An interactive online tool to help customers save money has been launched by Thames Water.
The free water calculator makes predictions based on responses to questions about how much water people use in the home and garden.
The answers then help to calculate energy use, from heating up water for things like showers and baths, and show how simple changes can lead to money off both bills.
Thames Water says it is the first calculator of its kind.
