Buying Guide
Capacity and family size
Air fryer capacity is measured in litres; 3–4 litres suits singles or couples, 4–6 litres is better for a family of three or four, and 6+ litres suits larger households or batch-cooking. Think about whether you want to cook a whole chicken or multiple portions at once - a larger capacity may mean a bigger footprint on your worktop.
Power and cooking performance
Wattage affects how quickly the fryer reaches temperature and how evenly it cooks - most models under £100 sit between 1,200–1,800W. Look for a model with a reliable temperature range (typically 80–200°C) and even heat distribution; user reviews are useful for spotting hot spots or uneven crisping.
Basket type and ease of cleaning
Decide between a drawer-style basket and a multi-tier or tray system - drawers with non-stick coatings are easiest for everyday cooking, while trays can be better for batches and reheating. Removable, dishwasher-safe parts and a non-stick interior vastly reduce maintenance time.
Controls, presets and build quality
Simple rotary dials are robust and cheap, while digital models offer precise temperature control and presets for chips, fish, or vegetables. Check build quality, warranties and whether replacement parts (like baskets) are available - these influence longevity and value.
Size, storage and kitchen layout
Measure the space where the air fryer will live; taller models may not fit under wall cupboards and larger units can be heavy to move. Consider storage if you won’t leave it on the worktop - some designs stack or have slimmer footprints that suit smaller UK kitchens.
Frequently Asked Questions
What is the best air fryer in 2026 under £100?
There’s no single best model for everyone, but in 2026 look for brands that combine at least a 3.5–4.5L capacity, solid 1,400–1,800W performance, dishwasher-safe parts and reliable after-sales support. Popular choices under £100 in the UK often come from Cosori, Tower and Instant (Vortex); check current reviews and retailer listings at Argos, Currys or Amazon UK for up-to-date prices.
Is an air fryer worth buying in the UK?
Yes - air fryers offer faster cooking and use less oil than deep-frying, which saves time and can be healthier. They’re especially handy in small UK kitchens and for quick midweek meals, though they’re not a complete replacement for an oven for very large dishes.
Which air fryer offers the best value for money?
Best value balances capacity, build quality and features rather than just the lowest price. Models around 3.5–5L with digital controls, a decent wattage and dishwasher-safe baskets often represent the best value for most households under £100.
Ninja vs Cosori – which should I buy?
Ninja tends to focus on robust build and higher-end features, while Cosori models often hit a sweet spot of easy-to-use presets and compact designs at lower prices. If your budget is strictly under £100, Cosori and mid-range Tower or Instant models are more commonly available; choose Ninja if a specific model with the features you want is discounted into your price range.
Can I cook a roast dinner in an air fryer?
You can cook smaller roast joints and whole chickens in larger air fryers (5–7L+), and they crisp well; however, space is limited compared with a conventional oven. For larger families or big joints, the oven remains more practical.
How much electricity does an air fryer use in the UK?
Air fryers typically draw 1.2–1.8 kW when running, so a 30–40 minute cook might use around 0.6–1.2 kWh. That’s often cheaper than using a full-size electric oven for the same task, but actual costs depend on your electricity tariff.
Where can I buy reliable air fryers under £100 in the UK?
Major retailers like Argos, Currys, John Lewis and Amazon UK frequently stock reputable models under £100, often during sales. Read customer reviews, check warranty terms and compare delivery/collection options to find the best deal.
What is the best air fryer for a small flat in 2026?
For a small flat, a 3.5–4.5L air fryer such as the Cosori 3.5L offers a compact footprint, low counter height and user-friendly presets; its basket design and dishwasher-safe parts make cleaning easy and it typically draws around 1,400W, balancing speed with energy use.
Is buying an air fryer under £100 worth it in 2026?
Yes - good budget air fryers in 2026 commonly provide solid 1,200–1,800W performance, reliable temperature control and dishwasher-safe baskets, delivering fast, oil‑light cooking that suits everyday meals; just prioritise capacity and build quality when choosing.
COSORI 3.5L vs Instant Vortex 4L – which should I buy?
Choose the Cosori 3.5L if you need a compact model with intuitive presets and a slim footprint; pick the Instant Vortex 4L for slightly greater capacity and a simple interface if you often batch-cook for two to three people. Both typically feature non-stick baskets and similar wattage, so base the decision on capacity needs and available counter space.
Which air fryer under £100 is best value for money in the UK?
Models that combine around 3.5–5L capacity, 1,400–1,800W power, digital controls and dishwasher-safe components typically deliver the best value; brands such as Cosori, Tower and Instant (Vortex) regularly offer these specs in the sub-£100 range at UK retailers like Argos and Amazon UK.
