When must a site have its first SIZA audit after registration? 

SIZA does not prescribe when sites must have their first audit after registration on the SIZA Platform.  A site can remain a provisional member of SIZA on the system until it has a third party audit.  After the audit the site becomes a full member as its SAQ information will have been verified in the audit process.  The site then gets into the SIZA Audit Frequency cycle according to the SIZA-Audit-Frequency-Matrix-October-2018. There is no prejudice to growers in being a provisional member. 

Can I choose any Ethical Audit Company to do a social audit? 


Due to global market requirements, all audit companies and auditors will need to be registered with the Association of Professional Social Compliance Auditors (APSCA), by 1 February 2019.  The registration number of the Auditor and the Audit Entity must be visible on all Audit Reports after the given deadline.

As from the 1st of October 2016 only ethical audits done by Tesco approved audit bodies will be accepted (Tesco approved audit Companies for SIZA).

 Those companies are the following: 

  • Control Union
  • NSF
  • SGS
  • Intertek

When must a site do its next audit if they did a SIZA audit?

The next audit of these sites will be based on the SIZA-Audit-Frequency-Matrix-October-2018 and depends on the number of non-compliances which have not been completed and signed off as agreed to in the Corrective Action Plan Report. After the final date for completing non-compliances has passed, the site will be sent a letter indicating its risk rating and when their next audit will be due.
