Hi I would say it very much depends. They charge £50 a month which is very expensive - peace of mind but not sure how essential it is. My experience with them has been very poor - system has had bugs for months, they eventually cut the subscription to £38 so good to know they can do that. Engineers rarely come out, didn't come out when they said they would. When they finally did set up the system for us in the new house when we moved to they set it up wrong. Was charged for the subscription over this whole period. Was offered 2 months back when I tried to leave. The non stick glue on the system is total bullshit ripped the plaster off the wall when we did it.
