Start by checking your bill for annual usage, rates, supply charges, discounts, solar credits and any controlled-load charges. Use the Australian Government’s Energy Made Easy comparison tool, or your state or territory’s approved service, and enter details from your bill for a more meaningful comparison. Look beyond the headline discount, as rates, fees, contract terms and estimated annual costs can differ between retailers. Results are estimates based on the information provided, so confirm the offer, including any eligibility requirements, directly with the retailer before switching.
