🍽️ Best Value Dishwash
20:55
ECO wins by 3p over SPEED, the next cheapest: its electricity costs 1p more, but it saves 4p of water. Every setting at its own cheapest window, under the prices still to come:
The cheapest window for ECO starts Mon 02:00 and runs 6 half hours, where the Agile price averages 30.4p a kWh.
Half hour by half hour: Octopus's price, the power assumed in each five minutes, spread evenly until a run of ECO is logged, and what each half hour costs:
| drawn | a kWh | costs | |
| 2:00 | 518 Wh | × 31.66p | 16.41p |
| 2:30 | 518 Wh | × 30.82p | 15.98p |
| 3:00 | 518 Wh | × 30.75p | 15.94p |
| 3:30 | 518 Wh | × 29.80p | 15.45p |
| 4:00 | 518 Wh | × 29.03p | 15.05p |
| 4:30 | 518 Wh | × 30.16p | 15.63p |
| electricity | 3110 Wh | 30.4p | 94.45p |
| electricity | 3.11 kWh × 30.4p a kWh | 94p |
|---|---|---|
| water | 28 litres × 0.42p a litre | 12p |
| total | shown as £1.06 | £1.06 |
On Flexible Octopus, at 26.60p a kWh, the same wash costs 94p, so on Agile it costs 12p more.
The kWh and litres are the manual's, or scaled from them, for a full load; it does not give them for each drying level; water is £4.2067 a cubic metre with sewerage.
