The calculator will estimate the cost per year for your water use, which also includes your sewerage costs — please remember you are charged for sewerage costs separately by either Southern Water or Thames Water, depending on where you live. The calculator uses industry averages when working out energy cost and the calculation is based solely on the energy associated with the hot water usage stated in the calculator.
