Start by finding your recent bill and comparing plans using your actual electricity or gas usage, rather than relying only on advertised estimates. Check the usage rates, daily supply charge, tariffs, discounts, contract terms, fees and whether prices can change. In many parts of Australia, the government’s Energy Made Easy website can compare electricity and gas offers; Victorian households can use Victorian Energy Compare instead. The cheapest-looking plan may not suit every household, so confirm the retailer’s details and eligibility requirements before switching.
