National Security Systems Group

NSS really are the very best company we have ever come across for residential security systems. They are extremely accessible and responsive when we have any issues or questions. We had our original security system installed in 2006 - 17 years ago and they have serviced it ever since with prompt efficiency. Whenever minor faults have developed, they are very responsive at all hours and can access the system remotely to address or isolate any faults and arrange a date if an engineer needs to attend. We have dealt with Ash, Jay has visited many times, Randeep, Harry and Vin (who now deals with Corporate security) and also Gita in the NSS Admin office. This week, Jay and Harry came to completely upgrade our security and fire alarm system (also changing it from Analogue to WiFi for emergency connection alerts to Southern Monitoring) and check every single aspect of the installations around the house. As ever, they were prompt, efficient and as unobtrusive as their multiple tools allowed. They completed the job within their estimated time and took us through the changes to our entry/exit panel and explained everything very clearly. We cannot recommend this company highly enough. In 17 years with them, we are not aware of any staff changes; any time we have had to call out an engineer or have an annual service, we can be certain that it will be somebody familiar to both us and with the layout of our home. We trust them implicitly.

I have been using NSSG for my home alarms for over 15 years now and on this occasion they upgraded my entire alarm and CCTV system. The service we received from the engineer (Jay) this week was beyond fantastic, on being faced with a problematic fixed wall panel in the kitchen which required a CCTV screen to be fitted to it. Jay managed to gain access to an area behind the panel which seemed impossible to reach and with no damage or signs of entry in order to connect the screen. Another great example of thinking out of the box which is very much the NSSG hallmark. Over a period of two days Jay completed a full alarm & CCTV upgrade, adding various sender units behind wall-mounted TV's, extra CCTV cameras, door shocks and contacts including a roof beam and the list goes on. On viewing the finished work, it is like everything was always present - their work is always neat, clean and very tidy. From a technical point of view, I have never found anyone better when it comes to complete security installs (alarms / CCTV) and they can even design a system tailored to your specific needs. Their engineers are always polite, professional and nothing is too much trouble for them. In regards to aftercare, the customer service team, the technical help desk team are truly some of the nicest most helpful genuine people you will ever encounter. I would highly recommend Vince and his team and from my experience of using them, there is simply no one better than NSSG!.

Engineer turned up on time. Polite, clean and tidy. Explained what he was going to do and checked in with me throughout. Cleaned up after himself as well and was quick and efficient. Will definitely use them again.

Extremely pleased with a very professional and efficient service carried out with pleasant manner. A very professional service.

We have just moved to a new house and inherited the existing alarm system which was supplied by NSS some years ago. Having transferred the maintenance arrangements we have now upgraded the system to a modern control unit and alarm panels. The price quoted was very reasonable and the work done over three sessions by a great team who communicated well and explained what would be dealt with on a subsequent visit. The upgraded system is now fully up and running and we are very happy with the work done.

Finefair have been using NSS for our head office and residential properties over the last 6/7 years. NSS are our go-to company for any CCTV and alarm jobs. All of our jobs no matter how big or small are all dealt with efficiently and professionally. Thank you to team at the offices, who are extremely helpful and courteous when booking in appointments, services, and monitoring visits. I would also like to take this opportunity to thank Dee, Hitesh and Rohit for there attention to detail and professionalism.

My old alarm system was becoming problematic. NSSG provided competitive quotes for the various options. During the installation (which was professional and fast) I changed my mind about the number of sensors I required and they managed to include it in the installation at a very reasonable price

If you're looking for prompt, professional and reliable service, look no further! Had my security system replaced by NSS today. Not only did NSS call to offer a cancellation, J arrived on time, explained the steps and completed the work in an organised manner. Was impressed with J's conduct and patience. NSS followed up the same day to ensure satisfaction. I don't expect any problems but know where to go should I need help. Used NSS before and they always deliver.

Dave and his team have continued to provide excellent CCTV services for our school since taking over from a very poor company a couple of years ago. Our intruder alarm provider has also declined in service provision in the last few years so we asked NSSG to upgrade and take over our intruder alarm services. They have recently done this and were quick, efficient and provided very good advice as always. As a school we work very hard to find good service providers to work with and I have no hesitation in recommending them.

Excellent service. Every thing was done extremely professionally. Every one is so helpful and do their best to please Customers like us. I would recommend them to anyone any time. Ashok Sharma

Before selecting NSS for my burglar alarm, I did a lot of research and got quotes from 6 other companies too. I found the NSS quote competitive. All the companies I got quotes from installed Pyronix branded burglar alarm systems, and the equipment was more or less similar. But it was the customer service that set NSS apart. The main reason I selected NSS was because of the service and knowledge provided by the surveyor, Ash, who came to visit me and subsequently who I dealt with afterwards until installation. I'm very detailed and I have bombarded Ash with so many questions, via email, Whatsapp and calls, and he always gets back to me straight away, he is very helpful, knows his stuff technically and generally a nice guy. Ash is a real asset to the business and I would definitely recommend NSS. If you are able to request which surveyor you deal with, would recommend asking for him.

