Source of Funds vs Source of Wealth: A UK PEP Review Guide

A PEP customer says the money comes from savings. The bank statement shows a transfer from another account in their name. You know where the payment arrived from, but do you understand how that money was obtained?

Source of funds explains the money used in a particular relationship or transaction. Source of wealth explains how the person accumulated their wealth. A useful review connects the customer's explanation to evidence, identifies what remains uncertain and records why the proposed relationship is acceptable—or needs further work.

This guide focuses on UK businesses subject to the Money Laundering Regulations 2017 (MLRs), with FCA guidance relevant to FCA-supervised firms. Start with the existing PEP screening guide for identity and status decisions. The task here begins after that assessment: understanding the money.

What changes for a UK PEP review?

Regulation 35(5) requires senior-management approval, adequate measures to establish the source of wealth and funds involved, and enhanced ongoing monitoring for the relevant business relationships. Regulation 35(3) requires a risk assessment; paragraph (3A) sets a lower relative-risk starting point for domestic PEPs and their family members or known close associates, with less extensive measures where no enhanced risk factors exist.¹

Lower relative risk does not remove the assessment. Nor does being a non-domestic PEP automatically make every relationship high risk. FCA FG25/3 describes less intrusive enquiries in lower-risk cases, including using existing records or public information where appropriate. Its approach differs from requiring a fresh bundle of bank statements and tax returns from every customer.²

Other identified risks may call for additional controls under applicable requirements or the firm's own policy. Where the firm goes beyond legal requirements, identify that as company policy and explain why. Additional requests should address the identified risks, rather than follow automatically from the PEP label. Keep PEP status, the customer-risk assessment and the resulting measures separate in the record.

Separate the wealth explanation from the funds being used

Ask two questions and connect the answers:

“From my UK bank account” may answer the payment-route question without answering either of these. Equally, a public salary record may help explain income without explaining a separate large transfer from a company.

Start with what the firm already knows. Identify the gap before requesting more information: a missing receipt, an unexplained payer, a different amount or an unclear ownership interest. Tell the customer what needs explaining in plain language.

Evidence examples: what each record can and cannot show

These are practical options, not a mandatory document list. Select evidence proportionate to the relationship and the question being investigated. Check who issued it, which person or entity it concerns, its date and whether it supports the claimed amount.

A document may be genuine and still answer the wrong question. A company's annual accounts, for example, do not by themselves demonstrate that a shareholder received the amount claimed.

Four fictional cases: follow the explanation through

The cases below illustrate review methods. They are not prescribed outcomes, monitoring frequencies or current salary benchmarks.

A domestic PEP whose savings are consistent with existing records

A UK MP proposes funding a modest investment from an established savings account. The firm already holds a history of salary credits, earlier savings and the customer's explanation of household contributions. No unexplained funding appears in the proposed amount.

The review can assess that information before asking for additional documents. Record which periods and balances support the explanation and why further enquiry is or is not needed. Do not multiply salary by years and call the result savings. Any approval should follow the applicable authority and proportionate process.

A non-domestic PEP receiving business-sale proceeds

A customer attributes a £600,000 investment to selling shares in a private business. The agreement names them as a seller, but only £420,000 appears in the receipt provided.

Ask about that difference. A completion statement might show £180,000 of deferred consideration, making £420,000 the amount received so far. The review still needs to connect the proposed £600,000 funding to available sources. A profitable business or a signed contract does not fill that gap. Seek a relevant explanation and supporting evidence before recording a conclusion.

A company with a PEP beneficial owner and a separate investor

A corporate customer has a confirmed PEP beneficial owner. An unrelated investor supplies the funds for a new project. Separate the questions about the PEP's interest and influence from those about the investor's payment and the company's funding arrangement.

Regulation 35(13) extends the business-relationship provisions to a person of which the individual is a beneficial owner. This does not automatically make the company a PEP, or other shareholders PEPs or known close associates. FCA guidance calls for a case-specific assessment of the PEP's involvement and significant control.¹² Assess the actual ownership, control, funding and risks; do not infer the source of corporate funds from the PEP's personal wealth alone.

A third-party payment that contradicts the explanation

The customer describes a gift from a parent, but the proposed payment comes from an unrelated trading company and the submitted paperwork calls it a loan.

Clarify the payer, relationship, terms and purpose. Record what conflicts and what would resolve it. Refer unresolved concerns through the firm's escalation process, distinguishing a customer-acceptance decision from any separate suspicion and reporting assessment. Neither an incomplete document nor PEP status alone establishes money laundering. Do not approve merely because the file contains a signed agreement.

Write the decision so another analyst can follow it

A useful record explains the assessment rather than just listing attachments:

Approval should come from someone with sufficient knowledge of the firm's money laundering, terrorist financing and proliferation financing risk exposure and sufficient authority to take decisions affecting it.³ FCA FG25/3 permits proportionate approval arrangements; the MLRO need not personally sign every case but retains oversight of the overall process.² Passing a file to a committee does not replace a clear assessment of its unresolved questions.

Use the AML documentation guide for the wider record categories. Regulation 40 ties the usual five-year retention period to the known or reasonably believed end of the relationship, or completion of an occasional transaction, with exceptions and deletion provisions. Do not start one blanket clock when a PEP alert appears.⁴

Reassess when the explanation changes

A new public role, changed ownership, a different funding source or activity inconsistent with the recorded explanation can justify a further review. Set the response according to the legal framework and assessed risk, rather than prescribing quarterly checks for every PEP.

Leaving office also requires care. Regulation 35(9) generally continues the relevant measures for at least 12 months, or longer where appropriate to address risk, subject to paragraph (10). Under paragraph (11), that continuation requirement does not apply to family members or known close associates once the PEP leaves office. They may still require additional controls for other risks, but do not inherit the former officeholder's minimum 12-month period.¹

Ongoing name screening may identify changed political exposure. Reviewing whether payments fit the expected activity is a different control. Keep those responsibilities clear in the broader customer due-diligence process.

Where Checklynx helps

Checklynx PEP screening supports the review of supplied people and companies against configured sources. Clustered results and enriched profiles help analysts compare candidates and assess identity, public roles and relevant relationships.

That provides context for the next questions. It does not verify funds or wealth, authenticate supporting documents, discover every owner, analyse transaction behaviour or make approval and reporting decisions. The compliance team still needs to connect the explanation, evidence and decision.
