Non Domestic Fire Detection & Fire Alarm Systems BS 5839-1:2025 Updated

The new BS 5839-1:2025 standard is now live, offering critical updates to the design, installation, commissioning, and maintenance of fire detection and fire alarm systems in non-domestic premises. This latest edition replaces BS 5839-1:2017 and reflects evolving industry best practices, regulatory expectations, and technological advancements.

Why Staying Current Matters
Keeping up with the latest fire safety standards is essential. Working to BS 5839-1:2025 ensures systems are compliant, reliable, and aligned with modern risk management strategies. Outdated practices can compromise occupant safety, increase legal and financial risk, and damage professional reputation.

This updated Code of Practice supports fire safety professionals, facilities managers, designers, and contractors in delivering legally sound, high-performance systems that protect lives and property.

What’s New in BS 5839-1:2025?
Effective from 30 April 2025, this revision introduces substantial changes aimed at:

  • Improving system effectiveness and fault monitoring
  • Enhancing fire detection in specific areas like lift shafts and lobbies
  • Clarifying requirements for manual call point locations and mounting
  • Addressing false alarms and emergency service integration
  • Standardising maintenance procedures and record-keeping

These changes provide clearer guidance, promote consistency across installations, and reinforce the importance of competent design and ongoing maintenance.

Who Needs to Know?
Whether you’re a business owner, fire risk assessor, installer, or building manager, understanding and applying BS 5839-1:2025 is essential for ensuring safety and compliance in non-domestic buildings. The new standard strengthens the UK’s fire safety framework and underlines a shared responsibility: to build and maintain environments that are safe for all occupants. The best way to tackle all fire safety related elements is to consider a professional fire risk assessment.
