Check the billing period, meter reading (including whether it is estimated), electricity usage in kWh, usage rates, daily supply charge and any discounts or concessions. Your bill should also show the amount due, due date and payment options, while solar customers may see a feed-in credit for electricity exported to the grid. If the bill seems unusually high, compare your usage with earlier bills and contact your retailer to ask about the reading, tariff or charges. You can also compare plans through the Victorian Energy Compare service or the Australian Energy Regulator’s guidance, depending on where you live.
