Run flexible appliances such as washing machines, dishwashers, pool pumps and electric vehicle chargers during your retailer’s off-peak or shoulder periods. Check your bill or ask your retailer when these times apply, as they vary by tariff, meter and location and may not include weekends. Compare the off-peak rate with the daily supply charge and peak rate before changing plans, because a cheaper overnight rate may not reduce your total bill if most usage remains during peak hours. Your retailer can confirm whether you have a controlled-load tariff or smart meter, while Energy.gov.au provides general guidance on comparing energy plans.
