Source of funds checks

Beyond proving who you are, a casino may ask where your money comes from. It is a regulatory duty, and it is separate from sign-up verification.

By Ryan Jessop. Last checked 5 October 2026.

Key takeaways

Triggered by deposit or withdrawal levels and patterns.
Typical evidence: payslips or bank statements.
Accounts can be restricted until you respond.
Every licensed casino must do it.

Short answer: Casinos must check that gambling is affordable and money is legitimate. If asked, send recent payslips or bank statements through the casino's upload tool.

Why it happens

UK operators have duties to prevent money laundering and to identify customers at risk of harm. As deposits rise, or patterns change, they must look more closely.

When you might be asked

Deposits or losses pass internal thresholds.
A large withdrawal is requested.
Spending rises sharply.
Payment methods change frequently.

What is usually accepted

Source	Evidence
Salary	Recent payslips or bank statements showing pay
Savings	Statements showing the balance
Sale of property or assets	Completion statement or sale documents
Inheritance or gift	Letter or documents confirming it

What it means for a new sign-up

Most people who deposit £10 or £20 for a sign-up offer are never asked. The checks become likelier as amounts grow.

If you would rather not

You can decline, but the casino may restrict or close the account. You can still withdraw your balance once identity checks are complete.

What the casino sees

You can usually hide unrelated transactions on a statement as long as your name, the account details and the relevant income remain visible. Check the casino's instructions first; some ask for unedited documents.

Once accepted, the same evidence is not normally requested again unless your activity changes.
