Top kettle brands for 2021

Make sure your next kettle lasts for years by choosing one of the most hassle-free and best-loved brands from our member survey
Rebecca Jakeman
Making cup of tea

Faulty lids, problems switching on or off and limescale issues are the most common kettle faults according to our survey of 9,103 kettle owners in the UK.

You use your kettle every day, so you need to make sure that you won’t be left high and dry by an unreliable brand. That’s why, every two years, we survey thousands of Which? Connect Panel members to tell us whether or not they’re happy with their current kettle, as well as any problems they’ve experienced.

Our in-depth customer experience survey accounts for the main type of faults reported for each kettle brand and how quickly they occur after purchase.

We’ve collected data on the biggest kettle brands, including Russell Hobbs, Bosch, Dualit, Breville, DeLonghi and Kenwood. This means we can tell you which brands we recommend and which ones you’re better off avoiding.

  • Table notes: The customer satisfaction and fault-free after five years percentages are based on a survey of 9,103 Which? Connect Panel members who own kettles, conducted in May 2021. Table last updated 7 June 2021.
  • Customer satisfaction is based on whether owners would recommend the brand to a friend.
  • Average test score is based on Which? tested models (not including similar models) online in June 2021. n/a = not enough data.
  • Fault-free after five years shows which brands were least faulty over this period of time.

Best vs worst kettle brands

As the chart below shows, there is a huge difference between the brands with the highest and lowest customer satisfaction scores. 

The worst brand had an average customer satisfaction score of just 59%, compared with the 84% achieved by the best brand. 

Our figures also show that, while there isn't a huge difference between brands in the number of faults reported in the first five years of ownership, average test scores also reveal big disparities between brands.

How long will my kettle last?

The average kettle will last ten years. This is based on the experiences of Which? Connect Panel members who told us how long they kept their previous appliance before it needed to be replaced due to a fault.

There’s a noticeable difference between how long the best and worst brands last, but as you can see in the graph below, the majority of models will last at least nine years if you take care of them properly.

Verdict: kettle brands in depth

We’ve collected lots of data on average scores in our lab tests, customer happiness and estimated lifetime to supply an in-depth picture of well-known kettle brands.

The three most common kettle faults

Taking good care of your kettle – such as regularly cleaning out the limescale filter and using the correct mechanism to open the lid every time – could help you avoid falling victim to the three most common kettle faults.

1. Lid stops working properly (19%)

According to our recent survey of Which? members, the most common problem encountered in kettles is a faulty lid. This includes issues such as the lid failing to open, or even the lid popping open during the boiling process. You can prevent this from happening by never forcing the lid open or slamming it closed.

2. Limescale problems (12%)

Limescale problems are almost entirely preventable, yet they account for more than 10% of kettle faults. The most common limescale issues Which? members encountered were the filters and spouts becoming blocked with limescale, or a build-up of limescale inside their kettle leading to flaky deposits in their hot drinks. 

You can prolong the life of your kettle by cleaning it regularly. Head to our guide on how to descale a kettle for some handy hints and tips.

3. Problems with auto cut-off (12%)

Auto cut-off problems are classed as any issues involving the kettle switching on or off. This could be that it regularly cuts off during the boiling process, or that you’re unable to switch it off whatsoever. Not only is this dangerous, it will also result in higher energy bills for you.

How we calculate the best and worst kettle brands

Which? has a wealth of information on Britain’s favourite kettle brands. 

We regularly contact Which? Connect Panel members and ask them to tell us about the kitchen appliances they own, including whether or not they would recommend a brand, as well as how long the products last when they get them home. 

This year, more than 13,000 Which? Connect Panel members told us about more than 40,000 appliances, including over 9,000 kettles. Our survey, combined with our rigorous lab tests, means we can recommend the best kettle brands for you, as well as some you may want to avoid.
