How Do You Register a Company in the UK?
Company registration in the United Kingdom is governed by the Companies Act 2006, with Companies House serving as the official regulatory authority overseeing the incorporation and operation of companies. Below is a step-by-step guide to the UK company registration process:
1. Choose an Appropriate Business Structure
The first step in registering a company is selecting the appropriate legal structure. This decision should be based on the nature of the business, the number of members or partners, and the scope of operations. Common structures include private limited companies (Ltd), limited liability partnerships (LLPs), and sole proprietorships.
| Pro Tip: Your LLP’s name should reflect its business activity and be easy to read and remember. It’s also important to consider your website domain—ideally, it should include the LLP’s name for consistency and brand recognition. |
2. Conduct a Company Name Search
Once the business structure is determined, the next step is selecting and verifying a company name. The proposed name must comply with the Companies Act 2006 and should not infringe on any existing trademarks as per the Trademarks Act. Business owners should use the Companies House online name availability checker to ensure the name is unique and permissible.
3. Appoint Directors and Key Personnel
Every company must have at least one director to manage its operations. A shareholder can also serve as a director. While appointing a company secretary is optional, it is essential to designate key officers, such as a compliance officer if applicable. The service addresses and personal details of all directors must be submitted as part of the incorporation application.
4. Identify People with Significant Control (PSC)
Applicants must identify People with Significant Control (PSC)—individuals who hold more than 25% of shares or voting rights or otherwise exert significant influence over the company. This information must be maintained in a PSC register and submitted to Companies House during the registration process.
5. Prepare the Required Legal Documents
Two critical documents must be prepared:
- Memorandum of Association (MOA): A legal statement signed by all initial shareholders or guarantors agreeing to form the company.
- Articles of Association (AOA): A document that outlines the internal governance, rules, and regulations of the company.
6. Submit the Registration Application
The applicant must select a Standard Industrial Classification (SIC) code that best describes the company’s primary business activities. Registration can be completed online through the Companies House website, via post, or with the assistance of an authorised agent.
Applicants can simultaneously register for corporation tax with HM Revenue & Customs (HMRC). If not done during incorporation, registration must be completed separately after the company is officially formed.
Upon successful registration, the company will receive a Certificate of Incorporation, which serves as official proof of legal existence and includes the company’s registration number and date of formation.
You must open a corporate bank account and consider hiring professional accountants to assist with annual filings, tax compliance, and financial management. Additionally, determine whether your business operates in a regulated sector, such as food services or healthcare, which may require specific licenses or permits. These must be obtained before you can legally commence business operations.
