A good air fryer uses as little as 1,300W compared to a conventional oven's 2,000W-plus, which adds up to real savings on your electricity bill. From a 2L compact for solo cooks to a 10.4L dual-zone for feeding the whole family, these eight models cover every UK kitchen and budget in 2026.
What to look for
01Wattage and running costs on UK 240V mains
Wattage is the single biggest factor in how much an air fryer costs to run. On the UK 240V mains supply, models in this guide range from 1,300W (Russell Hobbs 4.3L) up to around 2,400W for large dual-zone units. At a typical unit rate of 24p per kWh, a 1,300W fryer costs roughly 5p for a 15-minute cook, while a 2,400W model costs closer to 10p for the same session. That gap sounds small, but it compounds quickly if you cook daily. Smaller baskets tend to use less power because they heat a smaller cavity, so a 2L compact like the Chefman is genuinely cheaper to run per session than a 9.5L dual-zone, even if the larger model is more efficient per portion when cooking for four or more people. Always check the wattage on the product label, not just the listing title.
02Capacity and portion size
Capacity is measured in litres and directly affects how many portions you can cook in one go. A 2L basket suits one person; 4-5L handles two to three portions comfortably; 7.6L-9.5L dual-zone models can feed four to eight people. Cooking in batches wastes energy, so matching capacity to your household size matters more than buying the biggest model available. Dual-zone fryers with two drawers let you cook two different foods simultaneously at different temperatures, which is more energy-efficient than running two separate appliances or doing consecutive batches. For a typical UK kitchen with 600mm-deep worktop space, check the footprint before buying: a 9.5L dual-zone unit can be 35cm or wider, which may crowd a smaller galley kitchen.
03Price versus long-term value
Upfront price ranges from £25. 99 to £249.98 in this guide, but the cheapest unit is not always the most economical over time. A budget model that takes longer to cook, or that you replace after 18 months, costs more in the long run than a well-built mid-range fryer. Look at the 90-day price history: the Ninja AF300UK has dropped as low as £24.00 in the past 90 days, making it exceptional value if you catch a sale. The Tower T17100 has held close to its current £59.99 price, suggesting it is fairly stable. Checking the lowest 90-day price before you buy is the simplest way to avoid overpaying. Amazon UK and Argos both run frequent air fryer promotions, particularly around bank holidays.
04Hard-water areas and basket maintenance
If you live in a hard-water area (most of southern England and the Midlands), limescale can build up on heating elements over time, reducing efficiency and increasing energy draw. Dishwasher-safe baskets make regular cleaning far easier, and all eight models in this guide offer that feature. Non-stick coatings also reduce the need for oil, which is both healthier and cheaper. Check that the non-stick coating is PFOA-free, a detail now standard on reputable brands. For longevity, hand-washing with warm soapy water after each use is gentler than the dishwasher, even when the manufacturer says dishwasher-safe. A clean basket conducts heat more evenly, which shortens cook times and cuts energy use.
Our top picks
Best for solo cooks on a tight budgetChefman 2L Mini Air Fryer
At £25.99 (down from a 90-day high of £30.99), the Chefman 2L is the most affordable entry point in this guide. Its 2L basket is sized for one portion of chips or two chicken thighs, making it genuinely efficient for a single person rather than wasteful. The digital timer and shake reminder are practical touches at this price. Dishwasher-safe basket keeps maintenance simple.
Best dual-zone fryer for families of four to sixNinja Foodi Dual Zone Digital Air
The Ninja AF300UK's 7.6L dual-zone capacity lets you cook two different dishes simultaneously, cutting total cook time and energy use versus consecutive batches. Its 90-day low of £24.00 makes it one of the most dramatic price drops in this guide; at its current £179.00 it is still strong value, but worth setting a price alert. Rated 4.8 stars across over 18,000 reviews.
