For an energy comparison in Sydney, compare the usage and supply rates, not just the advertised discount or estimated annual cost. Check whether the plan suits your tariff type, solar exports, controlled load and typical usage, and look for conditions such as bill-payment requirements or fixed-term fees. Your postcode and household usage can significantly affect which offer is cheapest, so use your latest bill for a more accurate comparison. The Australian Government’s Energy Made Easy website provides independent comparisons, while the retailer can confirm current prices and plan terms.
