The Financial Reporting Council (FRC) has issued a consultation on a proposed UK version of the International Standard on Sustainability Assurance (ISSA) 5000, “General Requirements for Sustainability Assurance Engagements”.
The consultation proposes ISSA (UK) 5000 for use on a voluntary basis by assurance providers. The FRC proposes alignment with the international standard in order to minimise burdens for firms carrying out assurance engagements across multiple jurisdictions. The profession-agnostic Standard supports application by both professional accountants and other assurance practitioners, provided they meet the relevant quality management and ethical requirements.
During its recent study of the UK sustainability assurance market, stakeholders expressed support for an assurance framework that provides a clear and internationally consistent approach to sustainability assurance.
Stakeholders are invited to comment until 31 July 2025 on the appropriate adoption of ISSA 5000 for the UK market by emailing AAT@frc.org.uk.
