The Financial Reporting Council (FRC) is committed to acting as a proportionate and principles-based regulator that balances the need to minimise the impact of regulatory requirements on business, while working to support the delivery of high-quality audit and assurance work to maintain investor and wider stakeholder confidence in audit and assurance.
This consultation seeks stakeholder views on revisions to two UK auditing and assurance standards:
- ISA (UK) 620 'Using the Work of an Auditor's Expert'
- ISAE (UK) 3000 'Assurance Engagements Other than Audits or Reviews of Historical Financial Information'
The revised versions of these standards are being consulted on to reflect recent narrow scope amendments made to the equivalent international standards, which have recently been issued by the International Audit and Assurance Standards Board (IAASB).1 These amendments respond to the International Ethics Standards Board for Accountants’ (IESBA) recently approved revisions to its International Code of Ethics for Professional Accountants (including International Independence Standards)—the IESBA Code—which introduced, among other provisions, explicit ethical requirements for using the work of external experts in audit, assurance, and non-assurance engagements. The IAASB’s updates reflect ongoing collaboration and coordination between the IAASB and IESBA and help to maintain interoperability between the IAASB standards and the IESBA Code. Adoption of these standards is necessary to maintain equivalence between UK and international auditing standards.
Responses should be received by Friday 10 July 2026.
