Based on a 2 person household having 2 showers each day, lasting 5 minutes each, and using 6 litres a minute a minute to get soap and suds away, your electric shower will typically cost £230.00 a year.

When its time to replace your electric shower, switching to a Shower Power Booster can pay for itself in the first year. Buying an £80 electric shower does not stop there as you will need an electrician to fit it and once installed it will eat up electricity (and you should budget to replace it every 3 years).

COST OF SHOWERS USING ELECTRICITY – £229.34
Water used for a 6 litre a minute shower for 5 minutes = 30 litres.
Cost of water is 30 litres at 0.1p a litre = 3p.
4 person household at 1 shower a day 365 days a year = 4x365x3p = £43.80.
For each shower:- Cost of electricity 12.2p per KW/HR so 12.5KW x 12.2p x (5/60) = 12.7p
4 person household at 1 shower a day 360 days a year = 4x360x12.7p = £185.54
TOTAL £229.34
