This report developed by Waterwise assembles information about water efficiency educational programmes and measures used to evaluate their impact. A literature review was undertaken and information was requested directly from water companies and other organisations. The study reveals that many different educational programmes are taking place in the UK while their effectiveness remains under-investigated. Knowledge gaps exist regarding what educational activities are most effective, whether behaviour change is long-term, as well what type of evidence is collected or incentives offered. It is recommended to evaluate more educational programmes with consistent approaches and facilitated by professional guidance to produce more reliable knowledge.
