| Energy used per year | 946 kWh |
How we worked out the cost
We use a typical figure of 1.3 kWh per 8-minute shower for a typical 9.5 kW electric shower for 8 minutes. At 26.32p per kWh, that is 1.3 × 26.32p = £0.34. Over a week of 14 showers it is £4.79, and over a year £249.09.
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
- Shortening a shower by two minutes saves around a quarter of its cost.
- Heating is the biggest use of energy in most homes, so draught-proofing and insulation save more than any appliance.
- Heat only the room you are using and use a timer or thermostat.
- Keep hot water tank temperature at about 60°C and use a timer for an immersion heater.
