What is Source of Funds?
Documentation required by casinos to prove that the money being used for gambling has been legitimately earned. Part of AML compliance. Typically requested when cumulative deposits or losses exceed certain thresholds.
In Depth: Source of Funds
Source of funds checks are increasingly common at UK casinos following UKGC pressure to improve AML controls. They are not personal — they are a legal requirement triggered by deposit or loss thresholds.
Acceptable evidence includes:
- Payslips (most common)
- Bank statements showing salary credits
- P60 or P45 (employment income)
- Tax return (self-employed)
- Pension statements
- Investment or dividend statements
- Proof of inheritance with supporting documentation
How to approach them: Respond promptly with clear documents. The casino must process your pending withdrawal during the verification. Unreasonable delays beyond 5 business days should be escalated.

Pending Period
A window of time (typically 24–48 hours) after requesting a withdrawal during which the transaction is held and can be reversed. Allows casinos to conduct fraud checks, but can also be used to entice players to gamble back their winnings.
KYC (Know Your Customer)
Mandatory identity verification required by UKGC-licensed casinos before processing withdrawals. Players must prove their identity, address, and sometimes source of funds to comply with UK anti-money-laundering regulations.
