Trinity Fire & Security Systems (a constituent company of Premier Technical Services Group Ltd) is helping businesses navigate the most significant fire safety update in years.
BS 5839-1:2025 arrived on April 30th, instantly making the 2017 edition obsolete.
This isn’t a minor update – it’s a fundamental shift affecting detection requirements, maintenance protocols and documentation standards across all commercial properties.
Key changes include:
· L4 systems now require detection at lift shaft tops
· Enhanced guidelines for ceiling obstructions
· Maintenance intervals can flex within 5-7 months (while staying twice yearly)
· Engineers must have proof of ongoing CPD

- All certificate templates need updating
“This isn’t just about ticking regulatory boxes – it’s about avoiding disruption to your business,” explains Trinity’s technical team.
Non-compliance could invalidate insurance policies, lead to prohibition notices, or result in hefty fines.
As specialists in fire detection and life safety systems, Trinity’s nationwide team has been preparing for these changes since they were first proposed.
Their approach isn’t about selling unnecessary upgrades – it’s about practical, cost-effective compliance.
