We cannot recommend National Security Systems highly enough. From start to finish, their service has been nothing short of exceptional. As a small charity supporting D/deaf and disabled residents across Islington, it’s crucial that all our sites are safe, secure, and accessible. National Security Systems delivered on every front. Their customer service is outstanding – responsive, respectful, and always willing to go the extra mile to understand our specific needs. Their team treated our staff, volunteers, and service users with professionalism and care throughout the installation process.

We've used NSS for many years and cannot fault them. At short notice, they were able to scope, quote and install a new wireless alarm system for us in a week's turnaround. Incredibly pleased with the new solution and the work carried out.

The admin from NSS contacted me to confirm booking the day before my appointment with rough ETA for the engineers. The installation team arrived on time, did a quick survey and made some recommendations on placement of cameras and recorders. They quickly and professionally completed the installation, help me set up the app on my devices to be able to view the CCTV live and recorded footage remotely and helped clarify some of my questions. Very friendly and knowledgeable. Highly recommend this company. It's the 2nd job they've done for me. Fantastic yet again! Phone support brilliant too!

My install engineer was Jay who was on time as scheduled. He fully explained what was going to be installed and exact locations. Once complete, I was given a full walk through on the system and how it’s used. 5* service.

Very Professional

I purchased a new property last year with an NSS alarm system already installed. I made contact with the company to come round and set it up for me and do a maintenance check. It was a pleasure meeting Randeep, the engineer who came round, set things up and was patient and personable. I decided to upgrade the system so alarms go to a call centre. Randeep arrived on time and carried out the work professionally and quickly. Not forgetting Geeta and Rohit in the office, who have such a kind manner. NSS are a great company and a pleasure to do business with.
