Compare plans using your postcode and actual electricity or gas usage, rather than relying only on advertised discounts. Check the estimated annual cost, usage and supply rates, tariff type, solar feed-in rates, conditional discount rules, fees, contract terms and whether prices can change. The Australian Government’s Energy Made Easy service can help compare electricity and gas offers in many states and territories; Victorian households can use Victorian Energy Compare. Before switching, confirm the plan details with the retailer and consider whether the estimated cost reflects your household’s likely usage.
