In Perth, most households buy electricity from Synergy under tariffs regulated by the Western Australian Government, rather than choosing from a wide competitive retail market. Your bill usually includes a daily supply charge plus a usage charge per kilowatt-hour, with the total depending on your tariff, consumption and any concessions. Prices and tariff settings can change, so check the current rates on Synergy’s website or the WA Government’s electricity pricing information. Compare the rates and daily charges on your bill with the official tariff, and contact Synergy if anything appears unclear.
