Starting a business in the UK? Setting up a limited company is one of the best ways to protect yourself legally and give your business a professional edge. Whether you’re launching your first startup or formalizing a side hustle, this guide will walk you through the process—step by step.
If you’re already working on your business plan template, pitch deck template, or startup financial model, this is the next big milestone in making your business official. Let’s dive in!
1. Choose a Company Name
Your company name needs to be unique and comply with Companies House rules. Before you settle on a name:
✅ Use the Companies House name availability checker to see if it’s free.
✅ Check the UK Intellectual Property Office (UKIPO) trademark search to avoid legal issues.
✅ Secure a domain name using Hostinger so you can build your website.
2. Register Your Business Address
Every UK limited company needs a registered office address—this is where official correspondence from HMRC and Companies House will be sent. It must be a physical address in the UK, but if you don’t have a business premises yet, you can use a virtual office service.
3. Appoint Directors and a Company Secretary
A limited company must have at least one director who is legally responsible for the company’s operations. A company secretary is optional, but some businesses appoint one to handle admin tasks.
4. Decide on Shareholders and Shares
If your business has multiple owners, you’ll need to allocate shares. Even if you’re the sole founder, you’ll still be the 100% shareholder. If you’re planning to raise investment, setting up a startup cap table template will help you track ownership from day one.
5. Create and Submit Your Company Documents
To register your company, you’ll need:
📄 Memorandum of Association – A legal document confirming the company formation.
📄 Articles of Association – Rules for running your company, signed by shareholders.
Companies House provides standard templates, or you can create your own.
6. Register with Companies House
Once you’ve got everything in place, it’s time to register your company. You can do this online via the CompaniesHouse website for £12, and it’s usually approved within 24 hours.
7. Register for Corporation Tax and VAT
After setting up your company, you must register with HMRC for Corporation Tax within three months. If your turnover is expected to exceed £90,000, you’ll also need to register for VAT.
8. Set Up a Business Bank Account
A separate business bank account makes accounting and tax filing easier. Many startups choose Revolut for Businessfor its low fees, multi-currency options, and easy online management.
9. Organize Your Financials
Having a solid financial plan from the start will save you stress later. Consider using a startup financial modeltemplate to project your income, expenses, and funding needs. If you’re raising investment, a pitch deck template will help showcase your numbers.
10. Keep Up with Compliance and Filing Requirements
Once your company is registered, you’ll need to file:
📌 Annual Confirmation Statement (to update company details).
📌 Annual Accounts (financial records for HMRC and Companies House).
📌 Corporation Tax Return (to pay any tax owed).
Using an accountant or small business accounting software can help keep things in check.
