6 Easy Steps to Set Up a Limited Company Online [2026 Guide]

Step : Laying the Groundwork and Naming Your Venture

Before you dive into the digital forms, the most critical step is ensuring your business identity is both legal and available. A limited company is a separate legal entity, which means its name must be distinct from any other business currently registered in the UK.

Choosing a Compliant Company Name

Your name is your brand, but it must also follow strict regulations. It cannot be "too like" an existing name (e.g., if "London Bakery Ltd" exists, you cannot register "The London Bakery Ltd"). Furthermore, you must avoid "sensitive" words that imply a certain status, such as "British," "Royal," or "Chartered," unless you have specific permission. You can learn more about naming restrictions in our detailed guide to company names.

Designating a Registered Office Address

Every UK company must have a physical address where official mail can be delivered. This address is publicly available on the Companies House register. Many home-based entrepreneurs choose to use a professional registered office service to maintain their privacy and ensure they don't have their home address listed on public records.

• Conduct a thorough search using a name availability checker to ensure your brand is unique.
• Ensure your chosen address is in the same part of the UK where your company is registered (England & Wales, Scotland, or Northern Ireland).
• Avoid using trademarked terms that could lead to legal disputes later.
• Consider using a professional service address for directors to protect personal privacy.

Step : Appointing Your Company Officers

A limited company must have people responsible for running it. Even if you are a "one-man band," you will fulfill multiple roles within the legal structure of the business.

Selecting Your Directors

A Director is legally responsible for running the company and ensuring accounts and reports are filed on time. Every company needs at least one director who is a natural person and at least 16 years old. In 2026, directors are required to undergo identity verification as part of the Economic Crime and Corporate Transparency Act, ensuring a higher level of trust in the UK business register.

The Role of the Company Secretary

While no longer a mandatory requirement for private limited companies, many businesses still choose to appoint a Company Secretary. This individual takes on the administrative burden, such as filing the annual confirmation statement and maintaining the statutory registers. If you choose not to have one, these duties fall solely on the directors.

• Directors must provide a service address (public) and a residential address (private).
• Prepare for identity verification by having a valid passport or driving license ready.
• Understand that directors have "fiduciary duties," meaning they must act in the best interest of the company at all times.
• Consult our guide on director duties to understand your legal liabilities.

Step : Structuring Your Share Capital

Ownership of a limited company is divided into shares. This is one of the most important parts of the setup process because it determines who owns the business and who gets a portion of the profits.

Issuing Ordinary Shares

Most small businesses start with "Ordinary" shares. These give the holder voting rights and a right to dividends. You can start with as little as one share valued at £1. This represents the limited liability of the company; if the business fails, the shareholder is only liable for the unpaid value of their shares (usually zero if they were paid for at the start).

Identifying People with Significant Control (PSC)

A People with Significant Control (PSC) is someone who owns more than 25% of the shares or voting rights. You are legally required to identify and register your PSCs. This transparency is a cornerstone of UK corporate law, designed to prevent money laundering and ensure the "true" owners of a business are known.

• Decide on the nominal value of each share (usually £1 per share).
• Allocate shares based on investment or partnership agreements.
• Understand that shares can be issued in different "classes" to vary voting or dividend rights.
• Review our share capital breakdown for complex structures.

Step : Adopting Your Constitutional Documents

Every company needs a set of rules that govern how it is run. These are known as the Memorandum and Articles of Association. Without these, the company cannot be legally incorporated.

The Memorandum of Association

This is a simple legal statement signed by all initial shareholders (subscribers) confirming their intention to form a company and take at least one share each. When you register online via Formation Direct, this document is generated automatically based on the data you provide.

The Articles of Association

These are the "internal rulebook." They dictate how decisions are made, how shares are transferred, and how directors are appointed. Most new companies use "Model Articles," which are standard rules provided by the government. However, if you have multiple shareholders, you might want to customize these to include specific protections or buyout clauses.

• Model Articles are sufficient for most standard startups and single-director companies.
• Bespoke Articles are recommended if you are seeking venture capital or have complex ownership ties.
• These documents become public once the company is registered.
• Explore customizing your articles for better protection.

Step : Assigning SIC Codes and Filing

To help the government track economic trends, you must tell Companies House what your business actually does. This is handled through Standard Industrial Classification (SIC) codes.

Selecting the Right SIC Code

There are hundreds of codes covering everything from "Information technology consultancy activities" to "Retail sale via mail order houses." You can select up to four codes if your business has multiple revenue streams. Choosing the correct code is vital for insurance purposes and for banks when you apply for a business account.

The Final Submission

Once your SIC codes are selected and all director/shareholder details are entered, you perform a final review. In 2026, the online filing fee is paid electronically. Using a professional formation service ensures that your application is "pre-checked" for errors before it reaches Companies House, significantly reducing the risk of rejection.

• Search for the Standard Industrial Classification (SIC) code that most closely matches your primary business activity.
• Ensure all spellings of names and addresses match your official identification documents exactly.
• Double-check that you haven't accidentally assigned 100% of the shares to the wrong person.
• Formation Direct provides a compliance check to catch common mistakes.

Step : Post-Incorporation Compliance

Congratulations, you have your Certificate of Incorporation! But the work doesn't stop there. There are several administrative tasks you must complete to remain compliant with HMRC and UK law.

Registering for Business Taxes

Within three months of starting to trade, you must register for Corporation Tax. You may also need to register for VAT if your taxable turnover exceeds the current threshold (or if you choose to register voluntarily for credibility). Additionally, if you plan to hire employees, you must set up a PAYE (Pay As You Earn) scheme.

Opening a Business Bank Account

Because a limited company is a separate legal entity, you cannot use your personal bank account for business transactions. You must open a dedicated business account. Modern "neo-banks" often offer instant account opening for newly formed companies, often integrated directly with your formation package.

• Keep your Certificate of Incorporation and Share Certificates in a safe, digital place.
• Set up a system for bookkeeping immediately to track expenses and income.
• Mark your Confirmation Statement and Annual Accounts deadlines in your calendar.
• Check out our comprehensive new business checklist.

Action Steps for Success

Follow this checklist to ensure your company formation goes off without a hitch:

• Verify your company name availability before spending money on branding.
• Gather the personal details (DOB, address, occupation) of all directors and shareholders.
• Select a formation package that includes a registered office address to protect your privacy.
• File your application online and wait for the digital confirmation email.
• Apply for your business bank account the moment you receive your company number.
