Great service from ADT
We phoned ADT and they treated our concerns seriously. They sent an engineer the same day as we needed a repair to our smoke alarm detector. We needed a new detector and panel and these were ordered and fitted the next working day. The engineer, Jake Basheer, was excellent from start to finish. He fitted the new items quickly and afterwards, showed us clearly how to use the new panel and asked us if we had any questions for him. He said that we could get in touch with him if we ever need any extra help. We were very happy with his expertise and warmth. Thank you.

After break-ins in our area we decided to get an alarm system, ADT was not the cheapest or costliest, after agreeing terms and making deposit they were down within a week, arrived on time, took four hours to install cameras, flood lights and indoor sensors etc, showed me how the system worked from the main console and then helped me down load app to phones and computer and make sure all was working, have had no issues so far, the system and staff seemed very professional all through process.

Waste of time
So having the cameras fitted in wales with bad wind a rain I want one to the front and one to side of property, the fitter didn’t want to fit them around the side as it was easier for him to put both out the front, they didn’t work properly for months on end, I rung up to ask could my one camera be moved to the side of my property, was told no, then my partner asked because our contract was up in April this yr could we lower payments was told no!
So we cancelled then, it’s been a total waste of time and money but since we cancelled, our cameras are picking up as they should be now we are having alerts as we should of had from the last 18 months, not happy at all. the fella who answered our call was ok and he did ask to decrease

My husband dealt with you and reports that when he called to request a remote reset there was apparently no gatekeeping security - no questions asked just a straightforward what’s the issue and then dealing with it. The person on the end of the line was polite, efficient but we were definitely spooked by the apparent lack of security to check my husband was who he said he was and not say a burglar?

Great Engineer!!
Brooklyn Railton installed my alarm system. Brooklyn came out twice as I wanted my alarm system fitting as soon as possible, but I did not have Wi-Fi so I was able to have the house alarmed without the camera for a couple of weeks. Brooklyn then came out to me again to fit the camera.He was great, he took his time to explain the app and the full system. He discussed other upgrades and was overall such a lovely engineer. The sales and installation set up team were not so good - very unorganised, no communication within the team.
