Looking for the best air fryers for low energy cooking UK 2025 to save money while still enjoying crispy meals? Air fryers use rapid hot air circulation to cook food up to 60 % faster than ovens, making them one of the smartest appliances for energy-conscious kitchens.
🔹 Why Air Fryers Are Energy-Efficient
Conventional ovens can draw 2–3 kWh for a 45-minute bake, costing around 70 p at today’s rates. A mid-sized air fryer uses roughly 0.5 kWh for the same meal — about 12 p. Multiply that by daily use, and you could save £150–£200 per year depending on your cooking habits.
They also heat instantly (no preheating needed) and maintain steady temperatures, meaning less wasted electricity overall.
