Registering a limited company creates a separate legal entity that can own property, enter into contracts and incur debts in its own name, distinct from its shareholders. Shareholders’ liability is generally limited to the amount they have invested. Failing to register correctly can result in delays, penalties from Companies House, and potential issues with HMRC. This article will explain the step-by-step process of registering a limited company in the UK.
What is a Limited Company?
A limited company is legally separate from the people who own it. This means the company can own property, sign contracts, owe money and take legal responsibility in its own name.
Every limited company must have at least one director. The director is responsible for running the business and making decisions for the company. Shareholders usually only risk the money they have invested in the company.
However, this protection is not always viable. Directors or shareholders may still be personally responsible in some situations, such as if they personally guarantee a company’s debt, trade when the company cannot pay its debts, or fail to meet their legal duties as directors.
Types of Limited Companies
Private Limited Company (Ltd)
A private limited company is the most common structure for small and medium-sized UK businesses. Shares in a private company cannot be offered to the general public. Most businesses registering for the first time choose this structure.
Public Limited Company (PLC)
A public limited company can offer shares to the public and list on a stock exchange. PLCs must maintain a minimum share capital of £50,000 and meet stricter regulatory requirements than private companies.

Step-by-Step: How to Register Your Limited Company
1. Choose a Company Name
Your company name must be unique. You can check availability using the Companies House online search tool before submitting your application.
Private company names must end with “Limited” or “Ltd”. Public company names must end with “Public Limited Company” or “PLC”. Certain words and expressions require prior approval before you can use them, including “Royal”, “British” and “Authority”.
2. Appoint Directors and Consider a Company Secretary
You must appoint at least one director aged 16 or over. Directors are legally responsible for running the company and ensuring it complies with all applicable legal requirements. When registering, you will need to provide each director’s full name, date of birth, nationality and residential address.
Private limited companies are not legally required to appoint a company secretary, although many choose to do so for help managing administrative obligations. Public limited companies must appoint a qualified company secretary.
3. Register a Registered Office Address
Your company must have a registered office address in the UK. Companies House and HMRC will send all official correspondence to this address, including your authentication code. You can use your home address, business premises or a professional registered office service. Bear in mind that the registered office address appears on the public register, so consider privacy implications if you plan to use a personal address.
4. Decide on Share Structure
You need to determine how many shares your company will issue and at what value. A common starting point is 100 ordinary shares at £1 each, giving a total share capital of £100.
You must identify all shareholders and record how many shares each person holds. Shareholders own the company and hold rights, including voting on major decisions. You can also issue different classes of shares with different rights attached, such as ordinary shares and preference shares.
5. Prepare Your Memorandum and Articles of Association
The memorandum of association is a legal statement signed by all initial shareholders confirming their agreement to form the company. The articles of association set out the written rules for how the company will be governed, managed and operated.
When you register, Companies House will automatically apply the Model Articles unless you provide your own. However, if you have multiple shareholders, complex governance needs or specific commercial arrangements, you should consider preparing bespoke articles of association tailored to your requirements.
6. Register with Companies House
You can register your company online through the Companies House website or by post using form IN01. The costs and timelines differ depending on the method you choose.
Online registration costs £100 and the competition is done within 24 hours. Postal registration costs £124 and takes 8 to 10 days.
You will need to provide all the details gathered in the previous steps: your company name, registered office address, director information, share structure and constitutional documents. Once Companies House approves your application, it will issue a certificate of incorporation confirming your company is legally registered.
What You Must Do After Registration
| Register for Corporation Tax | Secure Your Authentication Code | Complete Your Corporate Administration |
|---|---|---|

You need this code to make any future online filings with Companies House. Keep it secure and do not share it. | You should issue share certificates to all shareholders and collect the subscription money for those shares.

You should also set up your statutory registers, which include registers of members, directors, persons with significant control (PSC) and your company’s registered office. |
