• Key points
– Benefits of personalised in-home advice to enable the greatest water and energy
savings; utilising ‘moments of change’ to introduce or reinforce water efficient
behaviours
– Need to carefully apply any high level messaging on water efficiency
– Understanding water use practices rather than attitudes, behaviours or simply
volume used

Developing the evidence base

• Defra report includes a forward look
• My thoughts
– PR14 and the challenge of delivering large scale water efficiency programmes
– Continuing the collaborative water efficiency fund – strategic research
– Review and update evidence base – needs to be functional to support Water
Companies and policy making
– Water Resources Management Plans 2019 and integrating a new range of policies
– Answering some of the remaining questions from Walker Review – who is
responsible for water efficiency?
– Transitioning to Water Sensitive Cities and learning from
international experience
What next for Water Efficiency?
