Staying Ahead in Fire Safety Compliance
At SecuriGroup Systems, we are committed to keeping our clients informed and protected.
The release of BS 5839-1:2025 marks the first major update to the UK’s fire detection and alarm system standard since 2017. Here’s what you need to know and how we can help you stay compliant and safe.
What is BS 5839-1?
BS 5839-1 is the British Standard that sets out recommendations for the design, installation, commissioning, and maintenance of fire detection and fire alarm systems in non-domestic premises. It is the benchmark for professionals responsible for ensuring fire safety in buildings and is widely recognised as best practice across the industry.
Why Does BS 5839-1 Matter?
This standard is essential for compliance with building regulations and is referenced by regulatory authorities, insurers, and enforcing bodies. It is shaped by lessons learned from real-life incidents and evolving technology, ensuring that systems are designed to protect both life and property.
What’s Changed in 2025 and Why?
British Standards are reviewed every five years to ensure they remain fit for purpose. Each update reflects advances in technology, new risks, and insights from serious incidents.
The 2025 revision responds to a changing risk environment and the need for stronger, more integrated safety measures. It also aligns with updates to related standards, such as BS 7671 for electrical installations. The new code of practice ensures that fire detection systems keep pace with industry best practice and regulatory requirements.

What Does This Mean for You?
From April 2025, all fire safety work must comply with the new standard. BS 5839-1:2025 places greater emphasis on continuous professional development for technicians and requires Alarm Receiving Centres to maintain a higher level of site knowledge. Compliance is a shared responsibility, covering service providers, property managers, landlords, tenants, and keyholders.
At SecuriGroup Systems, our expert fire professionals are fully up to date with the latest standards. We are here to guide you through the changes and ensure your systems remain compliant, effective, and robust.
