Compare the estimated annual cost using your actual usage, not just the advertised discount or headline rate. Check daily supply charges, usage rates, tariffs, conditional discounts, contract terms, exit fees and any solar feed-in tariff that applies. Your bill and the retailer’s Energy Price Fact Sheet can help you compare like for like. Final prices depend on your address, meter, usage and retailer, so check the relevant state comparison service or energy.gov.au before switching.
