What Triangle Fire Systems does
Triangle Fire Systems, founded in April 2002 and headquartered in Hastings, East Sussex, is a UK fire protection services contractor delivering design, supply, installation, and maintenance of life-safety systems for built assets. Its service portfolio covers residential and commercial sprinkler systems, dry and wet risers, passive fire protection (compartmentation, fire doors, fire stopping), service and maintenance, and in-house electrical services. The company operates a full lifecycle model spanning new-build installation, retrofit programmes for legacy buildings, and ongoing inspection and maintenance contracts.
The business serves enterprise B2B customers across four core segments: housing associations, local councils, national construction firms, and property developers. The named customer base includes major contractors such as Wates Property Services, Kier, ENGIE, Tide Construction, and Countryside, alongside national housebuilders including Berkeley Group, Bellway, and Redrow, and a long roster of social-housing landlords and local authorities including Peabody, L&Q, Clarion, Hyde, Birmingham City Council, and Wandsworth Council. The company's flagship engagement is a 4,000+ retrospective sprinkler installation programme across 80 high-rise residential blocks delivered for Birmingham City Council via Wates Property Services, positioning Triangle Fire Systems as a major UK retrofit contractor in the post-Grenfell remediation cycle.
Revenue is generated through project-based installation contracts, framework agreements (notably the CHIC Framework and KCS Procurement), and recurring service and maintenance work. The business holds IFC and FIRAS third-party certifications, is a signatory of the Building a Safer Future Charter, and was named to the Sunday Times Growth 500 in 2025. A £9 million growth capital investment from BGF in April 2022 has funded platform expansion, followed by the November 2024 acquisition of Intrinsic Fire Protection and a 2025 CEO transition to Marcus Wallis, consistent with a scaling-phase UK fire-safety contractor.
