If you’re into making smoothies and milkshakes or love homemade soup, a blender is a nifty and useful addition to your kitchen – the best blenders can blitz your ingredients to a smooth consistency in seconds.

But do you need a traditional jug blender or would a mini blender such as the NutriBullet suit you better? And what features are really useful to have?

In this expert guide, we tell you what to look for when you begin your jug blender hunt, and how much you'll need to spend to get a decent one.

Just want to know which blenders are best? Go straight to our in-depth blender reviews.

Is it worth buying a cheap blender?

Preparing veg for blender

Most blenders cost between £30 and £150, but there are some super-premium 'professional-grade' blenders from brands such as Blendtec, Sage and Vitamix that cost significantly more – sometimes more than £500.

Super-premium blenders claim to tackle many more food preparation tasks, such as milling grains, making nut milk, heating soup and chopping veg. Some also have lengthy guarantees and claim to be more durable than cheap blenders.

The good news is that you don't have to spend a lot to get hold of a brilliant blender – if you're willing to skip extra features and attachments, then you can snag a decent blender for under £40. And some pricier blenders have disappointed in our tests, so it's worth checking our reviews before forking out for a premium model.

We've found that more power doesn't always equal better blending, but if you want features such as interactivity with your phone or tablet, extra blades/jugs for different food preparation jobs, or a long guarantee, you'll need to pay more.

You don't need to spend a fortune to get a good blender - see our Best Buy blenders.

NutriBullet blender – should I buy one?

If you're in the market for a blender, chances are you've considered a NutriBullet. Since the original NutriBullet 600, there have been a lot of NutriBullet blenders to choose from. Older NutriBullet blenders are cheaper mini models, while new ones have features like smart connectivity and bigger capacities. 

NutriBullet became famous because of its line of mini blenders, though in 2020 it started releasing jug blenders too. We've reviewed a lot of NutriBullet blender products – some are great, and others underwhelmed us. You can see how all five NutriBullet blenders scored in Which? lab tests by heading to our NutriBullet reviews.

Should I get a juicer or smoothie maker instead?

Smoothie makers are similar to jug blenders, except that they have a dispensing tap so you can pour your smoothie straight from the jug into your glass.

They're no longer widely available. If you're looking for a convenient and speedy smoothie maker, a mini blender such as the NutriBullet may be a better choice, as we've found that the taps on smoothie makers tend to clog easily.

Confusingly, some blenders also describe themselves as juicers. Juicers extract juice from fruit and veg, leaving you with a thin, clear drink, and pile of waste pulp. Blenders blitz all the fruit and veg together, forming a thicker mixture with no waste pulp. 

Our expert guide to choosing a jug blender, juicer or smoothie maker explains the pros and cons of each in more detail.

Do I need a soup maker or a blender?

In our tests, lots of blenders do a good job of blending soup. But transferring soup from the pan to the blender and back can be messy and time-consuming, especially if you're making a big batch.

If you mostly want to make soup, it's worth considering a soup maker. These have a heating element at the bottom of the jug, which means you can blend and cook your soup all in the same appliance. They usually also have a smoothie setting, so you might not need to get a blender as well.

Head to our in-depth soup maker reviews to find out which ones make the best soup with minimum fuss.

Should I go for a vacuum blender?

Vacuum blending is a recent trend in newer, more expensive blenders that take air out of the jug or cup before blending. It's often claimed that this produces brighter, more flavoursome smoothies with fewer bubbles and less foam on top, and that the smoothie should separate out into layers less over time. 

Bigger claims can even include that smoothies will stay fresh for longer and retain more of the nutrients of the original ingredients. With ordinary blenders, the high-speed blending action can introduce lots of air into the mix. So, in theory, the lack of oxygen in the blending jug would help to prevent the smoothie oxidising – in the same way that avocados or apples go brown – by preventing enzymes from undergoing a chemical reaction that creates melanin. The lack of oxygen is also said to help to stop water-soluble vitamins, such as B-complex vitamins and vitamin C, from oxidising, helping to preserve the amount of each in your smoothie.

In our vacuum blending try-out, we found that vacuum blending produces a smoothie with fewer bubbles and less foam on top. But the smoothies we made weren't brighter or more flavoursome, and didn't have less separation. We kept them in the fridge for four days, and found that they didn't stay fresh for longer, either.

