The short answer
For existing floors, no Australian law prescribes slip testing at a fixed interval. What the law imposes instead is an outcome: under work health and safety legislation, whoever controls a workplace or public premises must manage slip and fall risk so far as is reasonably practicable. Objective testing to AS 4663:2013 is the accepted way to know whether that duty is being met, and the accepted way to prove it afterwards. For new construction, the position is firmer: the National Construction Code mandates minimum slip resistance classifications for elements such as stairs, ramps and their landings.
Where the duty comes from
Three legal threads matter here:
- Work health and safety law. Every state and territory places a duty on those who run or control a workplace to provide safe premises, including safe floor surfaces. In most jurisdictions that is the harmonised WHS Act, which binds the person conducting a business or undertaking and gives officers a personal due diligence duty to verify that risks are being managed; Victoria imposes equivalent duties on employers and those with management or control of a workplace under its Occupational Health and Safety Act. Under either regime, the duty cannot be discharged by assuming the floor is fine.
- The National Construction Code. For new building work, the NCC calls up minimum classifications from AS 4586:2013 for stair treads, nosings, ramps and landings. Certifiers routinely require test evidence before sign-off. Our guide to slip resistance for stairs and ramps covers the specifics.
- Civil liability. When someone is injured in a slip and fall, occupiers are judged on whether they took reasonable care. Courts consistently treat objective evidence about the floor's condition, or the absence of it, as central to that question.
Situations where testing is effectively required
Beyond the black-letter law, a set of practical obligations makes testing hard to avoid:
- New floors and certifications. Building certifiers, and increasingly principal contractors at handover, want documented classifications for the surfaces the NCC covers.
- After an incident. Once someone has slipped, insurers, lawyers and in serious cases regulators will ask what the slip resistance of the surface was. Testing promptly, before conditions change, protects you either way. See our guide on what to do after a slip incident.
- Insurance and leases. Public liability insurers increasingly ask about floor safety programs at renewal, and commercial leases often oblige tenants or landlords to maintain safe premises, which is difficult to evidence without data.
- Regulated sectors. Aged care, healthcare and education operate under safety and quality frameworks where falls are a headline risk. Documented floor testing is a natural part of demonstrating compliance. Our article on slip resistance in aged care goes deeper.
- Tenders and contracts. Facility management contracts and cleaning tenders increasingly specify periodic slip testing as a deliverable.
What happens if you never test
Nothing, until something goes wrong. The problem arrives with the first serious incident. A claimant's lawyer will ask for your slip resistance records, and if there are none, the argument writes itself: the occupier had no idea how the floor performed and took no steps to find out. Conversely, a documented history of testing to AS 4663:2013, with failed surfaces rectified and retested, is about the strongest practical demonstration that slip risk was being managed. The cost of a testing program is trivial next to the cost of defending a claim without one.
What a reasonable program looks like
You do not need to test every square metre of every floor. A defensible program tests the locations where risk concentrates, entries, wet areas, kitchens, ramps and busy circulation routes, at a sensible interval, and acts on the results. For most commercial sites that means an annual round, with high-risk areas checked more often. Our guide on how often slip testing should be done sets out a practical calendar.
Get ahead of the question
If you are not sure where your site stands, a single well-scoped testing round answers the question and starts the paper trail. We test commercial sites across Melbourne, Sydney and Brisbane, and every report interprets your results against HB 198:2014 guidance in plain English.
