The Building Regulations Approved Document G: ‘Sanitation, hot water safety and water efficiency’ came into force in April 2010. Together with the Code for Sustainable Homes, it ensures a reduction in water use, sets standards for water quality and promotes the safety of hot water systems.

The Water Calculator provides evidence that water has been used less profligately.

Presented by Julia Trew, the main author of the Approved Document, and by other leading experts in the field, this programme examines the key issues and explains the various methods of compliance.
