Electricity-price sensitivity
| Electricity price | Energy saved/cycle | Annual saving | £250 premium payback | 5-year nominal net |
|---|---|---|---|---|
| 15p/kWh | 2.7 kWh/cycle | £147/yr | 1.7 yrs | £487 |
| 25p/kWh | 2.7 kWh/cycle | £246/yr | 1.0 yrs | £978 |
| 35p/kWh | 2.7 kWh/cycle | £344/yr | 0.7 yrs | £1,470 |
What can change the result?
Actual energy per cycle depends on load, programme, moisture level and appliance efficiency. Product price, capacity, drying time, maintenance and lifetime matter too.
The 4.5 kWh, 1.8 kWh and £250 premium figures are worked-example assumptions, not a claim about every dryer.
