Best energy-saving kettles
Kettles all use a similar amount of energy to boil a litre of water, but that doesn’t mean they’re all equally efficient. If a kettle switches off immediately after boiling and has a low minimum fill level, it can help you save energy and money, as this means you don’t have to boil more water than you need.
We take this into account when awarding products Energy Saver status - a label we give to Best Buy kettles that successfully pair superb performance with low energy use. Not only will these kettles make a first-class cuppa, they’ll also trim your electricity bills.
To qualify as an Energy Saver, a kettle must have a brief overboil time and low minimum fill level. That way, we know that they do more to keep electricity usage down.

Kettle energy-saving tips
- Boil only the amount of water you need - boiling a litre of water often uses more than twice the energy it takes to boil the minimum amount.
- Descale your kettle regularly - if it’s full of limescale, it uses more energy to boil the same amount of water.
- Choose a kettle with a low minimum fill - this means you won’t waste energy by boiling more water than you need.
