Tasmanian plumbing licences are issued through Consumer, Building and Occupational Services (CBOS) under the Occupational Licensing Act 2005. The Occupational Licensing (Plumbing Work) Regulations 2021 provide a plumbing contractor licence for the business, and practitioner licences for the people doing the work, including certifier, provisional and restricted ones. Section 21 of the Act says a person mustn't carry on business as a contractor without a contractor's licence for that work, and section 38 says nobody may represent that they're prepared to contract for prescribed work unless the intended contractor holds the relevant licence. The old section that required licence numbers in advertisements was repealed from 1 January 2017, as our page for Hobart tradies explains, but a visible number is still the quickest proof that you're licensed. CBOS can tell you what applies to your licence.
Plumbing work in Tasmania is sorted by risk under the Director's Determination on categories of plumbing work, and your local council acts as the plumbing permit authority. Glenorchy City Council sums it up clearly: Category 1 work can be done by the owner; Category 2A needs a licensed plumber but no approval; Category 2B needs a licensed plumber and a notice to council once it's finished; Category 3 can't start until council has received a Notice of Work and a design and issued a Certificate of Likely Compliance; and Category 4 also needs a plumbing permit, with staged inspections for both. The City of Hobart's entry on ABLIS, the government's business licence finder, puts repairs and changing fixtures in the low-risk group, and onsite wastewater systems and backflow devices among permit work. In the City of Hobart, building and plumbing applications can only be lodged through PlanBuild Tasmania, inspections are booked online with at least 24 hours' notice and a licensed plumber on site, and a final inspection needs the Standard of Work Certificate (Form 71B) and, where it applies, an as-constructed drainage plan.
TasWater supplies drinking water and collects sewage across the state. It manages the mains, and property owners are responsible for everything on their side of the connection point, which may be the meter or the first valve near the boundary. For a blockage, TasWater's advice is to ring your plumber first; a plumber isn't authorised to work on TasWater's infrastructure without permission, and it won't pay for repairs it didn't approve. Owners must have a working overflow relief gully and must never cover it, leaks between the connection point and the house are the owner's to fix, and a concealed leak may earn a one-off rebate of up to 50% of the usage above the average bill, once a licensed plumber's written evidence of the repair is supplied. Work within 2 metres of TasWater's pipes or inside one of its easements may need its Certificate for Certifiable Work.
TasWater requires a backflow containment device, matched to the property's hazard rating, at the boundary of every property connected to its supply. Apart from water meters, the owner owns the device and pays for installing, maintaining and testing it each year. Glenorchy keeps a register of devices, sends owners a yearly reminder and invoice, expects each device to be tested every 12 months by a licensed plumber, and needs a copy of the passing test report. Where there's no sewer, the City of Hobart needs a plumbing permit, backed by a site and soil evaluation and a system design from a qualified person, before an onsite wastewater system goes in, and the owner must use a certified contractor for maintenance and keep ten years of maintenance records. Not every street fronts the Tas Gas Networks pipeline, and its pipeline locator lets an owner check their address, so if you also hold a gas-fitting licence, say whether you work on mains gas, bottled gas or both.
