Great install from Brooklyn

Had Brooklyn Railton install my new system yesterday. He was very thorough, polite and friendly. Before he started any works, he walked through my home and made sure he knew everything I wanted doing. Unfortunately, through no fault of his own, he couldn’t do everything I had originally planned for. But he did try his best and explained everything in detail as to why it was best not to go ahead with it. Including making sure I wasn’t paying for the things he couldn’t do.
He removed my old system with as little destruction as possible (old system) and installed the new system with as little disruption as possible.
Once everything was set up he went through all the functions I needed to know and made sure I was confident with everything before he left.
He’s a testament to your team, keep hold of him! You can tell he has pride in his work.

ADT alarm system reinstalled

I was very impressed with ADT from the very first contact through to the reinstallation of my alarm system (which had been left by the previous owner of the house). They guided me through the entire process step by step, making everything straightforward and stress-free.
A special mention to Olly, the engineer who carried out the (re)installation. He was polite, professional, and incredibly helpful throughout. I couldn't have asked for better service. Super recommended!

Rubbish new alarm systems (stay away)

I had a ADT Alarm system installed many years ago (hardwired) was a great system, did the job perfect, very loud very loud and had a CO2 system as part of the deal. That alarm system recently developed a fault and I stupidly instead of getting repaired maybe chose a new ADT system these new WIFI enabled systems WHAT A LOAD OF RUBBISH, please keep away maybe perfect for business premises but not the home. The system is not loud at all there is no chance a intruder would be deterred by the sound of this alarm system, I know ADT will reply and state they are a monitoring alarm service company but what will that do for me if my alarm system goes off at night while me and my family sleep how will we prepare ourselves in that event as we would not hear the alarm go off and I may not hear phone notiications.

Very poor alarm system please look for alternatives Verisure being one who offered me a internal siren as part of the package and ADT wanting to charge me over £250 for a internal siren, even though being a customer for over 26 years!!!!

Now ADT will not allow me to cancel my contact even though its been around 6 days since I had the alarm installed but complained on the day of the installation, very rude, arrogant customer services and complaints team..

Shop around guys ADT is not always the best !!!!

ADT Failure to have technical support from 7pm to 7am for residential alarm systems…

Failure to have technical support for domestic customers from 7pm -7am has been the company position currently and for at least most of this year . Having been a customer for more than 14 years , i have seen unacceptable changes in standards of service since mergers with other companies over the years. Including over many months no technical qualified support in the evenings. Sadly i had to monitor my own system, when alarm went off in the early hours and calling to find out why I and key holders had not been called. To learn the system had not been receiving appropriate signals ( due to engineer visits) to upgrade system and alleged failed to reset and set up correctly after upgrade. This was to say a very worrying experience and to have to do the investigations ADT should be doing. The customer should not be monitoring and being expected to scrutinise standards that fall below what the customer is paying for in their contract, is unsafe and unacceptable.
I would urge other customers to seek their records from ADT of signals and system setting. Insurers in the event of an incident will no doubt be checking your policy and declarations and system record of alarms to central station. I have had to raise an issue with NSI due to lack of adequate responses from ADT. Engineers are always pleasant when they attend but where the failure truly arise and the cause and clarity are factually severely lacking.
