Best fast boil kettle


If you're always gasping for a tea, this model will deliver the goods in a speedy 2 minutes 18 seconds. With its low minimum fill, tea for one is even quicker - you'll be waiting just 44 seconds.

Best cheap kettle


You can pick up this bargain Best Buy kettle for under £20, but there’s nothing budget about its performance. It’s energy efficient, quick to boil and easy to use, and beats kettles more than five times its price.

Best glass kettle

Best quiet kettle


Few kettles score a full 5 for noise, and this kettle is no exception, but it is one of the quietest we've tested in the last few years. Its also a great all-rounder, being fast, energy efficient, easy to use and effective at keeping limescale out of your cup of tea. At 81% it's a high scoring Best Buy.

Best one cup kettle


If you’re looking for an energy efficient kettle, this one fits the bill. You can boil just one cup’s worth of water, and it’s ready in a super speedy 48 seconds. It’s also easy to use and has an effective limescale filter, all for a bargain price.

Three kettles to avoid

You wouldn't think a kettle could go that wrong, but we've uncovered some shockers in our tests. Poor kettles are slow to boil, waste energy, make a racket or are a real hassle to use. These are the models to steer clear of:

Not worth the price tag


If you aren’t put off by the price tag, the sleek and modern design of this kettle might catch your eye. Its digital controls may seem impressive, but they make it hard to use. It also boils for longer than necessary, wasting energy, and has a poor limescale filter that fails to prevent bitty limescale from escaping into your tea. It’s our worst Don’t Buy to date.

Style over substance


This kettle has style in spades, but falls short of the mark when it comes to the essentials. It takes ages to turn itself off after boiling, wasting electricity. It also has a terrible limescale filter and is really heavy, making it awkward to use. It’s definitely best avoided.

Cheap and disappointing


You need to boil a minimum of one litre of water to use this kettle, making it one of the most wasteful we’ve seen. We also don’t like the limescale filter and how long it keeps you waiting. It’s not worth even the small investment.

Buying the best kettle for you

Here are four key things to consider when choosing a kettle: 

1. Price

The cheapest kettles we test are around the £10 mark, with the most expensive setting you back nearly £200. More expensive kettles tend to be made of metal or glass, and have extras such as multiple temperature settings. When it comes to getting the basics right though, we’ve found cheap kettles that outclass pricier rivals in our tests. If you’re looking for a kettle that goes the extra mile, lighting up as it boils or ringing when it’s finished, then it may be worth splashing out. But for a good basic kettle, you could find a bargain at a lower price. See our kettle reviews to find the best value options.

2. Looks

If you have an open-plan kitchen, you may be concerned with how your kettle is going to look on your worktop. Luckily, most of the products available have aesthetics in mind, and you can get a good-looking kettle to suit your personal taste. We’ve found Best Buys in every possible colour and finish, including some stylish budget buys, so check our kettle reviews to find the perfect match for you. 

3. Performance

Our independent testing is designed to put every kettle on a level playing field, no matter what the price, and see if it will do its job well when you get it home. We research the features that you care most about in your kettle and reflect this in our tests, so you can be sure that you buy a kettle that won’t let you down. Our scores are broken down into ease of use, speed, energy use, noise and the quality of the limescale filter, so you can always find a good all-rounder amongst our Best Buys. Find out more about how we test kettles.

4. Reliability

Kettles are one of the most breakdown-prone small appliances, according to our 2017 reliability survey. If you’re sick of traipsing to the shops every few years for a replacement, check our guide to the most reliable kettle brands to find out which kettle brands are more likely to last the distance.