Useful blender features to look out for

Don't shop for a blender without using our checklist below to ensure you get a blender with the extra features you really need.

Blender jug Plastic is lighter but can absorb odours and get scratched over time. Glass jugs are sturdier and look more upmarket, but can be very heavy when full. You'll pay more for high-quality plastics such as BPA-free Tritan, which is extra strong, light and looks like glass, but offers the best of both worlds. 

Dishwasher-safe parts Washing up can be laborious, so look for a blender where the parts are dishwasher-safe. It's handy if the blade is removable, so it can be separated from the jug and thoroughly cleaned.

Mini blender cups Some jug blenders come with an extra smaller blending cup and lid as well as the standard blending container. Useful if you want to take your smoothie to work or the gym.

Speed settings Variable speeds give more blending control. Most blenders have at least two speeds, while some have programs designed for specific tasks, such as making milkshakes.

Ice crushing More advanced models sometimes have an ice crush setting for making cold smoothies or frozen drinks. If your blender isn’t suitable for crushing ice, it can blunt the blades.

Milling/grinding blade Some models will have an extra jug and blades for drier jobs, such as grinding coffee beans or nuts.

Tamper This is a stick used to safely push ingredients towards the blending blades when stuck. They're handy for thicker mixes such as instant ice-cream, but ideally the blender shouldn't need manual intervention to blend smoothly.

Jug blender lids Some models have a jug lid that incorporates a strainer that can filter out any remaining lumps when you pour. Many have removable inserts in the lid, which means you can add ingredients as you go along for precise blending jobs, such as when making homemade mayonnaise.

Cable storage Cable storage keeps the cable tidy when not in use, and some machines have plug storage too.

Smart connectivity This is when a blender can connect with your smartphone to unlock extra features. The only smart blender we've tested is the NutriBullet Balance, which the manufacturer claims will work with an app on your phone to analyse the nutritional content of your smoothie. 

Is it possible to repair a blender?

Blades on a blender

Our research shows that the most common blender faults are broken gaskets, broken blades, and burned-out motors. Some of these problems can be fixed with spare parts, especially when blenders have modular designs with components that can be easily removed. A more catastrophic failure like a broken motor 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 it's best to search online for appliance stores or contact the manufacturer of your blender. Some manufacturers recommend replacing the blade regularly as maintenance; for example, NutriBullet recommends buying a new blade every six months.
  • Broken gaskets Eroded gaskets around the blade or the lid of the blender can cause leaking or other failures because they are what keep 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. 

Should I buy a second-hand or ex-display blender?

You might be able to grab a better deal if you buy a second-hand or ex-display blender, which also cuts down on waste and does your pocket a favour. But there are a few things you should think about before buying one, particularly if it's previously been used:

  • A second-hand blender may require maintenance, particularly if the rubber seals are damaged or if the blade is blunt from use. It's easy to replace these parts, but if the motor is worn from misuse you won't know this until it breaks. 
  • Check whether the seller offers a guarantee on its appliances, particularly for third-party sellers on marketplaces such as Amazon and eBay. This will give you more security in case the electronics go wrong quickly, or in case there is a safety problem with the product. 
  • Vintage electrical products have been identified by Electrical Safety First as being a particular safety concern, with the potential to cause fires and/or electric shock. You should be especially cautious of a second-hand appliance with an original braided cable instead of a new PVC cable.

How should I dispose of or recycle my old blender?

According to Recycle Now, around one million tonnes of electrical and electronic waste are generated every year. Every item that has either a plug, a charger, batteries or carries a crossed-out wheelie bin logo can be recycled, and that includes blenders.

Broken appliances should be recycled:

  • Some shops, such as Currys, will collect and recycle old appliances when delivering new ones – check the store website for details. Many will also allow you to drop off smaller electrical appliances in-store for recycling.
  • Arrange for a bulky waste collection through your local council.
  • Take the appliance to your local council recycling/reuse centre.

Appliances that are still working can be reused. If your old blender is still working, donate it to charity (many offer collections), sell it, or take it to your local council recycling/reuse centre.

You can find your nearest recycling location (including stores and council sites) using Recycle Now’s recycling locator.
