Plumbing registration and licences

To do plumbing work in Victoria, you must be one of the following:

  • licensed by the VBA
  • registered by the VBA (or have provisional registration) and working under the supervision of a licensed plumbing practitioner


  • in training under the supervision of a licensed plumbing practitioner.

A licensed plumber has a higher standard of knowledge and experience than a plumber who is registered or in training. They are able to issue a compliance certificate to consumers, to certify that their work complies with the relevant plumbing standards, codes and regulations. And they hold insurance that protects the consumer in the case of defective plumbing work.

If you are not registered or licensed, or in training, then you face significant penalties for doing plumbing work.

You need to be registered or licenced in every class of plumbing work that you intend to do.
