Use a recent bill to compare your usage, daily supply charge, usage rates, discounts, fees and contract conditions—not just the advertised percentage off. Check whether rates vary by time of day, as a plan that suits one household may cost more for another. In most of Australia, the Australian Government’s Energy Made Easy website lets you compare available plans using your postcode and usage; Victorian households can use Victorian Energy Compare. Before switching, confirm any exit fees, concessions and solar feed-in terms with the retailer, as your final savings depend on your circumstances.
