Got stuck tonight with an annoying alarm. Called the out of hours service. Fault sorted 10 mins. Used this company for years and will do for more. Good old fashioned customer service. Thanks from C.A.R.S. Ltd.

I can not recommend GCS highly enough. Their service has been fantastic from phone conversations right through to quote and installation. We already had an intruder alarm system with ADT but were not happy with their service at all. After a particularly bad run of customer service we decided to get a new system installed. From the start Paul went out of his way to help. So happy to have switched to such a great company
