QBCC Form 4 Plumbing Compliance Certificate

We often receive questions from clients regarding why we charge them for Form 4. The straightforward answer is that it is required by law.

The Form 4 system for plumbing and drainage work has existed for over two decades.

Initially, licensed plumbers had to submit Form 4 to local authority plumbing inspectors. For those on the Gold Coast, this meant submitting the form to the City of Gold Coast’s Plumbing and Drainage section when replacing part of the sewer house drain, water main, or hot water service.

In 2012, legislative changes mandated plumbers lodge Form 4 with the Department of Housing and Public Works through the Plumbing Industry Council (PIC). This was the first time a fee was introduced for lodging a Form 4, which amounted to $25.90. In 2014, the Queensland Building and Construction Commission (QBCC) assumed responsibility for the Form 4 process as part of their role in overseeing occupational plumbing licensing.

Once Form 4 is submitted, it may be subject to a random compliance audit to ensure the work adheres to the Plumbing and Drainage Act 2018 and the Plumbing and Drainage Regulation 2019. This process guarantees that work is carried out to the highest standards, safeguarding everyone’s well-being, health, and safety.

Whywait Plumbing has always been a proponent of the Form 4 process, as it ensures that all work on your property is compliant and registered with both the QBCC and the City of Gold Coast. In the event of a significant insurance claim involving plumbing failure, an accessor can easily trace the work to confirm that it was performed legally and in compliance with regulations.

In essence, Form 4 serves to protect homeowners.

Which areas of plumbing & drainage work are classified as notifiable work?

The definitions of notifiable work were updated on 1 July 2019 to ensure clarity and usability and establish cost-effective plumbing laws and regulations for both plumbers and property owners.

Twelve primary categories of notifiable plumbing and drainage work necessitate a Form 4:

1. Extending water supply pipes – involves work on water reticulation pipes other than fire services in existing buildings.
2. Extending or removing a fire service – applies to class 2-9 buildings with development approval as per schedule 2 of the Building Act 1975.
3. Existing sanitary plumbing – pertains to work in existing buildings where sanitary plumbing is removed, replaced, altered, or extended.
4. Existing sanitary drainage – concerns work on existing class 1 to class 10 buildings involving extension, replacement, alteration, or removal of any part of the sanitary drain system (excluding a combined sanitary drain). This also applies to extensions or alterations to a class 1 building.
5. Temperature control devices – includes work with thermostatic mixing valves (TMVs) or tempering valves in existing buildings that require installing, replacing, or removing a valve. This also applies to extensions or alterations to a class 1 building.
