Why you can trust our kettle reviews

We've tested hundreds of kettles over the years, so we know how to sort the best from the rest. 

Which? is independent – we work for our members, not brands or advertisers. Third parties don't influence us and we buy all the products we test ourselves. We don't accept freebies from product manufacturers or retailers.

We test kettles in a lab, not a kitchen. Our tests are impartial and objective. We test each appliance to the same standard, so it's easy to compare different models.

Our product recommendations are influenced only by these independent test results so our advice is unbiased and can help you avoid avoid costly mistakes.

The top kettles from our tests are fast, easy to use and clean, energy efficient and have decent limescale filters. These are our Best Buys.

Best kettle features to look for

When buying a new electric kettle, there are a few important things to look for:

• A minimum fill of 300ml or less Boiling a litre of water often uses more than twice the energy it takes to boil 500ml. So if you’re a habitual tea or coffee drinker, the option to boil water for just one cuppa will save you both time and money.
• A tight-fitting limescale filter It doesn’t matter how good your filter is at catching flakes if there’s a gap that lets limescale slip through. Before buying a kettle, check if you can remove the limescale filter to clean it and look at how snugly it fits the spout.
• A generous maximum fill The bigger a kettle’s maximum capacity, the better. You don’t want to end up hastily boiling another litre because there’s not enough hot water for guests. Most kettles hold around 1.7 litres – enough for around seven cups.
• Quick to boil The power of a kettle ranges from about 2.2kW to 3kW. Higher-wattage kettles are more powerful – they boil faster, which uses less energy. Most kettles now have a wattage of 3kW, but we've found that kettles with similar power levels don't always boil at the same speed. Our kettle reviews tell you how long a kettle takes to boil a litre of water, so we can find the fastest models.
• Quick to switch off after boiling A kettle that shuts off quickly once the water reaches boiling point will help to cut your electricity bill. Nearly all new electric kettles switch off automatically, but look for a model that overboils for less than five seconds if you want a really efficient kettle. Our reviews will warn you if a kettle is guilty of overboiling.

Outside of these important considerations, you'll also want to factor in your style and budget.

Style-wise, dome or pyramid kettles have a traditional domed shape with a handle on the top, while jug kettles have a taller jug shape with a handle on the side. You'll usually find the water gauge is larger and easier to see on a jug kettle, and the lid can be a bit more fiddly to remove on dome models.

Plastic kettles tend to be lighter than stainless steel or glass – look for one that weighs less than 1kg if you want something that's nice and light.

How much do I need to pay for a kettle?

• Kettle prices range from £10 to more than £100
• We've found good and bad models at both ends of the price spectrum

You can buy a no-frills own-brand kettle for less than a tenner, so what exactly do you get when you pay more?

You're often paying for a premium style, materials and finish. You're also more likely to get extra features such as variable temperature settings. 

Cheaper kettles usually have a more basic metal or plastic design and stick to the basic job of boiling water,. However, we've seen some pretty stylish budget kettles produced by brands such as Argos and Asda. Budget kettles are also less likely to have a one-cup boil feature, although some models buck the trend. 

We've found some brilliant cheaper kettles, and some terrible expensive ones, so paying more doesn't guarantee a good result. You can find Best Buy kettles starting from £20.

Shopping on a budget? Choose a Great Value kettle: these are at least 20% cheaper than average and score 60% or more, so you get a decent product at a decent price. 

Boiling water taps vs kettles

An increasingly popular (and rather expensive) option is to install a boiling water tap and do away with your kettle altogether.

These taps dispense near-boiling water at the touch of a button. They’re a good way to streamline your kitchen surfaces, and some are claimed to save energy as you’ll never have to pay to heat more water than you need.

However, we’ve found that the savings aren’t all they seem. While convenient and stylish, boiling water taps are expensive to buy and often have ongoing maintenance costs that outweigh any potential energy savings. 

Find out more about the pros and cons, and how the different brands compare, see our guide to the best boiling water taps. 

Which kettle brand is the most reliable?

Kettles are one of the most unreliable household gadgets you can buy. More than one in five will break down in the first two years, but some brands have a better track record for reliability than others. 

Regularly descaling your kettle will help it to last longer, particularly if you live in a hard-water area. Read our guide on how to remove limescale from your kettle for advice.
