Minimum capital requirement - only life or only non-life activity: values must agree (IR.28.01, Bank of England rule IR_bv0617)

A blocking check on the minimum capital requirement - only life or only non-life activity template (IR.28.01), in the annual solo (ARS) return.

The rule in plain words

The MCR cap reported in Minimum Capital Requirement (IR.28.02.01.05) - Both life and non-life insurance activity should be equal to 45% of the SCR

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.28.02 as reported.
