International Standards on Auditing (UK and Ireland)

The standards below are effective for audits of financial statements for periods ending on or after 15 December 2010 (unless otherwise stated). The FRC has published new versions of the auditing standards, effective for audits of financial statements for periods commencing on or after 17 June 2016.

Auditing standards for audits of financial statements include objectives for the auditor, together with requirements and related application and other explanatory material.
 
The International Standards on Auditing (UK and Ireland) (ISAs (UK and Ireland)) and International Standard on Quality Control (UK and Ireland) (ISQC (UK and Ireland)) are based on the International Standards on Auditing (ISAs) and International Standard on Quality Control (ISQC) of the same titles that have been issued by the International Auditing and Assurance Standards Board (IAASB), published by the International Federation of Accountants (IFAC) in 2009, and are used with the permission of IFAC.
 
ISA 700, “Forming an Opinion and Reporting on Financial Statements,” as issued by the IAASB has not been adopted.  The applicable standard issued by the FRC is ISA (UK and Ireland) 700, “The Independent Auditor’s Report on Financial Statements” which addresses the requirements of company law and also provides for a more concise auditor’s report.  The main effect of this is that the form of UK and Ireland auditor’s reports may not be exactly aligned with the precise format of auditor’s reports required by ISA 700 issued by the IAASB.  However, ISA (UK and Ireland) 700 has been designed to ensure that compliance with it will not preclude the auditor from being able to assert compliance with the ISAs issued by the IAASB.
