Unlimited company (or Welsh (cwmni) anghyfyngedig). There is no limit on the liability of its members. It is not a requirement under company law to add or state the word or designation Unlimited or its abbreviations (Unltd., or Ultd.) at the ending of its legal company name, and most such companies do not do so. Unlimited companies are exempted from filing accounts with the Registrar of Companies for public disclosure, subject to a few exceptions (unless the company was a qualified subsidiary or a parent of a limited company during the accounting period).
In this case, you need to write a remark about that circumstance on the Business Property Statement, or on an attachment to it. Also fill out Part III (Equipment Belonging To Others) of the form. If you own any small equipment, such as a printer, copier, etc., that you are using in the business, you should report these costs under Part II of the Business Property Statement and also Schedule A.
