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 alarms for ease of use, value for money and alarm quality and sensitivity, in our exclusive survey.  

As ADT alarms are all monitored (that is, they connect to a call centre, rather than just making a noise) and come with a contract, we have also asked its customers to rate its monitoring service and response time after activation. 

In addition, we have asked how satisfied people were with ADT and whether they would recommend it to a friend, to give us an overall customer satisfaction score. The top monitored-alarm company gained a customer score of 78%, and lowest score was 66%.

ADT burglar alarms and prices

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.

All its alarms are wireless, where the different components connect via wi-fi, so there are no wires to hide. It also offers packages that include CCTV 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.

It also 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.

ADT products are only available from ADT and must be installed by ADT, so there are no DIY options. This includes the smart options, which often are possible to install yourself. 

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

Visit our burglar alarm buying page to find out more about the different options, including wired vs wireless, monitoring vs unmonitored, and smart alarms.
