Air Fryers UK: Capacity, Running Costs & Price-Comparison Guide (2026)
Choose an air fryer around the meals you cook, not the largest litre figure on a sale card. Basket shape, the size of each drawer and access for cleaning can matter as much as headline capacity. A model that needs several batches for your usual meal may be less convenient than a larger oven, while a compact appliance can be useful for smaller portions.
This guide compares appliance layouts and buying checks. It does not claim that Tailored Deals has tested every model or that one appliance will always reduce your bill. Catalogue offers below are separate from the advice and can change. Use the retailer’s current model specification, the manufacturer’s instructions and your own electricity tariff when deciding what represents value.
Compare the options
Use these criteria to compare the product or service types with your own requirements.
| Layout | Capacity check | Useful for | Trade-off | Space to measure |
|---|---|---|---|---|
| Compact single basket | Usable floor area and recommended food load | Small batches and limited worktop space | A complete meal may need repeated batches | Handle projection and rear ventilation clearance |
| Large single basket | Whether a usual dish fits flat | One larger batch or a wider cooking dish | One temperature zone at a time | Drawer opening distance |
| Dual drawer | Capacity of each drawer, not only the total | Foods with separate cooking settings | Each drawer may be narrow | Full width with both drawers removed |
| Flexible divided basket | Usable space with and without divider | Changing between one large and two small zones | Divider and settings differ by model | Storage for removable parts |
| Oven-style air fryer | Tray dimensions, shelf positions and rated load | Tray-based cooking and different shapes | More surfaces and accessories to clean | Door opening space and overhead clearance |
Translate capacity into the meals you actually make
The total litres stated on a box are not a standard promise about how many people an appliance feeds. A deep drawer and a broad shallow drawer can have similar volume but hold food differently. Start with a typical meal: the amount of chicken, vegetables or potatoes you normally cook, and whether those items need separate settings. Check the manufacturer’s recommended load for that recipe or food.
If you use an oven dish, measure its outside dimensions including handles. Compare those with the basket’s usable internal dimensions rather than the appliance width. Allow the space required by the instructions for circulation and safe handling. Do not plan around filling a drawer to the top merely because the food physically fits; crowding can change how evenly it cooks.
For a two-drawer appliance, write down the capacity of each compartment. A combined capacity can conceal two relatively small cooking areas. Check whether both drawers can operate independently, whether they can finish together and what happens when both use high-power settings. Those details vary between models, so look for the exact manual rather than assuming all dual-drawer products behave alike.
Estimate running cost without treating the estimate as a test result
A simple calculation is power in kilowatts multiplied by hours of operation multiplied by your electricity unit price. For an illustrative 1.5 kW appliance running continuously for 20 minutes at an assumed 30 pence per kWh, the calculation is 1.5 × (20 ÷ 60) × 30 = 15 pence. The 30 pence rate is an example, not a statement about today’s tariff or a forecast.
Actual consumption can differ because heating elements cycle, settings change and preheating or extra batches take time. Nameplate power describes rated power rather than an independently measured cost per meal. If you want to compare your own appliances, use a suitable electricity monitor according to its rating and instructions, and compare the same quantity of food cooked to the same safe result.
Energy Saving Trust explains that the choice of appliance and the portion being cooked affect energy use. A small appliance can make sense for a small meal, while using the oven’s space efficiently may be more suitable for a larger batch. Include the cost of buying the new appliance in your decision. A possible saving on occasional meals does not automatically justify replacing equipment that already meets your needs.
Check the worktop, controls and handling
Measure the place where the appliance will actually be used, including the space behind and above it required by the manual. Leave room to pull out a hot drawer and set it down safely on a suitable surface. A product may fit under a cupboard when stored but need to move before cooking. Think about whether you are comfortable lifting and moving it repeatedly.
Look at the controls in a clear photograph or a shop demonstration. Check display contrast, the size of labels and whether basic time and temperature settings are easy to change. An app is not a substitute for accessible physical controls. If connected features are important to you, read the compatibility requirements and find out whether the appliance remains useful without an account or network connection.
