How much does a fridge freezer cost to run?
This worked example uses 50 W, 24 hours on each use day and 365 use days per year. Change any of these inputs in the calculator.
438 kWh/year · 1.20 kWh per use day
Electricity-price sensitivity
| Electricity price | Energy/use day | Annual energy | Annual cost |
|---|---|---|---|
| 15p/kWh | 1.20 kWh/day when used | 438 kWh/year | £66/yr |
| 25p/kWh | 1.20 kWh/day when used | 438 kWh/year | £110/yr |
| 35p/kWh | 1.20 kWh/day when used | 438 kWh/year | £153/yr |
Important assumption
The example uses 50 W as a 24-hour average draw, not compressor nameplate power. Annual manufacturer kWh data is better.
What changes fridge freezer electricity use?
Fridge-freezers cycle their compressor and defrost systems, so nameplate power is not representative of continuous use. Room temperature, appliance age, door opening, thermostat setting and ventilation around the condenser can all change annual electricity consumption.
Make this estimate more realistic
The energy label or manufacturer annual-kWh figure is usually the best starting point. For an older appliance, a multi-day energy measurement can be more informative. Compare annual kWh between old and replacement models, then value the difference at your own unit rate.
Electricity prices change, so the 15p, 25p and 35p/kWh rows are sensitivity examples rather than a current-tariff claim. Use the linked calculator with the unit rate shown on your own bill before relying on the annual cost.
