The Annual Safeguarding Audit Under CASS 15: What Auditors Test and Where Firms Fail

Regulatory Counsel · Published August 2026 · Last reviewed August 2026 · 12 min read

Key Takeaways

  • The safeguarding audit is an assurance engagement on the firm’s compliance with the safeguarding rules, not a financial statement audit, and it is reported to the FCA.
  • Auditors test the design and the operating effectiveness of controls across the full period, not the position on a single date.
  • The most common causes of a qualified opinion are incomplete records, reconciliations that cannot be reproduced, unresolved discrepancies and undocumented acknowledgement letters.
  • Evidence must be contemporaneous. Reconstructing reconciliations during fieldwork is itself a finding.
  • Firms should run an internal readiness review at least one quarter before the audit period ends.

Under the interim safeguarding regime delivered through the CASS 15 sourcebook, the annual safeguarding audit has become the principal external test of whether a payment institution or e-money institution is actually protecting relevant funds, as opposed to describing how it intends to.

The audit is uncomfortable for firms whose processes rely on manual workarounds, because it tests operation across a period rather than position on a date.

What the audit is

It is an assurance engagement performed by a qualified auditor, resulting in an opinion on the firm's compliance with the safeguarding requirements over the audit period. The opinion is provided to the firm and submitted to the FCA. Two outcomes matter.

Unqualified opinion. The auditor concludes that the firm complied with the requirements in all material respects throughout the period.

Qualified or adverse opinion. The auditor identifies breaches or is unable to obtain sufficient evidence. This is visible to supervision and will generate follow-up.

What auditors test

AreaWhat is testedTypical evidence
Organisational arrangementsGovernance, roles, senior manager ownership, policy currencySafeguarding policy, board minutes, responsibilities map
Identification of relevant fundsWhether all in-scope funds are identified at receiptProduct and flow mapping, system configuration
SegregationTimeliness of transfer into a safeguarding accountTransaction level testing across the period
Records and accountsAbility to reproduce the position at any dateRelevant funds records, historic extracts
Internal reconciliationFrequency, method, completenessDaily reconciliation files with preparer and reviewer
External reconciliationAgreement to third-party statementsBank and institution statements, matching evidence
Discrepancy handlingIdentification, funding, escalation, resolutionException log with dated entries
Third-party arrangementsAcknowledgement letters, account designationSigned letters, account naming evidence
Wind-down and distributionAbility to return funds promptlyDistribution plan, tested extract

The audit is period-based. A firm that performed reconciliations correctly for ten months and inconsistently for two has a finding.

Where firms fail

Records that cannot be reproduced. If the relevant funds position as at a date three months ago cannot be regenerated from the system, the record is not adequate.

Reconciliations without evidence of review. A completed reconciliation with no preparer, no reviewer and no timestamp cannot be relied on.

Discrepancies left open. An exception log with items open for weeks, without escalation, demonstrates that the resolution process is not operating.

Late segregation. Funds transferred to the safeguarding account on a delayed basis, even briefly, are tested transaction by transaction.

Missing or defective acknowledgement letters. Letters that are unsigned, out of date, or that do not correctly describe the account and the firm's interest are a recurring finding.

Agent and distributor flows. Funds received through agents or distributors are frequently outside the primary reconciliation, and that omission is normally material.

How to prepare

Run a readiness review one quarter before period end covering four questions.

  • Can we reproduce the relevant funds position for any date in the period, from system records, without manual reconstruction?
  • Does every reconciliation in the period have evidence of preparation, review and resolution of exceptions?
  • Are all safeguarding accounts correctly designated, with current acknowledgement letters on file?
  • Are all product and distribution flows, including agents, in scope of the reconciliation?

Where the answer to any is no, remediate before period end rather than during fieldwork. Our PS25/12 safeguarding compliance checklist and our CASS 15 reconciliation guidance set out the control detail, and the safeguarding software buyer's guide covers tooling.

Governance around the opinion

The board should receive the audit report, the management letter and a tracked remediation plan. Where the opinion is qualified, the board should record its consideration, the root cause and the corrective action, and should expect supervisory contact. Firms that self-report a qualified opinion with a credible plan are in a materially stronger position than firms that wait to be asked.

Frequently Asked Questions

It is an assurance engagement in which a qualified auditor forms an opinion on whether the firm complied with the safeguarding requirements throughout the audit period. The opinion is provided to the firm and submitted to the FCA.

The most common causes are records that cannot reproduce the historic relevant funds position, reconciliations without evidence of review, unresolved discrepancies, late segregation of funds, and missing or defective acknowledgement letters.

A period. The auditor tests the design and operating effectiveness of controls across the whole audit period, so inconsistent performance in any part of the period can produce a finding.

Issues can be corrected, but reconstructing records or reconciliations during fieldwork does not remove the finding, because the evidence is no longer contemporaneous. Remediation should be completed before period end.

Receive the report and management letter, record its consideration and challenge, approve a tracked remediation plan with owners and dates, and where the opinion is qualified, consider self-reporting to the FCA with that plan.
