Despite overwhelming evidence of their effectiveness, sprinkler systems remain optional in most English residential buildings. We present the financial and safety case for installation.. The Evidence Is Overwhelming Buildings with sprinklers see: 80% reduction in fire deaths 70% reduction in property damage 60% reduction in injuries 99% of fires controlled or suppressed by sprinklers The Cost Reality For a typical new build residential block, BS 9251 sprinkler installation costs: £1,500–£3,500 per dwelling 1 2% of total construction cost Offset by reduced insurance premiums, reduced fire rating requirements, and potential design flexibility Wales Shows the Way Since 2016, all new residential buildings in Wales must have sprinklers. The result: zero fire deaths in sprinklered Welsh dwellings since the mandate. Why England Lags Behind The cost benefit analysis used by MHCLG to justify the 30m threshold has been widely criticised. The APPG on Fire Safety has called for sprinklers in all buildings over 11m. Design Benefits Sprinklers can enable: Longer travel distances Larger compartments Reduced fire rating requirements in some elements More flexible architectural design We design cost effective sprinkler strategies.
