Hot Water Systems Licensing & Rules in New South Wales
Important regulations and resources to help you hire with confidence in New South Wales.
Plumbing Contractor Licence
A plumbing contractor licence issued by NSW Fair Trading is required to contract, subcontract or advertise for plumbing, water‑plumbing, draining or gasfitting work. Installing or repairing a hot water system is considered specialist plumbing work.
Licensed Tradesperson Requirement
Homeowners using their own installer must engage a licensed tradesperson. A licensed plumber and/or electrician supplied by the installer will install the new hot water system, demonstrate its operation and safely dispose of the old system.
Compliance Documentation and Complaints
Following installation, the installer must provide documentation (such as a Post Implementation Declaration) and may take photos to show that the installation meets requirements. Complaints about unlicensed work should be referred to NSW Fair Trading or the Building Commission NSW.
Standards Compliance
Hot water installations must comply with AS/NZS 3500 plumbing standards and the Building Code of Australia to ensure safety and performance.
