Own funds and 2 other templates: values must agree (IR.23.01, IR.23.02, IR.23.03, Bank of England rule IR_bv0829)

A blocking check on the own funds (IR.23.01), detailed information by tiers on own funds (IR.23.02) and annual movements on own funds (IR.23.03) templates, in the quarterly group (QRG) and annual group (ARG) returns.

The rule in plain words

The "Total" value of the item reported in column "Total" reported in Own funds (IR.23.01.04.01) should be equal to the sum of the same item of "Tier 1 - unrestricted" and "Tier 2"

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark IR.23.01 as reported.
