What Trinity Fire & Security Systems does

Trinity Fire & Security Systems Ltd is a UK-based turnkey provider of fire detection, life safety, fire suppression and integrated security systems, headquartered in Exeter and operating through nine regional offices across England, Scotland and Wales. Founded in 1997 and acquired by PTSG (Premier Technical Services Group) in January 2019, the company employs 500+ qualified engineers delivering design, installation, commissioning and 24/7 maintenance services to commercial, healthcare, education, aviation, industrial, public sector, defence, heritage, hospitality and residential clients. The portfolio spans fire alarm systems, kitchen fire suppression, portable extinguishers (including the award-winning MPF Multi-Purpose Fluid extinguisher developed with LifeSafe Technologies), emergency voice communication, public address and voice alarm, S-Quad self-test detection, and electronic security/access control, supported by third-party certifications including LPS1014, LPS1204, NSI NACOSS Gold, ISO 9001, NICEIC and BAFE.

Revenue is generated through two complementary mechanisms: project-based professional services for design, installation and commissioning of new systems, and recurring managed-service maintenance contracts sold in three SLA tiers (Premium, Premium Plus, Premium Enhanced) on annual billing cycles. Go-to-market is enterprise field sales, with named clients including Heathrow Airport Terminal 3, University Hospitals Bristol NHS Trust, Aneurin Bevan University Health Board, Balfour Beatty, Entrust Property Services and ABM Technical Solutions, complemented by CPD training partnerships with Gent/Honeywell, Notifier and Hochiki. Disclosed turnover is £70 million per the company careers site, with stated revenue exceeding £60 million on the corporate website.

The proprietary MPF extinguisher, certified to BSI and NTA 8133 standards, positions Trinity at the intersection of regulatory tailwinds (PFAS/PFOA foam phase-outs) and the rising commercial demand for lithium-ion battery fire suppression, supported by a three-time Tomorrow's FM Award record and a £4,000 engineer sign-on incentive reflecting demand-driven scaling of the field service workforce.
