What is WAC Score?
Our independent rating system for washing machines — what it measures, why price bands matter, and how to use it to make a better buying decision.
Buying a washing machine should not be this hard. But most people find it is. You start with a budget and a vague idea of what you need. Within twenty minutes you have twelve tabs open, three conflicting "best buy" lists, a spreadsheet you half-built and then abandoned, and less confidence than when you started. The problem is not a lack of information. It is too much of it, presented in a way that forces you to become an expert before you can make a decision.
That is the problem WithAChoice was built to solve. WAC Score is the tool at the centre of it — an independent rating system that takes every major washing machine available in the UK, scores it across the four things that actually matter when you own one, and gives you a single number you can use to compare machines clearly. No rabbit holes. No conflicting reviews. No expertise required.
No brand pays to be included. No machine is promoted. WAC Score is calculated independently, and affiliate relationships with retailers have no bearing on how any machine scores. The score is the score.
What WAC Score measures
Every washing machine in our database is scored across four components. Each one captures a different dimension of what it is like to live with the machine — not just on the day you buy it, but over years of use.
Reliability
How likely is this machine to keep working without problems? Reliability draws on verified customer reviews — not just the average rating a machine earns, but how many owners stand behind it. A four-star rating from three thousand buyers is stronger evidence than the same rating from thirty, and we weight it accordingly. Alongside the review signal we factor in motor type and warranty length. It is the component most buyers care about most — and the one where brand reputation diverges most sharply from the actual data.
Efficiency
How much does this machine cost to run? We score the measured figure — kilowatt-hours per 100 wash cycles — not the energy letter. The letter has stopped telling you anything: 97% of the machines we score are rated 'A', and inside that single letter consumption ranges from 17 to 70 kWh, a difference of roughly £22 a year on your electricity bill. We also score spin performance class, which determines how wet clothes are when the cycle ends, and therefore how long and how expensively a tumble dryer has to run. Where a machine has no measured reading published, the letter is used as a fallback and scored below the measured median — an unknown is not treated as a strength.
Features
What can this machine actually do? Features scores reflect the range and usefulness of wash programmes, smart connectivity, drum capacity relative to price, and other practical capabilities. A machine with a high features score gives you more flexibility in how you use it day to day.
Value
How much are you getting for what you spend? Value is assessed relative to the price band — a budget machine is not expected to compete with a premium one on raw performance, but it should deliver competitive reliability and efficiency for what it costs. The value score identifies machines that over-deliver for their price, and those that charge a premium without justification.
These components are combined into a single WAC Score, which in practice runs from 55 to 92. Every machine carries one of three labels, and those labels mean exactly this:
Roughly one machine in seven is Outstanding, six in ten are Highly Recommended, and the rest are Good Value. There is no band below Good Value, and we would rather say why than let you assume it means something it does not — see below.
The four sub-scores matter as much as the overall number. A machine with a WAC Score of 80 driven mostly by efficiency but with a reliability score of 65 is a very different proposition from one that scores 80 across all four components evenly. Always look at the breakdown.
Why we compare within price bands
A £249 Beko and a £1,299 Miele are both washing machines. Comparing them directly on a single score would tell you very little that is useful — of course a £1,299 machine performs differently from a £249 one in certain respects. The question that actually matters for a buyer is: given the amount I am prepared to spend, which machine gives me the most?
WAC Score is normalised within three price bands:
- Budget — under £400 — the largest and most competitive part of the market
- Mid-range — £400 to £649 — where the most significant performance improvements over budget tend to appear
- Premium — £650 and above — where brand reputation and actual data diverge most sharply
This means a WAC Score of 88 in the budget band and a WAC Score of 88 in the mid-range band both represent an excellent machine — one of the strongest options available at that price. It also means that a premium-brand machine scoring 72 in the mid-range band is telling you something important: you are paying a premium that is not reflected in performance.
The most important finding in the data
Across all three price bands, brand reputation and actual performance frequently diverge — but not evenly, and the pattern is more useful than a blanket "premium is overrated". In the mid-range band, where the sharpest divergence sits, it is a mainstream brand that leads: Haier tops the tier, with LG just behind. In budget, Hisense leads, with Hoover and Haier close behind. And at the premium end, LG and Samsung sit level at the top — LG fractionally ahead, but the two are effectively inseparable on the data.
