There is no single set of off-peak hours across Australia in 2026: times depend on your state, electricity distributor, meter and tariff. Time-of-use plans commonly charge less overnight or during other low-demand periods, while controlled-load tariffs may apply separate hours to appliances such as electric hot-water systems. Check your electricity bill or ask your retailer for the exact periods, rates and daily supply charge before switching. Compare those details with your household’s usage, as the retailer’s offer and your individual consumption will determine whether you save.
