Understanding Source of Funds (SOF) vs Source of Wealth (SOW) – The EDD Concept That Fails Most Analysts

             I see this confusion daily in QA reviews. Analysts write SOF when they mean SOW, and vice versa. It's a small mistake that can fail your entire EDD case and your interview.

Let's clear it forever.

1. What is Source of FUNDS (SOF)?

Question it answers: Where did the money for THIS transaction / account come from?

It's about the immediate, specific activity.

SOF is the origin of the funds being used for a particular transaction or to fund an account. It's short-term and transactional.

Examples of SOF:

Salary credited from employerSale of a property (with completion statement)Savings from last 6 months bank statementLoan from a bankGift from family memberBusiness profits / dividendsDocument for SOF:

Bank statement showing the credit, Payslip, Loan agreement, Gift deed + donor's bank statement, Property sale deed.

Example QA Fail: Customer says "My SOF is my business." Wrong. "Business" is not SOF. "£50k dividend from my business XYZ Ltd credited on 15th May from HSBC account ending 1234" – THAT is SOF.

2. What is Source of WEALTH (SOW)?

Question it answers: How did this person get RICH? Where did their TOTAL wealth come from?

It's about the entire financial picture, long-term. How did this person accumulate their net worth over their lifetime / career?

Examples of SOW:

20 years of employment as IT DirectorFamily inheritance over generationsBuilt and sold a business in 2015 for £2MProperty portfolio built over 10 yearsProfessional career as doctor/lawyerDocument for SOW:

CV/LinkedIn showing career history, Companies House showing business ownership, Inheritance documents / Probate, Property portfolio valuation, Annual accounts for 3-5 years.

Standard Risk Retail: Only SOF is enough.High-Risk, EDD, PEP, HNW, Large Transactions: BOTH SOF and SOW are mandatory under JMLSG Part 2 and FCA expectations.If a PEP with £5M net worth wants to deposit £500k, you need:

SOF = £500k dividend from XYZ Ltd (proof: bank statement)

SOW = Accumulated wealth from 15 years as CEO of XYZ Ltd + sale of previous company (proof: Companies House, annual reports, LinkedIn)

If SOW does not make sense with SOF, that's a red flag. Example: Student with no job, SOW = £10k savings, but SOF = £200k property sale. Doesn't add up.

Interview Gold Answer:

Q: "What is the difference between SOF and SOW?"

A: "Source of Funds refers to the origin of the specific funds for a transaction – where the money for this activity came from, like salary, property sale, or business dividend. It's transactional and needed for all customers.

Source of Wealth refers to how a customer accumulated their total net worth over time – their entire financial history, like 20 years of employment, inheritance, or building a business. It's holistic and required for EDD, PEPs, and HNW customers under JMLSG guidance. For high-risk cases, we must verify both and ensure they corroborate."

This one answer shows you think like an EDD analyst, not just a checker.

Common QA Mistakes to Avoid:

Writing "Savings" as SOW – Savings is SOF, not SOW.Writing "Business" as SOF without details – Be specific.Not linking SOF and SOW – Always check if they make sense together.Save this post – interviewers WILL ask this.
