Plumbing codes and standards

The Victorian Building Authority (VBA) regulates Victoria’s plumbing practitioners and plumbing work.

The three key documents which form the plumbing regulatory framework in Victoria are:

Building Act 1993

The Building Act 1993 sets out the requirements for building and plumbing work in Victoria.

Part 12A of the Act sets out the legal framework for the regulation of plumbing work and plumbers. This includes:

  • licensing and registration of plumbers
  • restrictions concerning the carrying out of plumbing work
  • compliance certificates
  • inspection requirements for sanitary drainage work
  • insurance orders
  • rectification of defective plumbing work
  • modification of plumbing regulations
  • powers of the VBA’s enforcement staff (plumbing inspectors and compliance auditors)
  • plumbing infringement notices
  • plumbing inquiries and disciplinary action
  • incorporation of the Plumbing Code of Australia into the regulations.

Plumbing Regulations 2018

The Regulations commenced on 18 November 2018, replacing the Plumbing Regulations 2008.

In Victoria, all regulations 'sunset’ (expire) after ten years and undergo a comprehensive review to ensure they remain fit for purpose and continue to meet their intended objectives.

The Regulations cover for the following aspects of plumbing work in Victoria:

  • define the scope of work for all classes of plumbing work and specialised plumbing work
  • set out the qualification and experience eligibility requirements for registration and licensing in each class of plumbing work and specialised plumbing work
  • set fees payable for registration and licensing applications and the price of a compliance certificate
  • set out additional technical requirements with which work performed in specified classes of plumbing must comply, including some variations from the requirements in the PCA.

National Construction Code – Plumbing Code of Australia

The National Construction Code (NCC) combines building and plumbing construction requirements into a single code.

The NCC is produced and maintained by the Australian Building Codes Board (ABCB), which is a joint initiative of federal, state and local governments (the Council of Australian Government, or COAG).

The NCC consists of the Building Code of Australia (Volumes One and Two) and the Plumbing Code of Australia (Volume Three).

  • Volume One: relates primarily to Class 2 to 9 buildings.
  • Volume Two: relates primarily to Class 1 and 10 buildings.
  • Volume Three: relates primarily to plumbing and drainage associated with all classes of buildings. Also known as the Plumbing Code of Australia (PCA).

The PCA contains the technical requirements for the design and construction of plumbing and drainage systems in new and existing buildings. Volume 3 applies to all classes of buildings whenever plumbing work is carried out. The PCA also applies to sites where water services are constructed independent of buildings.

The NCC is updated and re-published every three years. The PCA 2019 came into effect in Victoria on 1 May 2019.

For information about the PCA 2019 changes, see our Summary of PCA 2019 changes (PDF, 329.19 KB). For answers to common questions about the changes, see NCC 2019 Plumbing FAQs.
