Check your iXBRL accounts

Use this service to check your iXBRL accounts are valid and meet the iXBRL specification and business validation rules.

You can use this service to check:

• single instance Financial Reporting Council (FRC) Taxonomy filings – if the file is valid, you can also preview the image that will be published on the Companies House register
• zip file submissions, including UK Single Electronic Format (UKSEF) Taxonomy submissions and Welsh/English dual submissions

Read the Technical Interface Specification (TIS) for more information on validation rules.

You can find details of all available taxonomies and guidance for filers and developers on the Financial Reporting Council (FRC) website.
