Verified data can easily be shared from one Accredited Host (AH) to another via the Gateway. You only need to complete your assessment on one AH. The questions and the process are the same on all the AHs.
Once the SLCP assessment process is completed and you have access to your verified data, you can share this data, via the Gateway, with any other AH. The other AH will receive the complete verified data set and can share this, with your permission, with an end-user, e.g. a brand that wants to download the data from a specific AH.
You do not need to complete the SLCP process on the same AH that the client wants to use to download their verified data. You can complete the process on another AH, and share it with the other AHs after the assessment has been verified and finalized.
