Slot validation depends on the Golden Rules for Minimum Guarantee.
Your slot stats also affect your Client Performance Score.

If you have any issues when on slot please inform support.

If you receive a slot invalidation SMS but you think your slot should be validated (e.g. you got a puncture which delayed you), please complete the slot validation form within 24 hours of receiving the SMS.

For more serious matters (e.g. accident/hospitalisation), you can request slot validation after 24hrs but please apply ASAP to ensure correct validation.

⚠️ Fraudulent requests will be reviewed and may lead to termination of your partnership ⚠️

You will be asked to provide:

  • Proof: do you have enough proof to support your validation request?
  • Parameter: am I asking for the correct parameter to be validated?

Am I choosing the correct parameter?

The reason that your slot was invalidated will be shown on your invalidation SMS.
