What is an SH01 form?

The SH01 form, or "Return of Allotment of Shares", is a legal document that UK companies must submit to Companies House whenever they issue new shares.

When would I need to file an SH01?

You need to file an SH01 form with Companies House every time you issue new shares, such as during a funding round or when granting equity to co-founders, or if there's any change to the issued share capital of the company (e.g., issuing more shares of a particular class). However, if you're dealing with share options, an SH01 is not required.

How to File SH01?

  • Register with Companies House: Obtain an authentication code sent to your company's registered office (or request it be sent to your home address).

  • Download and Complete SH01: You can download the SH01 form as a PDF. It requires details such as:

    • Number of shares issued
    • Nominal value
    • Class of shares
    • Amount paid or unpaid on each share

Where to submit?

Once completed, you can submit the form online or by post.
