Top blender brands for 2021

Leaks, broken blades and burnt-out motors accounted for most common faults according to our survey of 1,995 blender owners in the UK.

Blitzing solids into liquids can be an arduous task for blenders, especially when they’re in daily use over several years. That’s why we run a biannual survey to tell us whether or not owners are happy with the brands they invested in and what problems they've run into.

Our in-depth customer experience survey spells out the most common faults reported for blender brands and how often they occur after purchase.

We’ve collected information on household brands such as Bosch, Kenwood, Ninja and Nutribullet. We’ve cross referenced member satisfaction with independent lab results to provide you with a picture of which brands to invest in and which ones to avoid.

The three most common blender faults

1. Blade broke (20%) 

According to our survey of Which? Connect panel members, the most common problem encountered in blenders is the blade breaking or malfunctioning. Manufacturers should provide or sell replacement parts as well as maintenance advice that helps you to avoid damaging the component.

Some manufacturers suggest replacing the blade after a set amount of time regardless of whether it’s faulty or not because it blunts over time. 

2. Blender leaked (17%)

Blenders can leak when the rubber gasket erodes or breaks, or if there’s a fault with the lid. Like blades, rubber gaskets erode over time which makes it necessary to replace the part as maintenance. 

3. Motor burnt out (15%)

This is a more catastrophic fault where the blender can’t be fixed by swapping a single component. It’s often caused by wear and tear over time, but this accelerates if the motor’s used in extended bursts. Manufacturers will advise how long you can run a blender for continuously, and for longer periods of time it can be wise to use the 'pulse' function, which only engages the motor when a button is pressed down, so you can use it in bursts.

How we calculate the best and worst blender brands

Which? has a wealth of information on Britain’s favourite 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 1,995 blenders. Our survey, combined with our rigorous lab tests, means we can recommend the best blender brands for you, as well as some you may want to avoid.
