Your electricity cost usually includes a daily supply charge and a usage rate for each kilowatt-hour (kWh), with prices varying by state, tariff, retailer and household usage. Time-of-use plans may charge different rates throughout the day, while discounts and solar exports can also change the total bill. Compare available offers using the Australian Government’s Energy Made Easy website, where you can enter details from a recent bill. Check the retailer’s current rates, fees and contract conditions before switching, as the cheapest option depends on your circumstances.
