Best energy-efficient dishwashers from Bosch, Beko, Miele and more
Keen to control your energy bills? Here are the best energy-efficient dishwashers for 2025, each with a range of programmes to help save time and energy.
By Lucy Cotterill | Last updated Aug 19, 2025
With less time spent at the kitchen sink, investing in a dishwasher for your home certainly uses less personal energy, but the cost of their electricity and water usage may have been enough to put you off.
The good news is that the best dishwashers are far more energy efficient than they used to be, securing impressive A to C energy ratings without sacrificing on performance. With eco programmes and automatic cycles that tailor the wash to how dirty the contents are, many dishwashers have time and energy-saving programmes that use low levels of water and energy.
To help find the best energy-efficient dishwasher for your home, we’ve sought out tried-and-tested reviews from Mumsnet users, gathering their feedback on the best freestanding and integrated dishwasher brands for efficiency that they’ve used in their own homes and would happily recommend to others.
By combining this research with wider consumer feedback on retailer sites and the views of consumer champions, we’ve rounded up the most energy-efficient dishwashers you can buy today, all of which include several features to reduce their overall water and energy consumption.

What Mumsnet users say
While it doesn’t come cheap, this Quiet Mark accredited A-rated Bosch Series 6 dishwasher is one of the most efficient full-sized dishwashers you can buy today. A spacious design with a top-level VarioDrawer for cutlery and smaller utensils, this Bosch freestanding dishwasher can easily accommodate up to 14 place settings. We love the height adjustable shelves that help you fit larger pots and pans, and the flexible racking maximises space so you can run your appliance less regularly.
In addition to a 50-degree eco setting, the ‘auto’ programme on the Bosch Series 6 SMS6TCi00E automatically adjusts the water temperature and rinse time to suit your contents, reducing the wash duration for lightly soiled plates or turning up the heat to lift more stubborn dried-on food residue.
With a high-efficiency pump, fast heating and targeted water distribution, the ActiveWater technology ensures your plates come out sparkling clean every time. Innovative Zeolith technology also uses minerals to absorb moisture and produce exceptional drying results, so you won't need to run an additional drying cycle or give your pots a once-over with a tea towel.

What Mumsnet users say
Beko dishwashers are a top pick amongst Mumsnet users, praised for their impressive performance and budget-friendly price tag. The Beko BDFN26640W dishwasher is no exception, with low water and energy consumption combined with an affordable price that won’t break the bank.
With a respectable C efficiency rating, this Beko has several energy-saving programmes including an eco cycle and auto mode, the latter of which automatically tailors the cycle length, energy and water consumption based on how dirty your contents are.
We love the 30-minute quick wash for those days when you're pressed for time, while the Hygiene Intense programme removes 99% of bacteria - great for peace of mind. The door even opens automatically at the end of the cycle, so you won’t find a build-up of condensation on your best Tupperware containers.
It is worth noting, however, that while this dishwasher does have folding plate supports to maximise space, some reviewers found they struggled to fit larger plates and bowls in the bottom shelf.

If you’re seeking value for money, you can’t go far wrong with this C-rated Hisense Fully Integrated Dishwasher. While some reviewers questioned the overall build quality, this Which? Best Buy is an affordable option that is packed full of functionality to save time and energy.
Accommodating up to 16 place settings and with a top-level cutlery tray to maximise space, you’ll need to run it less often than other models, even in larger households. It’s spacious which makes it easy to stack, and it has flexible shelving that can even accommodate larger pots and pans.
We love the auto programme which tailors the cycle to your contents, while the 15-minute quick wash can get your dishes clean in a hurry if you have unexpected guests.
The quiet inverter motor runs efficiently too, with less friction meaning improved performance at a much lower volume.

What Mumsnet users say
Despite their significant price tag, Miele dishwashers come highly rated amongst Mumsnet users and consumers for their performance, longevity and quiet running volumes, but are also some of the most energy-efficient dishwashers you can buy today.
The Miele G7472SCVi Fully Integrated Dishwasher is a great example, boasting a first-rate A rating on the Universal Energy scale. Thanks to its EcoPower commercial pump, it offers fast and efficient cleaning results using less water - as little as six litres for a full load, which is pretty impressive when you consider hand washing can use up to 40 litres a time.
Accommodating up to 14 place settings, this integrated design is spacious enough to suit the majority of households and families, with a fully adjustable 3D Multi-Flex tray that helps you stash large pots, pans and bowls with ease.
We love the handy half-load function, which reduces the energy and water consumption if you need to run the appliance when the shelves aren’t quite full. You can also save money on detergent too thanks to the innovative AutoDos technology - this automatically adds the perfect amount of detergent during the wash.

