If you are on the hunt for the best energy-saving kettle to save you on your bills in the long term, then look no further. Typically, electric kettles are an excellent energy-efficient option - they are substantially more power-savvy than their stove-top counterparts and can also turn themselves off once boiling stops, cutting off any unnecessary power usage. While overfilling remains common, it's best to boil just the required amount of energy. Let's get into our guide for the best kettles for your needs.
Modern smart meters offer a window into our daily consumption, both in terms of water and electricity. These meters allow you to look over your kettle's frequency of use, the energy it requires, and the amount of warm water that goes unused. Particularly in colder months, our kettle's usage tends to go up. Long story short - a faster boiling means less energy consumption over time, and kettles with around 3kW wattage typically boil quickest. You can find many kettles that fit this criteria, from the best quiet kettles to smart kettles.

Best temperature control kettle

www.sageappliances.com
This Sage Smart Kettle isn't necessarily smart in the conventional way but refers to the temperature control that brings out the best in 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."
Pros
- Effective - does produce better-tasting tea and coffee

What to consider when buying a kettle
Kettles have long been kitchen mainstays for more than just brewing tea. From your morning coffee to instant meals like pasta, they play a surprisingly versatile role in our daily culinary routines. But what should you keep in mind when selecting one?
Energy-saving: If being eco-friendly is a top priority, an electric kettle is your best bet. They typically operate between 2-3kW. Remember, higher wattage translates to quicker boiling times. Little fact - the first automatic stainless steel kettle was by Russell Hobbs in 1955, using steam to trigger an auto shut-off, ensuring efficiency and safety.
Limescale filter: Especially useful for those in hard water regions, choose a kettle specifically designed to combat limescale build-up to ensure you have purer water.
Water level indicator: A clear indicator helps you fill just the right amount of water, avoiding energy waste from boiling more than needed.
Advanced features: If you're willing to invest a bit more, modern smart kettles come packed with features like silent boiling, precise temperature settings, prolonged 'keep warm' settings, voice commands, and even app compatibility.
FAQs: Best energy-saving kettle
How do I measure the energy consumption of my kettle?
One way to see how much energy your kettle is using is to do an experiment with your smart metre's in-home display (IHD). An IHD shows you how much energy you're using in kilowatt hours (kWh) and it shows how much it costs. Citizens Advice suggests turning off all devices, except essential electricals, then using your kettle to see how much it costs you.
If you don't have an in-home display or smart meter, you can work out how much your kettle costs to use with this equation:
Appliance Power (W) x Amount of Time Used (p/h) x GBP per kWh (0.33) / 100 = Price Per Use
As of April 2023 the unit rate for electricity is on average 33.21p/kWh.
Amount of Time must be in decimals (0.5 is 30mins, 1.5 is 90mins)
For example, if you've totted up that you use your 3000W kettle for 15 minutes a day the sum is:
3000 x 0.25 x 0.33 / 100
Rounded up, it works out at 2.5 pence a day to use a kettle.
Are smart kettles energy-efficient?
Many smart kettles come with energy-saving features such as precise temperature control, which means you only use as much energy as needed for your desired temperature. However, always check the product specifications and reviews to ensure energy efficiency.
