A source of funds check is a process a bookmaker may use to understand where the money being used for gambling comes from. Depending on the circumstances, a betting operator may ask a customer for information or documents relating to their finances.
This is different from a standard identity check.
Identity verification is primarily concerned with establishing information such as who you are, your age and potentially your address. A source of funds check concerns the origin of money associated with your gambling.
Not every betting customer will receive the same requests, and the information required can depend on the circumstances.
If a bookmaker asks you for financial information, it should explain what it requires and how you can provide it securely.
This guide explains source of funds checks, why bookmakers carry them out, what information might be requested and what you can do if you receive a request.
What Is a Source of Funds Check?
A source of funds check seeks information about where particular money comes from.
For example, funds could potentially originate from:
- employment income
- self-employment
- savings
- investments
- pension income
- property transactions
- inheritance
- other legitimate sources
The important distinction is that the bookmaker is not simply asking:
Who are you?
It may be asking:
Where have the funds associated with this gambling activity come from?
The exact nature of a check depends on the circumstances and the operator’s requirements.
Why Do Bookmakers Carry Out Source of Funds Checks?
Licensed gambling operators have responsibilities relating to areas including anti-money laundering, customer protection and safer gambling.
Financial information can form part of the processes operators use to meet relevant obligations.
A bookmaker might need to understand financial activity where particular circumstances require further consideration.
This does not mean every customer will automatically be asked to provide bank statements or prove their income.
Different customers can experience different checks.
Is Source of Funds the Same as ID Verification?
No.
The two processes can overlap because both may involve supplying documents, but they have different purposes.
| Check | Main Purpose |
|---|---|
| Identity verification | Establish who you are |
| Age verification | Establish that you are old enough to gamble |
| Address verification | Confirm residential information |
| Payment verification | Check information relating to a payment method |
| Source of funds | Understand where relevant money comes from |
If you have been asked for ordinary identification rather than financial information, read Betting Account Verification Explained and Why Do Bookmakers Ask for ID?
What Is the Difference Between Source of Funds and Source of Wealth?
These terms are related but should not automatically be treated as interchangeable.
Source of funds generally concerns the origin of particular money being used or involved in transactions.
Source of wealth is a broader concept concerning how someone accumulated their overall wealth.
For example, somebody might have accumulated wealth through owning and later selling a business, while the immediate source of funds used for particular activity might be money held in a bank account.
If a bookmaker uses either term, ask what information it specifically requires rather than assuming the two requests mean exactly the same thing.
Do All Bookmakers Carry Out Source of Funds Checks?
UK-licensed gambling businesses operate under regulatory requirements, but this does not mean every customer receives an identical financial-information request.
The checks carried out can depend on the customer, activity and circumstances.
You should therefore avoid assuming that because a friend has never been asked for financial information, you cannot be asked.
Equally, receiving a request does not mean everyone using that bookmaker has received one.
When Might a Bookmaker Ask About Your Funds?
There is no single point at which every customer receives a source of funds request.
Financial or account checks can arise during the customer relationship.
A request might occur after an account has been open for some time rather than during initial registration.
This is one reason it is useful to distinguish between:
opening an account
and
ongoing account checks.
Our How to Sign Up to a Betting Site guide explains the initial registration process.
Does a Source of Funds Check Mean You’ve Done Something Wrong?
Not necessarily.
Receiving a request for information does not by itself establish that the bookmaker believes you have committed wrongdoing.
Operators conduct checks for regulatory, financial-crime, account-management and customer-protection reasons.
The appropriate response is to establish exactly what information has been requested and why.
If the request is unclear, contact the bookmaker through its official customer-service channels.
What Can a Bookmaker Ask For?
The information requested depends on the circumstances.
Potential examples of documents or evidence can include:
- bank statements
- payslips
- tax-related documentation
- evidence of savings
- information relating to investments
- evidence relating to a property transaction
- pension information
- evidence concerning an inheritance
- other financial documentation relevant to the stated source
This is not a universal checklist.
Do not send every financial document you possess simply because a bookmaker has asked about your funds.
Read the request and provide what is legitimately required through the appropriate process.
Why Do Bookmakers Ask for Bank Statements?
A bank statement can provide information relevant to several types of account check.
Depending on the circumstances, it could potentially be used in connection with:
- address verification
- payment verification
- financial activity
- source of funds
- other account checks
Therefore, receiving a request for a bank statement does not automatically tell you the purpose.
The bookmaker should explain why it needs the document.
What Can a Bookmaker See on a Bank Statement?
A bank statement can contain significant amounts of personal financial information.
Depending on the statement, this can include:
- your name
- account information
- transactions
- income
- payments
- balances
- transfers
This is why financial documents should be treated as sensitive.
If you are asked for one, check exactly:
- which statement period is required
- which pages are required
- what information needs to be visible
- whether anything may legitimately be redacted
- how the document should be uploaded
Do not independently alter a document without checking the bookmaker’s requirements.
Can You Redact a Bank Statement?
Do not assume that you can or cannot redact information.
The bookmaker may need particular information to complete the check.
If you are uncomfortable supplying unrelated information, ask the operator which details must remain visible and whether other information can be obscured.
Follow its instructions.
Submitting an incorrectly redacted document may simply result in another request.
Why Might a Bookmaker Ask for Payslips?
Payslips can provide evidence relating to employment income.
If a customer states that their gambling funds come from salary, a bookmaker carrying out a relevant check might request evidence supporting that information.
That does not mean payslips are routinely required from everyone opening a betting account.
They are different from the basic information commonly provided during registration.
What If You Are Self-Employed?
Not everyone receives income through conventional monthly payslips.
If you are self-employed and a bookmaker requests evidence relating to income or funds, ask which documents it accepts for your circumstances.
The relevant evidence could differ from that requested from an employed customer.
Do not submit unrelated documents simply because you do not have a payslip.
Ask the operator what it needs.
What If Your Money Comes From Savings?
Savings can be a legitimate source of funds.
If a bookmaker needs evidence concerning savings, it should explain what documentation is required.
The purpose of the check is not changed simply because the money does not come directly from a monthly salary.
The relevant question is where the funds originated and what evidence the operator needs.
What If Your Money Comes From Investments?
Investment proceeds can potentially form a source of funds.
If this is relevant to a check, the bookmaker may request information supporting the origin of those funds.
The documentation required will depend on the circumstances.
Follow the specific request rather than sending general screenshots of investment accounts without understanding what is needed.
What If the Money Came From Selling a Property?
Money generated from a property transaction could potentially be relevant when explaining the origin of funds.
A bookmaker conducting a check should tell you what evidence it requires.
