Queensland Drainer Licensing Overview
QBCC Regulatory Overview
Queensland Building and Construction Commission is Queensland's principal regulator for the building and construction industry, responsible for licensing all drainers who perform regulated work in the state. The QBCC issues and renews licences, sets minimum requirements for licensees, investigates complaints, and takes disciplinary action against non-compliant operators.
As of February 2026, Queensland Building and Construction Commission oversees 183 licensed drainers across Queensland, covering 2 licence classes. This represents one of the most comprehensive licensing regimes in Australia, designed to protect consumers and maintain industry standards.
Always check a drainer's licence class before signing a contract. Different licence classes authorise different types and scales of work. You can verify both their licence class and status on TradieVerify or the QBCC website.
