An energy comparison can help you check whether a different retailer, plan or tariff may better suit your household’s usage. Compare estimated annual costs, supply charges, usage rates, discounts, solar feed-in rates and any exit or late-payment fees, rather than focusing on one headline offer. In Australia, the government’s Energy Made Easy website lets you compare plans using your postcode and recent bill details. Reducing usage through efficient appliances, draught-proofing and running high-use appliances during cheaper periods may also help, depending on your tariff. Your final costs depend on your home, location and retailer’s terms.
