Fire Sprinkler Systems – domestic or residential classification?

There were 2 types of non-commercial fire sprinkler systems prior to the update of BS9251  in 2015  Domestic and Residential. These two terms were misleading because in the UK,  architects and homeowners use the same two words ‘Domestic’ and ‘Residential’ to describe properties which are neither business or commercial property. However there are clearly defined differences between the two terms in North America. Domestic impling a dwelling for one family irrespective of size of property and residential classification which is used for a larger properties like Care Homes, Hostels and high rise blocks of flats which would require a more robust system.

Domestic and Residential Classification


The most significant difference between the 2 classifications within the original version of BS 9251 concerned the run time of the two fire sprinkler systems  and the quantity of sprinkler heads (and consequently the quantity of water) required and allowed for in the system design.

The head spacing and areas of coverage (all rooms, excluding bathrooms below 5m2) will remain the same in either case. This means that for a given floor plan, the pipe run may well be the same in the 2 systems although the pipe sizes may differ in places in order to accommodate higher flow rates.

As somebody who feels that it should be a necessity for all properties to have fire sprinkler systems, I am a big fan of this company. I have used them numerous times to service my home system and they are very knowledgeable. I would highly recommend their service.
