Make a complaint against a contractor
If you believe that a contractor is breaking the law and you have evidence, you can send in a complaint. You can lodge your complaint online or download the Notification of Offence Form (PDF). Before you begin, see the ‘Complaints we don’t investigate’ page.
Also, be aware that we can’t investigate every complaint. To make the best use of our resources, we focus on areas where there is evidence and where consumers will be most at risk.
Time limits for complaints
To allow for investigation time, please make complaints relating to :
- Contractual issues (Domestic building contracts) – The offender must be prosecuted within 3 years of committing the offence, or 2 years from the date QBCC first became aware of the offence (whichever is later).
- Building work and all other offences (QBCC Act offences) – within 21 months of the offence date, or within 9 months from when you notify QBCC of the offence. The offender must be prosecuted within 3 years of committing the offence, or 2 years from the date QBCC first became aware of the offence (whichever is later).
