Building Commission NSW has clarified supervision requirements for apprentice plumbers, tradesperson certificate holders and unlicensed workers, outlining a new approach aimed at lifting standards while addressing workforce shortages.

The updated supervision framework is detailed in a Statement of Regulatory Intent (SRI) and will take effect from 1 February 2026, following consultation with industry groups. The SRI responds to concerns that inadequate supervision by licensed plumbers has contributed to substandard plumbing work across the state.

Under the revised approach, supervision requirements will be enforced through two clearly defined categories: Immediate supervision and general supervision.

Immediate supervision will apply to first to third-year apprentices, as well as unlicensed and unqualified workers. It requires a licensed plumber to be physically present on site and available to provide direct guidance and feedback.

General supervision will apply to fourth-year apprentices and tradesperson certificate holders. While a licensed supervisor does not need to be physically present under this category, they must provide ongoing guidance and monitoring and remain accessible by phone or virtual means.

Building Commission NSW says the clarified rules strike a practical balance between improving oversight and recognising the current shortage of licensed plumbing supervisors.

The changes follow a compliance blitz earlier this year, which targeted unsupervised plumbing work after inspectors identified widespread non-compliance across multiple sites. During one inspection in Port Macquarie, five apprentices were found working without supervision, resulting in a $1,500 fine for the licensed plumber responsible.

Overall, the blitz resulted in six penalty infringement notices and six education letters being issued to employers for supervision breaches.

NSW Building Commissioner James Sherrard says the updated rules would remove long-standing confusion within the industry: “Over the years, there has been confusion over the existing supervision rules for apprentices, especially when it comes to terms like ‘immediate’ and ‘general’ supervision.”

“These rules clarify what plumbing supervision requirements are and will help ensure apprentices receive appropriate direction, but also empower them to operate independently when ready.”

The SRI will remain in effect until 31 January 2028, allowing time for industry participants to obtain required certificates under the Home Building Act and for broader legislative reforms to be considered if needed.
