The ACS, NSI and You

Choosing NSI as your SIA Assessing Body

Standards within the security industry have never before received so much attention.  The proliferation of unscrupulous and poor performing companies attracts the attention of your customers.  There has never been a more important time for security companies to prove their quality and probity.

NSI has operated voluntary approval schemes for many years for security companies who want to demonstrate to their customers that they work to the highest standards.

In 2003, the Security Industry Authority (SIA) was created as a result of the Private Security Industry Act (2001) with a mission "to help protect society by collaboratively developing and achieving high standards in the private security industry".

The Act required the SIA to establish a "system of inspection for providers of security services, under which those organisations who satisfactorily meet the agreed standards may be registered as approved, and may advertise themselves as such".

The SIA consequently introduced the Approved Contractor Scheme (ACS) for manned security companies and others.  Assessments are required to be conducted on behalf of the SIA by third-party Assessing Bodies such as NSI.

If you are not approved by NSI, you can still choose us as your SIA Assessing Body.
