What licence does a tiling business need in Australia?

Does a tiling business need a licence to operate in Australia?

Yes, in most states a tiling business needs a licence, registration or certificate before it can legally take on residential tiling and waterproofing work, though the exact requirement and the trigger for needing one differs from state to state. Whether a tiler needs an individual contractor licence, a company licence, or can rely on a builder's registration depends on where the work is, who is engaging the tiler, and the value of the job.

This matters for day to day quoting. A bathroom retile with waterproofing to a shower recess, or a full kitchen and wet area renovation, can sit above the point where a licence is required, even where a smaller splashback or repair job does not. A tiler who only ever thinks about the day rate or the square metre rate can miss that the job itself has crossed into licensed territory.

Does the licence rule change between states?

Yes, each state and territory runs its own licensing system for tilers, with its own regulator, its own licence classes and its own threshold for when a licence is triggered. A tiler working mainly in one state can get used to one set of rules, then find a job across the border runs on a different system entirely.

In New South Wales, NSW Fair Trading says a contractor licence is needed for residential building or trade work, including roof tiling and wall and floor tiling, once the work is valued above a threshold set out on the page, issued under the Home Building Act 1989 (NSW). Licence types include an individual contractor licence or endorsed contractor licence, a company or partnership contractor licence, or a qualified supervisor certificate, as set out on the NSW roof tiling licences page and the NSW wall and floor tiling work page.

In Victoria, the Victorian Building Authority runs a domestic builder registration class limited to wall and floor tiling, covering affixing tiles for functional or decorative use and waterproofing the tiled area, and a separate class limited to roof tiling, as described on its domestic building work page.

In Queensland, the Queensland Building and Construction Commission issues a roof tiling licence and a separate wall and floor tiling licence, each reached through an apprenticeship or a relevant Certificate III, set out in its technical qualifications for licensing document.

In Western Australia, a tiler employed by a registered builder does not need their own licence, but a tiler who contracts directly with clients above a set threshold needs to register as a building contractor, according to Build a Life in WA.

In South Australia, Consumer and Business Services requires individuals and businesses providing building services to hold a building work contractor's licence, with supervision requirements, under the Building Work Contractors Act 1995 (SA).

Tasmania, the Northern Territory and the ACT are not covered by the sources used here, so a tiler working in those jurisdictions should check directly with the local building regulator rather than assume any of the above applies.

Does the licence depend on roof tiling, wall and floor tiling, or both?

Yes, most states separate roof tiling from wall and floor tiling as different licence classes, each with its own qualification pathway, so a tiler doing both kinds of work can need two licences, not one. A roof tiler laying terracotta or concrete roof tiles sits under a different licence and a different Certificate III pathway to a tiler doing bathroom, kitchen and wet area work.

This split shows up clearly in Queensland and New South Wales, where the qualification named for roof tiling (a Certificate III in Roof Tiling or equivalent) is separate from the qualification named for wall and floor tiling (a Certificate III in Wall and Floor Tiling). Victoria's domestic builder classes follow the same split, with the wall and floor class covering waterproofing of the tiled surface itself.

What does keeping a tiling licence and its paperwork up to date actually cost you in time?

The real cost is not the licence fee, it is the ongoing paperwork: tracking renewal dates, keeping qualification and supervisor certificates current, checking a subcontractor's own licence before putting them on a builder's job, and keeping waterproofing records for warranty claims. Most tilers carry this in memory or a folder on the ute dash, which works until a renewal is missed or a builder asks for proof mid-job.

The number that tells the truth here is not a feeling about “being on top of it”, it is the owner's own job data: which jobs crossed the value threshold that triggers a licence requirement, which subcontractors are booked on which jobs, and when each qualification, certificate or insurance document is due to lapse. Pulled from memory at the end of a busy renovation season, this is usually out of date. Pulled from the business's own records, it is accurate the day it is checked.

This is where AI agents change the non-billable side of running a tiling business. An AI agent is software that does a job the way the owner would, with their prices, wording and rules, so it can watch job values against licence thresholds, flag an expiring supervisor certificate, or chase a subcontractor for their current licence before they turn up on site, without the owner having to remember to do it. A data first approach starts from the tiling business's own job and compliance data rather than a general checklist, so the paperwork that protects the licence and the waterproofing warranty gets done from what is actually happening on the tools, not from memory.

How does Data First Coaching approach this?

Data First Coaching, built by Greg Allan, looks first at the tiling business's own job and compliance records rather than a general licence checklist, because a licence problem is usually a symptom of a paperwork system that has fallen behind the work, not a one-off oversight. Through the Trade Business Intelligence, Greg starts from the owner's own data, whether that is job values against licence thresholds, subcontractor documents, or warranty records on waterproofing, to find where the gap actually starts. The how, including the systems members build to carry this load automatically, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member, for owners who are open minded, innovative and willing to share what they learn.
