Energy comparison is most useful when you enter your postcode and recent electricity or gas usage, rather than relying only on advertised rates. Compare the estimated annual cost, supply charges, usage rates, tariff type, conditional discounts, solar feed-in tariffs and any exit or connection fees. Check whether the plan suits your home, such as a controlled-load tariff for hot-water systems or time-of-use pricing if you can shift usage to cheaper periods. Prices and eligibility can vary, so confirm the offer and contract details with the retailer or through the Australian Government’s Energy Made Easy service.
