In Northern Ireland and Scotland, under The Water Supply (Water Fittings) Regulations (Northern Ireland) 2009,  and The Water Supply(Water Fittings) (Scotland ) Byelaws 2014, it is a requirement to notify the water supplier of the intention to install water systems for fire fighting, including domestic fire sprinkler systems.

In England and Wales there is no such requirement under The Water Supply (Water Fittings) Regulations 1999 however, consultation between householder and water supplier is strongly recommended as the flow rate of water required by a sprinkler system may exceed that available from the water main.
