcontractor arrangement?' If they can't answer cleanly, you have your answer."
Training · Cert III is the floor, not the ceiling
Every commercial cleaner working on a multi-site contract should hold Certificate III in Cleaning Operations. This is the Australian baseline qualification — it covers chemistry, equipment, WHS, customer-presence protocols, and basic infection control. Operators who skip this either save money on training or hire from a pool that's already qualified.
Above Cert III: First Aid (senior site supervisors), Working at Heights (high-access work), Test and Tag (electrical tool currency), and sector-specific specialty (NSQHS Standard 3 for healthcare, NQF Quality Area 3 for childcare, AS 4674 for food-grade industrial). Ask which of these your assigned crew holds and request the currency dates.
Technology · proof of work, not just trust
The market has moved from "we cleaned it, trust us" to "we cleaned it, here's the photo." Modern operators run a client-facing platform that logs every visit with geofenced sign-in (proves the cleaner was actually on site), photo-ID verification (proves it was the right cleaner), and photo evidence of completed tasks (proves the work was done). Some operators add ATP testing integration for healthcare-adjacent contracts.
Ask: "Walk me through your client portal — I want to see a typical visit log from one of your current contracts." If the operator can't show you, the platform is either non-existent or unused.
Audit cycle · monthly to annual
Mature operators run a three-tier internal audit cycle plus an external audit annually. Tier 1 is the site supervisor inspecting their own crew (typically weekly). Tier 2 is the area manager inspecting across sites (typically monthly). Tier 3 is the corporate compliance manager auditing the audit programme (typically quarterly). Annual audit is the external auditing body (Certifi International for triple-ISO operators) examining the full management system.
Ask: "How often is my site audited and at what tier? Can I see a sample audit report from another site?" Real operators audit your site at least monthly at tier-2 level. Operators who audit only when there's a complaint don't have a programme — they have a complaint-response process.
Quote structure · line-item vs. lump-sum
Lump-sum quoting is the industry's biggest source of dispute. The operator quotes "$3,200/month for daily cleaning," you sign, and three months later the scope creeps or the operator argues that ATP testing was "an add-on." Line-item quoting solves this. Every component (labour by frequency, supplies, equipment, overhead, margin) is itemised. If you ask to drop a service line, the impact on your invoice is visible same day.
"If your quote doesn't show a margin line, the margin is hidden inside the labour rate. That's not an accusation — it's arithmetic."
Transparency · the operator who hides nothing wins long-term
- ·Will they publish their ISO certificate numbers and the audit body name?
- ·Will they publish their Cm3 verification number for direct lookup?
- ·Will they publish their Labour Hire Licence number for public-register lookup?
- ·Will they put the margin line on the quote, not hidden in inflated labour rates?
- ·Will they let you walk through their client portal during the sales process?
- ·Will they connect you with current clients in your sector for reference calls?
References · the questions that matter on the reference call
When you call a reference, don't ask "are they good?" — everyone is good in the abstract. Ask operational questions that probe failure modes: "What happened the last time they failed to show up for a scheduled visit?" "How long did it take them to respond to a 24/7 emergency callout?" "Have you ever had a complaint that required escalation to their area manager?" "What did the escalation look like?"
Pricing · what "competitive" actually means
For mid-size Australian commercial offices, daily cleaning sits in the $40–$60 per visit range for entry-level operators and $60–$90 per visit for triple-ISO operators with direct-employee workforces. The premium covers training currency, audit infrastructure, technology platform, compliance documentation, and helpdesk capacity.
Quotes far below this range usually come from operators running undertrained or under-paid workforces, or who haven't accounted for required compliance overhead. Quotes far above are usually multinational FM-integrators adding a management layer between you and the actual operator.
The 12 questions above (4 compliance + 4 workforce/training + 2 technology/audit + 2 commercial) take about 45 minutes to work through in a first meeting. They filter out roughly 80% of the operators in the Australian market who claim to be commercial-cleaning-grade but actually aren't.
