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.
The form records details of the shares that have been allotted, including the number and class of shares, nominal value, and the amount paid or unpaid on each share.
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 following 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).
An SH01 is not required when granting share options, as options do not create new issued shares until they are exercised.
Companies House must be notified of an allotment of shares within one month of the date of the allotment.
How to generate an SH01 in FounderCatalyst
Once your funding round has been completed, FounderCatalyst can generate ready-to-file SH01 forms for you.
To generate your SH01 forms:
-
Go to the Cap table section
-
Select SH01 from the Download dropdown in the top right-hand corner.

-
The platform will show you a list of the shareholders for whom an SH01 can be generated.
-
Select one or more, and click download to create the SH01 forms.
The forms will be generated and downloaded immediately.
Your generated SH01 forms will also be saved in your Data room, so you can access them again later if needed.

If you’d prefer to complete the SH01 manually, or want to understand what each section of the form requires, see our article: Form SH01: what is it and how do I complete and file?
Please note: FounderCatalyst generates the SH01 forms based on the information held in your funding round. You should review the forms carefully before submitting them to Companies House and make sure the information is correct.
Where to submit
Once you have generated and reviewed your SH01 forms, you are responsible for submitting them to Companies House. FounderCatalyst does not submit the SH01 to Companies House on your behalf.
You can submit your SH01 online or by post.