NSS have now carried out a number of installations for our company. They have bent over backwards to accommodate our needs and are constantly there to guide, help out and advise. I wouldn’t use any other security company going forward as they cannot be more helpful and professional...brilliant company and wonderful people and they are hugely competitive...I cannot recommend them strongly enough.

Vin & Co from NSS were instructed to fit CCTV and a security alarm system at my newly purchased home prior to me moving in. Honestly, best decision I had ever made. They set up all the cables whilst the house was being gutted and did a fantastic job from start to finish. Not only polite but highly professional and honest. Completely transparent and always there to help 24 hours if something goes wrong. This is the peace of mind I needed. The icing to the cake is that they are all just so friendly. I would highly recommend them, their service for installation through to aftercare is second to none. Tech guys are amazing! Thank you for making me feel safe and working with me since mid last year! Ps. Also apologies if I gave you a headache during this process with my demands! Highly appreciated :)

A professional company with excellent communication skills from initial sales enquiry through to completion of work. All staff were diligent and informative at all times. We were treated like individuals and our needs were listened to at all times. Engineers were tidy, knowledgeable and a real pleasure to have in our property. The aftercare service has been impeccable too. Price and customer service are a great match! We would definitely trust and recommend NSSG team!

We have used NSS on a few CCTV and alarm jobs. they always go the extra mile. Very knowledgeable. Highly recommend.

NSS have done an great job with our CCTV and Alarm System. Their staff are very helpful and happy to go the extra mile. I would highly recommend them. We feel safe and secure with their systems in place.

I have been with this company for a few years. I know that I will definitely change alarm companies next year. This company started out as great value for money however I had a problem last year where they failed to detect that my alarm was not working correctly for 6 weeks which would have been a breach of my home insurance policy. To resolve this, I had to pay for an upgrade to the system to avoid the fault reoccurring - therefore the solution cost was passed on to the customer. You are only allowed one free maintenance visit a year after which you would have to pay for a call out. This is different to other companies I have been with who did not charge for more than one call out. Also this company tried to charge an extra 2.5% for payment via credit card today. When the January 2018 law change was pointed out, they suddenly no longer accepted credit card payments. I need to have trust in the company who provide security to my home and this has now been eroded.

Really pleased with the work carried out. The guys were really professional but still personable. Everything was left neat and tidy and explained to me really well before they left. I wouldn’t hesitate to recommend the company to anyone.

A great company with helpful staff and a pleasure to deal with. NSS provided my wife and I with great service and were very professional throughout the process. Nice and tidy installation by an experienced fitter and very prompt with their timings. I would definitely recommend them to family and friends in the future.

I would like to thank Ash and all at NSS for doing an excellent job. From my initial call to NSS Ash was very helpful and professional. NSS were able to install my alarm within 2 days of my initial enquiry a week before Christmas. That was very impressive. I would highly recommend NSS to anyone who is thinking of installing a high quality alarm system . Thank you NSS. Hardeep .

Really cannot praise they guys enough they went above and beyond on the job to exceed my needs and expectations. Workmanship is top quality and equipment is fantastic quality. Thanks guys

Fitted a new alarm system in our new office block Great professional job highly recommended - all well installed and explained

NSS did a great job for us. They went through all the details and listened to everything we wanted. Both the workman were polite and worked with care and precision. The cables and cameras are all so well fitted that you cannot even see the cables. They provided a training session and helped with the setting up of the apps on our phones. A really truly outstanding service. Nothing was too much trouble from the start to the end and the entire team are very professional. I would have no hesitation in recommending NSS.

Used NSS recently for some works. Everything from initial visit, estimate, execution and after-sales was excellent.

All members of the team I met with were efficient, professional and courteous for alarm fitting. They were all knowledgeable and open to any trouble-shooting questions. Evidently with their own support team behind the scenes, it was good to know all queries covered. Good turnaround. Above all - Good teamwork from start to finish. All in all a good job, very well done.

Thoroughly impressed with the work carried out by technicians Jay & Mayan. Both chaps were professional, informative and courteous whilst carrying out work at our property. I have absolutely no hesitation in recommending NSS (namely the world-class customer service provided by Jay & Mayan) to my friends, family and clients. Thank you once again.

The company provided an excellent quick service with exactly what we needed. Work was completed efficiently and training provided was clear. Thanks very much

Without any hesitation I would recommend this firm, I would add that I can be quite a difficult customer and changing my mind several times before the installation (and even during) but nothing was too much trouble. The work was carried out professionally. We were kept fully up to date up to and during our installation, I needed to add another phone to my alarm system so called the support team and five minutes later it was all done. Truly fantastic. Thank you, NSS team.

We are very pleased with the service we have received from NSS team. Vin has been very prompt with everything we have requested and provided excellent support. From the installation guys- Mayan/Jay, admin support Bhavisha, to technical support team, they have all been a pleasure to work with. A great team! Thank you all for your hard work.
