An air fryer is a small, fast oven with a powerful fan. It cooks chips, chicken, vegetables and frozen food quickly and with little or no oil.

Where an air fryer winsWhere it doesn't
Quick small and medium mealsLarge roasts and big batches
Frozen food, chips, wings, vegetablesWet batters and very runny food
Heats up fast, so less waitingTakes worktop space
Generally uses less energy than a full oven for small portionsA small basket means cooking in batches

Running costs: an air fryer heats a small chamber, so for small and medium portions it generally uses less energy than heating a full-size oven. The saving depends on how you cook and what you pay per unit of electricity, so check the wattage on the product page.

The verdict: if you cook for one to four people and eat a lot of frozen or quick food, an air fryer is usually worth it. If you rarely cook, or mostly roast large joints, it is less useful.

Well-reviewed examples are below. We haven't tested them ourselves. This comparison is based on the Amazon listings and customer ratings, so check the latest price and details before you buy.

Short answer: For most households, yes. An air fryer heats a small space, so for small and medium portions it generally uses less energy than a full-size oven, and it cooks quickly. It is less useful if you cook large roasts or batch bake. Prices and ratings are from Amazon UK, checked when our catalogue was last updated. Prices change, so check the latest on Amazon.
