SIA Approved Contractor Scheme
 

Choose NSI As Your ACS Assessing Body

NSI is an appointed Security Industry Authority (SIA) Approved Contractor Scheme (ACS) Assessing Body and has been since the ACS was introduced in 2006. If you are a security company that is eligible to become an Approved Contractor, NSI would welcome the opportunity to become your Assessing Body.

Why Choose NSI As Your SIA Assessing Body?

  • Our fees are competitive.
  • We conduct audits thoroughly and robustly, bringing to your attention issues that will benefit your company.
  • We are an experienced inspection body that has provided approval and certification services for security companies for nearly 40 years.  Our expertise is working with security companies and we believe we can understand your specific needs.
  • Our inspectors are fully qualified auditors, who have exceptional knowledge of security companies and the security industry and will therefore bring added value to your ACS assessment.
  • NSI Guarding Gold or Cash Services Gold approved companies can take advantage of the benefits of achieving ACS approval using the NSI Passport route.  If you are not an NSI Guarding Gold or Cash Services Gold approved company, then you can apply to us now to become one. More
  • If your company is assessed by NSI, you may find that you are a preferred choice of customers and specifiers who wish to use security companies that they know have been audited by the UK’s leading security industry approvals body.
  • If you choose NSI as your Assessing Body, you can select one of three routes to ACS approval - Standard, Fast Track and Passport. NSI were the first Assessing Body to provide the Passport route, which offers a cost saving opportunity to those companies who choose NSI Gold approval.
