The rule in plain words

Capital requirements for D&A undertakings equals to the sum of components

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.25.04 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example

With simple numbers.

Illustrative values
Solvency Capital Requirement including capital add-on1,200
Capital requirement for other financial sectors (Non-insurance capital requirements)800
Capital requirement for non-controlled participation requirements450
Capital requirement for residual undertakings300
Together2,750
What the rule then expects

Solvency capital requirement (consolidation method) must then be 2,750.

2,750Passes
2,850Fails

A file that reports 2,750 passes. One that reports 2,850 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
