You must first ensure your business is linked to the Principal or Subcontractor. This is typically initiated by the Principal or Lead contractor sending you an invitation to register by email.

As a subcontractor to a Principal or Lead Contractor you ONLY need to register your business name, which is free of charge. You are not required to provide evidence of insurances or complete a Safety and Environment Management System (SEMS) review.

To ensure you register as a subcontractor ensure you answer the ‘Classification’ questions as follows:

‘Are you being engaged by Transgrid. If you are being engaged by Transgrid you will be invoicing Transgrid directly?’ Answer No
