XBRL UK LIMITED

What XBRL UK LIMITED does

XBRL UK Limited is a non-profit private company (Company Number 4958719) operating as the UK jurisdiction of the XBRL International consortium. The organisation promotes the XBRL (eXtensible Business Reporting Language) standard for digital company reporting in the UK and provides technical guidance, taxonomies, tagging samples, white papers, and member services to UK companies, banks, government agencies, accountants, software vendors, and academics adopting XBRL. It is facilitated by the Institute of Chartered Accountants in England and Wales (ICAEW) and is headquartered in London.

Its core technology contributions are the Inline XBRL Specification (developed and edited by Chairman Philip Allen), which is mandated for HMRC Company Tax filings, and the UK-specific XBRL taxonomies covering UK GAAP, UK IFRS, Banking, and Charities reporting requirements. These were originally developed by XBRL UK and transferred in 2013 to the Financial Reporting Council (FRC). The organisation also publishes the Preparers and Developers Guide, detailed tagging documentation, and educational white papers. The combined HMRC mandatory programme and Companies House voluntary programme have generated over six million XBRL documents to date, with 1.9 million UK companies filing accounts and tax returns in XBRL annually.

XBRL UK's business model is membership-based. Annual fees are tiered by organisation size: £5,000 for organisations with more than 100 staff, £2,000 for 21-100 staff, £1,000 for 11-20 staff, £500 for 10 or fewer staff, and £100 for academics and unaffiliated individuals. Membership automatically confers XBRL International consortium membership, access to technical working groups, early visibility into XBRL projects and taxonomies, direct contact with XBRL software vendors, and participation in XBRL Europe's twice-yearly events. The organisation is governed by a small team led by Chairman Philip Allen (also Executive Chairman of CoreFiling) and Director Peter Calvert, with operational support from ICAEW.
