This kettle isn't just fast - it's the fastest kettle we've tested in the past eight years. It boils a litre of water in just two minutes and 14 seconds, and a single cup takes a lightning-quick 49 seconds.

This kettle was a real surprise - it's the cheapest Best Buy we've found in years. It does everything you'd want it to - it's quiet, boils quickly, is easy to use, and has good limescale filter.

We haven’t always been impressed with glass kettles, but this model scored well in our tests. It’s very quick, boiling a litre of water in less than two-and-a-half minutes, and energy efficient too. At 80%, it’s the highest scoring Best Buy glass kettle.

This is the quietest kettle we've tested in the past six years, so if you're after a kettle that won't cause a commotion, look no further. It's also fast, taking just two and a half minutes to boil four cups of water, and can boil as little as one small cup.

You can boil as little as 200ml in this kettle, so there's no need to waste time or electricity on boiling extra water - even if you only need enough for a small mug. It also boils quickly, is easy to use, and comes in a variety of colours.

Why Which? kettle reviews are better

We test kettles more thoroughly than anyone else, and because Which? is independent and doesn't accept advertising or freebies, you can trust our reviews to give you the full, honest and impartial truth.

We check how long each kettle takes to boil, how much noise it makes when doing so, and whether it wastes energy by boiling for longer than necessary. We also inspect each limescale filter to check whether it's well-fitting, durable and effective at keeping bitty scale out of your drinks, and we pour cup after cup to assess how easy the kettle is to lift, fill, carry and pour.

The best kettles boil quickly and quietly, have a filter that keeps out pesky bits of limescale, and have large, clear windows that make it easy to see how much water is inside. The worst kettles make a racket while boiling, require you to boil extra water unnecessarily, and are heavy and awkward to fill up.
