Your electricity price and total cost depend on your usage, daily supply charge, tariff type, location and retailer. Time-of-use plans may charge different rates throughout the day, while some households may qualify for concessions or other support. Compare the estimated annual cost, rates and fees on your bills or through your state or territory’s authorised comparison service, rather than looking only at the advertised discount. Check the offer’s terms with the retailer, as the final bill depends on your circumstances and actual energy use.
