Start by checking your latest bill for your usage, tariff, supply address and NMI or MIRN, then compare offers through Energy Made Easy or Victorian Energy Compare, depending on where you live. Look beyond headline discounts and check the estimated annual cost, rates, daily supply charge, contract terms, exit fees and whether your concession or solar feed-in arrangements will continue. Once you accept an offer, the new retailer generally arranges the transfer, so you usually do not need to contact your current provider. Confirm the final bill, meter details and switching date with the new retailer, as availability and costs depend on your circumstances.
