How to apply

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

Visit the Technical qualifications and experience for Mechanical Services – Medical Gas licence fact sheet to check if you have the required technical qualifications.

Alternative qualifications that aren’t listed in the Technical Qualifications document may be considered on a case-by-case basis

Recent amendments to the QBCC Regulation will allow applicants for some mechanical services licences to benefit from a broader scope of alternative pathways.

All prescribed qualifications for the Mechanical Services – Medical Gas licence are in the Technical Qualifications document. However, in most circumstances for all licence types, there is a provision that the QBCC can consider an alternate qualification as equivalent.

If your qualifications differ from those prescribed in the Technical Qualifications document, we encourage you to submit your application, requesting the qualification be considered equivalent.

For more information about the documents needed to support an application for each licence type, use the Journey fact sheet for mechanical services - medical gas (PDF).

For examples of the experience required, use the Mechanical Services – Medical Gas Experience fact sheet (PDF)

If you are applying for an Occupational or Site Supervisor licence and do not hold the relevant technical qualification, you may be able to use your experience and relevant qualification to satisfy the technical qualification requirements for the Mechanical Services – Medical Gas licence, this is known as an alternative qualification pathway. 

Due to recent amendments to the QBCC Regulation, transitional arrangements for the alternative qualification pathway has been expanded. For more information, see the  Transitional Arrangements for Mechanical Services – Medical Gas licence webpage. 

To rely upon the alternative pathway, you must be able to demonstrate six months’ experience in performing mechanical services – medical gas work and hold either:
