The enhanced BASIX tool is here

03 October 2023


The enhanced BASIX tool is now live! All users can now access the tool via the NSW Planning Portal (the Portal).  

The launch of the enhanced tool coincides with the commencement of the State Environmental Planning Policy (Sustainable Buildings) and the higher BASIX standards, effective from 1 October 2023. 

Migration of BASIX user accounts 

Individual and business BASIX user accounts and their associated “in progress” and completed BASIX certificates were migrated to the Portal. BASIX education, certifier and council user accounts were not transferred to the Portal.

Migrated users can access their:

  • “In progress” BASIX applications (projects) from the Active work dashboard of the NSW Planning Portal, provided they have been accessed on or after 1 January 2021; and
  • Completed BASIX certificates created on or after 28 March 2009 from the BASIX historical work dashboard. This dashboard is accessed through the top left-hand side menu of the Portal dashboard.

What’s changed 

The enhanced BASIX tool is now integrated into the Portal, and things might look a little different from the old tool.

Here are some tips to help you navigate the BASIX tool easily:  

  • You can create a new BASIX application by selecting BASIX from the “Select a digital service” list on the dashboard, then clicking “Create new”.
  • All BASIX applications created within the Portal will have reference numbers with the following prefixes: “BSX” for a single or multi dwelling project and “AL” for an alteration or addition project.
  • Your completed BASIX certificates migrated from the previous tool can be accessed from the BASIX historical work dashboard, located in the main menu.
  • If you revise or copy a migrated BASIX certificate, they will appear in your Active work dashboard and a NSW Planning Portal reference number will be generated.  
  • Once an “in progress” application (project) is moved to the completed stage, that is a BASIX certificate is generated, the application will move to the Completed work dashboard. 
  • The dashboards have filters to help you locate a specific application / BASIX certificate.
  • If you access your “in progress” BASIX application through the advanced search function at the top of your dashboard, the certificate will open in read only mode. To activate the application, go to the actions menu and select the option that refers to the last section you used. Note: If you open an “in progress” application via the dashboard it will automatically open in edit mode.  

How to access BASIX 

  1. Register for a NSW Planning Portal account to start your application.
  2. Log in to view your existing BASIX certificates or complete the online application form.

Note: You will only be able to create a BASIX report or BASIX certificate if you have an applicant or developer NSW Planning Portal user account.