This could be different from evidence requested from somebody whose funds come from employment.
What If the Money Came From an Inheritance?
An inheritance can also represent a source of funds.
Again, the appropriate evidence depends on the circumstances.
If a bookmaker asks about inherited money, ask which documentation it accepts and what exactly needs to be demonstrated.
Can Gambling Winnings Be a Source of Funds?
Previous gambling winnings can potentially form part of someone’s available funds.
However, if you state that money came from previous gambling activity, a bookmaker may require information that supports this.
Do not assume that simply stating “winnings” will necessarily complete a check.
Provide accurate information and follow any legitimate request for supporting evidence.
Do Bookmakers Check Your Income?
Bookmakers can carry out financial checks in certain circumstances.
This should not be confused with every new customer routinely submitting their salary before being allowed to open an account.
The level and nature of financial checks can vary.
If you receive a request, concentrate on what the bookmaker is actually asking you rather than what another bettor experienced.
What Are Financial Risk Checks?
The UK gambling regulatory framework has evolved to include financial-risk considerations intended to identify customers who may be at risk of financial harm.
It is important not to lump every financial check into the same category.
A source of funds check can have a different purpose from a financial-risk or vulnerability-related check.
If a bookmaker contacts you, read the wording carefully.
Ask whether the request relates to:
- identity
- payment verification
- source of funds
- source of wealth
- financial risk
- another account requirement
Understanding the purpose makes it much easier to respond appropriately.
Are Financial Risk Checks the Same as Credit Checks?
Not necessarily.
Different checks can use different information and serve different purposes.
Do not assume that a bookmaker contacting you about financial risk means you have applied for credit or that the process is identical to applying for a loan.
If you want to know what data has been used in a particular check, consult the operator’s information and ask it directly where necessary.
Can a Bookmaker Ask What You Earn?
A bookmaker may request information about income where it is relevant to a legitimate check.
If you receive this type of request, establish:
- why the information is required
- what evidence is accepted
- which period is relevant
- how it should be supplied
- how the information will be handled
You should not provide sensitive financial information to someone merely because they claim to represent a bookmaker.
Verify the request first.
Can a Bookmaker Ask Where Your Money Came From?
Yes, a bookmaker may ask questions concerning the origin of funds where this is relevant to its checks.
Give accurate information.
Do not invent a source because you think it will be easier to explain.
False information can make the process more complicated.
Can a Bookmaker Ask for Tax Returns?
Depending on the nature of a financial check and the customer’s circumstances, an operator may request different types of supporting documentation.
If a tax-related document is requested, ask what exactly is required and why.
This can be particularly relevant for customers whose income does not come from a conventional salary.
Can a Bookmaker Ask for Business Accounts?
If funds relate to business or self-employment income, a bookmaker may request evidence appropriate to the circumstances.
However, business financial documents can contain substantial amounts of sensitive information.
Do not provide more than has legitimately been requested without understanding the purpose.
Ask the operator for clear instructions.
Is It Safe to Send Financial Documents to a Bookmaker?
Financial documents are sensitive, so caution is appropriate.
If a legitimate bookmaker requires information, use its official submission process.
Before uploading anything:
- Check you are using the genuine bookmaker website or app.
- Confirm the request within your account where possible.
- Understand what has been requested.
- Check which information needs to be visible.
- Use the official upload facility.
- Keep your account and email secure.
Do not send bank statements to tipsters, social-media accounts or unknown third parties claiming they can resolve a bookmaker problem.
Source of Funds Scams
Requests for financial documents can provide an opportunity for criminals to impersonate bookmakers.
Be suspicious if someone asks you to:
- email documents to an unfamiliar address
- disclose online banking passwords
- provide one-time security codes
- transfer money to verify an account
- pay a fee to release winnings
- give remote access to your computer
- send cryptocurrency to an unknown wallet
If in doubt, stop communicating through that channel.
Navigate directly to the bookmaker’s official website and contact customer support.
Should You Send Your Online Banking Password?
No.
Do not give another person your online banking password.
Likewise, never provide security codes to an unexpected caller or message sender.
A request for evidence about funds is not permission for someone to take control of your bank account.
What Happens If You Refuse a Source of Funds Check?
You can decide not to provide requested information.
However, if the bookmaker legitimately requires information to complete necessary checks, refusing may affect its ability to continue providing services or particular account functions.
The exact consequences depend on the circumstances.
If you do not want to provide a document because you believe the request is excessive or unclear, ask the bookmaker:
- why it needs the information
- what regulatory or account purpose it serves
- whether alternative evidence is acceptable
- which information needs to be visible
- how your information will be handled
That is preferable to simply ignoring the request.
Can a Bookmaker Close Your Account?
Bookmakers can close or restrict accounts in accordance with applicable rules and their terms.
A financial-information request does not automatically mean an account will be closed.
If the operator tells you that a check must be completed, read the instructions and ask what will happen if it cannot be completed.
Can a Source of Funds Check Affect a Withdrawal?
Account checks and withdrawals can sometimes overlap.
If information is outstanding, it may affect account processes depending on the circumstances.
If you have a pending withdrawal and receive a financial-information request:
- Check the request is genuine.
- Establish what is required.
- Ask whether it relates to the withdrawal.
- Supply legitimate evidence through the official process if you choose to proceed.
- Keep records of communication.
Our Fast Withdrawal Betting Sites guide explains the wider withdrawal process.
Can a Bookmaker Keep Your Winnings?
Do not assume that a request for documents means the bookmaker is automatically entitled to retain winnings.
The outcome depends on the facts, the reason for the check, applicable rules and account terms.
If you are in a dispute, ask the bookmaker to provide a clear written explanation.
Use its formal complaints process where appropriate.
What If a Source of Funds Check Is Taking Too Long?
First establish whether the bookmaker is waiting for anything from you.
Check:
- account messages
- document status
- requests for additional information
If you have supplied everything requested and the operator’s expected processing period has passed, contact customer support.
Keep copies or records of relevant correspondence.
If the issue remains unresolved, follow the bookmaker’s complaints procedure.
What If the Bookmaker Keeps Asking for More Documents?
Additional requests can occur if the information initially supplied does not establish what the operator needs.
Rather than repeatedly sending documents at random, ask:
What specific information is still outstanding?
Then ask:
Which document would satisfy that requirement?
This can make the process much clearer.
What If You Cannot Provide the Requested Document?
Tell the bookmaker.
For example, a self-employed customer may not have conventional payslips.
Someone using savings may have different evidence from someone whose funds came from a property sale.
Ask whether alternative documentation can satisfy the requirement.
Never fabricate a document.
Should You Edit Financial Documents Before Uploading Them?
Do not falsify, manipulate or misleadingly alter financial evidence.
If you are concerned about irrelevant sensitive information appearing on a document, ask the bookmaker whether specified information may be redacted.
There is an important difference between an operator-approved redaction and altering a document to misrepresent its contents.
How to Respond to a Source of Funds Request
If a bookmaker contacts you, use this process.
1. Verify the request
Confirm it through the genuine bookmaker website, app or official support channel.

