Calculate your water and energy use
Making simple changes in your household can help reduce your water and energy bills.

We’ve teamed up with the Energy Saving Trust to help you calculate the cost of water and energy use in your home.
The water energy calculator allows you to input your water use at home and in the garden.
It then generates customised results based on your household’s water consumption with associated energy use, carbon emissions and a total cost per year. It also provides water saving tips which could cut your household bills.
Variables such as water and energy tariffs are kept up to date by the Energy Saving Trust. You will need Adobe Flash Player to use the calculator.
