Where the list was read: Source
Validation rules
The PRA publishes the checks it runs on this return. They could not be counted from the published material. They are written for people to read; software cannot run them as published. Source
How they are written: EBA validation and filing rules for the taxonomy version in use, applied by RegData.
The FCA page says RegData implements the validation and filing rules specified by the EBA, with EBA blocking rules set to ERROR (file rejected), non-blocking rules to WARNING and deactivated rules ignored. The PRA says it has implemented EBA taxonomy 3.0 from 1 January 2022 (2.10 for COR013). Reporting (CRR) Annex XV only states the criteria the rules must meet.
How they were counted
Not counted: the PRA applies the EBA validation rules of the taxonomy version in use, and does not republish them as its own list.
Counts are in the PRA's own unit, so they are not comparable with other regulators' counts.
Public data
No published data from this return was found. No publication of this data, firm by firm or added up, was found on the Bank of England pages read. The PRA does not publish individual firms' returns. Source
Official documents (7)
The PRA's own files, with the size and SHA-256 fingerprint of each as downloaded on 11 November 2026, so anyone can tell whether a copy is the same version.
