Looking for air fryer vs oven UK 2025 comparisons to find out which costs less to run. With UK electricity prices staying high, more households are switching from traditional ovens to air fryers to save money and cook faster. But is it really worth it — and how much can you save?
Let’s compare both for energy use, cooking time, and results using the latest 2025 models.
🔹 Why Compare Air Fryers and Ovens?
Air fryers have exploded in popularity because they use rapid hot air circulation to crisp food with minimal oil — often in half the time of a conventional oven.
Ovens, on the other hand, offer larger capacity and versatility for baking, roasting, and grilling — but they’re power-hungry.
💡 Quick fact:
- Typical air fryer = 1,500W, average use 20–30 mins
- Typical oven = 2,000–2,500W, average use 45–60 mins
👉 That’s a potential 50–70% energy saving per meal.
