All BASIX certificates (projects) completed before 1 October 2023 are located in your BASIX historical work folder. When you open a BASIX certificate from this location it will be in read only mode.
To revise a BASIX certificate completed before 1 October 2023:
Log into the NSW Planning Portal.
Select the BASIX historical work folder from the left-hand side menu, activated by selecting the three horizontal lines.
The applications (projects) will be displayed on a dashboard. Select the relevant project and note the BASIX application reference number (which you should use instead of the project name).
Select the “Revision” button on the application banner.
A new reference number and application will be generated. The application will then be visible in your Active work tab. Complete the required information and calculate your scores.
