If you are with AGL, Origin or EnergyAustralia in Victoria, your market offer price changed on 1 August 2026. On average, AGL customers saw a 4.1% drop, Origin customers a 2% drop, and EnergyAustralia customers a 0.4% rise. That is a month later than every other state, where the big three changed prices on 1 July alongside the annual Default Market Offer reset.
What actually changed
These are average changes across all tariff types for existing customers, not a guaranteed number for your bill. Some households will see a bigger drop than the average, some will see a smaller one, and low-usage households in particular can end up worse off if their retailer has shifted more of the bill onto the daily supply charge rather than the usage rate. The only way to know what it means for you is to check your own price change notice or your next bill against what you were paying before.
This follows the Victorian Default Offer change on 1 July, which cut the regulated default price by about 5% on average for the roughly 17% of Victorian households still on a standing offer.
A new rule aimed at the "loyalty tax"
From 1 July 2026, Victorian retailers must check at least once a year that customers who have been on the same plan for four years or more are paying a reasonable price, and move them onto something cheaper if not. The Essential Services Commission estimates this could shift up to 53,000 households onto better plans, worth about $12.2 million in total, or roughly $230 per affected household a year.
Our take
A one-off correction for long-term customers is welcome, but it is not the same as your retailer finding you the best deal every year. The regulator's own data shows 61% of Victorian customers are not on their provider's cheapest plan, despite that message appearing on page one of every bill. Waiting for a rule to move you is a much smaller win than comparing the market yourself: analysis of current plans shows households on the AusNet network could save around $385 a year, and CitiPower households around $327, by switching from the default offer to the cheapest flat-rate plan available rather than sitting on it.
What to do
Check your next bill against your old rate, don't assume the average change quoted in the media is what landed on your account, and compare your plan against the market regardless of which way your price just moved. If you have been with the same retailer for four years or more and haven't heard from them about a price review, it is worth asking directly.
