Thinking about starting your own business in the UK? Whether you’ve dreamed of running your own café, launching the next big tech startup, or freelancing as your own boss, one crucial step to make it official is registering your business with Companies House.
Don’t worry – it’s not as intimidating as it might seem. In this guide, we’ll walk you through the process step-by-step, so you’ll be set up and ready to trade in no time.
Why Registering with Companies House Matters
Registering your business with Companies House gives it legal recognition as a limited company. This means:
-
Your business becomes a separate legal entity from you.
-
You’ll enjoy limited liability, protecting your personal assets from business debts.
-
It boosts credibility with clients, suppliers, and potential investors.
If you’ve decided on a different business structure, such as a sole trader, registration with Companies House isn’t required, but you will need to inform HMRC. However, if you’re forming a limited company, Companies House is your go-to.

Step-by-Step: How to Register Your Business
Step 1: Choose Your Business Name
Your business name is the cornerstone of your brand, so choose wisely! It must be unique and not too similar to existing company names.
Use our FREE Company Name Checker tool to search the database of over 5 million registered company names and more than 11 million registered UK domain names to check if the name you want is available.
The search works by linking directly into the Government's database of company names and checks if the limited company name is available at Companies House.
Pro Tip: Avoid names that could be misleading, offensive or include sensitive words without permission (e.g., “Royal”).

Step 2: Decide on Your Business Structure
Before registration, clarify your business structure. Most people register as a:
-
Private company limited by shares (common for profit-driven businesses).
-
Private company limited by guarantee (ideal for non-profits or community projects).
Not sure which is right for you? A limited by shares structure is the most common for startups and small businesses.
Step 3: Appoint Directors and a Company Secretary
You’ll need at least one director to run the company. Directors are legally responsible for ensuring the company meets its obligations, such as filing annual accounts and returns.
Do you need a secretary? For most small companies, appointing a secretary is optional.
Step 4: Allocate Shares
Decide how the company’s shares will be distributed. This is vital if you have co-founders or investors.
-
Each shareholder must have at least one share.
-
Shares define ownership and influence in the company.
Pro Tip: You can issue different classes of shares if you want to distinguish voting rights or dividends.
Step 5: Prepare Documents for Registration
You’ll need the following:
-
Memorandum of Association: A legal statement signed by all initial shareholders agreeing to form the company.
-
Articles of Association: The rules your company will follow. Companies House provides a standard template, or you can create custom articles.
Step 6: Register Online or by Post
The easiest and fastest way to register is online via the Companies House Web Incorporation Service or using our system that integrates directly with Companies House using their API services.
-
Cost: £50 (online) or £100 (postal).
-
Timeframe: Most online applications are approved within 24 hours. Postal applications can take 8-10 days.
Step 7: Receive Your Certificate of Incorporation
Once your registration is approved, you’ll receive a Certificate of Incorporation. This document confirms your company’s formation and includes its unique company number.
Keep this certificate safe! You’ll need it for opening a business bank account and other official activities.
What’s Next After Registration?
Congratulations – your business is officially registered! Here’s what to do next:
-
Register for Corporation Tax: You must do this within 3 months of trading.
-
Open a Business Bank Account: Essential for separating personal and business finances.
-
Set Up Accounting Processes: Consider hiring an accountant or using accounting software.
-
Promote Your Business: Build your brand, create a website, and connect with your target audience.