Best budget dual-basket fryer for larger householdsTower
The Tower T17100 offers a 9L dual-basket capacity with 10 one-touch presets for £59.99, a price that has barely moved from its 90-day low of £59.98. That stability suggests it is fairly priced rather than artificially inflated. Ten presets cover everything from chips to dehydrating, and the digital control panel is straightforward enough for everyday use without a steep learning curve.
Best mid-size fryer for two to three peopleRussell Hobbs Air Fryer
Russell Hobbs' 4.3L digital fryer draws just 1,300W, the lowest wattage in this guide, making it the most energy-efficient choice per session on UK 240V mains. Nine cooking functions include grill and keep-warm modes, and the temperature range of 40-200°C covers everything from gentle dehydrating to full-crisp air frying. Current price is £52.99, down from a 90-day high of £59.99.
Best large-capacity fryer for batch cookingNinja Foodi FlexDrawer Air Fryer
The Ninja AF500UK FlexDrawer's 10.4L removable-divider drawer is the largest single-drawer design in this guide, letting you cook one large joint or split the space for two dishes. At £243.99 (90-day low: £175.00), it is a significant investment, but the 7-in-1 functionality and non-stick dishwasher-safe parts justify the cost for households that batch-cook weekly to save on repeated oven use.
Best for versatile cooking across six to eight portionsTefal Easy Fry Dual Zone Digital
The Tefal Easy Fry EY901HG0 offers an 8.3L dual-zone capacity with eight cooking functions at £109.95, though its 90-day low of £67.98 suggests it is worth waiting for a sale. Coal Grey finish suits modern UK kitchens. Non-stick, dishwasher-safe baskets on both drawers make post-dinner cleanup quick, and the extra-crisp mode is well-suited to frozen foods common in UK meal prep.
Frequently asked
Are air fryers cheaper to run than a conventional oven in the UK?
Yes, in most cases. A typical UK electric oven draws 2,000W-2,500W and needs 10-15 minutes to preheat before cooking begins. An air fryer draws 1,300W-2,400W but reaches cooking temperature in under 3 minutes and cooks faster due to concentrated hot-air circulation. For everyday tasks such as chips, chicken pieces, or reheating leftovers, an air fryer will use noticeably less electricity. The saving is most pronounced for smaller portions where you would otherwise heat a large oven cavity.
What size air fryer do I need for a family of four in the UK?
A 7L-9.5L dual-zone model is the practical choice for four people in a UK household. That capacity lets you cook a main and a side dish simultaneously without batching. The Ninja AF300UK (7.6L) and Tower T17100 (9L) are both well-suited to this use case and priced under £180.00. If your worktop space is limited, measure the footprint before buying: dual-zone models are typically 35cm-40cm wide, which can be tight in a galley kitchen.
Is a dual-zone air fryer worth the extra cost?
For households cooking for two or more people, a dual-zone fryer is usually worth it. Running two drawers simultaneously at different temperatures means you finish a complete meal in one go rather than keeping one dish warm while the other cooks. That reduces total energy use and saves time. Budget dual-zone options such as the Tower T17100 at £59.99 make the format accessible without spending over £200.00.
How do I clean an air fryer basket properly?
All eight models in this guide have dishwasher-safe baskets, but hand-washing extends the life of the non-stick coating. After each use: 1. Let the basket cool for 5 minutes. 2. Soak in warm soapy water for 10 minutes if there is residue. 3. Wipe with a soft cloth or sponge. Avoid abrasive scourers, which scratch the non-stick surface. In hard-water areas such as London or the South East, dry the basket immediately after washing to prevent limescale spots on the heating element.
What is the best cheap air fryer in the UK right now?
The Chefman 2L at £25.99 is the lowest-priced model in this guide and suits one-person households well. For a slightly larger capacity on a budget, the Tower T17100 9L dual-basket fryer at £59.99 offers exceptional value: its 90-day low is £59.98, so the current price is essentially the floor. If you can wait for a sale, the Ninja AF300UK has dropped to £24.00 in the past 90 days, making it the best deal when it appears.
