National Security Inspectorate

NSI certification provides our customers with the reassurance that we are a reputable, compliant and trusted contractor and have been independently verified as meeting industry standards. NSI operates a two tier approach to approvals, which allows us to grow and develop our business whilst consistently developing the NSI reassurance to our customers:

Silver – designed for ‘Product Certification’ Refers to the ‘Product Certification’ against sector specific standards, e.g. BS7858, BS8243.

Gold – builds on product Certification to incorporate Quality Management System Certification. The combination of the Quality Management Systems and the relevant sector specific product or service represents the Gold standard of certification.  This level holds the greatest perceived value across industry and by the police, fire and rescue services and insurers.