Make sure required information is readable.
7. Upload securely
Use the bookmaker’s approved process.
8. Monitor the account

Frequently Asked Questions
What is a source of funds check?
It is a check designed to establish where relevant money comes from.

Ask the bookmaker which specific check it is conducting.
Does everyone get a source of funds check?
No. Customers can experience different checks depending on their circumstances.

Financial evidence such as payslips may be requested where relevant to a legitimate check.

Yes. The bookmaker may ask for evidence appropriate to the circumstances.
Can an inheritance be a source of funds?
Yes. If relevant, the bookmaker should explain which evidence it requires.

How long does a source of funds check take?
There is no universal timeframe. It depends on the bookmaker, circumstances, documents and whether further information is required.
What should I do if I think the request is unreasonable?
Ask the bookmaker to explain the request and use its formal complaints process if you remain dissatisfied.
Summary
A source of funds check is designed to help establish where money associated with gambling activity originates.
It is not the same as ordinary identity verification.
Depending on the circumstances, a bookmaker may ask for evidence such as bank statements, payslips or documentation relating to savings, investments or another stated source of funds.
Not every customer will receive the same request.
If you are asked for financial information, establish exactly what type of check is taking place, why the information is required and which documents are accepted.
Only provide sensitive documents through official bookmaker channels. Never give anyone your banking password, account security codes or remote access to your device.
If you cannot provide the exact document requested, contact the bookmaker and ask whether suitable alternatives are available.
