Do I Need a Form 4 or Plumbing Permit in Fraser Coast, Queensland?

Updated: Aug 31
Planning a bathroom renovation, kitchen renovation or plumbing work in Hervey Bay or the Fraser Coast? You may be wondering whether your plumbing work requires a QBCC Form 4, a council plumbing permit, or no additional approval at all.
Queensland plumbing and drainage work is divided into different categories, including notifiable work, permit work and minor work.
The requirements depend on the type of property and the plumbing work being completed.
At CNL Plumbing & Drainage, we take care of the applicable plumbing compliance requirements associated with the work we undertake and can advise you before your project begins.
What Is Form 4 Plumbing in Queensland?
A Form 4 is used by licensed plumbers and drainers to register notifiable plumbing and drainage work with the Queensland Building and Construction Commission (QBCC).
Notifiable work generally includes plumbing alterations and additions to existing buildings that don't require a local government plumbing permit before work begins.
Common examples can include:
Bathroom renovations.
Kitchen renovations.
Relocating a toilet, shower, basin or kitchen sink.
Installing new plumbing fixtures.
Altering or extending existing water supply pipes.
Altering existing sanitary plumbing or drainage.
Installing or replacing a hot water system.
Installing or replacing certain temperature control devices.
Certain backflow prevention work.
Your licensed plumber completes the applicable work and registers the notifiable work with the QBCC.
Does a Bathroom Renovation Need a Form 4 in Queensland?
Often, yes.
Bathroom renovations commonly involve altering existing plumbing or relocating/installing fixtures such as:
Toilets.
Showers.
Baths.
Basins.
Vanities.
Water supply points.
Waste and drainage connections.
If the work falls within Queensland's definition of notifiable work, your plumber is responsible for registering the applicable work with the QBCC.
This provides an official record that notifiable plumbing or drainage work has been carried out at the property.
When Is a Plumbing Permit Required in Queensland?
Some plumbing and drainage work requires a plumbing permit from the relevant local government before work begins.
Permit work can include:
Plumbing and drainage associated with construction of a new building.
Certain new home plumbing and drainage installations.
Certain commercial plumbing and drainage projects.
Certain work involving combined sanitary drains.
Certain trade waste installations.
Work involving particular performance solutions.
Other plumbing or drainage work classified as permit work under Queensland legislation.
Permit work is generally assessed by the relevant local government and may require inspections at different stages of construction.
For projects in the Fraser Coast region, this may mean plumbing approvals and inspections are required as part of the broader building or renovation process.
Form 4 vs Plumbing Permit – What's the Difference?
The easiest way for homeowners to understand the difference is:
Form 4 / Notifiable Work generally applies to certain alterations, additions and installations involving plumbing and drainage in existing properties. The work is registered with the QBCC.
Plumbing Permit / Permit Work
Generally applies to plumbing and drainage work that requires local government approval before the applicable work begins, such as plumbing associated with new construction and certain other types of development.
Does Every Plumbing Job Need a Form 4?
No.
Not every plumbing job requires a Form 4 or council plumbing permit.
Some plumbing and drainage work is classified as minor work.
Examples can include certain:
Blocked drain clearing.
Repairs to damaged or broken pipes.
Plumbing maintenance.
Repairs to existing plumbing fixtures.
Replacement of existing fittings or fixtures.
Although minor work may not require a Form 4 or plumbing permit, work classified as regulated plumbing or drainage work must still be carried out by an appropriately licensed person.
Why Am I Being Charged for a Form 4?
If your plumbing work is classified as notifiable work, your plumber has a legal obligation to register the applicable work with the QBCC.
The Form 4 charge included with your plumbing works can cover the QBCC registration fee and the administration associated with preparing and lodging the required documentation.
It is not simply an optional certificate added to your plumbing invoice.
What Happens After a Form 4 Is Lodged?
Once notifiable work has been completed, the licensed plumber registers the work with the QBCC.
The Form 4 records information including:
The property where the work was completed.
The categories of notifiable plumbing work undertaken.
A description of the work.
The licensed person responsible for the work.
Relevant QBCC occupational licence details.
The homeowner, occupier or person who engaged the plumber is also provided with a copy of the applicable documentation.
Do I Need to Organise the Form 4 myself?
Generally, no.
When CNL Plumbing & Drainage undertakes notifiable plumbing work, we manage the applicable QBCC Form 4 registration associated with our work.
If your project instead requires plumbing approval through local government, we can identify this as part of planning the plumbing works and advise what needs to occur before the applicable work commences.
