  Great care

  I’ve had my alarm with DSI for over 10 years. From answering the call with Sue to having some one come out, it’s been friendly service, great customer care, would defiantly recommend them.

  Colin and Richard have given my home security a complete update - all v sophisticated and works a treat. And all done with existing wiring plus a few extra bits, so no mess.

  Technical issue with CCTV cameras

  Posted 03 February

  I was very impressed with the service from start to finish. The office receptionist was extremely polite and arranged the next available appointment for an engineer without any hassle. The engineer arrived promptly, was clearly very knowledgeable, and diagnosed and resolved the issue in under five minutes. Efficient, professional, and reliable and highly recommended.

  Alarm service

  Posted 10 January 2025

  I would highly recommend this company. We have been with them at least 15 years if not more and they have always been reliable and pleasant professional people. The office and engineers always keep in contact keeping you informed of appointments and arrival times so no waiting in all day. They are always helpful and easy to deal with, we once had an emergency with our battery overheating and they sent someone straight away. Also very good value compared to prices of other companies. As said at the beginning would highly recommend.
