Filing History - Zip file

We have come across a company where the accounts filed, are a zip file containing a document which is described as a XHTML.

Company Number: 00031461
Filing: 29/01/2026 Group of Companies Accounts

Are you able to confirm what filing types are available to be uploaded to the register, as we will need to make necessary changes when we call the API to accommodate. Or if already documented on the API documentation, can you please point me in the right direction. Thanks

Hi @sharon.case

Please see which types of package accounts can be filed using our ZIP file service - File package accounts with Companies House.

Thanks,
