International Standards on Auditing (UK) (ISAs (UK)) and the International Standard on Quality Control (UK) (ISQC (UK)) include objectives for the auditor, together with requirements and related application and other explanatory material. ISAs (UK) and ISQC (UK) are effective for audits of financial statements for periods commencing on or after 17 June 2016 (unless otherwise stated).

The Financial Reporting Council issues Statements for Reporting Accountants that establish basic principles and essential procedures, with related guidance, for accountants on assurance engagements closely related to an audit of financial statements. Currently there is one such standard - International Standard for Review Engagements (ISRE) (UK and Ireland) 2410, published in 2007, which applies to the auditor of an entity reviewing interim financial statements issued by the entity:
