Plumbing Audits

The Victorian Building Authority (VBA) conducts risk-based compliance audits and inspections of plumbing work throughout Victoria.

Compliance Auditors conduct on-site audits of a sample of plumbing work for which a compliance certificate has been lodged. The Auditor’s role is to ensure the plumbing work complies with all relevant plumbing laws.

The compliance certificates to be audited each month are selected using risk-based criteria.

The plumbing audit process

Audits are conducted by qualified persons authorised by the VBA. All Auditors display identification cards.

If the work certified is selected for a risk-based audit, the licensed plumber will be contacted by the VBA. The licensed plumber will be asked for details of the work performed and will need to arrange a suitable time with the property owner for a risk-based audit to be undertaken.

Risk-based audits are usually carried out between 7:30am and 3:30pm, Monday to Friday, and take around 30 minutes to complete, depending on the complexity and size of the plumbing installation.

The licensed plumber must meet the Auditor at the agreed time, provide access to the entire installation and have a copy of the compliance certificate (or certificates) and any other relevant documentation when the audit is conducted. If the plumbing work involves roofing, the licensed plumber must provide safe access.

If a specific test is required during the audit, such as gas pressure test for the installation of a new gas fitting line, the licensed plumber will be required to attend the risk-based audit with all relevant testing equipment and fitting line must be under test.

If the plumbing installation is large or complex, the licensed plumber should advise the Auditor when arranging the risk-based audit, in order to ensure sufficient time is allocated.

The Auditor will work to an Audit Checklist specific to each class of plumbing.

What happens if my work does not pass a risk-based plumbing audit?

If the risk-based audited work is found to be non-compliant, the licensed plumber will be advised of non-compliant issues requiring rectification in the form of a rectification notice.

If time permits, and only at the Compliance Auditor’s discretion, the non-compliant plumbing work may be rectified in the presence of the Compliance Auditor at the time of the risk-based audit to prevent a rectification notice being issued. This action will be documented by the attending Compliance Auditor.

The rectification notice provides a timeframe of 14 days to complete rectification. If more time is required for specific reasons, the VBA should be contacted for an extension request. The work will be re-audited when completed.

If a licensed plumber has concerns about the audit process, they should contact the VBA on 1300 815 127 to speak with a Plumbing Audit Team Leader about their concerns or email

If a licensed plumber receives a rectification notice and disagrees with the decision of a VBA Auditor, he or she may apply to VCAT within 5 days of the date of issue of the notice to have the decision reviewed.
