Air-fryers are the kitchen appliance that everyone's talking about. If you haven’t already bought one, you may be thinking about it or have caught wind of the buzz around them.


For those new to the trend, this clever gadget uses hot air rather than oil. It offers a healthier alternative to deep-fat frying while still giving snacks like chips a crisp, ‘fried’ finish.

Air-fryers have been gaining popularity for years. First launched in 2010, the appliance has evolved and some models now feature functions like baking, roasting, and grilling.

With UK energy bills set to rise again on 1 October, air-fryers are being touted as must-have cooking appliances that might help keep energy costs down – and sales are currently booming.

Traffic to our best air-fryers guide on surged 893% in the first two weeks of September.

Are air-fryers energy efficient?

As with all appliances, it's important to use them efficiently and air-fryers are particularly good for smaller portions or serving sizes.

“Large ovens may be able to cook bigger foods, cook more at once and be well-insulated,” but “their size may mean more energy is required to get them to temperature, and more energy could be lost if access to food is needed during cooking," according to air-fryer manufacturer Ninja.

“If you have a small air-fryer… there’s no need to heat up your whole oven to cook a single portion.”

So, by switching from an oven to an air-fryer for certain recipes, you could save on your energy bills depending on the appliances you’re using.

Archie Lasseter, sustainability lead from energy supplier Utilita, adds that because plug-in appliances like air-fryers heat up quickly, “typically heat is not lost into the surrounding space as in cookers, so [they] tend to be more energy efficient.”

That said, there’s no one-size-fits-all rule, and air-fryers can vary in energy efficiency. To calculate how much energy your air-fryer will use, multiply the appliance’s wattage by the number of hours it uses per day, then divide the total by 1000 to get the appliance’s daily kilowatt-hour (kWh).

The cost per kWh will vary depending on where you live and what your energy tariff is, but if you have a smart meter, you can see the cost per use as you’re cooking without having to calculate it.

Air-fryers vs ovens – which is cheaper?

Research by Utilita in August 2022 revealed that the annual savings of using an air-fryer could be up to £279.66 per year. Air-fryers on average were found to run at £55.91 per year, versus gas cookers at £121.06 per year and electric cookers at £335.57 per year.

Ninja also reports that you can cook 500g of frozen French fries in its Ninja Air-Fryer AF100UK model in 12 minutes for no more than 14p in electricity.

And the trend hasn’t stopped there – air-fryer recipes have been getting a lot of love on social media too, with fans taking to TikTok to film and share their favourites.

One TikTok influencer, @airfryerguy, who uploads lighthearted recipe videos using his air-fryer, has amassed 1.8 million followers since launching his channel in January 2020. Some of his most viral content has included air-fried poached paprika chicken and dessert nachos.

Air-fryers are certainly versatile. As well as being able to cook dishes like air-fryer sausages, buffalo cauliflower ‘wings’, and air-fryer chicken thighs using air crisp functions, several models also come with extra functions like baking, roasting, dehydrating, and grilling. This means you can experiment with other meals too, like puddings or roast dinners.


"Air-fryers are a game-changing bit of kit for making baked potatoes, with fluffy potatoes inside and a nicely cooked skin," adds Samuel Goldsmith, food copy editor for Good Food.

"I also love the fact I can cook ingredients I use often, like bacon and sausages, in an air-fryer. You get lovely, crispy bacon and well-browned sausages, and the air-fryer holds in the aroma much better."

"If I'm cooking something like air-fryer salmon or chicken breasts, I'll rub them with lots of spices or seasoning before popping them in."
