Oliver Heald: To ask the Secretary of State for Communities and Local Government if he will take steps to promote water efficiency in the building of new homes; and if he will make a statement.
Andrew Stunell: Part G of the Building Regulations already sets water efficiency standards for new homes which require that, on average, their water consumption is no more than 125 litres per person per day (average national use is approximately 150 litres per person per day). The voluntary Code for Sustainable Homes promotes higher water efficiency standards. Homes funded by the Homes and Communities Agency are required to reach level three of the code which includes a water efficiency requirement of 105 litres per person per day.
