Section 12 / RCDEN completes

Issued form · page 6

RCDEN’s registration review

RCDEN records the baseline checks and any conditions on registration.

When this applies

Suppliers leave this section for RCDEN. Registering a supplier is separate from approving a particular activity.

Help with this section

Open a question for help. The numbers match the printed questions and agreement clauses.

12.1

Review record

+

What to enter

Reference the identity/ownership, sanctions and relevant evidence checks, with the date. Retain the underlying review record rather than copying sensitive details into the form.

Where to find it / what to do next

  1. RCDEN completes this review. Record the checked legal entity, relevant ownership, sanctions and evidence results with the review date.
  2. Confirm uncertain or conflicting evidence through the relevant issuer or authority rather than treating a missing search result as a final decision.

12.3

Reviewer and review trigger

+

What to enter

Record the reviewer’s name, role and date, and the next review date or trigger. Material changes and relevant expiry dates can require updated evidence without a fresh agreement.

Before you move on

The agreement is executed on page 8. An accepted order and required activity-specific assurance or permissions are still needed before the affected activity.

Have these ready

  • Current checks appropriate to the registration.
