Quick verdict
This is a cautious comparison shortlist, not a single universal winner, because the most sensible pick depends on household size, laundry habits and how often you can fill the drum. Start with Bosch Series 4 WAN28255GB 9kg Washing Machine with 1400 rpm at £499, Bosch Series 6 WGG244ZCGB 9kg Washing Machine with 1400 rpm at £599, and Samsung Series 5 AI Energy ecobubble™ WW80CGC04DAB 8kg Washing Machine with 1400 rpm at £399. The full shortlist sits in a £399-£599 band, so the real question is whether paying more brings a capacity or efficiency fit that suits your home better.
Top picks to compare
Start with Bosch Series 4 WAN28255GB 9kg Washing Machine with 1400 rpm (£499), Bosch Series 6 WGG244ZCGB 9kg Washing Machine with 1400 rpm (£599), Samsung Series 5 AI Energy ecobubble™ WW80CGC04DAB 8kg Washing Machine with 1400 rpm (£399) because they give you a focused set of current retailer options to compare. The visible price range is £399-£599, so check whether the extra spend buys a useful specification difference rather than only a different brand or finish. The shortlist includes Bosch, Samsung, which helps you compare familiar brands against specification, delivery and value.

What the research shows
AO’s washing-machine guidance says energy rating is a key factor, and it also notes that eco programmes usually use lower temperatures and longer cycles. That makes the energy label, load size and programme choice more useful for lower-running-cost comparisons than brand name alone. Official energy-label or product-fiche evidence is available for Bosch WGG244ZCGB and the Samsung models in the shortlist, but there is no independent lab comparison or lifetime-cost calculation here, so shoppers should treat this as a compare-and-check guide. All five picks are freestanding washing machines, which keeps the shortlist consistent and makes capacity and efficiency the main differences to weigh.
Main trade-offs to weigh
The biggest trade-off is upfront price versus the signals that point to lower running costs. The Samsung WW80CGC04DAB starts at £399, the Samsung WW90CGC04DAB is £419, the Bosch WAN28255GB is £499 and the Bosch WGG244ZCGB is £599, so you should ask what the extra spend changes in practice. Capacity matters too: 8kg may suit lighter or smaller household laundry, 9kg is the middle ground in this shortlist, and 10kg is only worth paying for if you regularly have bigger loads. Smart or AI-style features can be helpful, but they should be treated as a bonus rather than the main buying signal when your goal is lower running costs.
Why this shortlist is useful
The shortlist is narrow on purpose: five washing machines from two brands, Bosch and Samsung, all freestanding, all with visible review details and a tight 4.8 average rating across the set. That matters because it means star scores do not separate them well, so the better way to compare is by capacity, energy information and price. Bosch models show higher review volume than the Samsung models, which can add confidence in ownership feedback, but it does not prove lower running costs. In other words, this page helps you compare practical fit rather than chase the highest-rated badge.
Quick shortlist benchmark
The visible price range runs from £399 to £599, with 8kg, 9kg and 10kg capacities represented across the shortlist. The Samsung Series 5 AI Energy ecobubble™ WW80CGC04DAB 8kg model sits at the low end, while the Bosch Series 6 WGG244ZCGB 9kg model sits at the top end, with other options between them. Average customer rating is 4.8 across the shortlist, so rating alone is not a strong separator; review volume is better used as a confidence signal only. Check the latest stock, delivery and retailer terms before buying, because availability and pricing can change after the last check.
How to choose between them
Start with your household size and typical load pattern, because a larger drum only helps running costs if you regularly fill it well. For example, the Samsung Series 5 AI Energy ecobubble™ WW80CGC04DAB is an 8kg model at £399, while Bosch Series 4 WAN28255GB and Bosch Series 6 WGG244ZCGB are both 9kg freestanding machines at £499 and £599, so the price gap only makes sense if the extra capacity or feature set suits your laundry routine. Then check dimensions, installation type and any compatibility details on the retailer page, since all the shortlist models are freestanding but fit still matters in real homes. Energy rating and eco-programme information should come next: AO guidance points shoppers to energy labels, cooler washes and longer eco cycles as core running-cost considerations. Finally, use review volume as a confidence check, then verify stock, delivery and warranty differences before you decide.
Value guide
For this topic, value means the best fit for the money, not the lowest ticket price. Compare what each model adds: the Samsung WW80CGC04DAB offers the lowest starting price in the shortlist, the Samsung WW90CGC04DAB adds a 9kg drum at £419, and the Bosch 9kg models sit higher at £499 and £599, which may only be worthwhile if the brand, format or feature set suits you better. Because the shortlist is built around lower running costs, the energy label and how you plan to use the machine matter more than finish or cosmetic differences. Always check latest price, stock and delivery terms on AO before you commit.

Buying questions
How do I choose the best washing machine for lower running costs?
Start with the energy label, then match capacity to how much laundry you actually do. AO’s guidance points to energy rating and eco programmes as key checks, so a well-sized 8kg, 9kg or 10kg machine is more important than a flashy feature name.
Is the cheapest washing machine the best value?
Not always. The £399 Samsung WW80CGC04DAB may be the best starting price, but it only represents good value if 8kg suits your household and the retailer page still shows the delivery, stock and specification you need.
Does a bigger drum mean lower running costs?
Only if you can fill it regularly. A 10kg machine such as Samsung WW10FG5U34ABEU can reduce the number of loads for larger households, but an oversized drum can waste value if your typical washes are small or only partially loaded.
How important is the energy rating versus star reviews?
For this guide, the energy rating matters more. All five shortlisted models sit at 4.8 average customer rating, so reviews are useful as a confidence check, but they do not separate the machines on running-cost potential.
Should I choose 8kg, 9kg or 10kg capacity?
Choose 8kg for lighter or smaller household laundry, 9kg as the middle-ground option, and 10kg if you regularly wash bigger loads. The shortlist spans all three sizes, so capacity is one of the clearest ways to narrow the choice.
