The new UK accounting standards are mandatory for accounting periods beginning on or after 1 January 2015. Early adoption is permitted.

UK and Irish company law each recognise two financial reporting frameworks:

  • adopted IFRS and a framework based on specific company law requirements
  • accounting standards set by a prescribed body (the FRC).

The latter framework is UK and Ireland GAAP (generally accepted accounting practice). Publicly listed companies are required to apply adopted IFRS in the preparation of their group accounts but may choose between adopted IFRS and UK and Ireland GAAP for the preparation of their individual parent accounts. Other entities have a choice between the two frameworks.

Relevant applicable FRC latest standards can be accessed from the following list:

  • FRC guidanceOverview of the financial reporting framework application of Financial Reporting Requirements, describes the financial reporting framework applicable for accounting periods beginning on or after 1 January 2021 (early application is permitted subject to the provisions in each standard).
  • FRS 100Application of Financial Reporting Requirements, sets out how the new regime will work. It explains:

- which standards apply to which types of entity

- when an entity can apply the reduced disclosure framework

- when an entity should follow a Statement of Recommended Practice (SORP)

- transition arrangements.

A new edition of FRS 100 will be issued following changes to this standard expected later this year.
