QBCC Notifiable Work — Complete List for Plumbers (2026)
What Is Notifiable Work in Queensland?
Under the Plumbing and Drainage Act 2018, certain types of plumbing work are classified as "notifiable" — meaning you must lodge a Form 7 compliance certificate with your local council within 5 business days of completion.
Get it wrong (or forget), and you're looking at penalties up to $13,345 per offence.

The Grey Areas
The most common mistake: replacing a hot water system and assuming it's "maintenance." If you're connecting new pipework or changing the location, it's notifiable. When in doubt, lodge the Form 7 — it's free to lodge and protects your licence.
