Avoid common notifiable work errors

There are three important points to remember about registering your notifiable work (Form 4/4A) correctly:

• register within 10 business days after the work is finished
• register each time you issue an invoice for notifiable work (including where a job has progress payments)
• always provide a copy to the owner/occupier where the work is being carried out, or the person who requested the work

Some types of plumbing work may appear to be notifiable work but actually fall into a different category, such as permit work. 

Check that you know what category of plumbing and drainage work you are undertaking. Use our online tool:

Is this notifiable work?

Example

The installation of new fixtures in buildings connected to a combined sanitary drain is often mistaken for notifiable work. As the new fixtures may increase the load on the combined drain and affect other properties, it becomes compliance permit work.

In this case, you need to submit a  Permit work application form for plumbing, drainage and on-site sewerage work to the relevant local government, as well as, obtaining a permit and arranging required inspections.
 

Include an as-constructed diagram with your notifiable work (Form 4/4A), if the work you are doing involves underground sanitary drainage for any of the following:

• class 1a or 1b detached house
• class 1a townhouse
• class 10a shed or outbuilding.

This is a mandatory attachment in the online notifiable work Form 4/4A in myQBCC, and you can't complete your submission without one. For users of the manual registration method, the responsible person must ensure the as‑constructed drawing is attached to the Form 4/4A with payment details completed.

The as-constructed diagram must show:

• the location (where relevant) of fixtures and inground sanitary drains affected by the work
• each access point for cleaning and maintaining the work
• any reflux valve installed as part of the work
• dimensions of sanitary drains from key allotment features (e.g. buildings and boundaries) affected by the work
• depths and setbacks of any pipes, fixtures or apparatus installed.

If you have only repaired, serviced or maintained a testable backflow prevention device or dual check valve with atmospheric port, this is classified as minor work only.

Inspecting or testing a backflow prevention device is also minor work, however you must also send a Form 9 to the relevant local government within 10 business days. 

If you've undertaken work necessary for installing, replacing or removing a testable backflow prevention device or a dual check valve with atmospheric port, this is notifiable work. We also recommend attaching a copy of the Form 9 to QBCC when registering your notifiable work.
