Context
The FRC has published final revisions to UK standards on using the work of an auditor’s expert. The FRC revised one UK auditing and one UK assurance standard to maintain alignment with changes made to equivalent international standards issued by the International Auditing and Assurance Standards Board (IAASB). Having single sets of standards which can be used across multiple jurisdictions helps reduce costs for companies in meeting reporting and audit obligations and supports quality and consistency of audit and assurance.
Key points to note and next actions
The FRC has revised ISA (UK) 620 (Revised September 2026) – Using the Work of an Auditor’s Expert and ISAE (UK) 3000 (Revised September 2026) – Assurance Engagements Other Than Audits or Review of Historical Financial Information, to reflect updated ethical requirements in the IESBA Code for using external experts.
The main points include:
- The revisions align audit and assurance standards with new ethical rules on external experts.
- They clarify how practitioners should assess an expert’s competence, capabilities and objectivity.
- They reinforce the need for clear responsibility, evaluation and documentation when relying on expert work.
- The revised standards apply from 15 December 2026.
