How our tests find you the best
Overall cleaning
The best washer-dryers ensure your clothes come out spotless, so we measure stain removal on cottons and synthetics programs.
Rinsing efficiency
We measure the alkaline levels in the water after rinsing to determine how much detergent remains on your clothes.
Tumble drying
We weigh clothes before and after a cycle and check for any hidden damp spots, so you can be sure they're ready to wear.
We also test…
Ease of use, running costs, water use and more.
Every year we rigorously test washer-dryers – from ease of use to the quality of the spin-cycle – to find the best model for you. Only logged-in members can see our full list of the best washer-dryers in our table below. Join Which? to get instant access to our Best Buys and expert reviews.

We wash and dry more than 1,300kg of laundry a year in our rigorous tests so you can be sure the ones we recommend really do live up to their claims. The best washer-dryers will leave your clothes sparkling clean and fresh, while the worst will make you wish you’d never pressed start.
In order to remain impartial and unbiased, we never accept free samples or 'gifted' products and always buy them directly from retailers - exactly the same way you do. We try to emulate the day-to-day consumer experience as much as we possibly can in our tests, so we can provide you with all of the necessary information you need to make a final buying decision.
There is such a wide variety in the scores of washer-dryers in the same price bracket that it can seem impossible to work out exactly what you're paying for. You might expect more-expensive washer-dryers to perform better, but we've actually found cheaper models that score higher than their pricier counterparts, proving that money really can't buy performance.
Our washer-dryer reviews are solely based on the thorough lab testing and assessments that we carry out at Which? – nobody else goes to the lengths we do to weed out the good from the bad and everything in between.

On freestanding models, the front of the machine will always be visible and won’t be hidden away like an integrated machine.
Drum capacities vary, but an average-sized one will take around 8kg of washing and 5kg of drying.
See all our freestanding washer-dryer reviews.
The front of an integrated washer-dryer is covered with a kitchen door panel when it's installed.
Drum capacities tend to be smaller than freestanding washer-dryers. Most models have a wash capacity of around 7kg and a dry capacity of 5kg.

Vented dryers remove warm air through a hose or vent that leads out of the house, for example through a window. Washer-dryers usually don't need a vent, as the majority of models cool air inside the machine and the remaining water is drained away.
Almost all washer-dryers nowadays come with sensor-driven automatic drying programs. This means that the machine sets the drying time based on the humidity in the drum. But our tests have found that some are much more accurate at setting how long to dry than others.
We've found those that over-dry clothes, which could lead to shrinkage and fabrics becoming damaged. Others miscalculate the other way, leaving clothes too wet.

When you’re in the shop, you won’t be able to tell how noisy different models are. So, if having a quiet appliance is important, take a look at our washer-dryer reviews and sue the 'quietness' filter to see the appliances that get at least a four-star rating from us for this feature.
We include a noise star rating for all models we review. The more stars the quieter the machine will be.
Almost all washer-dryers use water when drying – they use it to cool the condenser and it's this that turns the steamy air into water, which can be drained away from the machine. An average sized one (8kg washing and 5kg drying) will use around 20,000 litres per year in total to wash and dry.
A washer-dryer can cost anything from just over £350 to around £1,000.
Our research shows that paying more doesn't necessarily mean that you'll get a more reliable machine. In fact, the brand with the lowest average spend achieved a decent 70% reliability rating.

Running costs for washer-dryers can be expensive, but opting for a more efficient machine will help save money in the long run.
Based on the energy price cap in place from April 2025, a typical 7kg washer-dryer (with 4kg drying capacity) will cost on average £161 per year to run, while a 12kg washer-dryer (8kg drying capacity) will cost on average £273 per year to run. Drying makes up the majority of these costs.
We'll give you the usage cost in each of our reviews, so you can compare the most and least expensive models.

Most washer-dryers are between 595 and 600mm wide. They are designed to fit into a space 600mm wide. The standard height of a front-loading washing dryer is 850mm high. But there can be exceptions, so check the specifications before choosing a model.
Depth can differ, though – ranging from around 40cm to 70cm. Avoid having your machine sticking out into the walkway of your kitchen by checking the specs of a model against the space you have in your home before you buy it.
Washer-dryers always have two drum capacities – one for washing and one for drying, and they can always wash a larger load than they can dry.
Think about how often you wash your clothes and the amount of garments you wash in one go. If you have lots of clothes but you only like to do two loads a week, a larger drum size will suit.
A good spin can remove the majority of water from your clothes, which reduces the amount of drying time you’ll need. We've found that higher spin speeds often do a great job of removing water from your clothes, but not every time.
Spin speeds typically go from 1,000rpm to 1,600rpm, and you may have to pay more for a model with a higher spin speed. Faster isn’t always better, though, as we’ve tested washer-dryers with 1,400rpm spin speeds that do a better job of removing moisture from clothes compared with a model with a 1,600rpm spin.
These are two machines in one so, in theory, there’s more that can go wrong with them. Choose a washer-dryer from a brand with a good reputation for product reliability and performance.
Going for a well-known name won’t guarantee you'll get a reliable washer-dryer that won’t break down, particularly where washer-dryers are concerned.
Every year, we contact thousands of members and get feedback to find out how reliable brands of washer-dryers are.

While cheaper models are always tempting, our in-depth tests show it's worth stretching your budget to around £500 for a great model that washes and dries well.
