How to Register a Limited Company in the UK – Step-by-Step Guide

Starting a business is exciting—but it also comes with important decisions. One of the first is choosing the right legal structure. If you’ve decided to form a limited company in the UK, this step-by-step guide from TT Accountancy in London will walk you through the entire registration process.


Why Choose a Limited Company?

A limited company is a popular business structure in the UK because it offers:

  • Limited liability protection
  • Greater tax efficiency
  • Professional status and credibility
  • Separate legal identity from its owners

Step 1: Choose a Company Name

Your company name must be:

  • Unique – It must not be identical or too similar to existing names on Companies House.
  • Compliant – Avoid sensitive or restricted words unless you have permission.
  • Professional – This reflects your brand, so choose wisely.

Use the Companies House name availability checker to confirm your chosen name.


Step 2: Decide on a Company Structure

Most businesses register as a Private Company Limited by Shares (Ltd). This structure includes:

  • Shareholders – Own the company
  • Directors – Manage the company
  • Shares – Determine ownership percentage

You’ll need at least one director and one shareholder (the same person can fulfill both roles).


Step 3: Prepare Key Company Documents

You’ll need to draft two essential documents:

  • Memorandum of Association – Legal statement signed by initial shareholders
  • Articles of Association – Rules on running the company

You can use the default model articles or create custom ones with help from TT Accountancy.


Step 4: Register with Companies House

You can register your company:

  • Online via Companies House – Fast and costs £12
  • By post – Slower and costs £40
  • Through an accountant – Ideal if you want expert help (recommended for first-time directors)

TT Accountancy can handle the full company formation process on your behalf.


Step 5: Register for Corporation Tax

Once your company is registered, you must:

  • Register for Corporation Tax within 3 months of starting business
  • Provide your company’s UTR (Unique Taxpayer Reference), issued by HMRC
  • File your annual accounts and company tax return

We at TT Accountancy in London offer full support with ongoing compliance and HMRC registrations.


Step 6: Open a Business Bank Account

As a limited company is a separate legal entity, it must have its own business bank account. Most UK banks require:

  • Certificate of incorporation
  • Proof of ID and address for directors
  • Company’s Articles of Association

We can advise you on the best business banking options for startups.


Step 7: Maintain Statutory Records and File Annual Returns

Once set up, your responsibilities include:

  • Filing Confirmation Statements
  • Submitting Annual Accounts
  • Keeping a PSC register (People with Significant Control)
  • Maintaining accurate financial records

TT Accountancy offers affordable compliance packages to help your company stay on track.
