What do NSSG offer as approved contractors?

Being a well-regarded and respected specialist security service in London, the M25 and the home-counties; understanding urban and suburban security needs is second nature to us. As a result we are experts in manned security for developments, construction sites, commercial building and operating warehouse alarm systems in London and the surrounding areas.

This means our company has met 89 different performance indicators which are based on widely recognised business improvement models (including ISO9001:2000 and the European Foundation for Quality Management Excellence Model). The scheme also draws upon Investors in People and the applicable British Standards e.g. BS7499 and BS7858.

There is no standard way to issue quality manned security. That is why at NSS our professional manned security guard service offers you bespoke on-site security tailored to your business. We work with you to understand your needs and you want to see patrols managed; where, when and how often for example. Then you can be at peace knowing that your site is in safe hands. In fact our confidence in the quality and satisfaction of our manned security guard service is so high, that we offer a no-nonsense guarantee where you can terminate your contract at any time without any risk of liability on your part.

The Benefits Mobile Patrols

Perhaps your business does not require permanent stationed guarded security but does require some intermittent security check to ensure that the place is secure. If this is the case then perhaps NSS’s Mobile Patrol services is the solution that may work better for your business. Our mobile manned security assigns one of our highly trained professionals to a vehicle based patrol to visit your site at set and agreed times of the day. Should there have been an intrusion or attempted break-in, our fully prepared staff will contact the police or the emergency services in the event of a fire or flood.
