United Kingdom corporate onboarding: documents, risks and rules

Companies House gives an onboarding team a useful starting point: officers, control disclosures and corporate filings are available together. The important work is interpreting them. A person with significant control is not necessarily the account signatory, and the latest confirmation statement does not necessarily repeat a complete shareholder list. The file needs to connect those records to the customer's current ownership and proposed activity.
Which rules apply
For UK firms within scope, the Money Laundering Regulations 2017 require customer identification and verification, beneficial ownership checks, an understanding of the relationship and ongoing monitoring. Companies House disclosure duties, including the people with significant control (PSC) framework, serve a separate purpose. The firm's beneficial ownership assessment should apply its own regulatory criteria rather than simply copy the names displayed as PSCs.
The duties follow the onboarding firm's location, regulatory status and service. An overseas firm applies its own relevant regime to this customer. Ordinary commercial counterparties can also use these records for risk assessment without having the same duties as regulated firms.
Documents commonly requested
The starting file should reflect the legal form and the proposed relationship. These records answer complementary questions:
| Evidence | What the reviewer looks for |
|---|---|
| Company overview and incorporation record | Company number, legal form, status and continuity after name changes |
| Current officers and appointment filings | Who holds office and whether later resignations affect the applicant |
| PSC information and relevant filings | The recorded nature of control and any ceased or incomplete disclosures |
| Confirmation statements and current register of members | Dated shareholder evidence reconciled with subsequent changes |
| Articles, resolution or mandate | Share rights and authority for the proposed account or transaction |
| Identity and business evidence | Relevant individuals, expected payments and funding |
Registry records establish facts within their stated scope. Current ownership records, identity evidence and mandates may need to come from the client or another permitted source. Keeping those origins visible helps explain differences and the extent of independent corroboration.
The risks behind the paperwork
A PSC disclosure is not a shareholder register. A PSC can qualify through shares, voting rights, board appointment rights or other influence. Conversely, smaller registered shareholders may not appear as PSCs. A corporate entity in the disclosure needs further investigation where required to understand ultimate control. Comparing the PSC position with the current register of members makes those distinctions visible and helps explain why the firm has identified particular beneficial owners.
An annual confirmation can leave an ownership gap. Relevant incorporation documents, earlier returns and subsequent changes may be needed to reconstruct holdings. A recent filing date alone does not show that every shareholder detail was repeated. Where a client reports a transfer after the latest relevant filing, current member records and transfer evidence help explain it. Unresolved differences should remain questions in the assessment rather than disappear into a copied registry profile.
Registered activity can differ from actual trading. An active status and a business activity code establish registered information, not profitability, liquidity or regulatory permission. Dormant or reduced accounts may fit the company's filing category while saying little about today's trading. If the client proposes substantial payments, contracts and current financial information should explain the business behind them. Registered charges can also matter to a credit assessment, but their stated amounts need interpretation.
Where the customer advertises a regulated service, compare the licence holder with the company number in the agreement. A parent company's permission does not automatically cover its subsidiary. Likewise, the person emailing an instruction needs the relevant authority even if their name appears as a director or owner.
How the Fill Easy email bot helps
An approved organisational sender can request available registry documents from agent@fill-easy.com, using prose, a table or an attached spreadsheet. Include the company identifier and required documents:
Please retrieve current company particulars, officer and PSC records, relevant confirmation statements and accounts for [company name], company number [number]. Reference: [case reference]. Please include a summary report and confirm availability, price and expected turnaround.
The agent replies with item statuses, asks for clarification where needed, and returns retrieved PDFs in the same thread. Results carry their source, retrieval time and request ID. An optional summary references the documents. Availability, price and expected turnaround are confirmed at acceptance.
This helps the team collect and reconcile the registry evidence. Client-held records and individual identity evidence still follow the appropriate process, while the reviewer resolves remaining gaps and makes the onboarding decision. See the Mailbox workflow for the email process.
