Electronic Security Systems – Intruder Alarms – CCTV – Access Control

NACOSS Gold

NSI’s premier scheme for electronic security systems:

NACOSS Gold, is designed for companies that meet the industry’s highest standards by achieving business excellence through ISO 9001 Quality Management, as well as displaying technical expertise by meeting the appropriate British and European Standards.

Systems Silver

NSI’s Systems Silver scheme is designed for smaller or new companies and can be a stepping-stone for those wishing to progress to NACOSS Gold.


All Installers of Intruder Alarm, CCTV and Access Control systems install to the same technical standards and issue NSI Certificates of Compliance to customers, confirming the system is compliant with the respective standards and codes of practice.

For a system to be eligible for Police response, Police policy requires:

  • the system must be installed by an approved installer and awarded a Certificate of Compliance and

  • the Alarm Receiving Centre must be approved

Gold or Silver – What is best for you?

The NSI Electronic Security Scheme is a way for installers to gain an NSI  Certificate of Approval, and ability to issue Certificates of Compliance for systems they install for customers.

If your business installs and maintains electronic security systems, you may want to become an NSI approved company.

NSI’s schemes provide approval for all types and size of organisation.  If you take maintaining high standards seriously, then NSI approval is right for you.

Companies with Silver Approval meet the required high level of technical competence but not the requirements of ISO 9001.
