How to Choose a Commercial Cleaning Company in New South Wales
Picking the wrong commercial cleaner costs more than the cleaning contract. Unreliable staff, missed visits, damaged surfaces and wasted time re-briefing new teams add up quickly. This guide covers exactly what to check, what to ask, and what to avoid — so you get a cleaning company you can trust long-term.
8 Steps to Choosing the Right Commercial Cleaning Company in NSW
Define what you actually need cleaned
Before contacting any cleaning company, document: the size of your facility (approximate square metres), which areas need cleaning (offices, bathrooms, kitchen, warehouse floor, car park, external areas), how often you need it done (daily, 3× per week, weekly), any specialist requirements (medical-grade, food-safe, high-reach) and whether you need after-hours access. Vague briefs produce vague quotes — and you will not be able to compare companies accurately.
Verify insurance before anything else
This is non-negotiable. Any commercial cleaning company operating in NSW must hold: (1) Public Liability Insurance — minimum $10 million, ideally $20 million for commercial premises; (2) Workers Compensation Insurance covering all staff working in your facility; (3) Professional Indemnity Insurance if they are providing specialist services. Ask for certificates of currency — not a verbal assurance. Any reputable company will provide these immediately. If they stall or cannot produce them, move on.
Confirm staff are police-checked and directly employed
Ask directly: "Are all staff who will work on our site police-checked?" and "Are they directly employed by your company or sub-contracted?" Sub-contracting is common in the cleaning industry and is not automatically a problem — but you need to know whether the company's vetting standards apply to sub-contractors or only to their own staff. For sensitive environments (medical, childcare, aged care, corporate offices with confidential information), only use companies whose staff are directly employed and comprehensively vetted.
Check real reviews — not testimonials on their own website
Look for reviews on: Google Business Profile (aim for 4.5+ stars, 50+ reviews), ProductReview.com.au, Oneflare, hipages and ServiceSeeking. Pay attention to: how the company responds to negative reviews (professional and solution-focused is a good sign), reviews that mention reliability and consistency (not just the first clean), and the recency of reviews. A company with 200 reviews from 2021 and nothing recent may have changed significantly. Testimonials on the company's own website are not independently verified.
Request a site visit — not just a quote over the phone
A commercial cleaning quote given without a site inspection is usually inaccurate. A thorough cleaner will want to walk your facility, understand access requirements, assess floor types and surface materials, identify any specialist areas and meet the person responsible for managing the relationship. A quote based on a site visit is a commitment; a phone quote is an estimate that may change significantly once work begins. If a company refuses to do a site inspection for a commercial premises, that is a red flag.
Read the contract carefully — especially these clauses
Before signing, check: (1) Lock-in period — anything over 30 days notice to cancel warrants scrutiny; (2) Price increase clauses — understand when and how prices can change; (3) Service specification — is what will be cleaned written into the contract in detail, or is it vague? (4) What happens if a clean is missed — is there a credit or make-good process? (5) Who is the named contact for issues? (6) Sub-contracting disclosure. See our full guide on what to look for in a commercial cleaning contract.
Start with a trial clean before committing
Ask for a paid trial clean or a first-visit assessment before signing a long-term agreement. This gives you: a chance to evaluate the actual quality of work versus the sales pitch, an opportunity to assess the team's punctuality and professionalism, and a baseline against which to measure consistency. Any company confident in their work will accept a trial. If they insist on a contract before you have experienced the service, that is a significant warning sign.
Understand exactly who will clean your facility
Ask: "Will I have the same team every visit?" Consistency matters more than most business owners realise. A cleaner who knows your facility — your security codes, your surface materials, your specific preferences, your layout — will clean it better and faster than someone new each time. Ask for the name and direct contact of the team leader who will be responsible for your account. Impersonal or difficult-to-reach account management is one of the most common complaints about commercial cleaning companies.
