Setting up limited company is one of the most popular ways to start a business in the UK. A private limited company (Ltd) gives business owners a separate legal identity, limited liability protection, and a more professional structure when dealing with clients, suppliers, and investors.
The process of setting up a limited company in the UK is relatively straightforward. You can register online with Companies House, usually within 24 hours, provided you have the correct information ready.
This guide explains how to set up a limited company, the requirements involved, the costs, tax responsibilities, and what you need to do after incorporation.
What Is a Limited Company?
A limited company is a business structure that is legally separate from the people who own and run it.
When you set up a limited company, the business becomes its own legal entity. This means the company is responsible for its debts and obligations rather than the shareholders personally.
Key features of a limited company include:
- Limited liability: Directors and shareholders are generally not personally responsible for company debts.
- Separate finances: Company money must be kept separate from personal finances.
- Professional structure: A limited company can improve credibility with customers, suppliers, and lenders.
- Tax responsibilities: The company must follow UK rules for Corporation Tax, payroll, VAT, and annual filings.
Limited companies are commonly used by:
- Contractors
- Consultants
- Freelancers
- Start-ups
- Small business owners
- Growing companies
Why Set Up a Limited Company?
Many people choose to set up a limited company because it offers advantages that may not be available through other business structures, such as operating as a sole trader.
Benefits of Setting Up a Limited Company
Limited Liability Protection
A limited company protects shareholders by separating personal assets from business liabilities. If the company experiences financial difficulties, personal assets are usually protected.
Potential Tax Efficiency
A limited company pays Corporation Tax on its profits. Depending on your income level and circumstances, extracting profits through a combination of salary and dividends may be more tax-efficient than paying Income Tax as a sole trader.
Increased Business Credibility
Some clients, especially larger organisations, prefer working with registered companies because it provides a more established business image.
Flexible Profit Extraction
Company owners can usually take money from the business through:
- Director’s salary
- Dividends
- Pension contributions
- Other approved business expenses
Who Can Set Up a Limited Company in the UK?
Almost anyone can set up a limited company in the UK, provided they meet the legal requirements.
You must have:
- At least one director
- At least one shareholder
- A registered office address in the UK
- Information about company ownership and control
A director must usually be aged 16 or over.
You do not need to be a UK resident to create a UK limited company, but you must understand your UK tax and reporting obligations if the company operates in Britain.
How to Set Up a Limited Company Step by Step
1. Choose a Company Name
The first step when setting up a Ltd company is choosing a suitable name.
Your company name must:
- Be unique and not too similar to an existing company
- Not include restricted or sensitive words without permission
- Not mislead customers
- Usually end with “Limited” or “Ltd”
Before registering, you should check:
- Companies House name availability
- Trademark conflicts
- Domain name availability
A suitable company name helps build a strong business identity from the start.
2. Decide Your Directors and Shareholders
Every limited company needs at least one director.
Directors
A company director is legally responsible for managing the company and ensuring it meets its obligations.
Directors must:
- Act in the company’s best interests
- Maintain accurate records
- Submit required filings
- Ensure taxes are paid correctly
Shareholders
Shareholders own the company and receive profits through dividends.
A person can be:
- The only director and shareholder
- One of several directors
- One of several shareholders
When registering, you must provide details of shareholders and the number and value of shares issued.
3. Choose a Registered Office Address
A registered office address is the official address of your company.
It must:
- Be a physical UK address
- Be available for official correspondence
- Appear on the public Companies House register
This address is where government letters and legal documents will be sent.
Many small businesses use their accountant’s address as a registered office service to keep their home address private.
4. Choose a SIC Code for Your Business Activity
A SIC code (Standard Industrial Classification code) tells Companies House what your company does.
You must select the correct SIC code when registering your limited company.
Examples include:
- Construction activities
- IT consultancy
- Retail businesses
- Professional services
Choosing the correct SIC code ensures your company information accurately reflects your business activities.
5. Prepare Company Formation Documents
To create a limited company, you will need important legal documents.
These include:
Memorandum of Association
This confirms that the initial shareholders agree to form the company.
Articles of Association
These explain how the company will be managed, including rules around:
- Directors
- Shareholders
- Decision-making
You will also provide:
- Director details
- Shareholder information
- Statement of capital
- People with Significant Control (PSC) details
6. Register Your Company with Companies House
You can register a limited company through:
- Online registration
- Postal application
- A company formation agent
- An accountant
Online registration is the quickest option for most businesses.
Once approved, you will receive:
- Certificate of Incorporation
- Company registration number
- Official company status
The registration fee depends on the method used. The Companies House online incorporation fee is currently £50.
How Much Does It Cost to Set Up a Limited Company?

What Happens After Setting Up a Limited Company?
Registering your company is only the beginning. A limited company has ongoing responsibilities.

After incorporation, your company must deal with HM Revenue & Customs.
You normally need to register for Corporation Tax when your company starts trading.
Corporation Tax applies to:
- Trading profits
- Investment income

The amount of Corporation Tax depends on company profits and the applicable tax rates.
Open a Business Bank Account

Keeping personal and company finances separate helps with:
- Accurate accounting records

- Business management
Banks usually request:
- Certificate of Incorporation
- Company number
- Director information
Understand Limited Company Tax Responsibilities
Director’s Salary
A director’s salary is usually processed through PAYE and may involve:
- Income Tax
- National Insurance contributions
Dividends
Dividends are payments made to shareholders from company profits after Corporation Tax has been paid.
They are taxed differently from salary payments.
VAT Registration
A limited company must register for VAT if taxable turnover exceeds the VAT registration threshold.
Businesses may also voluntarily register for VAT if it benefits their operations.
Limited Company Accounting and Record Keeping
A limited company must maintain accurate financial records.
You should keep records of:
- Sales invoices
- Purchase invoices
- Bank statements
- Payroll information
- Expense receipts
- VAT records
Most business records must be kept for at least six years.
Good record keeping makes annual accounts, tax returns, and compliance much easier.
Annual Filing Requirements for a Limited Company
Every limited company has ongoing filing obligations.
Annual Accounts
Company accounts must be submitted to Companies House.
Corporation Tax Return (CT600)
A Corporation Tax return must be submitted to HMRC after the accounting period ends.
Confirmation Statement
A confirmation statement updates Companies House about company details, including:
- Directors
- Shareholders
- Registered office information
Missing deadlines can result in:
- Financial penalties
- Company strike-off
- Director issues
Common Mistakes When Setting Up a Limited Company
Many new company owners make avoidable mistakes, including:
- Choosing the wrong business structure
- Using an incorrect SIC code
- Missing Corporation Tax registration deadlines

- Paying dividends incorrectly
- Failing to maintain records
Getting professional advice early can prevent expensive problems later.
