Is a premium washing machine worth the money?
We scored 7 Miele, 17 AEG, 6 Siemens and 7 Bosch washing machines using the WAC Score — the same data-driven framework applied to all 500+ machines in our database. Here is what spending £900 to £1,700 actually buys you.
The question comes up constantly: is Miele actually better? Is AEG worth the extra £300 over LG? Does spending £1,200 on a Siemens buy you a meaningfully superior washing machine?
Most buying guides sidestep this question. They list the features, note that Miele has a 20-year design life claim, and leave the conclusion to you. We have taken a different approach. We scored every prestige brand machine in our 500+ machine database using the same four-dimension WAC Score framework applied to every other machine — reliability, efficiency, features and value. The results are not what most people expect.
A premium price does not guarantee premium performance. The highest-scoring machines on our site come from LG, Haier and Hisense between roughly £299 and £769 — not from the £1,000-plus luxury names. Miele, AEG and Siemens charge the most but average 70, 73 and 64 on the WAC Score — mid-pack. Premium is worth paying for when the engineering earns it, and often that is a well-made mainstream machine rather than a luxury badge.
How we scored these machines
The WAC Score combines four sub-scores into a single number between 55 and 92 within each price band. The four dimensions are:
- Reliability score — derived from verified customer review data weighted by statistical confidence. Larger review samples produce more reliable scores.
- Efficiency score — based on kWh per 100 cycles (energy label data), water consumption per cycle and energy rating.
- Features score — programme count and specialist features including steam, auto-dosing, Wi-Fi, allergen cycles and sensor wash.
- Value score — how the machine's overall specification compares to its price within the premium tier.
Scores are normalised within the premium price band (£650+). A score of 80 here means the machine sits in the upper half of the premium tier — it does not mean 80 out of 100 in an absolute sense.
What this analysis cannot measure: WAC Score is a point-in-time measure based on current data. It does not directly measure long-term machine lifespan, repairability, or parts availability over a 15–20 year ownership period. Where these factors are relevant — particularly for Miele — we note them clearly.
The summary: brand by brand
| Brand | Models scored | Price range | Avg WAC Score | Top WAC Score |
|---|---|---|---|---|
| LG | 16 | £348–799 | 84 | 92 |
| Samsung | 12 | £379–999 | 78 | 86 |
| AEG | 17 | £379–1049 | 73 | 89 |
| Miele | 7 | £849–1699 | 70 | 82 |
| Bosch | 7 | £449–899 | 66 | 72 |
| Siemens | 6 | £749–1099 | 64 | 77 |
The headline finding: LG and Samsung lead the premium tier on average WAC Score, with top scores of 92 and 90 respectively — and both now span a wide price range starting well below £650. Miele, AEG, Siemens and Bosch — the brands most associated with premium washing machines — score lower on average, at higher minimum prices. One important note: LG and Samsung's wide price ranges (starting from £349) mean their averages include many mid-range machines. The comparison that matters for this guide is the premium tier specifically, where LG's best machines score 92 at £699 and Samsung's score 90 at £449.
Miele
Miele
Miele’s best machine scores 82, and the range runs to £1,699. The premium here buys longevity — Miele’s reputation is machines built to last twenty years — not a higher WAC Score, which at an average of 71 trails mainstream LG. Worth it if you keep appliances for a generation; less so if you compare on current spec and price.
AEG
AEG
AEG is the most interesting case. Its top machine scores 89 — genuinely excellent — and its premium 7000 and 9000 flagships are worth the money. But its average WAC of 71 is dragged down by weak mid-range value, so where AEG sits in its range matters enormously: premium, yes; mid-range, no.
Bosch
Bosch
Bosch’s highest score (72) is modest, and it rests on reliability rather than features or value. It is a dependable brand (reliability 82) but poor value (31): at premium prices you are paying for the badge and the build quality, not a better score.
Siemens
Siemens
Siemens is the weakest case on the page. Its top WAC Score is just 78, on the lowest value score here (32) and below-average reliability (73), at prices from £699. Little in the data justifies the premium over a higher-scoring rival.
The verdict: when does premium price actually buy something?
✓ Premium performance is justified — LG from £499 and Samsung from £449
Premium is worth it when it buys something real — AEG’s 7000 and 9000 flagships (top score 89), or Miele’s two-decade lifespan. It is not worth it when it only buys a badge, as with Bosch and Siemens. And the headline of the data is blunt: mainstream LG (average WAC 81) and Samsung (76) out-score every dedicated premium brand here. A high price is no guarantee of a high score — buy the machine, not the marque.
~ Conditional — Miele at £849–899 and Bosch’s premium line
Miele at £849–899 is justified if machine longevity over a 15–20 year period is your primary consideration — a real benefit our review-based score cannot measure. Bosch’s premium range is worth it for reliability and quietness, though its best value is actually its £449 mid-range machine. In both cases you are buying something specific, not a higher score.
✗ Premium price is not supported by the data — AEG above £721, Siemens, Miele above £999
AEG’s top WAC Score is reached at £721; spending more within its range (to £1099) does not buy a better machine. Siemens posts the lowest value score of any premium brand (28), and Miele above £999 buys longevity rather than measured performance. At these prices the money works harder with LG, Samsung or Haier.
Frequently asked questions
Does Miele actually last longer?
Miele state their machines are designed for 20 years of use, or around 10,000 running hours — well beyond the industry norm. That longevity is real and is Miele’s core premium, but it is the one thing our WAC Score cannot verify: the score is built from verified owner reviews, which capture the first years of ownership, not two decades. So Miele can score mid-pack on measured performance while still being the right choice for a buyer optimising for a very long lifespan.
Why does AEG score lower on features than LG or Hisense?
AEG’s best features score is 85, competitive but not class-leading. LG and Hisense pack more into their machines at the price — steam, smart programmes, connectivity — and it shows in higher features and overall scores. AEG competes more on build and brand than on specification.
Is Bosch better than Siemens?
On our data, clearly yes. Bosch averages a WAC Score of 71 with a best reliability of 90, against Siemens’ 63 average and much weaker value (28). The two share engineering heritage, but Bosch delivers meaningfully more for the money across the range.
Should I buy LG instead of Miele?
On measured performance and value, yes — LG’s best scores 92 for as little as £499, against Miele’s top of 85 at £899. The exception is longevity: if you intend to keep a machine for 15–20 years, Miele’s build is designed for it in a way LG does not claim. For most buyers over a normal ownership period, LG is the better value.
What does the WAC Score not measure about these machines?
It does not measure the things premium brands trade on hardest: lifespan beyond the review window, running noise, the feel of the build and controls, and resale value. Our score captures reliability, efficiency, features and value from verified data — an excellent guide to what a machine delivers day to day, but not a full account of a twenty-year relationship with an appliance. Where a premium brand’s case rests on those intangibles, we say so.
