How Much Electric Does a Washing Machine Use

Discover how much electric a washing machine uses in the UK, how settings affect costs, and ways to reduce energy consumption.

Washing machines are a staple of modern homes, and while they are essential for keeping clothes clean and fresh, many people want to know how much electricity they really use. With rising energy bills in the UK, understanding the power consumption of a washing machine can help households manage costs more effectively. The amount of electricity used depends on several factors, including the model, its efficiency rating, the temperature setting, and how frequently it is run.

Understanding Washing Machine Power Ratings

Every washing machine comes with a power rating, usually measured in watts. This gives an indication of how much energy the appliance draws when in operation. Most household washing machines use between 500 and 2,000 watts, although the exact figure depends on the size of the drum and the programme chosen. Short, cool washes require less energy, while high-temperature cycles or intensive washes use more electricity because the machine’s heater works harder to heat the water.

Energy Labels and Efficiency Standards in the UK

In the UK, all washing machines sold must meet minimum energy efficiency standards. The energy label provides an easy way for consumers to compare models, showing annual estimated consumption, water use, and performance ratings. An A-rated machine will typically use less electricity than a C-rated one to complete the same wash. These efficiency ratings are based on UK and EU regulations that require manufacturers to design appliances with lower running costs and reduced environmental impact. Choosing a higher-rated machine can make a noticeable difference in long-term household bills.

How Temperature Settings Affect Energy Use

One of the biggest factors in how much electricity a washing machine uses is the wash temperature. Heating water consumes far more energy than simply spinning the drum. A 60-degree wash can use nearly twice as much energy as a 30-degree wash. For most everyday laundry, a 30-degree setting is usually sufficient, helping to keep costs down without compromising on cleaning performance. Modern detergents are designed to work effectively at lower temperatures, which makes energy savings easier to achieve without affecting hygiene.

Average Costs of Running a Washing Machine in the UK

To work out the cost of running a washing machine, you can multiply its power consumption by the length of the cycle and then by your electricity tariff. As an example, a 1,000-watt machine running for one hour uses one kilowatt-hour of electricity. With average UK electricity costs around 28 pence per kilowatt-hour, this means a typical wash might cost between 15 and 40 pence, depending on the cycle and temperature chosen. Over the course of a year, with three or four washes per week, the total running cost can range from £25 to £60.

The Role of Spin Cycles and Efficiency

While the heating element is the biggest contributor to electricity use, spin cycles also play a role. A faster spin speed does not significantly increase electricity consumption during the wash itself, but it leaves clothes drier. This means less time is needed in a tumble dryer, which is often one of the highest energy users in the home. Choosing an efficient spin cycle can therefore save more energy indirectly by reducing reliance on other appliances.

Standby Power and Modern Features

Most modern washing machines are designed to use very little power when not in operation. Standby consumption is usually less than one watt, which equates to only a few pence per year. However, some smart washing machines with Wi-Fi connectivity may use slightly more electricity when idle. Turning off the machine at the wall after use can eliminate this small but constant power draw.

Water Use and Its Impact on Energy Consumption

Although water consumption is often discussed separately from electricity use, the two are linked. A machine that uses more water requires more energy to heat it during higher temperature washes. Newer machines are designed to balance water levels with the size of the load, reducing unnecessary energy use. This is another reason why modern appliances tend to be more efficient than older ones, even when run on the same settings.

Practical Tips for Reducing Washing Machine Energy Costs

There are several ways to lower the amount of electricity a washing machine uses. Running full loads instead of half loads ensures that energy is not wasted on small amounts of laundry. Choosing a lower temperature setting for everyday washing is one of the simplest ways to cut consumption. Keeping filters clean and maintaining the machine also ensures it operates efficiently. For households considering a new purchase, selecting a high-rated machine with eco wash options will reduce long-term running costs.

Final Thoughts

A washing machine is an essential household appliance, but it does contribute to electricity bills. The exact amount of electricity used depends on the model, the settings, and how often it is run. On average, households can expect to spend around £25 to £60 a year on electricity for washing, with hot washes pushing the figure higher. By choosing efficient cycles, washing at lower temperatures, and investing in an energy-rated machine, it is possible to keep costs manageable while still enjoying the convenience of clean clothes.
