An energy comparison can help you find a plan with lower usage rates, supply charges or better discounts for your household’s needs. Compare estimated annual costs using your actual bill data, and check whether discounts are conditional, how long they last and whether rates can change. Reducing usage through efficient appliances, shorter heating and cooling periods, and better insulation can also lower bills, regardless of your retailer. Use your state or territory’s official comparison service, such as Energy Made Easy or Victorian Energy Compare, and contact retailers directly to confirm current prices and eligibility.
