Changing the time you wash clothes to a specific three-hour window can reduce washing machine running costs by more than half, according to energy supplier E.ON. The company identified the period between 2am and 5am as "super off-peak" hours when electricity costs drop dramatically.
Off-Peak Pricing Explained
Electricity prices vary by time of day under time-of-use tariffs, which charge more during high-demand periods like weekday evenings and less when demand is low. E.ON stated: "It turns out that timing is everything. Using your washing machine during off-peak hours could make a noticeable difference to your monthly bill."
The washing machine is one of the most energy-consuming appliances in a household, and although a single cycle may seem insignificant, costs accumulate over time. The experts noted that the "easiest ways to trim your running costs" is to wash clothes during "cheapest windows."
Prime Time for Savings
Energy experts point to a sweet spot between 10pm and 8am for cheaper rates, with some suggesting a morning window between 7am and 8am for those who prefer not to run machines overnight. However, E.ON specified that 7pm to 2am is off-peak, and the super off-peak period from 2am to 5am sees electricity costs drop by more than half.
Practical Tips for Laundry Savings
To take advantage of these cheaper hours, consumers can use their washing machine's delay start function to load clothes in the evening and set the cycle to run overnight. Grouping clothes into fewer, fuller loads instead of small daily washes also reduces energy use. Pre-soaking stained or smelly items can shorten wash times or eliminate the need for high-temperature cycles.
E.ON emphasised that planning laundry around off-peak hours is straightforward and can lead to noticeable reductions in monthly energy bills.
