An electricity bill usually shows your billing period, meter readings, usage in kilowatt-hours (kWh), and the amount charged for each tariff. Common charges include usage, a daily supply charge, GST, and any discounts, credits or government concessions that apply to your account. It may also list solar feed-in credits, estimated readings, payment due dates and your retailer’s contact details. Compare the current and previous readings and check whether the bill is based on an actual or estimated meter read. If something looks wrong, contact your retailer and ask for a bill explanation or payment support.
