The best advice I can give you, is AVIOD. Find a good local company who will be far cheaper in the long run and offer a greatly level of service. Having been a customer for 8 years for both CCTV and an Alarm, I have found that if you happily pay for the service each month (which does come at a premium cost) and do not need their service/support, then great! however - as soon as you have any problems with your alarm of CCTV, that is where ADT's service falls down drastically. When you call to get an engineer visit, they book one in, however the engineer will not turn up. When you chase that visit you simply get "sorry", we will book another.. and it goes on and on. Having ha 7 appointments now re-arrange, I have received another "sorry" we will book for next Friday... When you pay for a service such as an alarm or cctv, you appreciate that your monthly ££'s sometimes isnt value for money, however with some comfort that when you need to call upon that service then you can call upon it. Sadly - When ADT are called upon, they go missing - 7 times and counting missing. My best advice - there are many local alarm companies who can offer the same level of product, such as a police response alarm... support a local company, not this multi national company who sadly have lost all customer value and service.
