Trinity Fire & Security Systems, part of Premier Technical Services Group Ltd (PTSG), is helping businesses nationwide adapt to sweeping changes introduced under the newly published BS 5839-1:2025 fire safety standard.
Released on 30 April 2025, the updated standard immediately renders the 2017 edition obsolete, introducing a raft of revised requirements that affect fire detection systems, maintenance schedules and compliance documentation across all commercial buildings.
Industry experts are calling it the most significant update in years, with Trinity’s technical team warning that failure to act could result in invalidated insurance policies, enforcement notices or financial penalties.
Among the key updates to the standard are:
- Mandatory detection at lift shaft tops for L4 systems
- Stricter guidance on ceiling obstructions and detector placement
- Flexible but consistent maintenance intervals (between 5–7 months, maintaining twice-yearly checks)
- Proof of ongoing CPD now required for engineers
- Updated certificate templates across all reporting and documentation
Trinity’s technical team commented: “This isn’t just about ticking boxes – it’s about maintaining operational resilience. By getting ahead of the changes, businesses can avoid unnecessary disruption while remaining fully compliant.”
With decades of experience delivering fire detection and life safety systems, Trinity has been closely tracking the development of BS 5839-1:2025 and has already implemented procedures to support its clients in adapting to the new requirements.
Importantly, the company’s approach remains focused on practical, cost-effective compliance – prioritising tailored advice and service over unnecessary system upgrades.
As organisations across the UK respond to the new regulatory landscape, PTSG – through Trinity Fire & Security Systems – is committed to delivering clarity, confidence and compliance in the face of complex change.
