The official record
What the firm itself reports to the regulator, scoped to banking and credit complaints only. This is a different measure from the decisions above — it covers all complaints a firm received, not only those that reached an ombudsman. Firms report on periods set by the regulator, which are not always the calendar half-year the file was published under (shown below where they differ). No period-over-period change is calculated here — these are the reported figures only. See the scorecard for all three measures side by side.
| Source | Period | Upheld | Opened | Closed | New cases |
|---|---|---|---|---|---|
| FOS | 2025-H2 | 38.3% | — | — | 100 |
| FOS | 2025-H1 | 40.6% | — | — | 47 |
Decisions are attributed to a firm only where the decision text names it unambiguously. Where a name could refer to more than one firm, the decision is left unattributed rather than guessed, so these counts are a floor, not a total. Method.
