This report seeks to demonstrate the link between water and energy to consumers and promote the benefits of adopting water and energy efficient behaviour. Three communication and marketing approaches were tested for their effectiveness. The three-year project was conducted in London, Edinburgh and Cardiff, where over 25,000 people received advice on water efficiency. A survey of people receiving the advice was used to evaluate the impact of the message and method of delivery. It showed that awareness about the fact that saving water saves energy increased from an average of 8% before to 16% by the end of the project. Recognition about the importance of saving water grew from 78 % to 93% over the course to the project.
