Notifiable work for plumbing and drainage

Notifiable work compliance

We want to ensure that plumbing, drainage work continues to be performed at a high standard so we regularly conduct compliance audits and checks on notifiable work and the accompanying paperwork.

What happens during an audit?

We may request documents and check:

  • that forms have been registered correctly
  • whether you have the right licence and/or endorsements to carry out the work
  • whether the work complies with relevant legislation and standards
  • whether you have given the owner/occupier a copy of the Form 4

Local governments and compliance

Local governments may also audit notifiable work within their region. They will generally target notifiable work which has a higher risk of non-compliance. 

The licensee or owner/occupier may also contact the local government directly to request an inspection of the work. If this inspection is not within the scope of an audit program, an extra cost-recovery fee may be charged.


There is a range of penalties that may apply where a licensee performs work that is non- compliant, defective, or performed without an appropriate licence. Additionally, a local government may issue a defect notice if they find non-compliant plumbing and drainage work.

If local government issues a compliance notice, they will negotiate a time with you to rectify the work. Penalties apply for non-compliance.

There are increased penalties for individuals who repeatedly place Queenslanders at risk by performing either unlicensed or non-compliant plumbing work and for offences that endanger health and safety. Individuals who persist in performing work without a licence or licensees who repeatedly direct or supervise unlicensed work will face increased penalties for second and third convictions. They may also face up to one year in jail for a third conviction.
