Review by Bracken

"Wanted a new alarm fitted so I can operate from my phone. Contacted several companies for a quote but Defence Security provided a great value option compared to others who were several hundred pounds dearer and provided less. I had 7 sensors fitted, a key pad door sensor all for £740. My monthly subscription is £19.99 for monitoring by Defence Security, the mobile app and includes servicing fees. Pete and Lee who fitted alarm arrived on time, were very pleasant and personable. They got on with the job and cleared up the small amount of mess made from drilling etc. I loaded the app and Lee took time to explain the simple features. My friend referred Defence to me and she received £100 for the referral which she kindly split with me so my overall cost was reduced by £50. Happy days! Would highly recommend."
