11 days between signing and publication
Signing is recorded on 2025-09-29 and publication on 2025-10-10, an interval of 11 days. Recorded dates may need correction; this calculation does not establish a legal breach.
Question for the public body
What explains the gap between the recorded signing and publication dates?
Documents and records to verify
Check both dates against BASE and the signed contract. Ask when the record was submitted and whether it was corrected.
The supplier’s identification is incomplete
The record names no supplier, or one supplier has no tax identifier. This describes incomplete data, not the absence of an award recipient.
Question for the public body
Which supplier and tax identifier appear in the original contract, and why are they missing from the record?
Documents and records to verify
Open the contract and award documents. Ask the public body to identify the recipient and correct or explain the missing fields.
This observation does not establish favouritism, illegality or loss. Verify the documents and seek the public body’s explanation before publishing.
