Activities to minimise harms - unregistered and unlicensed practitioners

New online form to help identify unregistered and unlicensed practitioners

The Building and Plumbing Commission (BPC) is committed to protecting consumers by targeting unregistered and unlicensed practitioners in the building and plumbing industries. We’ve launched a new online tip-off form to make it easier for both consumers and practitioners to report suspected unregistered or unlicensed individuals.

How to report unregistered or unlicensed work

If you suspect unregistered or unlicensed building or plumbing work, please use our Tip-off Form to report it and help us protect consumer safety and maintain industry compliance.

How it works

Once a tip-off is submitted, the BPC will assess the report, prioritising cases deemed high risk. Enforcement action will be taken against those found to be operating outside regulations to protect consumers and maintain industry standards.

Please note, we will assess each submission, however, we will not reply unless more details are required. 

Want to file a formal complaint?

If you wish to lodge a formal complaint regarding someone performing unregistered or unlicensed work, and to receive a response from the BPC about this, then please visit the Issues, complaints and disputes page for more information.

Why we’re doing this

Unregistered and unlicensed work can lead to unsafe practices and compliance issues, putting consumers at risk. As part of our harm-based regulatory approach, we’re using our full legislative powers to protect consumers and ensure compliance across the industry.

When to hire a registered or licensed practitioner

  • Builders: For domestic building work over $10,000 or projects involving structural changes (e.g., home extensions, renovations), homeowners must hire a registered builder.
  • Plumbers: Only licensed plumbers, or registered plumbers working under the supervision of a licensed plumber, can legally perform specific plumbing work such as water connections, gas fitting, roofing (stormwater), and underground drainage.

    For any plumbing work exceeding $750, a licensed plumber is required to issue a compliance certificate so that the work complies with relevant safety standards and plumbing regulations. These certificates also provide additional protection to homeowners through insurance coverage. Note: Registered plumbers cannot supervise others or issue compliance certificates.

FAQs

How long will it take to complete the form?

Completing this form should take only a few minutes.

Can I remain anonymous?

Yes, but keep in mind that we won’t be able to contact you for further details if required.

How to make a good tip-off?

When reporting known or suspected unregistered or unlicensed work, the more information you give us, the better we can investigate. Even if you only know partial details or can only complete some sections of the form, this information is still very useful.

Useful information includes:

  • information about actions or activities you think, or suspect are unregistered or unlicensed work, including how and when it occurred, and site address or location.
  • details about the person/s involved, such as names, phone numbers, addresses, and relevant organisation.
  • advising if the person you've identified is working on site now.

We ask for your contact details in case we need further information. However, you can choose to remain anonymous.

If you have photographs or other evidence and are willing to be contacted, please indicate this on the form.

What happens after I submit a tip-off?

When we receive information through a tip-off, we cross check the information and assess whether further action is required.

 Due to the circumstances of a tip off, we will not be able to tell you of the outcome of our investigation or provide progress updates.

If you prefer to obtain these, please consider lodging a complaint via the BPC Complaints Process page.

Rest assured we take all reports seriously. If we find enough evidence of unregistered or unlicensed work, we may take further steps to prosecute those involved for breaches under the Building Act 1993.

How does the BPC use personal information?

The BPC will collect, hold and use personal information through the online tip-off form to carry out its responsibilities under the Building Act 1993 (Vic) and other laws relating to the business of the BPC.

We do not use or disclose your personal information for purposes other than what it was collected for, unless permitted or required by law. We only collect information from you that is necessary to carry out our functions, from you directly, if practicable.

Please refer to the BPC Privacy Statement for more information about this.
