Installer was great
Installer was great. Quoter was good too, although at times unnecessarily lengthy explanations became confusing, but that came from a genuine desire to make sure everything was clear

Alarm Service and Maintenance
Had my alarm serviced today by Matthew Woodall, he was very polite and professional. He phoned to let me know when coming, arrived on time and was very respectful of the property. After he'd checked everything was working well, he even told me about extra features on the system I didn't know about.
Great service, I wouldn't hesitate to recommend to anyone.

Peace of mind
Adrian Cook, the engineer arrived on time. He was friendly and assured me that he would explain everything to me, as the system I'd had at my previous property was an older type and this one was through WiFi. He was very patient and made sure I was confident with the system before he left. Definitely 5*

Generally a good installation… however
Generally a good and speedy installation, however installer had left his ladders at a previous job and despite me providing my own steps for him he decided to stand directly on the edge of my cream coloured sofa to e install a replacement sensor and then left brick dust on the top of the sofa and on the carpet behind - also made no attempt to clear brick dust from carpet on the landing.

Long contracts reduce flexibility
ADT’s professional monitoring may suit customers who want a managed security system, but published residential terms can include a 36-month agreement. Early termination may cost 75% of the remaining monthly service charges, so the long commitment deserves close attention before installation.
