Learn more about Triangle Fire Group.

Triangle Fire Group was established in 2021 to allow for further acquisitions as part of our growth strategy. Triangle Fire Group started as Triangle Fire Systems in 2006, established by three brothers and run as a family business.

Triangle Fire Systems continue today, specialising in residential and domestic fire sprinkler systems, commercial fire sprinklers, wet and dry riser mains and passive fire protection. We also have an in-house electrical team and servicing department for an all-encompassing service. Since 2006 Triangle Fire Systems has experienced growth and success, quickly increasing our workforce, service offerings and business acquisitions.

In April 2022 Triangle Fire Group secured a £9m investment from BGF, the UK and Ireland’s most active growth capital investor.

This investment has given Triangle the capital and support needed to expand the company and indeed to resource our commitment to offering the best customer service whilst expanding.

We ensure our clients are kept safe from non-compliance, ensuring the highest safety standards are met with exemplary consistency. We are proud to be FIRAS certified, proving our high standards and dedication to delivering value to our customers all around the UK. We are the comprehensive solution to fire safety.

Customer Feedback

What our customers are
saying about us.

Triangle continue to be professional, proactive and innovative in their approach to retro fit sprinkler systems. They always put the customer first and will always find a way to complete the project with minimal disruption to our residents

Steve Key MIFireE, Fire Risk Technical Lead, Midland Heart

Triangle have been working with Wates Property Services and SES to deliver circa 4,000 retrospective sprinkler installations across 80 high rise blocks in Birmingham for Birmingham City Council.

We have enjoyed a truly collaborative relationship with Triangle, who worked as part of a dedicated supply chain delivering up to 6 blocks in unison, ensuring we met the promise to Birmingham of delivering the works by March 31st 2021.

I have recommended Triangle to other parts of Wates who are looking at sprinkler programmes with respective clients, and would use the services of triangle on future programmes.

Daniel Camp, Operations Manager, Wates Property Services

We have worked with Triangle on a number of projects and found that on each occasion they have provided a design solution bringing both efficiencies and financial savings, they have negotiated with statutory authorities to ensure compliance and at all times maintained the design and installation programme. Both Commercial and Residential elements have been a joy to work with Triangle to achieve a complete package

Associate Technical Director, Countryside Properties

I awarded Triangle Fire Safety Systems full contracts for all Wet Riser, Dry Riser and Sprinkler design and Installation  on all the above projects.

For me their expertise in this field has been of paramount importance in the successful construction and delivery of the above projects and as important the ongoing operation  of these for our valued clients 

The Triangle team as a whole and notably Warren Root and Steve Chantler have always performed professionally and to a high standard with regard to Design, Safe Installation , Installation Quality, Programme and Budget Requirements
