Research Survey - Water retrofitting policies review: The household perspective - WT0913

This project would develop work undertaken in two previous studies (undertaken by WRc and Waterwise) to confirm the range of water consumption in new homes and identify the main drivers for different water use. Preliminary analysis conducted by waterwise, based on three company data sets shows that on average homes built since 2002 use more water than homes built between 1991 and 2001. The data is remarkably consistent bearing in mind that the three regions represented by these companies differ in their demographics, per capita consumption, climate, geography, etc. This evidence is based on consumption data for all new homes (over 360,000 in total) in each company’s area since metering of new homes became normal practice.
Defra are now interested in exploring the factors that could explain this apparent difference between consumption in these two groups of properties. WRc have considered possible explanatory factors, and methods by which it would be possible to test their influence on the consumption. Possible explanatory factors could be Occupancy, Metering performance, Plumbing practices, Boiler type, Appliances in the home, Socio-economic classification.
Evidence base on water consumption within new homes is required to inform policy making. This project would establish the water consumption from all new homes in a number of water companies’ area to provide robust data on the level and range of consumption. The project would also investigate any differences from average micro-component use within overall household use.