The clearest finding is about price rather than badge. The traditional premium marques — the names most associated with heritage engineering — fall furthest behind the mainstream in the mid-range band specifically. That is the band where a buyer pays a premium-brand price for a machine competing against mainstream models that simply do more for the money. In the premium band proper, the picture is genuinely mixed: some heritage names hold up well, others do not.
A lower score here does not mean a worse machine. Because WAC Score is normalised within price bands, a heritage brand scoring below the mainstream is telling you it is not the strongest value at that price — not that it is poorly made. These brands' case rests partly on things WAC Score deliberately does not fully capture: 20-year build longevity, parts availability and service networks (see "What WAC Score doesn't capture" below). If those matter more to you than getting the most performance per pound, the score is not the whole story.
What the data does consistently reward is measured engineering over inherited reputation. The brand with the strongest range in a band is often not the one with the strongest showroom presence.
What the score is relative to
This is the part most rating systems do not tell you, so we will.
A WAC Score is not an absolute measurement of quality. It is a machine's position relative to the other machines at its price, on a scale pinned between 55 and 92. That has three consequences you should know about before you read another number on this site.
The best machine in every price band scores 92 — always, by construction. Not because it is the best washing machine ever made, but because something has to be the best of what is for sale at that price. A 92 in the budget band means "nothing under £400 beats this right now". It does not mean "this is a 92 out of 100 machine".
An Outstanding budget machine can be mechanically inferior to a Good Value premium one. A £289 machine scoring 92 and a £1,099 machine scoring 68 are not being compared with each other, and the higher number is not telling you the cheaper machine is better made. It is telling you the cheap machine is exceptional for £289 and the expensive one is unremarkable for £1,099. If you have £1,099 to spend, the premium machine is very probably the better machine. The score is answering "what is the most I can get for my budget" — which is the question we think most people are actually asking, but it is not the only question.
A machine's score can change even though nothing about the machine changed. If a better machine launches in its price band, everything below it shifts down. That is not a glitch; it is what "best for your money right now" means. It also means a score is a snapshot of a market, not a permanent property of a product.
Nothing on this site is labelled "not recommended". The lowest label is Good Value, and that is a real limitation of how the scale is built rather than a claim that every washing machine is good. If a machine is weak, the honest signal is a score in the 50s or low 60s sitting next to a rival at 85 in the same band — not a warning label. Read the number, not just the badge.
How to use WAC Score
WAC Score is designed to narrow down your options quickly — not to make the decision for you. Here is how to get the most from it.
Start with your price band
Decide roughly what you are prepared to spend before you look at scores. The budget, mid-range and premium bands each have their own rankings. Looking at the mid-range table when you are working with a budget of £300 will not give you useful information.
Use the overall score as a shortlist tool
Any machine scoring 85 or above in its price band is an excellent choice on the data. That narrows the field significantly. From there, the sub-scores help you match the machine to your priorities — if reliability is your primary concern, weight the reliability sub-score more heavily. If running costs matter, focus on efficiency.
Always check the specific machine, not just the brand
Brand averages in our guides are a useful starting point, but a brand with a strong average can still have individual models that score significantly lower. Before buying, check the specific model's WAC Score in our browse tool. A good brand with a weak model is still a weak model.
Use it alongside your own priorities
WAC Score tells you what the data says. It does not know that you need a 12kg drum, or that your kitchen alcove is 58cm wide, or that you want a machine with a 20-minute quick wash. Use the score to identify the strongest candidates in your price band, then filter by the practical requirements that are specific to your household.
The right way to use WAC Score
- Choose your price band first
- Use the overall score to shortlist — aim for 85+ where possible
- Check the sub-scores to match strengths to your priorities
- Verify the specific model's score before buying, not just the brand average
- Use it as one input alongside your practical requirements
What WAC Score doesn't capture
A good rating system should be honest about its limits. WAC Score is built on the best data available — but there are dimensions of washing machine quality that it does not fully reflect.
