How to choose the right washing machine for your needs

A is the highest rating on the energy scale the UK adopted in March 2021, which runs from A to G. It is now very common — 93% of machines on sale are A-rated — so it no longer separates efficient machines from inefficient ones on its own. Compare the kWh figure on the label instead: among A-rated machines it ranges from 17 to 54 kWh per 100 cycles.

Here's the freeing part: almost any machine will get your clothes clean — that part is genuinely hard to get wrong. So choosing well isn't about the wash. It's about everything around it — a machine that fits, stays quiet, and keeps going for years. Get that right, and you end up with the best thing an appliance can be: one you never have to think about, quietly getting on with it long after the fuss of buying it is forgotten.

Choose a washing machine in four steps. Measure the space first — standard machines are about 60cm wide and 85cm tall, but depth runs from 45cm to 70cm. Match the drum to your household: 7–8kg for one or two people, 9kg for three or four, 10kg or more for five or larger families. Compare the kWh figure, not the energy letter — 93% of machines on sale are A-rated, but among them consumption runs from 17 to 54 kWh per 100 cycles, roughly £9 to £28 a year. And choose a 1400rpm spin unless you have a reason not to.

Will it fit? Start with the space, not the spec sheet

It sounds obvious, but the most common buying mistake is falling for a machine before checking it will actually go where it needs to. Standard freestanding washing machines are almost all the same width and height — around 60cm wide and 85cm tall — which is what lets them slot under a kitchen worktop or into a fitted gap. The measurement that catches people out is depth. This varies a lot, from slim 45cm models built for tight spaces to 60–70cm for the big-drum machines, and it is the one worth measuring twice.

Three checks save almost every fitting disaster. First, measure the gap itself — width, height and depth — and leave a couple of centimetres of breathing room on each side so the machine is not wedged in. Second, remember the back of the machine needs space for the water hoses and the plug, so add roughly 5cm to the depth you actually need. Third — and this is the one people forget — check the route in. A machine that fits the gap perfectly is no use if it will not come through the front door, round a tight hallway corner or down a narrow set of stairs. Measure the narrowest point on the way in before you buy.

Freestanding or integrated?

There are two basic types. A freestanding machine stands on its own, with a visible front — this is what most people buy, and it is what almost every machine on the shop floor is. An integrated machine hides behind a matching kitchen cupboard door, so the laundry appliance disappears into a fitted kitchen. If you have a fitted kitchen and want that seamless look, integrated is worth considering; otherwise freestanding is simpler, cheaper and far easier to replace when the time comes.

One honest thing to know before you set your heart on integrated: far fewer of them are made. We do score integrated machines on WithAChoice, but because manufacturers produce so few models, the choice is genuinely limited — you may find only a handful worth recommending at your budget. Our buying guides focus on freestanding machines because that is what the large majority of people are actually shopping for, so if you want the widest choice and the best value, that is where to look. You will find our full freestanding rankings in the top 10 best washing machines guide, or broken down by budget in our best budget, mid-range and premium guides.

Drum size and household size

The most important decision in buying a washing machine is its capacity, measured by the size of its drum. Getting this wrong means either doing multiple loads every day or washing clothes in a half-empty drum and wasting energy. As a general rule of thumb: 7 to 8kg suits one or two people, 9kg works well for three or four, and 10kg or above is the right call for families of five or more, or anyone who regularly washes bedding and large items. These weights refer to the dry weight of the clothes.

A typical 8kg load consists of roughly 4 t-shirts, 2 pairs of jeans, 5 items of underwear, 4 pairs of socks, 2 hand towels, 1 jumper and 3 shirts. That comes to around 4kg dry weight, which means you can comfortably fit two people's weekly clothes in a single 8kg load. A good rule is to fill the drum to about three quarters full when loading dry clothes — this leaves enough space for the water and gives the machine room to wash effectively.

