23 Use an air fryer
An air fryer is one of the cheapest ways to cook. Typically, 10 minutes of cooking in an air fryer costs about 5p, while electric ovens cost almost double that. You could cook two chicken breasts in an air fryer in as little as 15 minutes (under 10p), but electric ovens need about 30 minutes (20p). See our air fryer reviews on page 117.
24 Swap oven and hob for microwave
According to Energy supplier Utilits, a microwave costs just 8p a day to run, while an electric cooker costs 87p, based on the average amount of time they're used for. If you prefer cooking on the hob, however, you could swap to an energy-efficient induction hob over a ceramic one to save cash.
25 Use a slow cooker
It will take longer but using a slow cooker will save money over an electric or gas oven. Energy supplier Utilita saysJust boil the water you need for a cuppa, rather than filling the kettle. To boil a cup of water costs around 1.28p while a full kettle costs 6.8p. To put this into perspective, two cups a day only boiling what's needed would cost £9.34 per year, but if you boiled a full kettle each time, it's £49.64!
