Automatic water mist systems for domestic and residential premises: Welsh Government guidance

Automatic fire suppression and Building Regulations in Wales

In April 2011, The Domestic Fire Safety (Wales) Measure brought in the mandatory requirement to provide automatic fire suppression in new residential premises in Wales.

Purpose of guidance

This guidance on automatic water mist systems is primarily intended for use by Building Control Bodies to assist them in assessing water mist systems for new and converted domestic and residential buildings in Wales, i.e. water mist systems for:

 new buildings

 conversions for existing buildings (change of use)

 extensions of an existing building already having a water mist system.
