Who will check whether you are applying the FCA Standard correctly?
Not OVOCOM but an independent certification body (OCI) will take charge of the control. An independent control is essential. Only certification bodies, approved by OVOCOM are allowed to perform FCA-audits.
The approved certification bodies are required to comply with the strict quality criteria. In order to monitor the later, OVOCOM itself will carry out audits (office and witness audits) on a regular basis. You are free to choose a certification body whom you wish to appeal to.
In addition, auditors approved by OVOCOM shall run through an individual approval procedure. They are for example required to pass a biennial FCA exam.
