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. 

Use your experience  

Until 31 December 2021, those applying for an occupational licence for mechanical services – medical gas work have the opportunity to use an alternative qualification pathway which provides an option for those who may not have the required technical qualifications.
