Start Your UK Limited Company

How to Incorporate a UK Limited Company

Starting a UK limited company is straightforward, but getting it right from day one saves headaches later. This guide covers everything from choosing your company name to managing your first year of accounts.

Step 1: Choose Your Company Name

Your company name must be unique and not too similar to existing registered companies. Use the checker above to verify availability. Names ending in "Ltd" or "Limited" indicate a private limited company - the most common type for small businesses in the UK.

Avoid restricted words like "Royal", "Bank", or "University" unless you have the required approvals. These require additional documentation and can delay registration.

Step 2: Prepare Your Documents

To incorporate, you'll need:

• Memorandum of Association - Confirms the subscribers wish to form a company
• Articles of Association - The company's rulebook (most use standard Model Articles)
• Form IN01 - Application to register the company with all required details

Formation agents handle all of this for you, making the process much simpler.

Step 3: Register Your Company

Submit your application to Companies House. Digital applications are processed faster (often same-day) and cost less than paper applications. The standard fee is £50 for digital incorporation.

From November 2025, all directors must verify their identity as part of the incorporation process - either through GOV.UK One Login or via an Authorised Corporate Service Provider (ACSP).

Step 4: Set Up Your Business Essentials

Once incorporated, you'll need:

• Business bank account - Keep personal and business finances separate
• Accounting system - Track income, expenses, and prepare for filing
• Website and email - Professional online presence
• Register for taxes - Corporation Tax (automatic), VAT (if threshold reached), PAYE (if employing)

Important Deadlines for New Companies

Mark these in your calendar:

• Confirmation Statement - Due within 12 months of incorporation, then annually
• First Accounts - Due within 21 months of incorporation (then 9 months after each year end)
• Corporation Tax Return - Due 12 months after your accounting period ends
• Corporation Tax Payment - Due 9 months and 1 day after your accounting period ends
