The evidence validation review consists of reviewing uploaded documentation against the GRESB Validation Requirements. During the 1-hour call, you will have the opportunity to discuss the findings and, ask for additional guidance and clarification on the GRESB Assessment indicators. After the call, you will receive a feedback report highlighting the correctness and completeness of the data.
The Pre-Submission Check does not exclude you from any element of the validation process, nor does it guarantee a better GRESB Score. It is intended to ensure you have not overlooked details in your submission.
For more information about the Manual Evidence Validation process, see here.
- Pre-Submission Checks for all GRESB Assessments can be requested from April 1 until June 20, with Pre-Submission Checks scheduled from May 1 until June 26.

You can request a Pre-Submission Check in the portal, at any time after you start an Assessment. At the time of request and after payment, you will be prompted to schedule a time for a 1 hour call with 1-2 staff from the Pre-Submission Check team.
Make sure your Assessment is complete at least 1 week before the call so that the Pre-submission Check team has sufficient time to review your Assessment before the call. If your Assessment is not complete at the time of review, the Pre-Submission Check team will only review completed indicators.
After the call, you will receive a feedback report that you can use to review and revise your Assessment before submission. You can also choose to only receive a feedback report, without a call.
We strongly encourage participants to place their request and schedule their call as early as possible because there are a fixed number of appointments and it is not uncommon for requests to surpass availability.
Calls can be booked from within the GRESB Portal from April 1 until June 20, and checks can be scheduled between May 1 and June 27, subject to available time slots.
