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.
In order to be eco-friendly, 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.
