A handful of them can even be controlled via your voice too, with devices like Amazon Alexa or Google Home. You may stop to question whether smart kettles are just a whole new level of laziness, but there are actually quite a few benefits to having one, including, being energy saving appliances.

There are not too many on the market, but we've rounded up the best ones you can buy now, as well as everything you need to know about them.

A smart kettle can be controlled via an app on your phone, as well as still being used exactly the same as your regular quiet kettle. With the app, you're able to turn your kettle on and off, pre-set it to different temperatures and select boil times. Most models have a 'keep warm' function too, so your water will remain at a specific temperature for a certain period of time. Others will even tell you how much water is left in your kettle, as they typically don't have a water gauge on the side.

A lot of brands now offer 'smart tech' for your home, so if you are simply someone who loves the latest bit of tech or ultra-modern designs, such as a sleek stainless steel kettle, then a smart kettle could be a great purchase. Not all smart kettles can be controlled by your voice, but a few that we've included below — such as the Smarter iKettle and Swan Alexa Smart Kettle — can. Just tell the kettle your command, and it will grant you your wish.

Best Smart Kettles

Best overall smart kettle

This attractive and sleek-looking kettle from iKettle does everything you'd want from your smart kettle — it has voice control that's compatible with your Alexa or Google Home, it can be controlled via an app and has different temperature variations. This kettle can be set to temperatures between 20°C and 100°C, which can be kept warm with the 'keep warm' function. You can even set up a schedule for it to boil at a specific time every day with the 'wake up' and 'home' modes. Plus, we love that it's available in three different neutral colours to suit all kitchen interiors.

Customer review: "This kettle is good. It is working well with Alexa. The app shows you water level and you can set how long you want it to be kept warm for once boiled. It can be operated manually or by App or Alexa. I love being able to ask Alexa to make a brew! The small downside was it was difficult to set up."


  • Large water capacity
  • Can control via your voice and app
  • 'Keep warm' function
  • Variable temperature options
  • Stylish design and colours available


  • Doesn't have double-wall technology, so the exterior will get hot

Best smart kettle for Alexa devices

Another voice-controlled kettle is the Swan Alexa Smart Kettle. Create personalised commands and routines unique to you, such as turning the kettle on, changing the temperature of the water or asking Alexa to keep the water warm. It makes 8-10 cups, and you can select the temperature between 60°C, 85°C, 90°C or 100°C. 

Our review: "As a big brew lover, and someone that works from home, I was very excited to test this kettle out. It was very easy to set up following the booklet that has simple and straightforward instructions. But do make sure you take the time to read this. At the start, I wasn't sure why Alexa kept being so disobedient and not turning on my kettle when asked to, but this is because I hadn't set up my voice commands in the Alexa app. Once I had done this, Alexa would boil the kettle whenever I asked. Controlling the kettle from my phone was great, especially on those lazy Sundays when I just wanted a few extra minutes in bed. The 'keep warm' function is brilliant too, as I'm prone to flicking the kettle on and then getting distracted by another task.

"I was also amazed by the double-wall technology, which stops the exterior from getting hot — no more kettle burns for Bryony. The only thing I would say is this kettle isn't the quietest at all, but if you're looking for a smart kettle that's sleek and stylish, and very easy to use, it's definitely worth considering."


  • Stylish, sleek design
  • Can control via your voice and app
  • 'Keep warm' function
  • Variable temperature options
  • Exterior doesn't get hot when boiling


  • Noisy

Best introductory smart kettle

The Xiaomi Mi Smart Kettle Pro is an aesthetically great-looking kettle, but unlike the ones above, it doesn't have voice control. It does, however, come with an app where you can set it to variable temperatures and customise a 'keep warm' temperature between 40°C and 90°C for up to 12 hours.

This kettle also has double-wall technology, which prevents the exterior from heating up while boiling. And we really appreciate its triple power protection too, where the kettle automatically turns off after boiling, if dry-boiling is detected and it's electric shock resistant. Overall, it's a good one to start with if you're keen to dip your toe in the pool of smart kettles but aren't quite ready to make the full leap.

Customer review: "It's my favourite kitchen device. I like just to make the water warm for the tea and not to boil it again. Easy to use, no issues noticed."


  • Beautiful design
  • Affordable
  • Can control temperatures via the app
  • Double-wall protection


  • Comes with a European plug, so need to purchase an adaptor

Best for temperature controls

As well as voice control, temperature variations between 40°C and 100°C and being able to control it from your phone, the Weekett has some added bonuses. Unlike its competitors above, this Weekett Smart Kettle has a water gauge on each side of it, making it ideal for both left and right-handed users. The platform it also sits on has different temperature options for quick selection on those days you've misplaced your phone. There's a built-in baby bottle programme for new parents too, which boils the water to 100°C and then cools it to 70°C, where it will stay at this temperature for an hour. Plus, there's a removable limescale filter to ensure a fresh brew with every boil and dry-boil protection.

Customer review: "I really like this kettle, it looks nice and the best feature is that you can operate it remotely with the app or your smart speaker, which is very cool. I found the Wi-Fi quite easy to set up once I figured out how to do it, hasn't lost the connection yet after a couple of days of using it. The only thing that would have been nice is a fill level detection in the app."


