8 Simple Steps to Register a Company in the UK in 2026

Registering a company in the UK remains one of the most popular ways for entrepreneurs, freelancers, consultants, eCommerce sellers, and international founders to build a credible business presence. The UK is widely recognised for its transparent company registration system, strong legal framework, global reputation, and access to financial services.

Whether you live in the UK or overseas, you can register a UK limited company online, provided you meet the legal requirements set by Companies House. In 2026, the process is still relatively straightforward, but there are important rules around company names, registered office addresses, directors, shareholders, SIC codes, identity verification, tax registration, and ongoing compliance.

This guide explains the 8 key steps to register a company in the UK in 2026 and what you should do after incorporation to keep your company compliant.

What You Will Learn

By the end of this guide, you will understand:

• How to register a UK limited company
• What information you need before applying
• How to choose a company name
• What a registered office address is
• How directors and shareholders work
• How to choose the right SIC code
• Whether you need a UK business bank account
• What tax and compliance steps come after registration

Step 1: Choose Your Company Name

The first step in registering a UK company is choosing a suitable company name. Your company name is the official legal name of your business and will appear on your certificate of incorporation, Companies House records, invoices, contracts, bank account, and official documents.

Your company name should be clear, professional, and relevant to the type of business you want to operate. A good name can help customers understand what your company does, while also giving your brand a stronger identity.

However, you cannot choose just any name. Companies House has rules on company names. Your company name must not be the same as an existing registered company name or too similar to another company’s name. It must also not contain offensive words or restricted terms unless you have permission.

Some words are classed as “sensitive words” because they may suggest that your company has a special status, qualification, government connection, or regulated authority. Examples include words such as “accredited”, “assurance”, “bank”, “chartered”, or “co-operative”. In some cases, you may need supporting evidence or approval before using certain words.

You should also check whether the name is protected as a trademark. Even if Companies House allows you to register a company name, another business may still have trademark rights over a similar name. This could cause legal problems later.

For most private limited companies, the name must end with “Limited” or “Ltd”. This shows that the company is a limited liability company.

You may also choose to use a trading name. A trading name is the brand name your business uses publicly, which can be different from the registered company name. For example, your registered company could be “ABC Digital Services Ltd”, while your trading name could be “ABC Digital”. If you use a trading name, make sure it does not infringe on another company’s name or trademark.

Step 2: Get a Registered Office Address

Every UK company must have a registered office address. This is the official address where Companies House, HMRC, and other government bodies send letters and legal notices.

Your registered office address will appear on the public Companies House register, so it is important to choose carefully. You can use your own business premises, your home address, your accountant’s address, or a registered office address service.

Many entrepreneurs prefer not to use their home address because it becomes publicly visible. A registered office address service can help protect your privacy and give your business a more professional image.

The address must be a real physical address in the same UK jurisdiction where your company is registered. For example, if your company is registered in England and Wales, the registered office must be in England or Wales. If your company is registered in Scotland, the address must be in Scotland. A PO Box alone is not usually acceptable unless it includes a full physical address.

For non-UK residents, a registered office address service is usually the most practical option because you do not need to rent a physical UK office just to register a company.

Step 3: Appoint Your Company Director

A UK limited company must have at least one director. The director is legally responsible for managing the company and ensuring that the company meets its legal obligations.

A director can be a UK resident or a non-UK resident. This means you do not need to live in the UK to become the director of a UK company.

Companies House will require certain details about each director, including:

• Full name
• Date of birth
• Nationality
• Occupation
• Residential address
• Service address

The residential address is usually kept private, while the service address appears on the public record. Many directors use the company’s registered office or a director service address to avoid showing their home address publicly.

In 2026, identity verification is also an important part of UK company compliance. Companies House has introduced identity verification requirements for directors and people with significant control as part of wider reforms to improve transparency and reduce misuse of UK companies. New and existing directors and PSCs are required to verify their identity under the rollout rules. to UK com

Director Responsibilities

Being a company director is not just a title. Directors have legal duties under the Companies Act 2006.

A director must:

• Act in the best interests of the company
• Follow the company’s constitution
• Make independent decisions
• Exercise reasonable care, skill, and diligence
• Avoid conflicts of interest
• Refuse benefits from third parties that could influence decisions
• Declare personal interests in company transactions

If a director fails to meet these duties, they may face penalties, disqualification, or legal action in serious cases. This is why it is important to understand your responsibilities before becoming a director.

Step 4: Decide Your Shareholder and Share Structure

A private limited company must have at least one shareholder. The shareholder owns the company through shares.

For many small businesses, the director and shareholder are the same person. For example, if you are starting the company alone, you can own 100% of the shares and act as the sole director.

A simple share structure may look like this:

If there are two founders, the structure may look like this:

Shares determine ownership, voting rights, and entitlement to dividends. If your company makes profit and decides to pay dividends, shareholders usually receive dividends based on their percentage of ownership.

For most small companies, ordinary shares are enough. However, some companies use different share classes, such as preference shares or management shares, especially where there are investors, co-founders, or special voting arrangements.

You should think carefully before issuing shares because your share structure affects control, profit distribution, tax planning, investor rights, and future ownership changes.

If you are unsure, speak with an accountant or legal adviser before registering the company.

Step 5: Prepare the Memorandum and Articles of Association

When you register a UK company, you need two constitutional documents: the memorandum of association and the articles of association. This is normally provided by IncorpUK as part of the incorporation package.

The memorandum of association confirms that the first shareholders agree to form the company. If you register online, this is usually created automatically as part of the application process.

