Electricity prices are usually made up of usage charges (cents per kWh) and a daily supply charge, with GST and any discounts or fees affecting the total. Check whether a plan has flat, time-of-use or controlled-load rates, and compare estimated annual costs using your actual usage rather than headline rates alone. Prices and available plans vary by state, distributor, meter and household circumstances, so solar exports, concessions and payment options may also matter. Use the Australian Government’s Energy Made Easy comparison tool, or ask retailers for a current fact sheet, and check the offer’s terms before switching.
