If you're considering investing in an ADT burglar alarm, read on to find out how its customers rate it, based on our exclusive survey. 

See how ADT alarm owners rated its monitored alarm systems for ease of use and value for money, as well as overall customer satisfaction.

ADT alarms are all monitored (that is, they connect to a call centre, rather than just making a noise) and come with a contract.

In addition, we have asked how satisfied people were with ADT and whether they would recommend the brand to a friend, to give us an overall customer score. The top monitored alarm company gained a customer score of 73%, and lowest score was 59%.

ADT home security

ADT products are only available from ADT and must be installed by ADT (including its smart options – see below); there are no DIY options. 

ADT monitored alarm systems

ADT offers two levels of service: keyholder response (whereby ADT calls you or nominated friends/family if the alarm is triggered) or police response, in which case it will also alert the police. Both services mean paying a monthly fee.

  • The cost of a keyholder-response alarm system starts from 89p a day, which would mean paying £325 a year. This is just for the monitoring contract - you would need to buy the alarm itself, too (see below).
  • The cost of a police-response alarm starts from 99p a day, which would mean paying £361 a year. Again, this is just for the police response contract, not the alarm itself.

Wireless alarm systems

All ADT alarm systems are wireless, where the different components connect via wi-fi, so there are no wires to hide. 

It also offers keyfobs/tags (pictured below), which allow you to set and deactivate your alarm using a key, rather than a number.

Smart home security

ADT offers smart alarms, which you can control and monitor from your mobile phone or tablet. These also come with a monitoring contract, costing from £361 a year or around £398 if you want police response. 

You can buy smart alarms from other companies that don't have monitoring contracts. This means you can still monitor the alarm yourself, without the added fee, although you may need to pay for data storage. Find out more in our guide to smart security systems.

Smoke alarms and home security cameras

ADT also offers packages that include CCTV home security and smoke alarm monitoring. 

With the ADT smoke alarm monitoring, it will alert the keyholders and the fire brigade if the alarm goes off. This service starts at 7p a day, so £26 a year.
