The new 2009 version of Approved Document G (sanitation, hot water safety and water efficiency) published in October 2009.

The revised Part G will feature enhanced hot water safety and efficiency measures for all new homes, with inbuilt protection from hot water scalding in baths using protective devices to limit hot water temperature, and the introduction of a new minimum standard of 125 litres of water per person per day.

The main amendments to the Building Regulations are:

* The requirement that baths in new homes are fitted with protective measures, such as a thermostatic mixing valve, to limit the temperature of the hot water
* A water efficiency standard of 125 litres per person per day for new homes
* Extending existing safety measures to all types of hot water systems (not just vented systems)
* Setting out where greywater and harvested rainwater can be safely used
