ADT UK&I Reviews 

I ordered a system and paid a £250 deposit, the system wasn't right for us so we cancelled on the 19th june and told it will take 10 working days for a credit, this never happened so I phoned again and was told it has been cancelled and will receive my refund. Another wk later I phoned again and was told its definitely been cancelled on the 6th July and ill get a refund in 10 working days, im now on day 12 and still no refund I think I need to contact the ombudsman this is just a shocking service I have to give at least one star on here or it would have been a zero

Lovely polite quick engineer he was a great guy provided a great service

The two engineers were extremely professional, informative, helpful and polite

Engineer did a fabulous job.
I would definitely recommend him.
Alarm is working fine is a big upgrade on my previous one.

Hastin Harris was very professional and polite.

Member of staff on time.
Very efficient, helpful and very pleasant. Completed the entire job in a good time.

I cannot over emphasise the care and attention to the installation of my updated ADT alarm system today. The engineer was patient despite some issues and explained exactly what the delay was caused by. He ensured that I was happy with the new system and confident to use it. Thank you!

Matthew Woodall did his best as usual. Very efficient.

Glen Clarke from ADT Alarms was fantastic from start to finish. He was polite, professional, and genuinely friendly throughout the whole visit. He took the time to explain everything in detail, walking us through how the system worked and answering all our questions patiently. His knowledge and clear communication gave us real confidence in the installation, and made us feel great about choosing ADT as our intruder alarm provider. Highly recommend Glen and the team — couldn't have asked for a better experience.

Fabulous service from everyone I dealt with - in particular, Chesney, the installation engineer, couldn't have been more helpful or efficient. Highly recommended!

Matthew Woodall was very professional, friendly and extremely helping during my annual check, he replaced all the batteries and added the emergency options to the panel. Thanks Matthew

Matthew Woodall was on time. He was polite and explained what to do . Thank you

Honestly, I haven’t had a bad experience like this in a while. I requested a refund from this company on the 25th of June 2026 and to this date I still haven’t received it. I requested a refund as reading the small prints in the terms and conditions, you never own this equipment and will be surcharge to the monthly fee and when the contract ends they will bind you into another contract for another ‘upgraded camera / alarm service’ to ensure you cannot get out of it. It’s really wrong. Also if for instance someone comes out to your house (the person to check if the alarm has been triggered and you are not there) you are subject to pay the hourly rate for the person and this isn’t covered in the contract. I would advise everyone to read the terms and conditions carefully.
The customer service just to get my refund back has been really appalling i’ve been really patient but after 26 days this is just beyond a joke. I’ve had to request a chargeback through my bank as I have had no joy.

He was ok doing the job said he could not service one part of the censore in the front room with a new battery because it had paint on it but the room was painted before the alarm was put in his name was Mathew

Great service for the installation of the new digital upgrade and then later for the remote reset… though I was disappointed that the reset procedure took a while to organise- a call to general support and then a wait for a call back from whoever deals with remote resetting.

Excellent quality product and excellent service, very happy with the system,

Engineer was called Glen he was lovely start to finish on time made me feel at ease showed me what security system I got asked me where to install also showed me how to download the ADT app no faults at all. Glen showed me how to use the app with seeing recordings and going live etc he was brilliant. I would recommend ADT to anyone the service was fantastic the payment plan and package suited us for what we needed.

Excellent service from ADT. Brooklyn Railton, was professional, knowledgeable, and very helpful. He installed the system efficiently, explained everything clearly, and made sure I was confident using it before he left. A great experience from start to finish—highly recommended

Very well explained every step of the process. Very helpful

The engineer came on time, did the job of installing the alarm system efficiently, set up the ADT App for us on my mobile because I am not IT conversant. He added our camera and door bell details on one ADT App. He was very understanding polite and compassionate about old people like us and changed the Wi-Fi details on all the cameras and the door bell which had not been functioning since we had changed WiFi hub.
