Electricity-price sensitivity
| Electricity price | Energy/use day | Annual energy | Annual cost |
|---|---|---|---|
| 15p/kWh | 1.00 kWh/day when used | 260 kWh/year | £39/yr |
| 25p/kWh | 1.00 kWh/day when used | 260 kWh/year | £65/yr |
| 35p/kWh | 1.00 kWh/day when used | 260 kWh/year | £91/yr |
Important assumption
Dishwashers heat water intermittently rather than drawing rated power continuously. A measured kWh-per-cycle figure is preferable.
This is a worked planning estimate, not a measurement of your appliance. A smart plug, energy monitor or manufacturer annual-kWh figure usually gives a better real-world input for cycling appliances.
