Customer reviews
Feedback about local servicing and support
“Seamless journey from start to finish! I filled in the simple form and was soon contacted by the team. They were very knowledgeable, professional and really listened to my needs. I have since had a system installed. The price was much less than I had expected and so far the aftercare has been great. I can't recommend them enough!”Jeremy BuntingSecurity System Installation
“Brilliant service from NOX. Super professional, knowledgeable, and they went out of their way to be helpful. Everything was explained clearly and in detail. The install was tidy, and the whole process was smooth from start to finish. We were thinking about getting a security system for a while and now we're so glad we went with NOX. Would 100% recommend to anyone.”Ryan HargreavesAjax Alarm System
“Really impressed with NOX Fire & Security. Isaac, Joe and James made everything super easy from start to finish — no pressure, just honest advice and a system tailored exactly to what I needed. Love how personalised it is, and being able to control my heating, washing machine and lights all from the same security app is a game changer. The lads were friendly, tidy, and took the time to show me how everything worked before they left. Feels good knowing it's all been done properly. Would definitely recommend.”Sasha BrailsfordAjax Smart Security & Automation
