Industry News - Metering Contestability banner - heroImage2018116213544

In a continuing effort to assist and support the industry due to changes from Metering Contestability, we will be making further changes to REX on 8 November 2018.

This will provide retailers additional notifications relating to New Service Provision and Alteration of Service Provision applications.

REX will still be available to use. However, you may experience an interruption when we make the changes in the afternoon of 7 November 2018 (after 5pm).

What this means for retailers

From 8 November 2018, retailer REX users can opt in to additional email notifications throughout a New Service Provision or Alteration of Service Provision application lifecycle.


New email notifications for retailers

  • Allocate NMI required
  • Ready for appointment
  • Appointment bookings
  • Appointment cancellations
  • Knockbacks
  • Appointment reminders
  • Event-based bookings and cancellations, such as bushfire and storm events, that impact pre-arranged customer connect work


To begin with, all retailers will be opted in to all new communication points. Therefore, there’s nothing you need to do to start receiving these new email communications. They will be sent to the existing email address for energisation notifications.

Once you have received the new emails and determined what options are meaningful to you, you can change your opt in preferences by emailing our Retailer Relations contacts.

What this means for registered electricians

There will be no changes for registered electrical contractor REX users.

Further information

Updates to the REX user guides will be available on our REX page from 8 November 2018.

If you have any questions, you can email us at
