The Regulatory Reform (Fire Safety) Order 2005 mandates that fire extinguishers should be regularly inspected and maintained by a competent person to ensure their operational readiness: "The responsible person must ensure that all premises, facilities, equipment, and devices covered by this Order or relevant enactments are properly maintained and in good working condition for the safety of relevant persons." (Pt. 2, Article 17). Supplementary to this, BS 5306 requires regular inspection of extinguishers.
