The Code for Sustainable Homes was introduced in 2007 and Part G of the Building Regulations now includes water efficiency for the first time. In addition, improved water efficiency in new developments will be backed-up through the planning system, as the Government allows the planning system to mandate water efficiency targets in excess of the Building Regulations where there is demonstrable local need.

If you are building a new home, you must ensure that it will have a predicted water consumption of less than 125 litres per person per day.
