Come and meet the team and attend one of our Application Workshops. Designed specifically to guide you through the application process and answer any questions you may have. For more information please contact the Applications team on 01628 764885 or view our training page.

If your business installs and maintains electronic security systems, you may wish to consider becoming an NSI approved company.

NSI is the leader in the field of providing inspection and approval services for companies operating within the security industry. Approval through an NSI scheme proves that you consistently meet high standards and reinforces the integrity of your company.

Gold or Silver – What is best for your business?

NSI’s schemes provide approval opportunities for all sizes of companies.  If you take achieving high standards seriously, then NSI approval is right for you


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.

Companies choosing to enrol in the Silver scheme will need to meet the required high level of technical competence but do not need to meet the requirements of ISO 9001.

The application zone provides you with further information on the NACOSS Gold and Systems Silver schemes and the necessary application forms you can download should you want to proceed.

NSI approved companies and applicants are able to also take advantage of an on-line subscription to BSI Standards for a nominal annual fee.
