The SIA doesn't normally assess contractors directly: instead, we have partnered with a number of assessing bodies who do this for us.*

Private security companies who wish to become approved contractors using the Standard or Fast Track routes should contact one of these organisations to arrange an independent assessment. Please note: you will need to tell us on your application form (or subsequently) which assessing body you are using.

You should not proceed with any assessment for ACS until you have submitted an application to us and we have advised you to proceed.

Your chosen assessing body will also undertake annual re-verification assessments as part of the process for maintaining your approved status.

The assessing bodies we are partnered with are:

• BSI (0845 080 9000)
  Contact: Certification Sales Department
  
  
• Chamber Certification Assessment Services Ltd (01543 255 144)

• NQA (01582 539000)
  Contact: Clare Welstead
  
  
• SSAIB (0191 296 3242)

You will need to pay your chosen assessing body to carry out an assessment to SIA requirements - please note that the SIA does not set these fees. However, we have provided general guidance on how long an assessment should normally take.

*In exceptional circumstances we may decide to carry out an assessment directly. In such cases we will contact you to discuss how and when this might be arranged.