The BEKO BDFN36560WCFG Freestanding Dishwasher comes with a glowing A energy rating, combined with a surprisingly affordable price tag.
With a capacity of up to 15 place settings, it's well suited to large households and families. It also has a ProSmart inverter motor, making it an efficient and quiet dishwasher to run - so you won’t disturb the peace if you start a cycle once the kids are in bed.
We love the Hygeine Intense programme that can rid your contents of bacteria during the wash and the unique rotating spray arms that get powerful jets into every corner for impressive cleaning results.
Thanks to the SelfDry function (which automatically opens the door at the end of the cycle) you won't need to run an additional drying cycle at the end, saving time and energy in the process.
Best slimline energy-efficient dishwasher
Siemens iQ300 SR23EI28ME Freestanding Dishwasher
Favourite button to remember your preferred programme
HomeConnect app allows you to control via your smartphone
VarioDrawer for cutlery and utensils
Quiet Mark approved
AquaSensor auto mode uses water based on how dirty your load is
29-minute quick wash
Less efficient than full-sized dishwashers
Key specs
Price on writing: £629 | Energy rating: D | Capacity: 10 place settings | Noise levels: 44dB | Eco cycle: Yes | Energy consumption: 211 kWh per 100 cycles | Water consumption per cycle: 9.5 litres
As a general rule, even the best slimline dishwashers don’t tend to be as efficient as their larger counterparts, with scores of D or E generally being the most common rating for compact appliances. While you will find some slimline Miele appliances with a higher C rating, this D-rated Siemens dishwasher is one of the best when considering overall value for money.
With space for up to 10 place settings, this Quiet Mark approved freestanding dishwasher is well suited to open-plan kitchens with flexible shelving and height-adjustable baskets that help you make the most of the space. With smart connectivity, it can even be controlled via your phone using the HomeConnect app.
To be more energy efficient, the AquaSensor mode automatically adjusts the water consumed based on how dirty the contents are, while dosage assist technology helps the detergent dissolve quickly and effectively, ensuring your dishes come out sparkling clean every single time.
While the eco wash uses the least water and energy, we love the option to run a 29-minute quick wash on the days when you’re pressed for time.
Are dishwashers efficient?
Dishwashers can vary quite considerably in terms of their energy rating (with appliances rated from A to G on the universal energy efficient scale). While traditionally dishwashers' high water and energy consumption meant they haven’t been very energy efficient, in recent years brands have worked hard to add new features and reduce the amount of electricity and water they consume.
What’s the best energy rating for a dishwasher?
It’s not uncommon to see dishwashers with a C, D or even E rating on the universal energy scale. However, if you’re prepared to spend more, you can pick up some really energy-efficient dishwashers that have low water and energy use. The best energy-efficient dishwashers have an energy rating of A to C.

How much does a dishwasher cost to run?
How much a dishwasher costs to run will depend on a number of factors including energy usage (measured in kWh) and their water use (in litres). You also may want to factor in the cost of dishwasher tablets and regular dishwasher maintenance such as rinse aid or dishwasher salt, especially if you live in a hard water area.
According to consumer champion Which?, the average cost of running your dishwasher is around £69 a year.
How to run a dishwasher more efficiently
Regardless of your dishwasher’s energy rating, there are a number of ways you can use your dishwasher more efficiently:
Use the eco cycle where possible - It may take longer, but the eco cycle is the most energy efficient, consuming less energy and water than quick wash and intense cycles.
Run full loads - Wherever possible you should only run the dishwasher when it's full. However, some dishwashers have a convenient half-load function, running a shorter cycle with less water to avoid wasting energy.
Don't overfill - Be careful not to overfill your dishwasher or stack it poorly, as this can prevent the spray heads from spinning effectively.
Don’t pre-rinse - Most modern dishwashers don’t require you to pre-rinse the dishes, no matter how tempting it may be. Except for significantly soiled pots and pans, you should be able to simply scrape leftover residue into your kitchen bin before adding them straight to a standard wash cycle.
Maintain your dishwasher effectively - Using a dishwasher cleaner, rinse aid and salt helps to keep your dishwasher running at its best.
Avoid using the dry cycle - Allowing the contents to air dry or drying plates with tea towels prevents the need to run a separate drying cycle at the end of each wash.
