Running your washing machine between 7am and 8am is the cheapest time of day to do laundry, according to industry experts at Dr. Beckmann. This so-called 'magic hour' represents the lowest-cost point in the day to get your washing done, as most energy providers reduce their tariffs between 10pm and 8am.
However, leaving a wash running overnight is never advisable due to fire safety concerns, so early risers can take advantage of these lower off-peak prices instead. Tackling washing first thing in the morning also allows you to hang it out to dry before heading off to work or the school run, freeing up time later in the day.
Energy bills set to rise
As the cooler months approach, households are looking for ways to reduce their domestic bills. According to The Energy Saving Trust, annual energy bills for a typical dual-fuel household in Great Britain paying by direct debit will go up £60 a year. With the energy price cap sitting at £1,723, a four per cent increase from October 1 to December 31, using appliances efficiently has never been more important.
Washing machines, dishwashers and tumble dryers account for 14 per cent of a typical energy bill, making them the most power-hungry appliances in the home. The electricity required to heat the water or air within them means these machines consume considerable energy, which can be costly for the many Brits who run a wash daily.
Wash on a low heat and avoid half loads
Washing clothes at lower temperatures and for shorter cycles can significantly boost a machine's energy efficiency. A 30-degree cycle can reduce a washing machine's energy consumption by half, compared to a 40-60-degree cycle. These cooler temperatures are capable of cleaning everyday items that are not heavily soiled.
The NHS website advises that underwear, towels and household linen should be washed at 60°C to prevent the spread of germs, or at 40°C using bleach-based laundry products such as bio-based washing powder. To help keep bills down, set these items aside for a separate hot wash, and always select the ECO setting where available.
Avoiding half loads is another effective way to cut costs, as full loads are a more economical choice. If you need to run a smaller load, always use the half-load programme if your machine has one. According to laundry experts at Ariel, the 1-palm trick can help gauge the ideal load: place your hand inside the drum, and the load is right when you can fit your hand in alongside the laundry, but nothing more.
Maintain your machine and consider dryer balls
As appliances age, they can become less energy efficient. According to experts at The Energy Trust, it is essential not to overload the drum, as this could lead to damage. They also advise cleaning the machine's filter on a monthly basis and carrying out a monthly service wash — a hot cycle without any clothes. Always empty clothing pockets beforehand to prevent items from becoming lodged in the drain pump or causing damage to the drum.
For tackling stains effectively at lower temperatures, bio capsules or laundry liquid are the superior choice, as they contain enzymes that activate at lower temperatures than non-bio products. However, non-bio detergents are more suitable for sensitive skin, as they contain fewer harsh enzymes.
Dryer balls work by stopping laundry from bunching together in the dryer, tumbling between layers and keeping fabric separated. This allows warm air to flow more freely, which can cut down on drying time, while also reducing wrinkles, combating static and leaving clothes soft.
Tumble dryers are the least energy-efficient appliance in the average home. Where possible, hang clothes on the line during warmer weather if you have outdoor space. If that is not an option, position a drying rack in the warmest room in your home and close the doors.
Energy price cap changes
OfGem has shared the changes to electricity and gas prices, as well as standing charge units, for households paying by Direct Debit. From July 1 to September 30, 2026, electricity costs 26.11 pence per kWh with a 57.19 pence daily standing charge, and gas costs 7.33 pence per kWh with a 29.04 pence daily standing charge.
From October 1 to December 31, 2026, electricity will cost 26.32 pence per kWh with a 54.83 pence daily standing charge, and gas will cost 7.97 pence per kWh with a 29.68 pence daily standing charge.
