What has changed

We have updated three fact sheets: 

  • HEER

  • IHEAB heat pump water heaters 

What you need to do


ACPs should begin using the updated fact sheets as soon as possible and no later than Monday November 17, 2025. 

Make sure you provide the latest fact sheets to customers.

Links and document hubs

All links lead to the fact sheet’s ‘document hub’ on the ESS website.  A document hub stores the most recent update of a document. Using this link will ensure you always have the right version, and the link will stay the same for future updates.

A reminder that the HADR BESS2 Fact Sheet was updated on July 1, 2025. Make sure you’re using this version. 

What's new in the fact sheets

The updates include:

  • new information around doorknocking and heat pump warranties to reflect the recent ESS Rule and changes and PDRS Rule and changes
  • revised links to NSW Energy pages with third party search tools to help consumers compare offers.

We listened to your feedback and added:

  • clearer steps so that customers with concerns or questions about their upgrade speak to the installer first, then contact the ACP if they can't resolve the issues.
  • simple, easy-to-understand language.
