🔥 Raising the Bar: Why the Shift from BS 5839-1:2017 to BS 5839-1:2025 is Crucial

The safety of occupants in non-domestic premises hinges on the reliability of their fire alarm systems. As the built environment evolves and lessons are learned from critical incidents, so too must the standards that govern our industry. The transition from BS 5839-1:2017 to the new BS 5839-1:2025 is more than just an update—it's a fundamental elevation of professional expectations and a tightening of life safety measures across the UK.


Key Technical & Safety Upgrades You Can't Ignore

The 2025 revision introduces mandatory requirements where flexibility was once permitted, particularly for premises where the risk to life is highest. The days of using "variations" to cut corners are over.

🗺️ Zone Plans: From Optional Extra to Mandatory Must-Have

One of the most significant changes is the new, non-negotiable requirement for Fire Alarm Zone Plans.

     No Variation Allowed: The absence of a clear, accurate zone plan is no longer permitted as a variation for any system with more than one zone.

     Sleeping Tenants are the Priority: This is especially critical for premises with sleeping tenants (such as hotels, care homes, and student accommodation), where the ability for responders (including the Fire and Rescue Service) to quickly identify the precise location of a fire is a matter of life and death. A zone plan translates a panel's zone indicator into an immediate, actionable location.

⚡️ Earthing: A New Colour Standard for Safety

To ensure clarity and alignment with modern electrical standards (specifically BS 7671), the colour coding for specific system wiring has changed:

     Functional Earth Sleeving: All functional earth conductors (FE) used in fire alarm installation wiring systems must now be identified with pink sleeving rather than the traditional green and yellow. This streamlines the identification of fire system wiring and reduces the risk of incorrect termination.


The New Gold Standard for Professional Competency

Perhaps the most impactful shift in BS 5839-1:2025 is the formalisation of what it means to be a "Competent Person" and the emphasis on ongoing learning.

🎓 Competence is Now Explicitly Defined

The new standard defines a competent person as someone who is "suitably trained and qualified by knowledge and practical experience." This seemingly simple clarification carries enormous weight:

     No Excuse for Outdated Knowledge: This definition directly addresses the reliance on older qualifications. Holding a certificate for BS 5839-1:2017 is no excuse for not understanding the current 2025 recommendations. Complacency is no longer an option in a life-safety critical field.

     Beyond a Single Course: The standard makes it clear that maintaining this competency cannot be reliably achieved by relying on a single training course taken years ago.

🔄 The Mandate for CPD Records

The path to staying competent is now formally linked to Continuing Professional Development (CPD):

     Maintain CPD Records: All individuals involved in the fire industry, from designers and installers to maintenance engineers, must maintain accurate CPD records. This makes training an essential and auditable part of the fire professional's career. It creates a verifiable link between professional practice and up-to-date knowledge.
