Forming a company in the United Kingdom (UK) provides numerous commercial perks, including opening you up to millions of potential high-value clients in the UK and the European Union (EU).

Since the company formation process typically culminates in full registration, it also confers your business’s legal identity. You can officially apply for financing, compete in government tenders, and unlock critical tax advantages.

Forming a company in the UK enhances your brand’s credibility, too. This is especially important for foreigners who establish in the UK. In this age of rampant corporate fraud, clients are growing increasingly wary of engaging with unregistered businesses.

Now, the company formation process can be long and tedious or quick and hassle-free. It all depends on adequate preparation. One way to escalate the process is by gathering essential documents.

In this post, we examine the eight critical documents to have when applying for company formation and banking in the United Kingdom.

1. Proof of ID

Proof of identity (ID) is mandatory in nearly all official administrative processes, including business registration. To proceed with company formation UK with bank account, the government must validate that you’re who you say you are.

In the United Kingdom, you can prove your identity by producing at least one of the following documents;

  • Passport – UK-issued or international (for foreign nationals)
  • Photo driving license – UK-issued or EU-issued
  • EU national identity card
  • Proof of Age Standards Scheme (PASS) cards, such as CitizenCard

Besides authenticating your identity, proof of ID also verifies your age. It ensures you’ve attained the legal age of majority to own a company.

In certain cases, proof of ID enables government agencies to conduct a background check on your criminal history.

Known terrorist sympathizers, anyone previously implicated in money laundering, and those with questionable income may be barred from setting up a place of business in the country.

2. Proof of Residential Address

UK residents must provide proof of their residential addresses. It’s how the government and financial institutions validate that you truly reside in the country.

Examples of documents that may prove your residential address include;

  • Utility bills like electricity, water, gas, or landline telephone
  • Council tax bill
  • Financial statements from existing bank accounts, lenders, endowment schemes, pension schemes, etc.
  • Credit card statements
  • Building society statements

Typically, the proof of address must be dated within three months.

3. Address List

Every company requires a UK-registered office address to conduct business legally in the UK.

A registered office address constitutes your company’s official legal address, typically handling government correspondence.  It differs from a service address used for correspondence with individuals with a legal role in the company (directors, secretaries, etc.).

A registered office address can be an address used by your other businesses, your home address, or even a virtual address. Just ensure it’s not a Post Office (P.O.) Box address.

Besides a registered office address and service address, you may also require a billing address. This is the address where all your company’s bills are sent.

4. MoA

The memorandum of association (MoA) is an essential legal document required to go ahead with company formation in the UK.

The MoA primarily outlines your business’s relationship with shareholders and other external entities.

It also defines the company’s mission and vision.

The MoA is created by Companies House during the business registration process. It must be signed by all the company’s initial shareholders or guarantors, known as subscribers.

5. AoA

The articles of association (AoA) go hand in hand with the memorandum of association.

However, like the MoA, which defines the scope of a business’s engagement with external stakeholders, the AoA outlines the rules governing the company’s internal management structure.

Essential components of an article of association include director shares, managerial roles, and the organization’s hierarchical structures.

Companies House provides model articles of association, which you can amend to suit your company’s requirements.

6. Directors and/or Guarantors List

Directors are employees charged with a company’s overall governance. They’re members of a board, which constitutes the second-highest decision-making organ after the shareholders.

Meanwhile, guarantors provide personal obligations to offset a company’s loans in the event of default.

When applying for company formation in the UK, you’ll typically be required to submit at least three of the following shareholder or guarantor information;

  • Passport number
  • National insurance number
  • Birth town
  • Telephone number
  • Mother’s maiden name
  • Father’s first name

7. Shareholders’ List

All limited companies (whether public or private) must have shareholders. To get registered, you’ll need to supply important shareholder details to Companies House. That includes;

  • Names (as captured in their proof of ID documents)
  • Addresses (as highlighted in their proof of address documents)
  • Contact information, including telephone and mobile numbers
  • Share quantity and class, which allocates appropriate voting rights

While not mandatory at the initial company formation stage, you may consider availing a share certificate, too. This document highlights shareholders’ ownership stakes in your company more elaborately. Essential details include;

  • Company’s name
  • Certificate number
  • Shareholders name
  • Shareholders’ address and contact information
  • Number of shares owned by each individual
  • Share class
  • Amount (actually or intrinsically) paid on the shares owned

In most circumstances, share certificates are generated after a company goes into full operation. However, it’s important to keep this document in mind while applying for company formation in the UK.

8. PSCs List

Persons with Significant Control (PSCs) are individuals or legal entities that command a substantial stake in your company. Examples include shareholders that hold;

  • Over 25% of the shares in the business
  • Over 25% of voting rights
  • The right to veto certain board of director decisions

Provide detailed information on your PSCs separately, even if you’ve already captured it in the shareholders’ list. Indicate their names, contacts, addresses, designations, and the specific powers they wield in the company.

NOTE: High-ranking managers don’t necessarily constitute PSCs unless they fall in any of the above categories. However, some company directors may double up as PSCs if they happen to own significant shares or privileges in the organization.
