The UK has its own Inline XBRL format and taxonomy, the UK Single Electronic Format (UKSEF), which is a variant of the European Single Electronic Format (ESEF). In CtrlPrint you can report in accordance with the UKSEF.


The UKSEF taxonomy released by the Financial Reporting Council adds UK-specific elements to the ESEF taxonomy. The most interesting addition is the inclusion of the UK’s Streamlined Energy and Carbon Reporting (SECR) requirement, integrating Inline XBRL-based carbon disclosures with financial reporting.

From January 2021, it became mandatory for UK companies to comply with ESEF requirements. In Phase 1 of their compliance, which involved annual reports to be published in 2022, UK companies were required to apply machine-readable XBRL tags only against primary financial statement disclosures. In Phase 2, which is related to annual reports due in 2023, the companies also need to tag notes to the annual financial statements.
