Why Queensland Requires Plumbing Licences
Plumbing is a regulated trade in Queensland because incorrect plumbing work can contaminate drinking water, cause sewage backups, create gas leaks, and lead to property damage. The Queensland Building and Construction Commission (QBCC) oversees licensing to ensure that anyone performing plumbing work has completed the required training, holds appropriate qualifications, and maintains insurance. Queensland law makes it an offence to perform plumbing work without a licence, and homeowners who knowingly engage unlicensed plumbers for work valued over $3,300 can also face penalties. The licensing system protects consumers through the Home Warranty Scheme, which covers defective work for up to 6.5 years.

QBCC Plumbing Licence Classes Explained
The QBCC issues several classes of plumbing licences. An unrestricted plumbing licence (also called a full plumbing licence) allows the holder to perform all types of plumbing work including water supply, sanitary plumbing, drainage, gas fitting, and roofing (stormwater). Restricted licences limit the holder to specific types of plumbing work — for example, a plumber may hold a restricted licence that only covers drainage work, or only water supply. There is also a separate licence class for draining, which covers stormwater and sewer drainage only. For emergency work on your home, you generally want a plumber with an unrestricted licence, as emergency situations can involve multiple plumbing systems.
- •Unrestricted licence: all plumbing work (water, sewer, gas, drainage)
- •Restricted licence: limited to specific work types
- •Draining licence: stormwater and sewer drainage only
- •Gas fitting: may require a separate endorsement
- •For emergencies, an unrestricted licence is ideal
How to Verify a Plumber's QBCC Licence
Checking a plumber's licence takes less than 2 minutes. Visit qbcc.qld.gov.au and click on 'Check a licence' in the navigation menu. You can search by the plumber's name, their business name, or their QBCC licence number. The search results will display the licence status (current, suspended, or cancelled), the licence class and any conditions or restrictions, the licence expiry date, and any disciplinary actions or compliance notices. A plumber with a current, unrestricted licence and no disciplinary actions is what you are looking for. If the plumber's licence shows as suspended or cancelled, do not engage them — their licence has been revoked for a reason.
- •Go to qbcc.qld.gov.au and click 'Check a licence'
- •Search by name, business name, or licence number
- •Check: status (current), class (unrestricted preferred), expiry date
- •Look for any disciplinary actions or compliance notices
- •Suspended or cancelled licence = do not hire
- •A legitimate plumber will provide their licence number willingly
Your Rights When Hiring a Licensed Plumber
When you hire a QBCC licensed plumber, you are protected by Queensland consumer law and the QBCC Home Warranty Scheme. You have the right to a written quote before work begins (for non-emergency work, or after initial assessment for emergencies), an itemised invoice showing labour, materials, and any callout fees, a compliance certificate for regulated plumbing work, warranty coverage for defective work for up to 6.5 years, and the right to lodge a complaint with QBCC if the work is substandard. If a dispute arises, the QBCC can investigate, order rectification work, and take disciplinary action against the plumber's licence. This protection only exists when you use a licensed plumber — another critical reason to always verify.
