Best air fryers for UK kitchens

How we chose the shortlist

An air fryer should be judged as a small fan oven with a particular basket arrangement, not as a magic replacement for every appliance. We prioritised models that represent genuinely different ways to organise a family meal. The Ninja AF400UK uses two equal 4.75-litre drawers, which is easy to understand and flexible when cooking two large foods. The Ninja SL400UK stacks its zones vertically to reduce width. The Philips NA352/00 uses unequal drawers, giving the main course more space than the side. These layouts create clearer buying differences than minor changes in preset names.

The shortlist also considers controls, cleaning and ownership. Synchronised finishing is valuable because it lets foods with different temperatures and cooking times complete together. Removable drawers and crisper plates need to be practical to wash, and the appliance must fit with clearance for vents and drawer removal. We have not ranked products by affiliate commission or a temporary sale price. Availability, colours and bundled accessories can change, so buyers should verify the exact UK model code before ordering.

Usable capacity matters more than the number on the box

Combined litres are a useful starting point, but they do not tell you how much food can cook well at once. Air frying relies on hot air reaching the food, so a crowded deep pile may need more shaking and can brown less evenly than a shallower layer. Wide drawers are useful for items such as fish fillets, chops, burgers and vegetables. Deeper baskets can hold a large quantity of chips or smaller pieces, but the food may need turning or shaking during cooking. Think about the shape of your usual meals rather than choosing the highest capacity figure.

For a family of four, a large dual-zone model is often convenient because it separates a main and side or allows two dietary requirements to be cooked independently. It does not guarantee that every complete meal will fit. A whole chicken, a large tray of vegetables or bulky breaded foods may use most of one zone. When comparing models, look at individual basket dimensions, not only combined capacity. Measuring a dinner plate, baking dish or the food packets you regularly buy can be more informative than comparing litre claims.

Side-by-side, stacked or unequal drawers

Equal side-by-side drawers are the safest general-purpose choice. They are easy to load, both zones are at the same height and either side can take the larger part of a meal. The drawback is width: a substantial twin-drawer appliance can dominate a small worktop and may leave too little preparation space. It also needs room in front for both drawers to open fully. The AF400UK therefore makes most sense where the worktop can accommodate a wide permanent appliance.

A stacked model trades width for height. The SL400UK is appealing in a narrow kitchen, but buyers must check the distance to wall cupboards and the convenience of reaching the lower drawer. Multi-level racks can increase cooking flexibility, although food position and airflow become more important. Unequal drawers, as used by the Philips NA352/00, suit households that usually cook a large main with a smaller accompaniment. They are less convenient when two equal batches are the norm. The best arrangement is the one that matches repeated meals, not the most unusual design.

Controls should reduce work rather than add options

The most useful dual-zone feature is synchronised finishing. It allows one drawer to cook at a different temperature or for a different duration while both finish together. A matching function is also helpful when using the same programme across both zones. Beyond that, a long list of presets is less important than clear temperature and time adjustment. Most owners settle into a small number of manual settings once they learn how their preferred foods behave.

Check whether settings can be changed without cancelling the whole programme, whether the display is readable from your normal standing position and whether reminders to shake or turn food are useful rather than intrusive. Published cooking tables are starting points, because portion size, food temperature and basket loading affect results. A good air fryer should make ordinary meals easier after a short learning period. If every recipe requires racks, multiple accessories and frequent rearrangement, the extra theoretical capacity may not translate into simpler cooking.

Worktop fit, ventilation and everyday handling

Measure the complete operating space, not just the appliance body. Include the handle depth, room to remove hot drawers, space around ventilation outlets and clearance beneath wall cupboards. A stacked machine may solve a width problem while creating a height problem. A side-by-side model may technically fit but leave no safe landing area for a hot drawer. The power lead also needs to reach a suitable socket without an extension arrangement that conflicts with the manufacturer instructions.

Consider weight and storage honestly. Large dual-zone air fryers are often treated as permanent worktop appliances because moving them in and out of a cupboard is inconvenient. If the machine will remain visible, dimensions, cable routing and the way it sits beside other appliances matter. Handles should feel secure when a drawer is full, and controls should be reachable without leaning over steam or hot vents. Households with children should think about where hot drawers will be placed and keep the appliance away from worktop edges.

Cleaning, running cost and long-term value

Dishwasher-safe parts are useful, but a large drawer can occupy much of a dishwasher rack. Hand washing may be quicker if the sink is large enough and food is not allowed to dry onto the coating. Check the instructions before using abrasive pads, metal utensils or aggressive cleaners, because damage to a non-stick surface can shorten the useful life of the basket. Removable crisper plates should lift out easily without spilling grease, and the area around the heating element should be maintained only as directed by the manufacturer.

Air fryers can be efficient for small portions because they heat a compact chamber, but savings depend on what they replace, the quantity cooked and the time used. A large air fryer running several consecutive batches may not be the cheapest or fastest approach to a full oven-sized meal. Value therefore comes from frequent suitable use, not simply owning the largest model. Budget for liners or accessories only when they improve your routine; badly fitted liners can obstruct airflow, and extra racks create more cleaning.

What to consider before buying

• Measure width, height, depth and cupboard clearance before buying.
• Compare individual drawer dimensions as well as combined litre capacity.
• Choose equal drawers for two substantial foods and unequal drawers for a larger main with a smaller side.
• Prioritise synchronised finishing over a long list of preset names.
• Check where hot drawers will be placed when removed.
• Confirm removable parts fit your sink or dishwasher.
• Follow the manufacturer guidance for ventilation, cleaning and electrical use.
• Verify the exact UK model code because colours and bundles can differ.

Frequently asked questions

What size air fryer is best for a family of four?

A dual-zone model with roughly 8 to 10 litres of combined capacity is a practical starting point for many families of four. Basket shape and individual zone dimensions matter as much as the total figure, especially for wide foods that need a single layer.

Is a dual-drawer air fryer better than a single basket?

A dual-drawer model is usually better for complete meals because two foods can use different settings and finish together. A large single basket can be better for one bulky item, a large tray-style portion or households that rarely cook two foods separately.

Do stacked air fryers cook as evenly as side-by-side models?

A stacked model can produce good results, but rack position, loading and turning may require more attention. Its main advantage is saving width. It should be chosen for room fit and workflow rather than an assumption that stacking improves cooking performance.

Are air-fryer drawers dishwasher safe?

Many removable drawers and crisper plates are described as dishwasher safe, including the AF400UK parts referenced by Ninja support. Always check the instructions for the exact model, because coatings and accessory guidance can differ.

Can an air fryer replace an oven?

It can replace an oven for many smaller meals, reheating tasks and foods that fit comfortably in the baskets. It is less suitable for large baking trays, several large dishes or anything that needs the full width and height of a conventional oven.

Should I buy liners for an air fryer?

Liners can simplify cleaning, but they must be heat-safe, correctly sized and used without blocking essential airflow. Follow the appliance instructions and avoid placing a loose lightweight liner in an empty preheating basket.
