As we're all putting increased efforts into living a more sustainable life, energy-efficient alternatives have been popping up for pretty much all our household essentials, from oven alternatives to cheaper heating options. And kettles are no exception either.

Certain features can improve a kettle's energy efficiency. Heat preservation, fast boiling and temperature control settings are great in reducing the power required from a kettle.

A kettle requires between 1200W and 3000W to boil, and all those cups of tea and coffee can add up to have an impact on your energy usage over time. If you're looking to reduce your energy consumption and your carbon footprint, consider replacing your current model with an eco kettle.

Tried and tested: best eco-kettles at a glance


How we tested eco kettles

Our testing was based on boiling 500ml water – enough to fill two average-sized mugs – to 100ºC, and we awarded each model up to 15 points for the following criteria:

  • Energy efficiency, including whether the kettle offers a rapid boil function, different temperature settings and a keep warm feature (3 points)
  • Features, points awarded for water level window, boil-dry protection, auto shut-off, cordless design, 360º base, built-in filter, hidden element and ease of pouring (8 points)
  • Value for money, does it offer plenty of features, and does it come with a warranty? (2 points)
  • Good looks, is the kettle stylish, and does it come in any different finishes? (2 points)

Should you buy it?

The Bosch Styline ticks nearly all our criteria boxes. The double-walled, cool-touch exterior is great for peace of mind when it comes to safety, and also helps to keep the boiled water hotter for longer. We like its minimal, fuss-free design too. It is on the pricier side though.

  • Especially good pouring with the large, easy-to-hold handle.

How energy efficient is the Russell Hobbs illuminating glass kettle?

Although it doesn’t offer different temperatures or a keep warm function, and isn’t officially classed as rapid boil, this smart 3000W kettle only took around 1 minute 25 seconds to get 500ml water to boiling point. Its glass body allows you to see exactly how much water is inside, so you don’t need to boil any more than you need. There’s a clear indicator for one cup, which Russell Hobbs claims will save up to 66% on energy in comparison to boiling a litre of water – ideal if you’re just making a single cup of tea or coffee.

Is the Russell Hobbs illuminating glass kettle good value for money?

Although one of the more pricey models we tested, we think it’s worth it due to the wide range of features, as well as the two-year warranty.

In terms of good looks, this model doesn’t disappoint. The blue light which illuminates when boiling adds a modern touch to your work surface, and it’s also available in a copper finish.

Should you buy it?

It has a good range of standard features, and a stunning glass design with clear markings for water level. The only drawback is it did prove to be quite heavy when filled with water.

This 1.7L model’s main eco-credentials are based on sustainability rather than features. It’s designed with 100% bio-based plastics to reduce its CO2 footprint by 25% during the production process. It doesn't offer rapid boil but it took just 20 seconds longer than the Russell Hobbs to boil 500ml of water, around 1 minute 45 seconds, and uses less power (2200W). It also has a clear water level indicator, which includes a one-cup measure, ensuring you’re not wasting energy by boiling any more water than you need.

As well as its eco-conscious design, it looks great, with a minimal, almost Scandi feel which will look fantastic in any kitchen. We also liked the soothing white light on the power switch.

Should you buy it?

If you love chic, Nordic style, this could be the kettle for you, plus it’s made using bio-based plastic. In 2022, it was also awarded two design awards.

Although not the most stylish kettle we tested, it is available in a choice of black, white or stainless steel finishes (these do vary in price).

Should you buy it?

The fast boil makes the Duronic EK30 Eco Kettle super speedy, meaning you won’t need to wait long for your morning cup of tea or coffee. We found that the spout dribbled a little towards the end of pouring though.


5. VonShef Variable Temperature Kettle, £49.99

Best temperature control kettle

  • Score: 13/15
  • Buy now from VonHaus (RRP £49.99, now £44.99)

With a good combination of both standard and eco features, this kettle is a great buy under £50, and comes with a two-year warranty.

How does the VonShef variable temperature kettle look?

Although it only comes in one finish, the stainless steel design is smart and would suit most kitchen schemes.

Should you buy it?

There is a slight delay in the time it takes the auto shut off to kick in once boiled, which we feel could be reduced to help save energy but the VonShef Variable was very easy to use, and it ranks highly on energy-saving features and general features.


6. Vektra 1.5L Vacuum Electric Kettle, around £60

Best quiet kettle

  • Score: 8/15
  • Buy now from Wayfair (RRP: £96.25, now £64.53)
Vektra Vacuum Insulated Eco Friendly Kettle review

Features

  • Boil dry protection
  • Auto shut-off
  • Cordless design
  • 360º base
  • Hidden element
  • Easy pouring

How energy efficient is the Vektra Vacuum Electric Kettle?

The only real energy-saving feature of this kettle is its double-walled vacuum flask design, which keeps water warm for up to four hours after boiling, meaning that you’re saving energy by not having to reboil frequently. It uses between 1.5kw and 1.8kw of energy, and reaches boiling point in around two minutes 30 seconds for 500ml.

Vektra Vacuum Insulated Eco Friendly Kettle review

Is the Vektra Vacuum Electric Kettle good value for money?

Priced at around the £70 mark at the time of writing, we feel that the absence of some quite standard features means that this model isn’t the best in terms of value. It does, however, come with a two-year warranty.

How does the Vektra Vacuum Electric Kettle look?

The design isn't hugely stylish but it’s available in a wide choice of five colours, as well as different capacities.

Should you buy it?

This kettle is very quiet to boil, so it’s ideal for those with open-plan kitchen/living areas. The vacuum technology stayed true to its claim of keeping boiled water warm at around 80ºC for up to two hours, and at around 68º for up to four hours. That being said, this model is quite slow to reach boiling point compared to the others we tested, and we also found the pouring system a little tricky, as you have to depress the lever while tilting the kettle at quite an angle.


7. Dunelm Contemporary Jug Kettle, 1.7L

Best stylish eco kettle

  • Score: 11/15

Is the Dunelm Contemporary Jug Kettle good value for money?

This is one of the cheaper kettles in our test, and comes with a two-year warranty. However, it only has two of the three energy-saving functions, so it’s not the best eco-option to go for..

How does the Dunelm Contemporary Jug Kettle look?

In terms of looks, this design is super-stylish, with it’s two-toned wood and matt finish. It comes in a fashionable array of colours (grey, white, cream and yellow), which are also available in the matching toaster. We liked the light on the power-on switch, too.

Dunelm Contemporary Kettle

Should you buy it?

The Dunelm Contemporary Jug Kettle ticks many of the boxes, but in terms of energy-efficiency, you might want more than just a rapid-boil feature.

FAQs: What is an eco kettle?

Eco kettles are designed to use less power with each boil. They're also produced with the intention of lowering the environmental impact from their materials and manufacturing process.

Certain features can improve a kettle's energy efficiency. Heat preservation, fast boiling and temperature control settings are great in reducing the power required from a kettle, as well as using sustainable materials when constructing them.

Stovetop kettles can be good for the planet, too, as their carbon footprint from manufacturing can be much lower.

What to look for when buying an eco-kettle?

“If you’re in the market for a new kettle, choosing one with a rapid boil function is a great option as it heats the water up much faster than your average kettle. Equally, picking one with a ‘keep warm’ setting will mean you can go back for a brew later without having to boil the kettle again.

Having a kettle that has a high level of limescale build up can be a factor as to why your kettle is using more energy than it should be. This is because the water will take much longer to boil.” - Katy Roberts, AO.com’s kettle expert
