A higher electricity bill can result from increased usage, seasonal heating or cooling, tariff changes, a price update, or an estimated meter reading. Check the bill’s billing dates, meter reading type, daily usage, supply charge and cents-per-kilowatt-hour rate, then compare these with an earlier bill. If the reading is estimated or something looks incorrect, contact your retailer and provide a current meter reading or request an investigation. You can also compare electricity plans through the government-run Energy Made Easy service.
