The rule in plain words

What to do if your return fails it

1. 01Open the table below and find the cells the rule reads.
2. 02Add up the parts in your return and compare the result with the total.
3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
5. 05It runs only when your filing indicators mark IR.22.07 as reported.
6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The Bank’s own words and formula

The plain words above are the Bank of England’s own, word for word, from its list of validations.

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
