Local aftercare backed by real customer feedback
“We had NOX Fire & Security install our commercial fire alarm system alongside an intruder alarm, and the whole experience was spot on from start to finish. Clean, professional installation, everything clearly explained, and the system is easy to manage through the app with instant alerts. The fire system is clear, reliable and easy for the team to manage without overcomplicating things. No pushy sales, no unnecessary contracts — just honest advice and proper workmanship. You can tell they care about doing things right. Highly recommend NOX for any business looking for fire or security systems in Chesterfield / Sheffield.”Rory StirlandCommercial Fire Alarm & Intruder Alarm
“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
“We recently had NOX install cameras, smoke screens, and alarms at our office and the whole experience has been spot on from start to finish. From the very first phone call with Isaac, everything felt straightforward and reassuring. He took the time to explain our options, answered all our questions, and helped design a system that made sense for our building and our budget. No pushy sales tactics at all, which was refreshing. The installation was smooth, the team were professional, and even after everything was fitted, Isaac has been on hand to help with any follow-up questions. A really great service and a company I'd happily recommend.”Nathan De La RosaCommercial CCTV, Alarms & Smoke Screens
