When comparing an energy retailer in Sydney, check the estimated annual cost for your postcode, usage pattern and tariff type—not just the advertised discount. Compare rates, daily supply charges, contract terms, exit fees, billing options and customer support through the Australian Government’s Energy Made Easy website. If you receive an eligible concession, check how it may apply with the retailer and NSW Government. Your best option depends on your circumstances, and retailers can confirm current plans, prices and eligibility before you switch.
