Best Energy Saving Kettles 2024

It’s safe to say that we are a nation of tea drinkers, the average Brit drinks 884 cups of tea per year. The electric kettle was even invented here by the Russell Hobbs company in the 1950s. Since its first inception, the electric kettle has undergone a number of changes.

The principles remain the same, but more and more designers have tinkered with the design to improve either the look, speed, or energy usage. The shape, for instance, the early electric kettles copied the shape of stove top kettles, this has changed to more upright, cylindrical kettles that take up less space on the worktop.

In all honesty, the kettle design industry had reached the end of the road, or so we thought. Then they introduced the energy efficient kettle. These are similar to look at (in most cases) as a standard electric kettle, but they have features for saving energy and money. One feature that saves time, money, and water, is the ability to boil just enough water for one cup.

Most people boil at least twice as much water as they need, which wastes water, energy and of course time. So having a water level indicator that shows precisely how many cups of water you are boiling is an asset in the war against waste.

For many years electric kettles were unreliable, slow to boil, with little or no safety features, but today’s energy saving kettles have many features and functions to make your life easier. Read on for all the information you’ll need to make an informed choice on the best energy saving kettle for you

How Do Energy Saving Kettles Work

All electric kettles work on the same principle, the water is heated via an electric heat source, either an element or base plate that’s powered by electricity. When boiling point is reached the kettle cuts out and the water is ready to use for making tea, coffee etc.

Energy efficient kettles work on a similar principle but with an all important upgrade. The base plate heats the water in the same way but, and here’s the important bit, the amount of water you boil is much more controllable. Many allow you to heat up 300mls of water, that’s just enough for a standard cup.

A much more impressive feature is temperature control, it’s a well known fact amongst tea enthusiasts that different teas require different temperatures to release the flavours from the leaves. As a rough guide,

Green tea should be brewed at 75-80C

Instant coffee should be 80-85C

Oolong tea should be brewed at 85-90C

Black tea should be brewed at 100C

Most energy efficient kettles allow you to heat the water to preset temperatures which means you can enjoy your favourite hot beverage at exactly the right temperature and appreciate the full flavour.

What Are The Benefits Of Energy Saving Kettles

An energy efficient kettle is an upgraded electric kettle, in terms of design and energy saving. The benefits include,

Saving Money

By using just the amount of water you need to make your drink, you save water and electricity. Which means less financial outlay.

Time Saving

Energy efficient kettles boil faster than conventional electric kettles giving you more time to get on with your day.

Hidden Element

If the element never touches the water, it will not build up calcium deposits from the water supply. This means the time to heat ratio will remain constant.

Environmentally Friendly

Energy saving kettles use less water and less power which makes them the best choice for lowering your carbon footprint.


No need to keep watching the kettle as an energy efficient kettle will automatically turn itself off once it reaches the desired temperature. Plus many have temperature control settings which allow you to get the water at the optimum temperature for the beverage you are preparing.

Heat Saving

Energy saving kettles have much more insulation to stop heat escaping from the kettle. This allows faster boiling and keeps the water hot for longer if you get called away or distracted.

Temperature Presets

If you drink green tea for example, the water temperature should only be between 75-80 degrees C. This can be hard to ascertain with a conventional electric kettle. Energy saving kettles however, have a temperature control so you can preset your water temperature for optimum brewing.

Green Materials

Most energy saving kettles are manufactured from either glass or metal (usually stainless steel) these have much less impact on the environment than kettles made from plastic. Also many plastic kettles contain BPA, a truly harmful chemical.

What Are The Disadvantages Of Energy Saving Kettles

The only real disadvantage of using an energy efficient kettle is also a disadvantage of using any electric kettle. That is if you lose electricity, you can’t use it. Whereas a kettle on a gas hob would still work in a power outage.

If you live in a hard water area, limescale build up is inevitable. This not only affects the amount of time it takes to heat up the water, and the energy consumed. It also affects the taste of your beverage too.

Many energy efficient kettles have built in filters to prevent the build up of limescale, and keeps your kettle working as efficiently as ever.

One Cup Indicator

This eco friendly feature saves energy, water, money and allows you to just boil the exact amount of water you need.

Water Level Indicator

The water level indicator is usually located on the side or handle of the kettle.This feature ensures you only boil the amount of water you need. Saving water, time, energy and money. 

Rapid Boil

This feature saves time if for instance, you like a hot drink in the morning but often get up later than you should.

Temperature setting Control

This feature allows you to set the exact temperature the water heats to. Essential if you are a tea aficionado. 


Energy efficient kettles come with a variety of safety features, here are some of the important ones to look out for.

Auto Shut Off

Once the water reaches the desired temperature, the kettle will automatically shut off. Saving energy and preventing the kettle from boiling dry.

Slow Release Lid

This prevents water from splashing, preventing spillage and scalding.

Boil Dry Protection

When in a hurry, it’s so easy to turn the kettle on without checking the water level first. If it boils without having any water, you can damage internal components and/or the heating element. Boil dry protection prevents this from happening.


Some energy efficient kettles look like conventional electric kettles, but there are also other designs. Some look like water dispensers,some like jugs, there are even some models that look like the old fashioned stove top type kettles.
