Starting a business in the UK can feel complicated when you are unsure which company structure to choose, what information Companies House requires, or how to complete the registration process. Missing details or misunderstanding the requirements can lead to delays and unnecessary complications, especially if you are registering a company for the first time.

The good news is that the process becomes easier when you understand each step before applying. Choosing a suitable company name, preparing director and shareholder details, arranging a registered office address, and understanding identity verification requirements can help you submit an accurate application. If you need assistance, a company formation service can also help you navigate the process.

This guide explains UK company registration requirements, the steps involved, associated costs, and the responsibilities to manage after incorporation.

  1. Understand What You Are Registering

The first step when you plan to register a company UK is deciding what type of company you want to register. Private limited companies are the most common, as your company will be a separate legal entity from you, limiting your liability to the share capital.

Another reason people prefer private limited companies is that they can be more tax-efficient than being a sole trader, as profits increase. The other types of companies include limited liability partnerships and companies limited by guarantee.

Registration is carried out through Companies House, the official registrar. It can be handled by an Authorised Corporate Service Provider such as Your Company Formations, which submits the filings on your behalf.

  1. Choose a Unique Company Name

Your company name must be unique and not already on the Companies House register, and it must end with Limited or Ltd (Welsh companies may use Cyfyngedig or Cyf).

Certain sensitive words, such as those implying a link to government or a regulated profession, require special permission, and names too similar to an existing trademark can cause problems later. Checking availability before you apply saves time, and a free Companies House name checker is a sensible first step.

  1. Provide a Registered Office and Director Addresses

Each company should have a registered office in the United Kingdom. This address should be a physical address, not a PO box, to which all mail will be sent directly from Companies House and HMRC. The directors should also provide their addresses.

By using your personal address, this information will become public; hence, most individuals opt to use an address service. With Your Company Formations, you can get your registered office and director’s address in Central London, and any statutory post will be scanned and forwarded to your email.

Likewise, your personal address will be provided to Companies House, but this will remain confidential.

  1. Appoint Directors, Shareholders and PSCs

A limited company needs at least one director aged 16 or over and at least one shareholder holding at least one share. One person can fill both roles, which is common among freelancers and consultants. There is no residency requirement and no maximum number of directors or shareholders.

You will need each officer’s full name, date of birth, nationality, occupation, and residential address, as well as the number of shares each shareholder holds. Anyone holding more than 25% of shares must be registered as a Person with Significant Control (PSC). You must also choose a SIC code describing what the business does; dormant companies commonly use 99999.

  1. Complete Identity Verification

Identity verification has become a legal requirement for all people who incorporate and run UK companies. According to the Economic Crime and Corporate Transparency Act of 2023, the mandatory requirement took effect on 18 November 2025, with a 12-month transition period for existing directors and PSCs.

You can verify yourself with the government service Companies House using GOV. UK One Login or through an ACSP with the same level of assurance. The government guidance on identity verification explains who must verify and when.

You will need to upload or take a picture of your passport, driving licence, or any other national ID, and upon verification, you will be given a personal code.

Failing to comply on time is an offence, so treat this as a priority.

  1. Follow the Registration Process

The process itself is straightforward. First, check that your chosen name is available. Second, select a formation package that suits your needs, then provide your company details, including addresses, directors, and shareholder information. Third, the application, together with your articles of association, is submitted to Companies House by you or by your agent.

Fourth, once approved, you receive your certificate of incorporation, which confirms your company number and incorporation date. Through Your Company Formations, the online application takes around 10 minutes, and most companies are incorporated within three to six working hours, subject to Companies House workload.

  1. Budget for Costs and Documents

The Companies House filing cost amounts to £100, while other agent services come on top of that, and the fees for Your Company Formations range from £2.48 plus VAT. The more expensive packages provide printed documentation, confidential addressing, VAT registration and assistance in submitting forms.

Once incorporated, one should expect to receive a certificate of incorporation, memorandum and articles of association, share certificates, and a WebFiling authentication code, which allows one to manage the company with Companies House.

  1. Meet Your Obligations After Registration

Incorporation is the beginning, not the end. Open a business bank account to keep company and personal finances separate, and register for corporation tax with HMRC within three months of starting to trade. If taxable turnover exceeds the VAT threshold, register for VAT, and register for PAYE if you will employ staff.

Each year, you must file a confirmation statement and annual accounts with Companies House, plus a corporation tax return with HMRC. Missing deadlines can lead to penalties and even strike-off. Companies House also publishes quarterly official statistics on identity verification compliance, a reminder that the register is actively monitored.

  1. Registering From Overseas

Being physically present in the UK is not necessary to register a company. Non-residents of the UK or non-British nationals are eligible to register a limited company in the UK on condition that the individual is a director and a registered UK office is appointed.

Identity checks can be done remotely, and various types of business accounts are available for international entrepreneurs, although account approval remains subject to each bank’s criteria.

Specialist non-resident packages bundle a registered office, a director service address, and mail forwarding, which simplifies running a UK company from abroad.

Conclusion

Registering a company in the UK involves choosing the right structure, selecting a compliant name, providing a registered office address, appointing the relevant people, completing identity verification, and submitting the required information to Companies House. After incorporation, you must also manage your tax, reporting, and filing obligations.

Preparing these details in advance can make the process easier to manage and reduce avoidable errors. If you need assistance, compare company formation services and their included features to find an option that meets your registration requirements and budget.
