Many Australian households and small businesses are bracing for potential electricity bill shocks from July 1, 2026, as energy retailers are reportedly increasing daily fixed supply charges, despite the Australian Energy Regulator (AER) and Essential Services Commission (ESC) announcing default price reductions for the new financial year. The disparity has prompted Energy Minister Chris Bowen to refer retailers to the Australian Competition and Consumer Commission (ACCC) and AER for investigation into potential misconduct.

This development comes as consumers begin to receive notifications from their energy providers, revealing changes that could see some low-energy users facing higher overall bills, directly contradicting the expected savings touted by regulators.

Default Price Cuts Announced

In late May 2026, the AER released its final Default Market Offer (DMO) determination for 2026-27, setting benchmark prices for customers on standing offers in New South Wales, South East Queensland, and South Australia. The determination confirmed lower default electricity prices for most regions from July 1, 2026.

Specifically, residential flat rate standing offer prices were projected to fall between 3.4 per cent (approximately AUD$66) and 5.0 per cent (approximately AUD$137) in New South Wales, and by 7.2 per cent (approximately AUD$155) in South East Queensland. Small businesses in these regions were set for even larger reductions, with prices decreasing from 9.0 per cent (AUD$432) to 20.9 per cent (AUD$1,303) in NSW, and 10.4 per cent (AUD$445) to 14.0 per cent (AUD$601) in South East Queensland, depending on tariff type.

However, South Australian residential flat rate DMO customers were an exception, facing a modest increase of 1.4 per cent (AUD$33). For those on time-of-use DMOs, prices were set to decrease by 1.1 per cent (AUD$25). Small businesses in South Australia, however, would see reductions between 6.8 per cent (AUD$379) and 12.1 per cent (AUD$673).

Separately, Victoria’s Essential Services Commission (ESC) announced a 5 per cent average reduction (AUD$84 annually) for households on the Victorian Default Offer (VDO) and a 6 per cent average reduction (AUD$241 annually) for small businesses, also effective from July 1, 2026.

The Fixed Charge Controversy

Despite these announced reductions, reports emerging this week indicate that some energy retailers are significantly increasing their daily fixed supply charges. These charges apply regardless of energy consumption and, in some instances, have reportedly surged by up to 86 per cent.

This shift in pricing structure means that while per-kilowatt hour usage rates might be decreasing, the higher fixed daily charges could lead to an overall increase in bills, particularly for households and small businesses with lower energy consumption. Canstar estimates suggest some average households could see an annual bill rise of up to AUD$32, even as others experience drops of up to AUD$174, depending on their location and consumption patterns.

Energy Minister Chris Bowen publicly addressed the issue, stating on Wednesday, June 25, 2026, that he has requested the AER and ACCC investigate these practices. “We’ve seen some companies – not all, far from it – choose to increase their fixed supply costs while reducing their per-kilowatt hour costs,” Minister Bowen noted.

This concern is amplified by the fact that the DMO acts as a safety net and a reference price, meaning market offers from retailers are benchmarked against it. While retailers are not bound to replicate the DMO’s tariff structure, significant deviations, particularly those impacting overall bill costs negatively for consumers, are now under regulatory scrutiny.

What This Means for Your Bill

For the approximately 10 per cent of residential customers and 15 per cent of small business customers still on standing offers, the DMO and VDO changes will apply automatically. However, the vast majority of Australians are on market offers, where retailers set their own prices. It is within these market offers that the reported increases in fixed supply charges are causing concern.

Consumers are urged to be vigilant and proactively review their energy plans. Many retailers introduce new plans around July 1, making it a critical time to compare offers. “If you haven’t switched in a while, you’re likely paying more than you should,” advises industry commentators.

New Solar Sharer Offer for Smart Meter Homes

Amidst the pricing complexities, the AER’s DMO determination for 2026-27 also introduced the new Solar Sharer Offer, available from July 1, 2026. This opt-in plan provides eligible households with smart meters in DMO regions (NSW, SA, SE QLD) with three hours of free electricity in the middle of every day.

The Solar Sharer Offer is designed to benefit households both with and without rooftop solar, encouraging a shift in energy use to capitalise on abundant daytime solar generation and potentially reduce overall bills. The price of this offer will be regulated, mirroring the time-of-use DMO in each area, to ensure consumer confidence.

While the Solar Sharer Offer presents an opportunity for savings, the broader issue of rising fixed charges highlights the need for consumers to actively engage with their energy plans. Comparing offers, understanding the breakdown of supply and usage charges, and leveraging comparison websites remain crucial strategies for managing electricity costs in 2026.
