CSL has invested extensively in building the largest customer-facing team in the security industry

Bowmark Capital, the mid-market private equity firm, has backed the £32 million management buyout of CSL DualCom (CSL), the UK’s largest provider of dual signalling products and services for intruder alarms. CSL pioneered dual signalling in 1996, offering the first credible alternative to existing alarm signalling whilst setting the current standard for professional dual-path security monitoring.

Since the 2006 MBO, CSL have propelled the DualCom product to become the UK’s best selling dual signalling system and the preferred choice for over 120,000 professional security installations in commercial, retail and residential premises and the favourite for over 2000 alarm installers.

The company has grown rapidly over the past five years led by managing director, Phil Hollett and Simon Banks, co-founder and commercial director. CSL has invested extensively in building a strong management structure and have the largest customer-facing team in the industry sector providing unrivalled support, innovation and a track record of fifteen year’s experience in the security industry.

Bowmark are very pleased for the opportunity to invest alongside the senior management team and are looking forward to a long-term association within the security market.

CSL’s long-standing relationship with business partner Vodafone has supported CSL in the design of Gemini; the most resilient and reliable managed network in the industry. Gemini is wholly owned and operated by CSL. The deployment of geographically diverse servers combined with the unique DualCom WorldSIM technology has reduced line fault false alarms to less than one in every three years. The DualCom Gemini managed network is the engine that powers DualCom’s signalling integrity and grants all DualCom products with exemplary reliability in the delivery of alarm signals into all of the UK’s Alarm Receiving Centres. The company’s premium Grade 4 product monitors the integrity of the signalling path every minute 365 days a year.
