An electricity usage checklist can cover your meter readings, billing period, tariff type and the appliances using the most power. Check heating and cooling settings, hot-water systems, pool pumps, fridges, dryers and standby devices, as these can have a noticeable effect on consumption. Look for draughts, compare your usage across bills and consider whether a retailer plan or controlled-load tariff still suits your household. Your retailer can explain billing details, while energy.gov.au provides independent energy-saving guidance.
