How much does a washing machine cost to run?
Working out which is the best value washing machine is more than just about the ticket price.
Washing machine running costs can vary from under £20 to more than £100 per year. On average, a washing machine will add £34 per year to your bills.
Running costs are largely influenced by drum size. Some of the most efficient machines we’ve tested do a bad job of cleaning.
Energy ratings on washing machines are meant to help you choose a more energy-efficient model. They go from A+++ (the most efficient) to A on new models. The energy rating is calculated mostly on the 60°C cotton program.
When we test washing machines, we measure how much energy and water they use based on the 40°C cotton program, as this is the most commonly used wash program by Which? members, so we can give a more realistic indication of energy use.
Can you buy a sustainable washing machine?
A lot of a washing machine's environmental impact will come from using it, day-in and day-out. When replacing a faulty model, buying one that is efficient is a great way of reducing your environmental impact, and saving you money along the way.
Unfortunately, our testing shows those that use the least energy and water often fail to clean well.
That's why we've started recommending Eco Buy washing machines. These models are ones that we've carefully chosen as balancing good cleaning performance with energy and water efficiency.
Washing machine drum sizes: 5kg - 12kg
Washing machine drum sizes range from 5kg to 12kg. The most popular drum sizes are 9kg and 10kg washing machines.
Drum size is based on the number of kilos of dry clothing you can fit into the drum.
However the number quoted usually only refers to the main cotton programs – other programs have smaller capacities – sometimes less than half.
You'll find details of the difference in capacities between the cottons and synthetics programs in the tech spec section of each of our washing machine reviews.
Most medium-sized households in the UK will find a 7kg capacity machine perfectly adequate. Swipe our graphic below to see what you can fit in each different drum size.
Five things to remember on drum size
- Bigger isn't always better.
- Buy a washing machine with a drum you won’t struggle to fill.
- Washing machines work best when you fill the drum to each program’s set limit.
- The bigger the capacity, the more the washing machine will cost to buy and run.
- Prefer to wash little and often? Go for a smaller drum size. Like to do all your washing in one go? Go for a bigger drum size.

What is the standard size of a washing machine?
The standard dimensions of a front-loading washing machine are 85cm high, and 59.5cm to 60cm wide. They are designed to fit into a space 60cm wide.
But there can be exceptions, so check the specifications before choosing a model.
Washing machine measurements to check before you install
The depth of a washing machine can vary quite a bit, ranging from 40cm to 70cm.
Check to make sure you don't end up with a machine that leaves no space to walk down your galley kitchen or sticks out from underneath work surfaces.
Use our washing machine measurements table below as a guide but always measure before you buy.

Three things to note when measuring a washing machine
- Depth measurements might/might not include pipe and hoses. Be sure to check.
- Bulky door surrounds, buttons/controls that stick out and curved front casing are generally not included in dimension figures.
- Allow for around 70mm on top of the depth of your machine to make sure that you can safely accommodate your waste pipe and water inlet pipes.
Washing machine spin speeds
The spin cycle removes water from your clothes at the end of the wash program. Here's how to find the best spinner for your needs:
- Maximum spin speeds vary from 1,000rpm to 1,800rpm
- Washing machine spin speeds of 1200rpm and 1400rpm are the most common
- Faster spin speeds can add to the cost of the machine
- A faster spin speed can be noisier
- It’s not always worth paying more for a higher spin speed.
A machine with a good spin should remove the majority of water from your laundry, reducing how long your clothes will need to spend tumbling in a dryer or hanging out on a washing line.
Our washing machine tests have found you can’t always trust that a washing machine advertised with a high spin speed will actually be any better at spinning than a slower one.
And some fast machines don’t spin at their top speeds for as long as slower models.
