About Us

Our Roots

Diamond was founded in 1987 by Tom Snoddon, a Belfast born and bred entrepreneur who saw a niche in the market for a local company with the capabilities to deliver complex fire and security projects, to a highly professional standard. The company’s original maxim was “Large enough to cope, small enough to care”. This personal level of service has been ever present throughout over 30 years in business, and our customers feel supported and protected. Diamond is a leading provider of high quality commercial security and life safety systems, including Fire Detection and Alarm Systems, CCTV, and Intruder Alarm Systems.

Our Growth

Sheer grit and determination saw Diamond survive not one, but two recessions. Huge changes in technology during our growth demanded a constant focus on innovation, research, and development. The ability to remain agile enabled us to respond to our customer’s ever-changing requirements with future-proof solutions. Early adoption of third-party approval with the leading industry body, and trading partnerships with innovative global equipment manufacturers, enabled our Belfast business to deliver world-class security and life safety projects. Today we are a second-generation family business with a reputation for excellence and innovation, always with the customers’ needs at the forefront of all our solutions.
