Fire sprinkler systems in the UK must comply with British Standards that define how systems are designed, installed, tested and maintained. These standards ensure reliability, performance and long-term safety. At GFS, all systems are installed to the correct BS standard based on building type and risk level.
BS 9251 covers fire sprinkler systems installed in homes, apartments, HMOs, care homes and residential buildings. It sets requirements for:
System design categories based on building height and occupancy
Water supply methods, pump options and stored water volumes
Pipework materials and installation standards
Coverage requirements for rooms and escape routes
Testing, commissioning and ongoing maintenance schedules
This standard is used for most domestic and residential installations in the UK.
BS EN 12845 applies to commercial, industrial and higher-risk properties. It includes more detailed technical requirements such as:
Hazard classifications (LH, OH, HHP, HHS)
Pump and tank configurations
Hydraulic calculations for higher-risk environments
Protection levels for storage and industrial settings
System monitoring and fault alarms
Systems designed to BS EN 12845 provide increased resilience and are typically required for commercial developments, plant rooms, warehouses and manufacturing facilities.
Following the correct BS standard ensures:
Full compliance with UK fire regulations
Acceptance by building control and insurers
Reliable performance in a real fire situation
Long-term system safety and easier maintenance
Accurate design based on building use and risk category
GFS ensures every fire sprinkler system is designed, installed and maintained to the correct British Standard so clients benefit from a fully compliant and quality-assured installation.
