For Victoria plumbers and handymen

Who regulates plumbing

Building and Plumbing Commission (BPC). Replaced the Victorian Building Authority (VBA) on 1 July 2025.

The Building and Plumbing Commission began on 1 July 2025, bringing together the functions of the VBA, Domestic Building Dispute Resolution Victoria and the domestic building insurance arm of the VMIA. Victorian plumbers hold either a registration or a higher-level licence in each class of work, and only a licensed plumber can sign a compliance certificate.

Paperwork that applies

• A licensed plumber must issue a compliance certificate when the total value of the work, including materials, appliances, labour and GST, is more than $750.
• The certificate is issued within five days of completing the work.
• Compliance certificates bought from 22 September 2025 expire 12 months after purchase, so unused stock needs watching.

Handyman licence limit

More than $10,000 needs a licence or registration

Domestic building work costing more than $10,000, including labour and materials, needs a builder registered with the BPC, and the same value triggers a major domestic building contract.
