Best energy-efficient washing machines UK 2026 — mid-range
The most energy-efficient washing machines between £400 and £649 — ranked by kWh per 100 cycles. Five brands, five different use cases, one clear metric. Running costs at the July 2026 Ofgem rate of 26.11p per kWh.
In short: the most energy-efficient mid-range washing machine is the Hotpoint Fabic Care Pro HPA 105 CARE UK at £519 — 25 kWh per 100 cycles, about 6.5p a wash. But it is the value paradox in one machine: it wins on running cost while scoring only 64 on the WAC Score. For a few more kWh, the LG F4X7009TBB (£529) scores 81 — the efficient buy most people should actually make.
The same trap that catches every efficiency ranking is at its sharpest in the mid-range, where you are spending enough that the machine ought to be good at more than one thing. Sort a list by kilowatt-hours alone and the winner is whichever machine shaves off the last unit of electricity — even if it is dearer, plainer and worse value than the machines just behind it. The cheapest machine to run is not automatically the machine worth running.
So read the top of the table for the lowest kWh, but read the WAC Score column for which machine is actually worth £400–650 of your money once reliability, features and value are weighed alongside efficiency. Where the two disagree — and here they disagree sharply — trust the WAC Score. The genuinely efficient and sensible machines sit a rung down, and we point straight at them.
Every machine here is A-rated, freestanding and priced £400–650, with kWh and cost-per-wash figured at the July 2026 Ofgem rate of 26.11p per kWh. We cap each brand at two.
Running cost formula: kWh per 100 cycles × 26.11p ÷ 100 = cost per wash. At 5 loads per week, multiply by 260 for the annual figure.

Our top picks in detail
Hotpoint Fabic Care Pro HPA 105 CARE UK
10.0kg · 1400rpm · A rated · White
The most efficient machine in the mid-range band — 25 kWh per 100 cycles, about 6.5p a wash — and the guide’s cautionary tale. Its WAC Score of 64 is the lowest of the five, held down by a weak value score: you are paying mid-range money for a machine that is efficient and little else. It wins the kWh column, not the kitchen. Most people should read on.
LG F4X7009TBB
9.0kg · 1400rpm · A rated · Black
The one to actually buy. At £529 the LG gives up only a few kWh to the leader (29 kWh, 7.6p a wash) while posting the highest WAC Score of the group at 81. Efficiency wins the ranking above; this wins the kitchen — the best all-round machine that is still genuinely economical to run.
Haier X5 Plus HW100BP14357AEUK
10.0kg · 1400rpm · A rated · White
Efficient value. WAC Score 74 at £429, running at 31 kWh (8.1p a wash) — a keenly-priced way into a low running cost without giving up much elsewhere. A sensible middle option.
Hoover Pro Wash Series 7 HBQD 410BL10U-80
10.0kg · 1400rpm · A rated · White
Efficient, if plainer. WAC Score 69 at £449 and 31 kWh — the running cost is there, but the overall package trails the machines above it. Worth it mainly if the price is right on the day.
Hisense 5i KitchenFit Series WF5I1045BWQ
10.5kg · 1400rpm · A rated · White
Efficient and well-equipped. WAC Score 76 at £549, 31 kWh a run, with a strong features set for a Hisense — the pick if you want low running costs without stripping back the spec.
The bottom line
The whole guide in one line: the Hotpoint Fabic Care Pro HPA 105 CARE UK wins the kilowatt-hour column, the LG F4X7009TBB wins your money. The difference in running cost between them is a few pounds a year; the difference in what they are like to own is far wider. Buy on the WAC Score and treat efficiency as the tie-breaker it is. For the full mid-range picture, our best mid-range guide ranks the same band on overall value.
Frequently asked questions
What is the most energy-efficient mid-range washing machine?
The Hotpoint Fabic Care Pro HPA 105 CARE UK is the most efficient in the £400–650 band in our current data, at 25 kWh per 100 cycles (about 6.5p a wash) for £519. But it uses only marginally less electricity than the machines behind it while scoring lower overall, so its WAC Score is 64. For the best balance of efficiency and value we would point most buyers at the LG F4X7009TBB (WAC Score 81).
How much does energy efficiency actually save in the mid-range?
Less than the price gap usually justifies. At the July 2026 Ofgem rate of 26.11p per kWh, the spread between the most and least efficient machine in this guide is only a few kilowatt-hours per 100 cycles — a few pounds a year for a typical household. Buy price and overall quality almost always matter more than the last kilowatt-hour.
What does kWh per 100 cycles mean?
It is the energy label's standard measure: the electricity a machine uses across 100 wash cycles on the standard eco 40–60 programme, in kilowatt-hours. Lower is better. Multiply by your electricity rate (26.11p per kWh as of July 2026) and divide by 100 for the cost per wash.
Is an A-rated machine always cheaper to run?
Not necessarily cheaper than every other A-rated machine — the A grade is a band, and machines within it still vary by a few kWh. It will be meaningfully cheaper than an older B- or C-rated machine. Every machine in this guide is A-rated under the current label.
Are these washing machines freestanding?
Yes — every machine here is freestanding, a standalone unit you can plumb in anywhere. We do not include integrated (built-in) machines, which need a fitted kitchen cabinet and a cupboard door and are a separate category.

Answer a few questions and we will match you to the best washing machine for your household — across all budgets, all brands.