The articles of association explain how the company will be run. They set out the rules for directors, shareholders, voting, decision-making, issuing shares, and company administration.

Most new private limited companies use the standard model articles provided by the UK government. These are suitable for many simple companies, especially where there is one founder or a straightforward shareholder structure.

However, some companies need custom articles. This may apply if:

• There are multiple founders
• You want special voting rights
• You have investors
• You want different share classes
• You need specific rules for selling or transferring shares

If you use amended articles, the process may require additional care. In some cases, you may need professional support to make sure the articles are drafted correctly.

Step 6: Choose the Right SIC Code

When registering your company, you must choose at least one SIC code. SIC stands for Standard Industrial Classification. It tells Companies House what type of business activity your company carries out.

Companies House provides a list of SIC codes that businesses can use to describe their nature of business. IncorpUK can select the right SIC codes for your business based on the nature of business you selected on the sign up form.

For example:

You can choose up to four SIC codes if your company has more than one business activity.

It is important to choose a SIC code that accurately reflects what your company does. However, you are not permanently locked into your first choice. If your business activities change later, you can update your SIC code when filing your confirmation statement.

Step 7: Open a UK Business Bank Account

After your company is registered, you should open a business bank account. A separate business account helps you keep company money separate from personal money.

This is important because a limited company is a separate legal entity. Mixing personal and company finances can create accounting confusion and tax issues.

A business bank account helps you:

• Receive customer payments
• Pay suppliers
• Track income and expenses
• Prepare accounts
• Manage cash flow
• Build credibility with customers and partners
• Apply for payment gateways such as Stripe or PayPal

Traditional UK banks may require more checks, especially for non-resident directors. However, fintech providers and digital business banking platforms may offer more flexible options for international founders.

To open a UK business bank account, you may usually need:

• Certificate of incorporation
• Company number
• Registered office address
• Director ID
• Proof of address
• Details about your business activity
• Expected transaction volume

Approval is not automatic. Banks and fintech providers carry out their own compliance checks before opening an account.

Step 8: Register for Tax and Meet Ongoing Compliance Requirements

Registering your company is only the beginning. After incorporation, you must make sure the company stays compliant with HMRC and Companies House.

Corporation Tax

Most UK companies must register for Corporation Tax after they start trading. HMRC usually sends a Unique Taxpayer Reference, known as a UTR, to the company’s registered office after incorporation.

You will use this UTR to manage your company tax account.

Your company may need to file:

• Company Tax Return
• Annual accounts
• Corporation Tax payment
• Confirmation statement

VAT

You do not need to register for VAT immediately unless your taxable turnover goes above the VAT registration threshold. For 2026, the VAT registration threshold remains £90,000, according to current UK government guidance. (GOV.UK)

You must also register if you expect your taxable turnover to exceed the threshold in the next 30 days.

Some companies choose to register for VAT voluntarily, even before reaching the threshold, but this depends on the type of business, customer base, and tax position.

PAYE

If your company pays salaries to directors or employees, you may need to register as an employer and operate PAYE. PAYE is the system used to deduct income tax and National Insurance from salaries.

If you only take dividends and do not pay salaries, PAYE may not be needed immediately. However, you should speak with an accountant before deciding how to pay yourself.

Confirmation Statement

Every UK company must file a confirmation statement at least once every 12 months. This confirms that the company information held by Companies House is accurate and up to date.

The confirmation statement includes details such as:

• Registered office address
• Directors
• Shareholders
• People with significant control
• SIC codes
• Share capital

From 1 February 2026, Companies House lists the digital confirmation statement fee as £50.

How Much Does It Cost to Register a Company in the UK in 2026?

The cost depends on whether you register directly with Companies House or use a company formation provider.

From 1 February 2026, Companies House lists the digital incorporation fee as £100, while paper incorporation is £124.

If you use a formation provider, the price may be higher because packages can include extra services such as:

• Registered office address
• Director service address
• Document preparation
• Business bank account guidance
• VAT registration support
• Confirmation statement support
• Compliance reminders

For non-residents, using a formation provider can be helpful because the process often involves more than just registering the company.

How Long Does It Take to Register a UK Company?

Many UK company formations are completed within 24 to 48 hours when the application is straightforward and all information is correct.

However, it can take longer if:

• The company name needs review
• Sensitive words are used
• ID verification is delayed
• Details are incorrect
• Additional checks are required
• The application is submitted by post

To avoid delays, make sure your information is accurate before submission.

Can Non-Residents Register a UK Company?

Yes. Non-UK residents can register and own a UK limited company. You do not need to live in the UK, be a UK citizen, or have a UK visa to form a UK company.

This is one reason UK company formation is popular among international entrepreneurs. A UK company can help global founders build credibility, access international business tools, apply for payment gateways, and work with customers worldwide.

However, non-resident founders still need to comply with UK company law, tax obligations, identity verification requirements, and banking checks.

Common Mistakes to Avoid When Registering a UK Company

Many new founders make avoidable mistakes during company registration.

The most common mistakes include:

• Choosing a name that is too similar to another company
• Using a home address without understanding it will appear publicly
• Choosing the wrong SIC code
• Issuing shares without thinking about future ownership
• Forgetting to file the confirmation statement
• Missing Corporation Tax registration
• Ignoring VAT once turnover grows
• Mixing personal and company finances
• Not keeping proper records
• Assuming a UK company means no tax obligations

A UK company is simple to register, but it must still be managed properly.
