The TL;DR
A 1,500W air fryer running for 20 minutes costs about 13p at the current price cap. A 2,500W oven for 35 minutes, including preheat, costs about 38p.
The detail
- Four meals a week, that’s a difference of about £52 a year.
- These are maximums — thermostats switch on and off, so real use is lower.
- For big batches the gap narrows, because you might need several air fryer rounds.
