The application process
There are 5 steps in the application process:

We start assessing your application when it is complete (Step 3). Simple applications that have no issues or gaps to address can take around 2-3 weeks to complete. Our assessment will take longer if:
- the change is complex
- you need to provide more information
- you or a related entity have any current or pending compliance issues.
Step 1: You prepare your application |
Prepare your application and required information. For all applications, you must provide:
Submit one application for an accreditation covering all requested changes. If you wish to amend multiple accreditations, submit separate applications for each accreditation. |
Step 2: You submit your application |
Submit your application to IPART in TESSA (click on the 'Application for Amendment’ link on your dashboard). Any documents must be in commonly used file formats, such as Microsoft Word or Excel, Adobe PDF, JPEG, etc. If you are requesting a transfer of accreditation, the transferee must also have an account in TESSA. |
Step 3: We check your application is complete |
We will check you have provided all required information. If your application is incomplete, we will request the missing information, which must be provided before we can proceed. If you are requesting a transfer of accreditation, this step includes payment of the transfer fee (see Costs of being an ACP). |
Step 4: We assess your application |
We assess your application in accordance with requirements. We may request further information to enable our assessment. We typically issue no more than 2 requests for information. |
Step 5: We notify you of our decision |
When we have completed our assessment the Scheme Administrator will decide whether to approve or refuse your application. We will inform you of this decision in writing through TESSA. |