Very long-term build longevity
Some brands — most notably Miele — engineer their machines to last 20 years, with a parts availability and service infrastructure to match. WAC Score's reliability component draws on customer review data and verified technical factors, but it does not fully capture the difference between a machine built to last a decade and one built to last two. If you are buying a machine you intend to keep for 20 years and want full serviceability throughout, the case for certain premium brands is stronger than the WAC Score alone suggests.
Individual model variation within a brand
When we publish brand-level averages in our guides, those averages can mask meaningful variation within a brand's range. A brand averaging WAC 80 may have models ranging from 74 to 91. The brand average is a useful signal — but the individual machine's score is always the number to rely on.
New models not yet in the database
Our database covers every major freestanding washing machine available in the UK at the time of scoring. Models launched after our most recent data update will not yet have a WAC Score. If you are considering a very recently released machine, it may not appear in our rankings yet.
Personal preference
WAC Score does not know how you do your laundry. It does not account for whether you prefer a certain door hinge style, a particular control layout, or a specific brand's app. The score tells you what the data says about performance — it is one input into a decision that is ultimately yours to make.
The score is a tool, not a verdict. WAC Score gives you the clearest independent view of washing machine performance available. What it cannot do is replace the practical filtering you need to do for your own household. Use both.
Frequently asked questions
What is WAC Score?
WAC Score is WithAChoice's independent rating system for washing machines. Every machine is scored across four components — reliability, efficiency, features and value — and given a single number between 0 and 100. It lets you compare machines on what they actually deliver, not on brand name or price tag. The score is calculated from real customer review data, verified energy ratings and independent spec analysis.
Is WAC Score independent?
Yes. No brand pays to be included, and no brand can influence its score. WAC Score is calculated independently, and our affiliate relationships with retailers have no bearing on how any machine or brand scores. A machine available at a retailer we work with scores exactly the same as one that is not.
How many machines and reviews does WAC Score cover?
Our current database covers 428 scored washing machines across all major UK retailers. The reliability component draws on over 370,000 verified customer reviews — giving the score a statistical base that reflects real ownership experience at scale, not a small sample of editorial opinions.
Why do you compare machines within price bands rather than overall?
Because a £249 machine and a £1,299 machine are solving different problems for different buyers. An overall ranking without price context would not tell you which machine gives you the most for what you are actually prepared to spend. WAC Score is normalised within three bands — budget (under £400), mid-range (£400–£649) and premium (£650+) — so scores are always meaningful relative to the price you are considering.
What does WAC Score not measure?
WAC Score does not fully capture very long-term build longevity — the 20-year engineering case that some premium brands make. It also reflects the database at the time of scoring, so very recently launched models may not yet be included. Brand averages in our guides can hide individual model variation, so always check the specific machine's WAC Score rather than relying on the brand average alone.
Does a higher WAC Score always mean a better machine?
No — and this is the most important thing to understand about the score. WAC Score is normalised within price bands, so it measures how good a machine is for what it costs, not how good it is in absolute terms. A budget machine scoring 90 is exceptional for its price; a premium machine scoring 70 is unremarkable for its price. The premium machine may still be the better built machine. Compare scores within a price band, not across them.
Where can I see WAC Scores for specific machines?
You can browse all scored machines by price band and capacity in our washing machine guide, or use the questionnaire to get matched to the best machines for your household. Every machine in our database shows its overall WAC Score and all four sub-scores.
WAC Score as an editorial rating
WAC Score is WithAChoice's independent editorial rating — applied consistently to every machine in our database using the same four-dimension framework. It is not a crowd-sourced average or a sponsored ranking. Every score is calculated from the same inputs: verified customer review data, published energy figures, manufacturer specifications, and price band context.
This consistency is what makes WAC Score meaningful as a reference point. Whether you are comparing a £249 budget machine or a £1,200 Miele, the same framework applies. The output — a score that in practice ranges from 55 to 92 — reflects where each machine sits relative to the other machines at its price and placement, not relative to an arbitrary benchmark, and not relative to the market as a whole.
As our database grows and our methodology matures, we intend WAC Score to become a citable reference for UK washing machine buyers, journalists and comparison services — a score you can rely on because it is produced the same way, every time, for every machine.
