Source of Funds (SoF)

A mandatory compliance procedure where a UKGC-licensed operator requests documentation to verify the origin of a player's gambling money.

See AML (Anti-Money Laundering) and KYC (Know Your Customer) for full context. A Source of Funds (SoF) request is a standard regulatory check required by the UKGC to combat money laundering and ensure players are gambling within their means. It is not a tactic to withhold winnings.

An operator will initiate an SoF request when a player's deposit activity reaches certain internal thresholds. They will ask for documents to prove the player's source of income, such as payslips, bank statements showing salary, or proof of a house sale or inheritance. Failure to comply will lead to account suspension.
