Information-based interventions for household water efficiency in England and Wales: evidence, barriers and learning opportunities

Following the call of the UK’s Department for Environment, Food and Rural Affairs in its recent Water Efficiency and Behaviour Change Rapid Evidence Assessment 2018, this article seeks to understand the key barriers to effective information-based interventions to encourage household water efficiency in England and Wales and their implications. We review the evidence on information provision to conserve water in England and Wales. We then set out the current key barriers, highlight what might have contributed to the barriers and, based on learnings from the literature, clarify some underlying confusion and suggest ways to improve.
