The automatic Fire sprinkler system is the most widely used Fire protection system today. Sprinklers have been used to protect property and life since 1872 and modern innovations have made Fire sprinklers even more effective at combating Fire. These systems are designed to protect property or life as specified by the various automatic Fire sprinkler standards. Within commercial properties, the British standard BS EN 12845:2015 would be used. In special circumstances, some of our systems are designed and installed to NFPA 13 and FM Global standards. Over 40 million sprinkler heads are fitted worldwide every year.

Sprinkler systems are simple in design. However, to comply with building regulations, the insurer or fire officer, they must adhere to the standards to achieve compliance.

The most common conventional installation used in most applications. Pipework is permanently charged with water, ready to be discharged in the event of a fire.


Used in areas where the temperature is sub-zero and prone to freezing. The pipework is pressurised with air; once the air pressure is reduced due to a head activation, the control valve will release water into the pipework.


Used generally to protect high hazard industrial areas and fuel/gas tanks as once activated, all heads are operated to completely envelope the fire in water.


Systems that change between being wet and dry, depending on the time of year, are generally not installed any longer due to the high maintenance costs and internal rust issues. We can service and maintain these systems.


Used in high hazard areas normally around fuel such as in aircraft hangars, the water within the system is mixed with a low or high expansion foam solution to create an effective means to cover the fire and extinguish it.


Pre-action systems are best used in areas where sprinklers would need to be activated in extreme fire situations for example server rooms. Generally single knock or double knock are used, Single knock requires both the sprinkler and an electrical alarm such as heat/smoke detector to be activated for water to be discharged. Double knock is where the sprinkler and two electrical alarms have to be activated for water to be discharged.

 The typical sprinkler installation, comprises of CPVC Pipework located above the ceiling, with concealed sprinkler heads positioned flush to the ceiling, which is supplied either from the water mains or from a storage tank via a pump. When a sprinkler operates, the flow of water in the pipework operates a flow switch which in turn operates an alarm system. The flow of water is small, usually less than 1/100th of the water used by the Fire and Rescue Service.
