1 min readBlockingBank of England taxonomy 2.2.0Updated 11 November 2026

Life income and expenditure and 2 other templates: a conditional check (IR.05.03, IR.05.04, IR.31.01, Bank of England rule IR_bv0175)

A blocking check on the life income and expenditure (IR.05.03), non-life income and expenditure (IR.05.04) and outwards reinsurance balance sheet exposures (IR.31.01) templates, in the annual solo (ARS) and annual third-country branch (ARB) returns.

The rule in plain words

‌The sum of the values in "Reinsurers’ share of Premiums written" (C0200) on template IR.31.01.01, should equal the value in "Total life and health" for "Reinsurers’ share" in template IR.05.03.01 plus the value in all business for "Gross Premiums Written" (R0110C0015 + R0110C0525 + R0110C0545) in template IR.05.04.01 minus all business for "Net written premiums" (R0160C0015 + R0160C0525 + R0160C0545) on IR.05.04.01

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.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark IR.05.03, IR.05.04 and IR.31.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
