Your electricity bill usually shows the billing period, meter readings, electricity use in kilowatt-hours (kWh), and the price charged for each unit. It may also include a daily supply charge, discounts, solar feed-in credits, GST and any overdue balance. Check whether the meter reading is actual or estimated, and compare your usage with earlier bills to spot changes. Your retailer’s bill should explain the tariff and payment options; contact the retailer if anything looks incorrect. If you hold an eligible concession card, check the relevant state or territory government website for available energy concessions.