Item	Quantity	Approx dry weight
T-shirts	4	600g
Jeans	2	1,400g
Underwear	5	250g
Socks (pairs)	4	200g
Hand towels	2	600g
Jumper / sweatshirt	1	500g
Shirts	3	450g
Total		~4kg dry

A 9kg drum is the most popular family size, hitting the sweet spot for three or four people — if that sounds like your household, our best 9kg washing machines guide ranks the top options.

Energy rating

Every washing machine carries an energy label, rated A to G on the scale the UK adopted in March 2021. But the letter now tells you surprisingly little: 93% of the machines we score are A-rated. What separates them is the kWh figure printed on the same label — the electricity used across 100 eco 40-60 washes.

Among A-rated machines alone, that figure runs from 17 to 54 kWh per 100 cycles. At the July 2026 Ofgem price cap of 26.11p per kWh and 200 washes a year, that is the difference between about £9 and £28 a year in electricity. The typical A-rated machine uses around 42 kWh, costing about 11.0p a wash or £22 a year.

For comparison, the typical B-rated machine uses around 55 kWh — about £29 a year — so choosing A over B saves roughly £7 a year. The gap within the A band is larger than the gap between A and B. Read the kWh figure, not just the letter.

If running costs are your main concern, we rank the most efficient machines at every budget in our energy-efficiency guide: budget, mid-range and premium.

Spin speed

A higher spin speed extracts more water before the clothes go to dry, which cuts drying time and energy use if you use a tumble dryer. Unless you are washing delicate fabrics that need a lower speed, 1400rpm is the right choice for everyday laundry. Machines at 1200rpm are cheaper but leave clothes noticeably wetter, which costs more in tumble dryer time or means longer line drying.

Noise

Noise barely matters if your machine lives in a garage or a utility room with a door you can close. It matters enormously if it sits in an open-plan kitchen, a flat, or anywhere near where people sleep or relax. Manufacturers usually quote two noise figures, measured in decibels (dB): a quieter one for washing, typically around 50dB, and a louder one for the spin — and the spin figure is the one that counts. Spin noise generally runs from about 70dB on the quietest machines to over 80dB on the loudest. Because decibels are not a straight-line scale, a machine at 76dB sounds clearly louder than one at 72dB, not a fraction louder.

As a rule of thumb: a spin figure around 72dB or below is genuinely quiet, the low-to-mid 70s is average and fine for most homes, and anything creeping towards 80dB is noticeably loud and best kept behind a closed door. If quiet operation matters to you, look for machines with inverter or direct-drive motors, which run more smoothly and tend to post the lowest spin figures.

How long will it last? Warranty and reliability

Most washing machines are built to last between eight and twelve years, but how long yours actually lasts depends far more on the motor and build quality than on the badge. The warranty is the most honest signal a manufacturer gives you here, because a company will not promise to fix something for ten years unless it is fairly confident it will not have to. A standard warranty is often just one or two years; a five-year warranty is a good sign; and a ten-year motor warranty — common on machines with direct-drive motors — is a strong vote of confidence in the part most likely to wear out.

Read the small print, though, because not all warranties cover the same thing. Some cover parts and labour together; others cover parts for several years but labour for only one or two, which can leave you paying an engineer even while the machine is technically still under warranty. The motor is also often covered for longer than the rest of the machine, so check whether that headline ten-year figure applies to the whole appliance or just the motor.

Warranty and long-term reliability are a core part of how we score every machine — you can read exactly how in our WAC Score explainer. If reliability is your top priority, our guide to which washing machine brand is most reliable ranks the brands on the data, and our brands to reconsider guide flags the ones whose track record gives us pause.

Smart features

Wi-Fi connectivity is worth having if you run a busy household and want to start a wash remotely or get notifications when a cycle finishes. Some machines also have smart sensors that detect how soiled the clothes are and adjust the wash cycle for optimum energy use. It may be worth paying a little extra if any of these features would be genuinely useful in your circumstances.
