How we worked out the cost
We use a typical figure of 0.5 kWh per day for a typical fridge freezer running all day, every day. At 26.32p per kWh, that is 0.5 × 26.32p = £0.13. Over a week of 7 days it is £0.92, and over a year £47.90.
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
- Keep it away from the cooker, do not leave the door open and keep the seals clean.
- 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.
