UK households are being urged to rethink everyday washing habits after new guidance linked to rising energy costs put washing machines firmly in the spotlight. With electricity prices still a major concern for millions, even small changes in how laundry is done could make a noticeable difference to monthly bills.
The warning comes as British Gas and other energy experts highlight how common washing routines — particularly temperature settings and load sizes — can quietly drive up household energy use without people realising.
One of the biggest issues flagged is the continued use of higher-temperature wash cycles for everyday clothing. While hot washes have long been associated with cleanliness, modern detergents are designed to work effectively at much lower temperatures, meaning hotter settings often consume more electricity than necessary.
According to energy specialists, washing clothes at lower temperatures can significantly reduce the amount of power used per cycle. Heating water accounts for the largest share of a washing machine’s energy draw, so reducing that demand can translate into measurable savings over time — especially in homes where laundry is done several times a week.
Why temperature matters
Lower-temperature washes reduce electricity use, place less strain on appliances, and are gentler on fabrics — extending the life of clothes while helping households keep costs down.
Another common habit under scrutiny is running the washing machine with small or half-empty loads. While it may feel convenient to wash a few items quickly, energy experts warn that this approach can be inefficient. The machine still uses nearly the same amount of power regardless of how full the drum is, meaning smaller loads often cost more per item cleaned.
Instead, households are encouraged to wait until they have a full load wherever possible. This improves efficiency, reduces the number of cycles needed each week, and helps lower overall electricity consumption without changing how often clothes are worn.
Eco settings, which many people overlook, are another key focus of the advice. Although these cycles sometimes run longer, they typically use less energy by heating water more gradually and operating at lower temperatures. Over time, this can result in lower running costs compared with standard quick-wash programmes.
Timing also plays a role. For households on time-of-use tariffs, running appliances during off-peak hours can further reduce costs. While not everyone has access to these plans, energy providers continue to promote flexible usage as a way to ease pressure on both household budgets and the wider electricity network.
Consumer groups say these small behavioural changes are gaining attention now because they offer practical ways for households to respond to ongoing cost pressures without sacrificing comfort. Unlike major home upgrades, adjusting washing habits requires no upfront spending — just awareness.
Official energy-saving guidance published by the UK government echoes similar advice, encouraging residents to use appliances efficiently and avoid unnecessary energy use wherever possible.

As energy bills remain under scrutiny, experts say awareness is key. By rethinking how washing machines are used — from temperature choices to load size — households may find that meaningful savings come not from drastic changes, but from smarter everyday decisions.
