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

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