How Often Do Domestic Fire Sprinklers Need Servicing?

Domestic fire sprinkler systems in the UK need a full inspection and service by a competent person at least once every 12 months, as required by the British Standard BS 9251:2021. This annual servicing ensures all components are in good working order, checks for leaks or corrosion, verifies water supply functions, and confirms that nothing obstructs the heads. 

What an Annual Service Involves

A professional service includes:

• System Integrity Checks: Inspecting for any signs of leaks or corrosion on the pipework. 

• Component Examination: Ensuring all sprinkler heads and cover plates are clear of obstructions and decorative materials. 

• Water Supply Testing: Verifying that the water supply functions as designed and that the system has the correct pressures and flows. 

• Alarm System Connection: Checking that the system is correctly linked to an alarm system that activates during a flow test. 

• Coverage Confirmation: Confirming that the building layout changes haven't affected the coverage of the sprinkler heads. 

• Securing the System: Making sure the system is secured and clearly labelled. 

Why Servicing Is Crucial

• Legal Requirement:It is a legal requirement to service fire sprinkler systems annually to ensure compliance. 

• Reliability:Regular maintenance ensures the system will operate correctly and reliably when needed in the event of a fire. 

• Preventing Failures:Annual checks help to identify and address issues like corrosion or blockages before they can lead to component failure or system malfunction. 

• Safety:Maintaining life safety equipment is vital for protecting occupants and property from fire.
