Validation rules
61 rules, as counted from the PRA's published material. Software can run them exactly as published. Source
How they are written: Excel rule list with an expression column and severity per entry point; rules marked Include in XBRL are also XBRL formula assertions in the taxonomy package.
The rules, on bankofengland.co.uk
How they were counted
Rows in sheet 'structural_reform' of 'Bank of England Banking Taxonomy Validations Ringfencing v4.1.1.xlsx' (inside the validations ZIP, release 4.1.1) whose 'Severity and modules' column names RFB008. 61 rules: 61 active (Deactivated = no), 57 marked Include in XBRL = yes; 25 errors and 36 warnings. A rule shared by several entry points is counted once for each.
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
