Part ofCompanies House Forms UK

Updated June 2026 · England & Wales
If you run an unlimited company and you are bringing a new class of shares into existence, Form SH09 is the filing that tells Companies House about it. It sits slightly off the beaten path because most share allotment filings relate to limited companies, but unlimited companies have their own route and SH09 is it. The form captures the particulars of the new class, the rights attached to those shares, and the prescribed particulars that Companies House needs on the public register. On this page I walk through what the form does, when you need to file it, what information you will need to hand, and the wider context of operating as an unlimited company. If you want to sense-check your situation before you file, you can book a phone call with an experienced legal adviser at the bottom of the page.

What this document is

Form SH09 is the Companies House return used by an unlimited company when it allots shares of a class that did not previously exist in its share structure. It is the unlimited-company equivalent of the kind of return-of-allotment filing limited companies make, and it ensures the public record reflects the new class and the rights that come with it.

An unlimited company is a company registered under the Companies Act 2006 where the liability of members for the company's debts is not capped. That structure is less common than a company limited by shares or guarantee, but it is legitimate and can suit owners who value privacy of accounts and flexibility of capital over the protection of limited liability.

When such a company creates a brand new class of shares, SH09 records the number allotted, the nominal value, the currency, the amount paid up, and the prescribed particulars of the rights attaching to that class. Filing on time keeps the register accurate and avoids compliance headaches later.

How to use this document

  1. Confirm the allotment is properly authorised. Before touching the form, check that the directors have the authority to allot and that the articles allow the new class to be created. You may need a shareholder resolution to amend the articles or to grant allotment authority, depending on how the company was set up.
  2. Gather the class particulars. You will need the name you are giving the new class, the total number of shares being allotted in that class, the nominal value per share, the currency, and how much of the nominal value plus any premium has been paid up. Make sure your figures tie back to the board minutes and any subscription letters.
  3. Set out the prescribed particulars of rights. This is the heart of the filing. Describe the voting rights, dividend entitlements, rights on a return of capital, and any redemption or conversion features. Be precise, because these particulars become the public description of what the class actually does.
  4. Complete and check Form SH09. Fill in the company details, the date of allotment, and the particulars above. Cross-check names, numbers and dates against your statutory books. A small error here can mean a rejection and a second filing, which is avoidable if you slow down at this stage.
  5. File with Companies House within the deadline. Allotment returns are generally required within a month of the allotment date. Send the completed form to Companies House and update your register of members and statement of capital so your internal records match what is now on the public register.

Common questions

Q Who needs to file Form SH09?
SH09 is specifically for unlimited companies that are allotting shares of a new class. If you are a company limited by shares creating a new class, you would typically use a different return such as SH01 combined with SH08 for class naming. Because the form is structure-specific, it is worth confirming your company type on your Companies House record before you start.
Q What is the deadline for filing SH09?
Allotment returns under the Companies Act 2006 generally need to be delivered to Companies House within one month of the date of allotment. Missing the window can lead to enforcement action and keeps the public register out of step with your actual share capital, so it is sensible to diarise the filing as soon as the allotment is made.
Q Do I need a shareholder resolution to create a new class of shares?
In many cases yes. If the articles do not already provide for the new class, you will usually need to amend them by special resolution, and you may also need authority to allot. The exact requirements depend on the wording of your existing articles and any shareholders' agreement, so it pays to check these before the allotment.
Q What are prescribed particulars of rights?
These are the key features of the share class as recorded on the public register: voting rights, dividend rights, rights on a winding up or return of capital, and any rights to be redeemed or converted. They should be drafted carefully because they are the formal statement of what the class entitles holders to.
Q Does an unlimited company file accounts like a limited company?
Unlimited companies are often exempt from the usual requirement to file accounts at Companies House, which is one reason the structure is chosen. The exemption is conditional and does not apply in every case, for example where the company is part of a group containing a limited company. Check the current Companies House guidance before assuming it applies.
Q What happens if I make a mistake on SH09?
Companies House may reject the form and ask you to file a corrected version, or if the error is picked up later you may need to file a further document correcting the record. Errors in prescribed particulars are particularly awkward because they affect how the class is described publicly, so a careful check before submission saves time.
Q Can shareholders become personally liable for company debts?
In an unlimited company, yes. Members can be required to contribute to the assets of the company if it is wound up and cannot meet its debts. That liability is the trade-off for the flexibility and reduced disclosure the structure offers, and it is a key reason to take the decision to run an unlimited company seriously.
