Guidance

SIA approved contractors using overseas suppliers

What you must do if you use overseas suppliers to deliver services in the UK.

Your company might use overseas suppliers to deliver services in the UK. For example, you might use them to monitor CCTV footage of a location in the UK. Or you might use them for ‘back-office’ services like payroll.

As an SIA approved contractor, there are certain things you must do if you use overseas suppliers.

What you must do

If you deliver services using overseas suppliers, you must:

  • tell us
  • tell your customers
  • obey data protection and privacy laws about transferring information out of the UK – this includes conducting a data protection impact assessment

Your business activities in the UK must always meet the ACS standard. This still applies if you use overseas suppliers to deliver services in the UK. You can read the ACS standard on pages 21-24 of Get Approved.

You risk losing your ACS approval if you do not meet the standard.

What we will do

Your ACS assessor will check that you have done your data protection impact assessment.

We will also add the following statement to your entry on our register of approved contractors:

This company uses overseas suppliers that have not been approved by us and are not covered by the scope of this approval. Customers should seek their own assurance of any overseas provision.
