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.”

Customer review: "As a house of addicted tea drinkers, we boil the kettle a LOT. We’ve been through expensive kettles and the cheapest ones, so this time wanted a middle-of-the-road kettle that was more eco friendly and looked good too. This is the best kettle we’ve ever had. You can boil just one cup super quick, it’s super lightweight and looks great too. Really delighted with this purchase."

Breville’s Edge Kettle is a combination of efficiency and style. Ingeniously designed, its water indicator transitions from white to red upon boiling and remains so until the temperature dips below 80 degrees Celsius. This offers a visible cue for reheating requirements. Crafted from durable brushed stainless steel, this kettle is excellent value.

Customer review: "Great kettle. It’s quick to boil, fairly quiet but the red light feature, where it stays red to indicate the water is still at boiling temperature is PERFECT. I have a lodger who often makes a cuppa before me, but I always fill and boil before I make mine. Several mornings now, the kettle is red, so I just pour what’s left in the cup and a perfect brew is made without having to re-boil. Obviously, saving me a bit of electricity at the same time."

Zwilling's Enfinigy glass kettle has a transparent design so you can see your water boil in real time. Part of a range of Enfinigy products that include toasters, coffee machines and food processors by Zwilling. Made from high-quality materials with innovative design, these appliances are designed to be long-lasting. There are a range of kettles to choose from that feature temperature control. We love this Zwilling Enfinigy Glass Kettle because it lets you steep tea and because it's made of glass you can watch the water change colour. Also, the pre-boil feature, which heats water to boiling point and automatically cools it down to the desired temperature, is invaluable if you are sterilising bottles.

Customer review: "This is a great product with a high quality design. Four option for the temperature can be chosen (60, 70, 80, tea temperature and 100 degree). The inner filter can also be removed and you can keep the water warm in the kettle. Highly recommended."

This Sage Smart Kettle isn't necessarily smart in the conventional way but refers to the temperature control brings out the best from green, white, or oolong teas. The kettle features five preset temperatures and a maintain-heat function for 20 uninterrupted minutes. Its user-friendly design showcases a prominent, illuminated start/cancel button and a detachable limescale-catching filter.

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 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.

"It's a smart looking kettle too, made of brushed stainless steel. Neat and compact, unlike the Zwilling Enfinigy Glass Kettle which has a deeper base. The ergonomic handle stays cool and the soft top lid opens gently to prevent splashing. There are dual water level indicator windows, so you can see the water level if you're using it left or right-handed. It stands steady and securely on its power base, the button controls are easy to use and there's an audible beep when the kettle's boiled. Overall, the product feels very well made. The spout is over large but that has benefits as it gives an even pour. It boils fast, just a tad noisy, but no biggie.

"Finally, I loved the keep warm feature. My freshly boiled water stayed at a constant temperature, while I prepared my cast iron teapot and spooned green tea leaves in. I loved the ritual and thoroughly enjoyed savouring this on a sunny morning by my parent's fish pond with the flag irises in full flower."

Compact yet efficient, the Quest Kettle is ideal for individual users or smaller households. Despite its lightweight design (790g), it boasts features like a water-level display and a pivoting lid. It's particularly senior-friendly too. Energy savers will appreciate its low wattage, though a bit more patience is needed for boiling.

Customer review: "It’s a good kettle it’s cute and small but I didn’t realise that when I bought it but it’s good for what it is. But for me it takes quite some time to boil the water. Also is good in its noise it doesn’t make much noise when boiling."

Merging the perks of a double-walled vacuum flask with an eco-friendly kettle, this Vektra model is an excellent pick. It keeps water piping hot for up to four hours. Crafted from premium 18/8 stainless steel, this robust kettle promises longevity, plus its design saves reboiling hassles.

Customer review: "This really is the best kettle I could have imagined for economy and eco-friendliness. I am amazed at how simple the technology is and why everyone is not doing it. The kettle is basically a thermos flask. Because the water is under pressure and insulated it boils really quickly and until you press the lever on the handle it doesn’t release any water, steam or lose any temperature. It keeps its contents hot enough to make coffee or tea for over an hour. The spout and pour lever are incredibly well engineered to only allow a sensible amount of liquid out in a steady flow."
