Get up to £50 cashback to upgrade to a brand-new model from Ninja

Your next kitchen upgrade could be much more affordable. For a limited time, send an old air fryer to Ninja, and the popular gadget brand will slash £50 off the cost of a brand-new air fryer, air grill, or multicooker.

You don't need to trade-in a Ninja-branded item, it can be from any manufacturer to unlock the discount.


The best part? You can combine this trade-in discount with any of the deals and discounts available from Ninja today. The US brand is offering up to £70 off its bestselling air fryers, including the newest dual-stacked model.

The term "air fryer" is somewhat misleading, as these clever kitchen gadgets aren't only about crisping-up homemade chips with 75% less fat than a traditional deep-fat fryer.

The trade-in discount from Ninja's UK website is only available until July 29. To be eligible for the £50 cashback, these are the steps you'll need to follow:

  1. Purchase an eligible product before July 29 on Ninja's online store 
  2. Submit your online claim to trade-in your existing air fryer within 30 days of that purchase date
  3. Once Ninja approves your claim and informs you via email, you'll receive instructions to send out your qualifying product
  4. After Ninja receives your trade-in product, you'll be sent your cashback

If you haven't heard of Ninja before, this US manufacturer was named the UK's number-one air fryer brand last year.

Owned by parent company SharkNinja, the Massachusetts-based firm is also known for its Dyson-rivalling cordless vacuum cleaners, hairdryers, and haircare products under the Shark brand. Research suggests between 30% (Leatherhead Food Research) to 46% (Iceland customer survey) of Britons currently own an air fryer. If you're already converted on the faster cooking speeds, lower energy bills... but would like a newer model, or larger capacity, this latest trade-in promotion from Ninja could be a great opportunity.

The most affordable model is the Ninja Air Fryer Max Pro, with its single 6.2-litre drawer to roast, bake, and air fry. It ships in a stylish Black and Copper colourway, and Amazon will even bundle a pair of silicon tongs, so you can remove food safely once it's cooked. This model earned a Recommended award from the team at TrustedReviews and clinched five-stars in a review from Ideal Homes.

Usually £149.99, this air fryer has now dropped down to £129.99 — plus any savings from your trade-in too.

This model boasts a 6.2-litre drawer, which is large enough to fit up to four chicken breasts. With cooking modes like Roast, Bake, and Air Fry, Ninja says its clever gadget can cook 50% faster than a fan oven and uses 60% less energy.

Ninja Air Fryer MAX Pro
$149.99 $129.99

The Ninja MAX Dual Zone Digital Air Fryer has two dishwasher-safe drawers with a 4.75-litre capacity — for a total of 9.5-litre. That's big enough to cook a 2kg whole chicken or 1.4kg of fries in each drawer. As such, this Ninja Foodi Max model should be more than enough for larger families to cook an entire meal without switching on an oven.

Normally £229.99, this air fryer has now dropped down to £159.99 — plus any savings from your trade-in too.

If you're looking for something a little bigger, this flagship dual-drawer model from Ninja is the best option. It boasts two vast 4.75-litre drawers for a total capacity of 9.5 litres. Ninja says that's enough to cook a 2kg whole chicken or 1.4kg of fries in each drawer without using your oven. You can synchronise both drawers to finish cooking at the same time, and set them individually to different temperatures

If you don't have the spare work surface to accommodate one of the large-capacity models above, the Ninja Double Stack XL Air Fryer could be the solution. In a world first, this clever model stacks the two drawers on-top of one another — minimising the amount of room required.

Ninja says its designers have managed to reduce the overall width by 30% compared to the dual-drawer Ninja Foodi Max. Despite this slimmer profile, the Ninja Double Stack XL Air Fryer has the same total 9.5 litre capacity, so you'll be able to cook the same amount of food. Based on research conducted by Ninja, this model is capable of cooking enough food to feed eight people in a single session.

Unveiled earlier this year, the Ninja Double Stack XL brings the vast capacity of the dual-drawer Foodi Max but squeezes it into a footprint much closer to the standard single-drawer Ninja air fryer models. If you're short on countertop space in your kitchen, this could be a worthy investment to forgo your oven and cook food faster and using much less energy
