Compare the usage, supply charge, tariffs, discounts, fees and billing period on your current bill, rather than relying only on the total amount. Enter your address and recent gas usage into the Australian Government’s Energy Made Easy website, or Victorian Energy Compare if you live in Victoria, to review available plans. Check whether discounts are conditional, and consider estimated versus actual meter readings and seasonal usage. Prices and eligibility can change, so confirm the offer, fees and contract details with the retailer before switching.
