Compare the retailer’s estimated annual cost, usage rates, supply charges, tariffs, discounts, fees and contract terms—not just the headline offer. Check the Energy Price Fact Sheet and use the Australian Government’s Energy Made Easy comparison tool to compare plans for your postcode and household usage. If you have solar, review the feed-in tariff and any conditions, and check whether controlled-load rates apply. Before switching, ask about payment assistance, hardship support, billing options and exit fees, and confirm any offer details directly with the retailer.