Consider the weight and grip of a loaded basket, not just the empty appliance. A large drawer can be awkward to carry to the sink. Compare the position of the release mechanism, whether an inner basket detaches and how the manufacturer says to handle hot parts. These practical checks can matter every day even though they rarely feature in a promotional headline.
Make cleaning and replacement parts part of the comparison
Read which parts are removable and which, if any, the manufacturer permits in a dishwasher. Do not treat the entire appliance as dishwasher-safe because one accessory is. Check the cleaning method for the coating and whether the heating area is accessible for routine care. If a manual is unavailable before purchase, ask the retailer for the exact model’s instructions.
Price a replacement drawer, crisper plate or basket if the manufacturer sells them. Availability does not guarantee future supply, but it helps you judge the current support arrangements. Find out who handles the warranty and whether the seller is an authorised stockist. For refurbished or open-box stock, check the condition, included accessories and whether warranty terms differ from new stock.
Accessories also change the total spend. Only use liners, racks or dishes the manufacturer says are suitable for the appliance and setting. Avoid assuming that a generic accessory will fit because its description mentions air fryers. Compare bundles on the accessories you expect to use rather than counting every included piece as a saving.
Follow food and appliance instructions together
The Food Standards Agency advises following food and recipe cooking instructions and checking that food is cooked thoroughly. Air-fryer settings can vary, and a browned surface does not establish the temperature throughout a thick item. The agency describes using a clean food thermometer and suitable visual checks. Consult its full guidance for the food you are preparing, including reheating and avoiding cross-contamination.
The FSA also notes that space around food can matter in appliances such as air fryers. Use the appliance manual for loading, ventilation and suitable cookware. Do not transfer an oven time mechanically to a different appliance and assume the result is safe. When a packet does not provide air-fryer instructions, seek appropriate cooking guidance instead of relying on a promotional recipe image.
These checks are buying considerations too. If you often cook several foods together, ask whether the layout lets you manage their different cooking needs. If cleaning a drawer or checking the centre of a large item would be difficult, a different format may be easier. Choose the workflow you can use consistently rather than the largest number of preset buttons.
Compare the exact model and complete delivered price
Record the model number, colour, plug, included accessories and warranty. Similar product names can cover older and newer generations with different baskets or controls. Confirm that the listing is intended for the UK market and check who the seller is, especially on a marketplace. A familiar platform name does not mean the platform itself supplies the product.
Compare the delivered price after the voucher has been accepted, including any minimum-spend condition. If a retailer advertises a saving against an RRP, keep that separate from a verified previous selling price or a comparison with another shop. A percentage alone does not establish the cheapest available deal. Save the terms and confirmation for any cashback or promotional accessory you intend to claim.
Give yourself a decision rule: buy only when the appliance meets your meal, space and cleaning requirements at a price within your budget. A countdown or limited-stock message should not replace those checks. If none of the current listings fit, keep the shortlist and revisit it. Continuing to use an existing oven or microwave may be the sensible choice while you compare.

Questions before you buy
How many litres do I need for a family?
There is no universal litres-per-person rule. Compare the manufacturer’s suggested food loads and usable basket area with the amount you actually cook. A dual-drawer total should be considered as two separate spaces, and a meal may need more than one batch.
Is an air fryer always cheaper to run than an oven?
No. Portion size, cooking time, appliance behaviour and how efficiently you fill an oven all affect the result. Use a measured comparison for the same meal where possible. The worked example above is arithmetic using assumed inputs, not a tested appliance result.
Should I pay more for a connected model?
Only if the connected feature solves a task you value. Check whether core controls work without the app, which phone versions are supported and what account or connectivity is required. Compare cooking layout and cleaning access before paying for optional software features.
Does a feed price drop prove a genuine historical saving?
No. It can show a lower listed price relative to a supplied comparison value. A historical was-price claim needs appropriate evidence of the previous selling price. Check the basis of the comparison and the retailer’s final checkout amount.
