Martin Lewis has warned people that it is not always cheaper using a microwave or air fryer instead of an oven.
In the current cost of living crisis, many households in the UK have invested in air fryers from the likes of Ninja and Tower, with the belief that they are more economical than using an oven.
People have switched from using their ovens but Mr Lewis said people need to think carefully before they do this as they may actually end up paying more in some circumstances.
