An energy retailer sends your bills and sets the plan’s rates, discounts and fees, while the local distributor maintains the poles, wires and gas network. Compare the estimated annual cost—not just the headline discount—and check usage, supply charges, contract terms, late-payment fees, solar feed-in rates and any exit costs. You can compare available electricity plans through the government’s Energy Made Easy website, or Victorian Energy Compare in Victoria. Before switching, check whether your concession or hardship arrangements will continue and confirm details with the retailer or the relevant government department.
