Clearer supervision requirements for apprentice plumbers, plumbing certificate holders, and unlicensed or unqualified workers have been set out in a new Statement of Regulatory Intent (SRI).
This is following collaboration between Building Commission NSW and industry stakeholders to lift standards across the sector.
The updated supervision framework, which takes effect from 1 February 2026, responds to concerns that some licensed plumbers were failing to adequately supervise workers, resulting in substandard plumbing work.
“We recognise the important role plumbers play in the state’s construction sector, as one of the most in demand, experienced and highly trained occupations operating on building sites across the state,” NSW Building Commission James Sherrard said.
“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.”
Two-tier system
Under the new arrangements, Building Commission NSW has clarified the existing two-tier supervision model, formalising the requirements for Immediate Supervision and General Supervision.
Immediate Supervision will apply to first-, second- and third-year apprentices, as well as unlicensed and unqualified workers.
This level of supervision requires a licensed plumber to be physically present and available to provide direct guidance, oversight and feedback on work being carried out.
General Supervision will apply to fourth-year apprentices and tradesperson certificate holders. Under this model, licensed plumbers are required to provide intermittent guidance, monitoring and supervision.
“These new rules clarify what plumbing supervision requirements are and will help ensure apprentices receive appropriate direction, but also empower them to operate independently when ready,” Sherrard said.
“I want to thank industry for working with us on these new rules, your help has been invaluable to striking the right balance between regulation and allowing the industry to get on with the job.”
While supervisors are not required to be physically present on site, they must remain accessible via phone or other virtual means.
The revised framework is designed as a practical approach to improving supervision and workmanship standards, while acknowledging ongoing shortages of licensed plumbing supervisors across the industry.
Need for supervision
Earlier this year, Building Commission NSW conducted a targeted compliance blitz after inspections across the state identified widespread non-compliance with supervision requirements.
During one inspection in Port Macquarie, five apprentices were found working without supervision, resulting in a $1,500 fine for the licensed plumber responsible.
The compliance campaign resulted in six penalty infringement notices being issued, along with six education letters to employers outlining their supervision obligations.
Development of the SRI occurred alongside consultation with peak plumbing bodies, which raised concerns that the previous supervision rules were unclear and risked hindering productivity without delivering meaningful improvements in work quality.

The updated supervision standards aim to strike a balance between maintaining regulatory standards and enabling the plumbing industry to continue meeting demand during the ongoing housing crisis.
The SRI will remain in effect until 31 January 2028, allowing time for industry participants to obtain the required certificates under the Home Building Act and for broader legislative reforms to be considered if necessary.
