Complaints received (all industries)

January-March 2025 to January-March 2026

Complaint numbers for the January to March 2026 quarter continued at an elevated level compared to the same quarter in 2025. Complaints that factor in consumer energy resources (CER) such as rooftop solar and batteries have significantly increased and this may have links to the rollout of residential batteries through the Commonwealth Government’s cheaper home battery program.

Customer complaint issues

High bills remained the most common complaint issue this quarter. Eight of the top ten core complaint issues were about billing. A credit issue relating to payment difficulties also featured in the top ten. It is no surprise that billing and credit issues remain the main drivers of complaints. New South Wales households were already dealing with cost-of-living pressures, before petrol and diesel prices dramatically increased this quarter.

Consumer energy resources complaints

EWON received 911 electricity complaints where the customer mentioned that consumer energy resources (CER) were a factor in their complaint. This includes technologies like rooftop solar and residential batteries.

The second highest core complaint issue related to the performance of the customer’s CER system, specifically that there was a fault with the technology.

This increase in complaints related to CER is likely related to the significant uptake of rooftop solar systems and residential batteries after the launch of the Commonwealth Government’s Cheaper Home Batteries Program. From 1 May 2026, the rebate for solar batteries will:

  • decline every six months at a higher rate
  • be tiered based on battery system size.

This will impact the number of small-scale technology certificates a solar battery may be eligible for, particularly for larger sized systems. We anticipate that these changes to the Commonwealth scheme may drive new complaints across the energy sector.
