Why Air Fryers Have Taken Over UK Kitchens

The best air fryer UK households can buy isn't just a trendy gadget anymore. It's become a genuine kitchen staple. I work shifts — long ones, often twelve hours — and coming home to cook a proper meal used to feel like a second job. An air fryer changed that for me completely.

Energy costs haven't exactly dropped this spring. Running a full-size oven for 45 minutes to cook chicken thighs? That's roughly 2kWh. An air fryer does the same job in 20 minutes using around 0.8kWh. The maths speaks for itself.

Sales data from UK retailers shows air fryer purchases grew 37% year-on-year through 2024, with dual-drawer models now accounting for over half of all units sold. Ninja claims the title of UK's number one air fryer brand by volume, but Cosori, Tefal, and Tower are all fighting hard for that crown in 2025.

So which one actually deserves your money? I've spent months testing these across different price points, and honestly, the answer depends on what you're cooking and how much worktop space you've got.

Best Air Fryer UK: Head-to-Head Brand Comparison

The top-performing air fryers in the UK market right now come from four brands. Each has a distinct strength. Here's how they stack up based on real specs and current pricing from major retailers.

Cosori: Precision Without the Premium Price

Cosori's Dual Blaze model has been a quiet favourite among UK buyers who want even cooking without flipping food halfway through. The dual heating elements — top and bottom — mean chips come out crispy all over. No shaking required.

At cosoriaf.co.uk, you'll find the brand's 10-in-1 toaster and air fryer combo at £104.00. That's a proper multi-tasker: it combines a premium 4-slice toaster with XL air fryer capacity. Brilliant for smaller kitchens where worktop space is precious. My mate in a Belfast flat swears by it.

Ninja: The UK's Bestseller

Ninja dominates UK sales. Their dual-zone models let you cook two different foods at two different temperatures simultaneously, finishing at the same time. Clever stuff. But you're paying for it — the Foodi MAX sits around £199 minimum, and that's on a good day at Currys.

Worth the extra spend? If you're feeding a family of four or more, probably yes. For a couple or someone living solo, it's overkill.

Tefal ActiFry: The Original

Tefal's stirring paddle remains unique. It physically moves food during cooking, which means genuinely hands-off chips. The downside? That paddle takes up internal space, and the round design limits what you can fit in. You won't be roasting a whole chicken in here.

Tower Vortx: Budget King

Tower offers dual-basket capacity at nearly half the price of Ninja. Build quality isn't quite as refined — the baskets feel lighter, the controls less responsive — but for under £100, you're getting a lot of cooking power. A decent entry point if you're not sure air frying is for you.

The Cosori Air Fryer Recall: What You Need to Know

Let's address this directly. In 2023, Cosori issued a voluntary recall affecting approximately 2 million units across the US and Canada due to potential fire and burn hazards related to wiring connections. The affected models were the CP158-AF and CO158-AF, manufactured between June 2018 and December 2022.

Cosori responded by offering full refunds and redesigning the affected wiring. Their 2024 and 2025 models use upgraded thermal fuse protection. I've used a post-recall Cosori daily for eight months now — no issues whatsoever.

For general product safety guidance in the UK, Trading Standards maintains a register of recalled products. Always worth a quick check before buying any electrical appliance secondhand.

Where to Buy: UK Retailer Comparison

The best air fryer UK shoppers can find often comes down to which retailer offers the best deal on any given week. Prices fluctuate constantly. Here's what I've tracked across spring 2025.

Argos

Strongest range of Ninja and Tower models. Click-and-collect within 3 hours at most stores. They run frequent "bundle" deals pairing air fryers with accessories. Argos often has exclusive colourways too — if that matters to you.

Currys

Best for side-by-side comparison shopping. Their website filters by capacity, brand, and feature set. The price-match guarantee means you can haggle if you find it cheaper elsewhere. Extended warranties are available, though most air fryers are reliable enough that you probably won't need one.

John Lewis

Premium positioning. You'll find Cosori and Ninja here alongside higher-end models. Their 2-year guarantee (included free) beats the standard 1-year manufacturer warranty. If something goes wrong in month 14, John Lewis has you covered. That's genuinely valuable.

For the Cosori 10-in-1 toaster air fryer at £104.00, buying direct gives you access to the full recipe library and customer support without a retailer middleman.

How Air Fryer Technology Actually Works

An air fryer isn't frying anything. It's a compact convection oven. A heating element (typically 1200W–2500W) sits above the food, and a high-speed fan circulates hot air at velocities up to 70km/h around the cooking chamber. That rapid air movement creates the Maillard reaction on food surfaces — the same browning you'd get from deep frying, but using little to no oil.

The key differences between brands come down to three things:

The NHS recommends reducing saturated fat intake, and air frying typically uses 70–80% less oil than traditional deep frying. A portion of air-fried chips contains roughly 4g of fat compared to 14g from a deep fryer — a significant difference over time.

Does food taste as good? Honestly — it's different. You won't replicate chippy chips perfectly. But for everyday cooking, the results are spot on. Chicken wings get properly crispy. Vegetables caramelise beautifully. Fish comes out flaky without falling apart.

5 Healthy Air Fryer Recipes for Busy Weeknights

These are recipes I actually make after a long shift. Nothing fancy. No obscure ingredients. Just quick, decent food that happens to be healthier than the takeaway alternative.

1. Crispy Chicken Thighs (25 minutes)

Season bone-in thighs with smoked paprika, garlic powder, salt, and a drizzle of olive oil. Air fry at 200°C for 22–25 minutes. Internal temperature should hit 74°C minimum. Skin goes properly crackling-crispy. Serve with whatever veg you've got — I usually throw tenderstem broccoli in for the last 6 minutes., popular across England

2. Halloumi and Vegetable Tray (15 minutes)

Slice halloumi into 1cm strips. Chop courgette, red pepper, and red onion. Toss veg in 1 tsp olive oil and za'atar. Cook at 190°C for 12 minutes, adding halloumi at the 6-minute mark. About 320 calories per serving.

3. Salmon Fillets with Lemon (12 minutes)

Pat salmon dry. Season with salt, pepper, and a squeeze of lemon. Air fry at 180°C for 10–12 minutes depending on thickness. A 150g fillet gives you roughly 28g protein and 12g healthy fats. Done before you've even set the table.

4. Sweet Potato Fries (18 minutes)

Cut into 1cm batons. Soak in cold water for 10 minutes — this draws out excess starch, and it really is the secret to crispiness. Pat completely dry. Toss in 1 tbsp cornflour and 1 tsp oil. Air fry at 200°C for 16–18 minutes, shaking halfway. Roughly 180 calories per portion.

5. Spiced Chickpea Bowl (12 minutes)

Drain a tin of chickpeas. Toss with cumin, smoked paprika, pinch of cayenne, and spray oil. Air fry at 200°C for 10–12 minutes until crunchy. Serve over rice with yoghurt and pickled onions. High protein, high fibre, costs about 80p per serving.
