Use a default market offer checklist to compare the plan’s estimated annual cost with the reference price, and check whether the estimate matches your household’s usage. Confirm the supply charge, usage rates, tariff type, solar feed-in tariff if relevant, and any discounts or conditions. Read the contract for fixed-term dates, exit fees, late-payment fees, billing frequency and available payment assistance. The default market offer is a reference price, not necessarily the cheapest option, so compare retailers and check the latest details with the retailer or the Australian Energy Regulator.
