Section 02 / Supplier completes

Issued form · page 2

Company details and ownership

Identify the legal company once. Reference current public records rather than copying information unnecessarily.

When this applies

Every supplier completes the company record. Additional ownership information is needed only where the referenced record does not explain the actual control.

Help with this section

Open a question for help. The numbers match the printed questions and agreement clauses.

2.1

Legal and trading names

+

What to enter

Use the full registered name of the entity that will supply RCDEN. Add the trading name if different and the legal form. A group brand is not necessarily the contracting company.

Where to find it / what to do next

  1. Search the Companies House register and open the company that will actually contract with RCDEN.
  2. Copy the registered legal name. Put a different brand or trading name in the separate trading-name box.

Useful external help

Opens in a new tab so you can keep this question open.

  • Find your company on Companies House ↗ (opens in a new tab)Companies House

    Search by name or company number. Open the company record for its registered details, filing history and people with significant control.

If you are still unsure

A sole trader may have no Companies House entry. State the actual legal form and name; overseas entities should use their official home-country register.

2.2

Registration number and jurisdiction

+

What to enter

Copy the company or equivalent registration number and the jurisdiction where that entity is incorporated.

Where to find it / what to do next

  1. The company number appears near the top of the Companies House record. Copy the whole number, including any letters or leading zeros.
  2. Use the incorporation certificate or equivalent registry record to confirm the jurisdiction. It is not necessarily the country where you trade.

  • Find your company on Companies House ↗ (opens in a new tab)Companies House

    Search by name or company number. Open the company record for its registered details, filing history and people with significant control.

If you are still unsure

Do not substitute a VAT number, HMRC Unique Taxpayer Reference (UTR) or Government Gateway ID for a company registration number.

2.3

Registered address

+

What to enter

Enter the registered office or lawful service address. Detailed delivery sites are requested only when relevant to particular work.

Where to find it / what to do next

  1. Open the company overview on the register and copy the registered office address.
  2. For an entity without a company register, use its appropriate legal service address. Do not substitute a delivery site just because work happens there.

2.4

Registry and VAT

+

What to enter

Give the current registry or extract reference. Record the VAT number and country, or state not registered or pending. Do not invent an unissued number.

Where to find it / what to do next

  1. For the registry reference, copy the web address of your company's public register entry or reference a current official extract.
  2. For VAT, check your VAT registration confirmation, existing company records or the details held by your accountant. Your HMRC business tax account is the starting point for the company's online tax services.
  3. Use HMRC's VAT checker to check a number you already have. It cannot find a missing VAT number by searching the business name.
  4. The form asks for VAT status and the VAT number if registered. It does not ask for a UTR, tax returns, sign-in details or access codes.

Useful external help

  • Open your HMRC business tax account ↗ (opens in a new tab)HMRC

    The official starting point for business taxes, including VAT, Corporation Tax and PAYE. It explains how to use the account and add a tax service.

  • Open your VAT online account ↗ (opens in a new tab)HMRC

    Access the VAT service for your business. Have the company's existing sign-in details and VAT number ready.

  • Recover access to HMRC online services ↗ (opens in a new tab)HMRC

    Help with forgotten sign-in details, access codes and problems getting into the right account.

  • Check a UK VAT number ↗ (opens in a new tab)HMRC

    Check a number you already have and the business details linked to it. This is not a search for VAT numbers by company name.

If you are still unsure

Enter Not registered only if that is true, or Pending if the registration is still being processed. If you are already registered but cannot find the number, explain that it is being confirmed in 11.1 and continue the other questions.

Link to question 2.4 ↗Your issued form · page 2
2.5

Ownership and control

+

What to enter

Link the current PSC or beneficial-ownership record, or reference your ownership chart. Confirm whether it fully explains ultimate ownership and control.

If it does not, use 11.1 or a referenced continuation to identify the missing owners/controllers, relevant parent entities and chain of control. Record the names, relevant jurisdiction or nationality, and basis or extent of control necessary to explain the chain. Do not provide passports or home addresses.

Check applicability

The UK PSC share/vote starting point is more than 25%, but other control tests also apply. A clear company-name search or a no-PSC entry does not by itself settle sanctions ownership/control.

Where to find it / what to do next

  1. On the company record, open People and the people with significant control (PSC) information.
  2. Check the public record against your current ownership information. If a parent, trust or other arrangement leaves the ultimate control unclear, reference a short ownership chart and explain the missing part in 11.1.
  3. Use the public record or a business ownership summary. Personal identity documents and home addresses are not needed here.

Useful external help

Opens in a new tab so you can keep this question open.

  • Find your company on Companies House ↗ (opens in a new tab)Companies House

    Search by name or company number. Open the company record for its registered details, filing history and people with significant control.

  • Understand people with significant control ↗ (opens in a new tab)Companies House

    Explains ownership, voting rights and other ways a person can control a company, with links to more detailed cases.

  • Check sanctions ownership and control rules ↗ (opens in a new tab)OFSI

    Explains why checking the company name alone may not be enough and how ownership or control can affect restrictions.

If you are still unsure

Your director, company secretary or accountant can help confirm the ownership chain. A no-PSC entry is not a reason to guess that there are no owners or controllers.

Registration contact

+

What to enter

Give the name, role, business email and telephone of the person who can answer registration questions. The same person may also be the security and privacy contact.

Where to find it / what to do next

  1. Choose someone who can answer questions about the company and its evidence. In a small business this may be the director or office manager.
  2. Use a monitored business email and telephone number. The same person can be named for security and privacy if they actually hold those responsibilities.

2.7

Usual supply and countries

+

What to enter

Briefly describe the goods or services you usually supply and your principal operating countries. Exact work packages, sites and overseas access are assessed later if relevant.

Where to find it / what to do next

  1. Use one or two sentences describing the goods or services you expect to supply. Name the principal countries from which you operate.
  2. Describe the real service, for example recruitment introductions or component manufacture. Detailed technical or access arrangements can be addressed if the proposed work needs them.
Link to question 2.7 ↗Your issued form · page 2
Before you move on

Reuse the current public record when it is sufficient. Tell RCDEN about material changes; you do not need to sign a new agreement for a routine evidence renewal.

Have these ready

  • Current company registry details.
  • A current PSC or beneficial-ownership record.
  • One business contact.
