Draft of Building Regulations Approved Document G now available
The amended version of Approved Document G Sanitation, hot water safety and water efficiency was laid before Parliament on 13 May 2009, and is now available to download.
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.
Housing Minister Iain Wright said, "Hot water scalding in baths is a real risk particularly for groups like children and the elderly and the Government has been committed to finding a way of doing more to protect people from these injuries".
He added, "Homes account for a quarter of the country's carbon emissions so it's essential we tackle this as part of our efforts on climate change. Water plays an important role in making homes more sustainable, and the measures we announced today will help make new homes even greener as part of our commitment to zero carbon homes from 2016".
Please note: Approved Document G is now due to come into force in April 2010.
