An electric shower heats water on the spot with a powerful element, so it is one of the priciest things to run by the minute. Enter its power, how long you shower and how many showers a week to see the cost.
Electric showers are typically 7.5kW to 10.5kW, far more than most appliances, which is why even a short shower adds up across a household. The two levers are time and the number of showers; the power rating is fixed. For a full breakdown see electric shower cost and hot water savings.
Common questions
How much does an electric shower cost per use?
A 9.5kW shower for 8 minutes uses about 1.27 kWh, which at 26.11p costs roughly 33p a shower. Across a family that is a few hundred pounds a year.
Is an electric shower cheaper than a bath?
Often, because it uses less hot water, but a long power shower can cost more than a bath. The deciding factor is minutes under the water, not the label on the unit.
