Which blender brand is the most reliable?

We've investigated the performance and reliability of some of the most popular blender brands including Braun, Kenwood, KitchenAid, Ninja and NutriBullet.

For our unique small appliance survey, we ask more than 2,586 blender owners in the UK if they're happy with their blender and if they've run into any problems, so you can see which brands are worth spending your money on.

Damaged power cables, broken blades and cups accounted for the most common faults, but which brands steered clear of these and came up trumps?

The three most common blender faults

1. Broken or damaged power cable (31% of all faults reported)

With a damaged power cable, your options for repair are slim. In the first instance, check your warranty to see whether you are entitled to a free repair or replacement.

Of all the brands that appear in our survey, Breville owners encountered the issue of broken or damaged cables the most often. The brand's instruction booklets outline that if a blender cord is damaged 'it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard'.

2. Broken blade (29%)

Blender manuals should offer maintenance advice to help you avoid damaging your blender blade. But if it does happen, manufacturers should provide or sell replacement parts. 

Some manufacturers suggest replacing the blade after a set amount of time, regardless of whether it’s faulty or not, because they tend to become blunt.

3. Blending jug or cup broke (27%)

While frustrating and annoying, this is one issue that's really simple to fix. Check online or call the manufacturer about spare parts. 

Is it possible to repair a blender?

Some blender problems such as broken blades and broken gaskets can be easily fixed with spare parts, especially where the blender has a modular design with components that can be easily removed. A more catastrophic failure like a broken motor or a damaged power cable will be much harder to fix.

• Broken blades It's likely that the blade of your blender will be detachable. You'll need a replacement blade that matches the model of your blender, so search online for appliance stores or contact the manufacturer of your blender. 
• Broken gaskets Eroded gaskets around the blade or the lid of the blender can cause leaking or other failures because a gasket keeps components of the blender sealed tightly together. You'll need a replacement gasket that is the exact same size as the old one, so you'll want to check the manufacturer's recommendation and look for compatible parts online. If the seal is wrapped around the blade, some manufacturers might require you to buy a whole new blade.

Which blender brands offer the best guarantees?

Most blender brands offer product guarantees of two years as standard. However, others such as the brands below have exclusions and extensions. Always read the fine print.

• Magimix The motors of Magimix blenders are guaranteed for an impressive 30 years, which includes the stator, rotor, bushings, relay and capacitor. Parts are also guaranteed for three years against manufacturing faults. 
• Ninja For blenders purchased up to 31 December 2022, your guarantee is only one year. However, this extends to two years for blenders purchased on and after 1 January 2023.
• NutriBullet Typically you will get a one-year warranty with any NutriBullet blender, but you can get some models offering a few more years.

How we discover the most reliable brands

Which? has a wealth of information on the UK's favourite appliance brands. Every year we ask Which? members to tell us about the home appliances they own – from how likely they would be to recommend a brand, to how reliable the products are once they get them home.

This year more than 10,718 Which? Connect Panel members and members of the public told us about more than 30,000 individual products, including over 2,500 blenders. We calculate each brand's customer score, fault rate and reliability rating using the results of our annual survey.

Our surveys, combined with our extensive lab tests, mean we can recommend the best blenders you should buy.
