Start with the register

Start with the free Companies House search. It can show a company’s registered address, incorporation date, officers, filings, and insolvency information. Registration is a starting point for checking a business; it does not establish that the person contacting you represents it or that a proposed transaction is safe.

Sole traders and ordinary partnerships do not have the same Companies House record as limited companies. Check the legal form before treating an absent company record as a warning; limited liability partnerships do appear on the register.

Checks for specific kinds of business

Checking the person

Where you are dealing with an individual, or with the person behind a small company, look at whether the person as presented actually exists.

Checking the property, vehicle, or goods

The warning signs that should stop a payment

These are reasons to pause and verify independently, especially in combination. None proves fraud on its own; legitimate small businesses can have a limited online presence or use a mobile number.

If you have already paid, contact your bank promptly using a number you trust. Ask what recovery or reimbursement options apply to your payment; a recovery is not guaranteed. The reporting routes below are separate from notifying your bank.

When to instruct due diligence

The checks above are a starting point for routine transactions, not a guarantee. A formal due diligence report may be useful where the financial or reputational exposure justifies deeper verification: a business acquisition, significant supplier contract, investment, or overseas counterparty.

An agreed report can examine control and ownership, available litigation and insolvency records, adverse media, relevant sanctions exposure, and the evidence for claimed assets or trading history. Coverage and access vary by jurisdiction. Reports should identify gaps rather than imply that every asset or connection can be established. Our corporate due diligence page explains the scope and fee approach.

For an individual rather than a company, such as a new business partner, a prospective tenant of a high-value property, or someone about to be given access to family money, the same work is done on the person, within the limits of the data protection legislation and with a lawful basis recorded for it.

If you have already been defrauded

Contact your bank first. In England, Wales, and Northern Ireland, report fraud through Report Fraud, the service that replaced Action Fraud. In Scotland, contact Police Scotland on 101. Preserve the emails, invoices, payment details, and any record you already have of the website. Where the sum justifies it, an investigation may help identify who was involved or locate relevant assets; a solicitor can advise on recovery and any urgent court application. Our workplace and fraud investigation page covers that work; the first conversation is free and we will say whether recovery is realistic.

We will not tell you whether to proceed with a transaction. A report sets out what was found and what could not be verified, and the decision stays with you. What we will do is say plainly when something does not add up.
