How we worked out the cost
We use a typical figure of 1.5 kWh per hour of cooking for a typical fan oven at 180°C, including the thermostat cycling on and off. At 26.32p per kWh, that is 1.5 × 26.32p = £0.39. Over a week of 7 hours it is £2.76, and over a year £143.71.
These are typical estimates rather than lab measurements. Your appliance may use more or less, so adjust the kWh in the calculator for your own.

How to reduce the cost
- Cook several things at once and avoid preheating for longer than you need.
- Use a microwave or air fryer for small meals instead of the full-size oven.
- Put lids on pans and match the pan size to the ring.
- Batch cook and reheat, and defrost food in the fridge instead of in the oven.
