CSS Connelly Security Systems Ltd

CSS Connelly Security Systems Ltd is a family business established in 1986 by three brothers: Jim, Pat and Paul Connelly. The company opened for business in the summer of 1986 from a small office in Bishopbriggs, Glasgow. CSS was the first security systems company in Scotland to be awarded the quality standard BS5750. It also achieved 'Investors in People', a Scottish first for a security systems company. CSS owns and operates an alarm receiving centre.

The average length of service among staff is 14 years, and many staff have been with the company for over 25 years. CSS has grown through acquisitions of other companies. It provides commercial security solutions including intruder alarms, CCTV, fire alarms and life safety, access control, servicing and maintenance, house builder packages, Intruder DisMist System, retail security tagging systems, and electrical services for businesses.

Edinburgh-based CSS Connelly Security Systems Ltd draws on a customer base that stretches back many years, with users describing a relationship lasting well over a decade and service that has remained consistent throughout. Interlinking of smoke, heat and carbon monoxide detection is a task that recurs in feedback, and reviewers highlight how swiftly and cleanly engineers carried it out, often finishing sooner than anticipated.

Response times feature prominently, including a sensor issue resolved quickly and a late-afternoon call to arrange fitting of a replacement battery so that a client was not left waiting until the start of the following week. Engineers are frequently commended for their courteous manner and depth of knowledge, fielding questions about possible future problems. Reception and call centre personnel are likewise singled out as helpful. The firm supplies and maintains burglar and fire alarm equipment, and its electrical installation work is reflected in the range of services listed.

Not every account is favourable. Some reviewers describe difficulties reaching the service department, promised return calls that failed to materialise, and waits of several weeks before learning that works would not go ahead. Others refer to charges taken after cancellation, trouble securing a refund, and maintenance enquiries that turned into attempts to sell extra products, a contrast with the positive experiences of long-term clients.
