Great Service

The advisor was really trying to give me as much help as possible to tackle my problem and even went the extra mile to say he will call me back in hour and a half to see if the camera doorbell is working as it should be.

Good work by the ADT engineers

Good work by the maintenance engineer. Came on time and did the work with a minimum of fuss.
More recently my system was upgraded. Again, good quality of service, which included a relocation of a sensor following a useful discussion.

Excellent Service So Far.

The initial application and the following installation were done with considerable ease.
Requirements were given via a telephone appointment and the salesman assisted with advice re areas that may or may not have needed coverage.

After the initial appointment was made, i had a couple of calls from customer services offering earlier visits by the engineer. Sadly we couldn’t accept either but this was a welcomed service.

On the day, we were advised of the arrival time of our engineer, Gavin, with plenty of notice. He was very smart and polite and, during the course of the installation, it was quite clear that he knew the system inside out. He also arranged for a refund for a monitor that was not required as coverage for that area of the house was already covered.

The response of ADT to an activation not disarmed by us was fully explained, followed by a comprehensive guide to how the system worked and how to set up the ADT app on our devices.

Installation time was roughly 3 hours. This included the removal of our old system plus Gavin clearing up any dust and debris.

I have had to call customer services just once as the ‘My ADT’ app (separate to the alarm app) would not allow me to register.

This was sorted within 24 hours.

All in all, an excellent service so far.

My new alarm system was installed…

My new alarm system was installed yesterday by Jack who was excellent. He communicated in advance about his arrival, explained everything and undertook all the work with minimal disruption and great care to my surfaces. He was very personable and explained everything about how the system works.
My annual service undertaken by Dwain is also excellent - he is clear, efficient, he explains everything and makes good recommendations about the system.
My ADT alarm itself meets all my security needs and gives me great assurance. Now i control it with the Ap its even better. I would highly recommend ADT’s services and staff.

ADT Fault Visit

Anthony Pinnock visited us to replace a faulty battery in a panic alarm. He was very professional and knowledgeable throughout his visit and we feel he is a credit to ADT.