  • Water gauge on both sides — good for left and right-handed people
  • Can control via your voice and app
  • Good water capacity
  • Variable temperature options


  • App doesn't tell you the water levels

Other 'Smarter' Kettles To Consider For Your Kitchen...

If you're not completely ready to dedicate yourself to a smart kettle, then we've pulled together some other kettle options with cool features, such as temperature variation controls.

Best for tea connoisseurs

If you take your tea seriously, then this kettle from Sage will take brewing to a whole new level. Add your tea leaves to the steel basket, select your temperature on the base and how long you would like it to brew for, then sit back and relax as your tea boils to perfection and brews just to your liking. The steel basket is dishwasher safe, and the kettle can also be used to boil water for other hot drinks.

Customer review: "Excellent product, looks great, fast boiling and lets you know when boiling is complete. 
Definitely recommend."


  • Temperature and brew time selection
  • Keep warm function
  • Can also use to boil other hot drinks
  • Sleek design


  • A little heavy

Best for ease of use

This kettle from Bosch allows you to select your water temperature at either 70°C, 80°C, 90°C and 100°C, via the buttons on its base. It's pretty modern-looking and is available in both black and white. It has dry-boil protection, a concealed heating element and a keep warm button, which lasts 30 minutes. There's extra storage in the base of the kettle for its cord, and the limescale filter ensures a perfect cuppa with every pour. It's also available to buy with a matching toaster.

Customer review: "As I worked in the kitchen industry, I was always an advocate of Bosch kitchen appliances but had never bought a small appliance. This is absolutely first class. Temperature control is great for coffee or warming glasses etc, a little noisier, but small price to pay. You will not be disappointed."


  • Temperature selection via the base — ideal for tea and coffee connoisseurs
  • Keep warm button
  • Concealed heating
  • Limescale filter


  • Not the largest water capacity

Best for serious tea and coffee connoisseurs

This Sage Smart Kettle looks almost identical to the Weekett Smart Kettle. If you're big on perfectly brewed tea and coffee, then this kettle is ideal, as there are five different temperature options on the base for Black, Green, White or Oolong teas and French Press Coffee. There's also a 20-minute keep warm button.

Our review: "If you are a really particular tea or coffee drinker this is the kettle to go for. Being metal it naturally keeps water warmer for longer. Sage's the Smart Kettle has been developed with Heston Blumenthal with the USP of getting the maximum flavour from tea and coffee by adding water that's the optimum temperature to release tasting notes and aromas. And it's true - coffee does have more flavour when boiled at 90 degrees. Also, green tea tastes delicious boiled at 80 degrees, allowing the delicate flavour of the leaves and jasmine to shine through."


  • Temperature selection via the base — ideal for tea and coffee connoisseurs
  • Keep warm button


  • Not the most stylish design

OUR VERDICT: Which Is The Best Smart Kettle?

Although it was a hard decision between the Alexa Swan Kettle and the iKettle, for us, the Smarter iKettle comes out slightly on top. This is mainly because it is compatible with your Google Home devices, as well as your Alexa, whereas the Swan can only be used with the latter. As well as its compatibility, there's no denying the iKettle's sleek and stylish exterior — it's a kettle anybody would be proud to have on their kitchen countertop. Plus, the fact it's available in a range of neutral colours means you can find something to suit your kitchen. The temperature variation (between 20°C and 100°C) is a lot faster than its competitors too, and the app is simple and straightforward to use.


What are the benefits of a smart kettle?

As well as being really convenient, if you suffer from mobility issues, you may find these kettles to be particularly useful. Rather than having to constantly walk to the kitchen to turn the kettle on, it can be done from your phone or via voice control. New parents benefit from them too, as the kettle can boil to 100°C and then let it cool to 70°C for when making up bottles. The Weekett Kettle even has a baby bottle programme. Keep warm functions are extremely useful to prevent you from boiling the kettle multiple times too, and the different temperature variations are ideal for tea and coffee connoisseurs.

How do smart kettles work?

You will need a WiFi connection to use this type of kettle. This is so you can connect it to your phone and then be able to control it with this.

Once you have your smart kettle, you'll need to follow the instructions, which will usually prompt you to download the compatible app. Apart from then needing to fill the kettle up yourself, you will then be able to carry out different tasks via the app, which may include:

• Switching your kettle on/off

• Checking the water levels inside

• Setting different temperatures

• Turning on a 'keep warm' setting

• Adding different voice commands for your kettle to recognise

Smart kettles will also have buttons on them (even if they're digital), so you can also use them exactly the same as a regular kettle. Multiple people in your household will be able to download the app, so they can control the kettle from their phones too.

How do I clean my smart kettle?

Regardless of whether you have a glass or stainless steel kettle, clean your kettle exactly the same way as you would your regular kettle with some decent descaler. Although some smart kettles, such as the Alexa Swan Kettle, will tell you when it needs descaling via the app.

You can also clean your kettle naturally with some store cupboard essentials, like lemon juice. Just fill your kettle half full with lemon juice and half water, then boil. Once the kettle has boiled, let it sit for 30 minutes before emptying it. This should remove any limescale build-up and leave your kettle smelling fresh.

Even if you don't live in a hard water area or have a water softener, we still recommend you clean your kettle out every few weeks. If you're not sure of the difference between these two types of water, we have a guide for hard water and soft water that can help you out.
