In Victoria, loyal customers are paying about 19 percent, or $291 more annually than those who switch, while in New South Wales, the difference is 15 percent, or $297, and South Australians face the largest disparity at $334.

Government interventions have played a significant role in reducing electricity prices, with federal and state governments contributing to a 17 percent drop in costs in the three months leading up to September 2024.

The ACCC encourages Australians to utilize resources like the Energy Made Easy or Victoria Energy Compare websites to identify better energy plans, especially during the holiday season.

The Australian Competition and Consumer Commission (ACCC) has issued a warning to consumers about the potential financial pitfalls of sticking with outdated electricity plans, advising them to inquire with their providers about cheaper options.

According to the ACCC's report released today, customers who do not update their energy plans are overpaying by an average of $317 annually compared to those who actively shop around for better deals.

Specifically, households on plans older than one year are estimated to be paying $238 more per year than those on newer plans.

The report highlights that households willing to switch providers can save approximately 17 percent more on their energy bills than those who remain loyal to their current plans.

Electricity companies are required to inform customers of cheaper plans available every three to four months on their bills, yet many consumers still miss out on savings.

Treasurer Jim Chalmers noted that the report reflects the effectiveness of government measures to alleviate electricity costs, citing increased competition among retailers and improvements in international energy markets.

The longer customers remain on older plans, the greater the 'loyalty penalty' they incur, which leads to higher costs for energy use.

Despite a decrease in annual electricity prices, many households still pay above the government safety net price, which serves as a reference for comparing plans.

The complexity of pricing, particularly with the rollout of smart meters, adds to the challenges consumers face in trying to lower their electricity bills.
