Start by checking your bill and comparing your current plan with other offers using the Australian Government’s Energy Made Easy website, or Victorian Energy Compare in Victoria. Reduce usage by improving heating and cooling efficiency, switching off standby appliances, using energy-efficient lighting and washing clothes in cold water. Ask your retailer whether a time-of-use tariff, payment plan or available hardship support could suit your circumstances, as changing plans is not always cheaper for every household. If eligible, check your state or territory’s energy concessions through the relevant government website.
