What licence type do you need? 

The QBCC licence type you require is determined by the type of work you need to perform. All mechanical services - air-conditioning and refrigeration work requires a licence. 

We offer four types of licence to cover different roles and responsibilities in the building industry. You must ensure that you only carry out building work covered by your licence type.

Please note, a company licence is required to operate as a company. When applying for a company licence, you must nominate a nominee supervisor who is licensed for the same scope of work. For more information, read our factsheet Companies and licensing (PDF). 

Occupational licences 

We encourage you to apply early to ensure you have the qualifications and experience to be licensed by the 1 January 2022 deadline. 

Apply now for extended renewal period 

Mechanical services employees who apply and have their licence granted sooner can benefit from a greater period of time before their first renewal date.  

Mechanical services occupational licences granted now will commence on 1 January 2022 rather than the date the licence is issued, meaning the first renewal date for these licences will be 1 January 2023. 

Note: eligibility for this extension of the renewal period is not available for those also applying for a nominee or trade contractor licence at the same time or existing licence holders.

All licensing applications require proof of identity and evidence of your technical qualifications.
