Executive summary
We missioned environmental and engineering consultancy Entec to assess the
viability of different options for retrofitting water efficiency into existing homes in the South East.
Entec was missioned by the Environment Agency to undertake a more in-depth
exploration of effective ways of increasing water efficiency in existing homes, building on the
findings of the earlier study.
The objectives of the study were:
• to review the range of water efficiency measures identified in the previous study, ‘Water
Efficiency Analysis of South East England Rollout Options (Entec, September 2005)’;
• to review any other similar studies and assess whether to consider other measures;
• using the best options and the most up to date information, to assess the scope for reducing

• using up to date information, to fully assess the costs and benefits and identify the pros and
cons of these approaches.
