Supplier to Zero V2 was published on 31 July 2026.
A six-month transition period applies from 1 August 2026 to 31 January 2027. During this period, both Supplier to Zero V1 and V2 will remain available, allowing facilities to familiarise themselves with the revised framework and transition in line with their certification renewal cycle.
From 1 February 2027, Supplier to Zero V2 will become mandatory. From this date:
All new Supplier to Zero assessments and certifications must be completed against V2 requirements.
Supplier to Zero V1 will be discontinued.
Existing V1 certificates issued before 1 February 2027 will remain valid until their stated expiry date.
Facilities do not need to transition to Supplier to Zero Version 2 until their existing Version 1 certificate expires. All Version 1 certificates issued before the mandatory transition date will remain valid until their stated expiry date. When a certificate is due for renewal, the facility must complete its next assessment against Supplier to Zero Version 2.
