Start by checking the billing period, whether the meter reading is estimated, and your electricity usage compared with the previous bill. Changes in weather, heating or cooling, new appliances, tariff rates, daily supply charges and solar feed-in credits can all affect the total. If the reading appears incorrect, contact your retailer and provide a current meter reading or photo if requested. You can also ask the retailer about payment plans, concessions or hardship support, with eligibility decided under its rules and any applicable government requirements.
