Plumber

 

🇦🇺 Introduction

A plumber licence is an official authorisation issued by a state or territory regulatory authority that permits an individual or business to legally carry out plumbing work. Plumbing work typically involves the installation, repair, and maintenance of systems that supply:

•         Water (potable and non-potable)

•         Sanitation (drains, sewerage, and stormwater)

•         Gas (natural gas or LPG) – if holding a gasfitting endorsement

•         Heating, cooling, and fire protection systems in certain contexts

The licence ensures that the plumber:

•         Has the necessary skills, qualifications, and experience to perform plumbing work safely and effectively.

•         Complies with workplace health and safety (WHS) regulations.

•         Adheres to building codes, plumbing codes, and Australian Standards (e.g., AS/NZS 3500 series).

•         Can legally contract plumbing work, including work above the residential project threshold.
