Check your electricity plan first, because off-peak times and rates vary between retailers, tariffs and states, and may change with daylight saving. Run flexible appliances such as dishwashers, washing machines and pool pumps during the cheaper period, using timers where appropriate. Avoid running several high-use appliances at once if your plan has demand charges, and make sure your hot-water system is set up for its controlled-load or off-peak period. Your retailer can confirm the exact times and conditions on your plan; compare the potential savings with any higher peak rates before changing your routine.
