Audit regulation

Impact of Brexit on audit registration in UK and Ireland

Guidance issued prior to Brexit by ICAEW on audit regulation largely addressed the potential need for immediate action should withdrawal occur with no agreement, a no-deal Brexit. As a withdrawal agreement has been signed, the steps identified as part of a no-deal do not apply on 1 February 2020, but potentially will still come into force on 31 December 2020. This applies to arrangements both in the UK and Ireland.

Irish third country draft registration application

Auditors of UK companies (ie, companies incorporated in the UK) with listings on the Irish Stock Exchange, (such as listed debt), will be required to register with IAASA as third country auditors at the end of the transition period (31 December 2020) unless their registration continues to be accepted on the Irish audit register.
