Start by checking your latest bill for electricity usage, supply charges, tariff type, discounts and any solar or controlled-load details. Use the Australian Government’s Energy Made Easy website to compare plans available at your address, using your actual annual usage where possible. Look beyond headline discounts and check the ongoing rates, conditions, fees and whether the estimate reflects your household’s usage pattern. Before switching, confirm the offer and costs directly with the retailer, as savings depend on your circumstances and future energy use.
