It is possible to start a new certificate application while your current certificate is valid, depending on the certificate. You can start new applications for the following modules/levels*.
| Module | Level | New certificate allowed from: |
| Supplier to Zero | Level 1 | 30 days before the expiration of the certificate |
| Supplier to Zero | Level 2 | 90 days before the expiration of the certificate |
* For other modules and levels, you can only start a new application after the expiration of the current certificate.
To start a level again, navigate to the evaluation of the respective level and click on 'Renew certificate'.
Note: The renewed certificate's validity starts as the certificate is awarded.
