Choosing an energy-efficient electric kettle isn’t just about saving money on your electricity bill—it’s also about reducing waste and making a more sustainable choice. With so many options on the market, it can be tricky to figure out which ones actually use less power without compromising on performance. So, let’s look at some of the best energy-saving kettles and what makes them stand out.

How Much Energy Can I Save with an Efficient Kettle?
It depends on how much tea, coffee, or instant noodles you’re making! A standard kettle can use quite a bit of electricity, especially if you’re constantly overfilling it. Energy-efficient models can cut power use by around 20–30%, thanks to features like rapid boil technology and better insulation.
Let’s say you boil a full kettle (1.5 litres) a few times a day. A standard model could use around 0.11 kWh per boil, adding up to roughly £30 a year on your energy bill. A more efficient kettle might shave £5–£10 off that by using less electricity for the same job. It’s not life-changing, but over time, those savings add up—especially if everyone in the house is constantly boiling water.
What’s the Best Way to Use a Kettle Efficiently?
The easiest trick? Only boil as much water as you need. It sounds obvious, but loads of people fill the kettle to the max for just one cup. That’s like heating a whole oven for a single slice of toast.
Another thing—keep your kettle clean. Limescale buildup makes it work harder, which means more electricity use. A quick descale with vinegar or a descaling solution every few months keeps it running efficiently.
Are Kettles Energy Rated?
No, kettles don’t come with an official energy rating like fridges or washing machines. There’s no government-approved label that ranks them from A to G based on efficiency. This is because kettles are relatively small appliances that don’t run continuously, so their overall energy impact is lower compared to things like ovens or dishwashers.
