Source of funds checks at casinos

What a source of funds check at a casino is

A source of funds check is the casino asking you to prove that the money in your gambling account comes from a legitimate place, such as wages, savings, a pension, a house sale or an inheritance. It usually arrives as an email or an account message asking for documents, often with a deadline and a short list of acceptable evidence.

It is not the same as proving who you are. The identity and age checks you pass when opening an account confirm your name, address and date of birth. A source of funds check goes further and asks about your money. It is one of several checks covered on our UK casino rules hub, and probably the one that surprises players most.

The Gambling Commission’s page on age, ID and financial verification (opens in a new tab) confirms that businesses may ask for bank statements to verify the source of funds as part of anti-money laundering checks. It also says they may look for irregular income patterns, giving a pending house sale as an example.

The law behind casino source of funds checks

Casinos are one of the business types covered by the Money Laundering Regulations 2017, alongside banks, estate agents and accountants. The rules require them to carry out customer due diligence, monitor accounts and report suspicious activity. The Proceeds of Crime Act 2002 makes it an offence to handle criminal money, which is why a casino cannot simply ignore unusual deposits.

The Commission’s anti-money laundering guidance for casinos sets a €2,000 threshold. For remote casinos, identification and verification are required when a customer deposits or withdraws €2,000 or more, whether in one transaction or several that appear linked. The guidance says transactions may be linked if they happen during one logged-in period, and that operators must watch for customers splitting payments to stay below the line. Due diligence also applies once you first deposit into the casino part of a site.

The threshold is in euros because it comes from European law that the UK carried over, so the pound equivalent moves with the exchange rate. Most casinos set their own internal triggers well below it, and the Commission’s 2026 risk assessment treats thresholds that do not suit an operator’s customers, or that are based mainly on losses, as a high risk.

Casinos also hold their licences on condition that they follow the Commission’s anti-money laundering rules in the Licence Conditions and Codes of Practice. Failing to do so is one of the most common reasons for fines.

Source of funds checks compared with other casino checks

Players often mix up the checks a casino runs. They have different legal bases, use different information and start at different points.

The financial vulnerability check (opens in a new tab) is a light public-record search and does not ask you for anything. The credit-data assessments that newspapers often call ‘affordability checks’ were piloted but have not been switched on, and the Commission says that term is inaccurate. A separate explainer on so-called affordability checks explains the difference in full.

What usually triggers a source of funds request

Each casino sets its own triggers, so there is no single figure that guarantees a request. The Commission’s July 2026 risk assessment for remote casinos points to the kinds of patterns operators are expected to watch.

• Deposits that rise quickly or move well beyond your usual pattern.
• Spending that looks out of line with your declared job, which the Commission illustrates with an 18-year-old whose play appeared funded by third parties.
• Money from third parties, or from cash-intensive businesses.
• Several payment methods used in a short time, or many small deposits that together pass a threshold.
• Withdrawing after very little play, which can look like an attempt to clean money through the account.
• Joining a VIP or high-value scheme, where the Commission’s rules since 31 October 2020 require up-to-date source of funds evidence.

The VIP scheme rules are the clearest case. The Commission’s high-value customer guidance (opens in a new tab) says operators must hold current identity, occupation and source of funds evidence before treating someone as a high-value customer.

Documents a casino may ask for in a source of funds check

The Commission does not publish a fixed document list, so casinos choose what they ask for. These are the most common requests and what each one shows.

Send documents only through the casino’s secure upload area, not by replying to an unexpected email. Our guides to casino verification documents and why casinos ask for bank statements cover formats and common rejections.

How to respond to a source of funds check

1. Log in to the casino directly, not through a link in an email, and confirm the request appears in your account messages or verification area.
2. Read exactly what is being asked for and the deadline. Note any document dates the casino specifies.
3. Gather documents that match the money you deposited. If you used savings, show the transfer from savings to your current account.
4. Upload clear, complete files through the secure area. PDFs from online banking are usually accepted more readily than photos.
5. Add a short note if your situation is unusual, such as a one-off inheritance or a recent house sale.
6. Keep a record of what you sent and when, in case you need to complain later.
7. If you would rather not share your finances, you can stop gambling with that casino and ask to withdraw your balance; the casino must still handle your request fairly.

Source of funds checks in practice: worked examples

These illustrations show how the rules can play out. They are not accounts of real customers, and each casino sets its own triggers.

Example 1: steady monthly spending

Jordan earns £2,200 a month after tax and deposits £100 a month, spread across four £25 deposits. That pattern is small and stable, so a source of funds request would be unusual. The £150 financial vulnerability check would not be triggered either, because net deposits stay under £150 in any 30 days.

Example 2: an inheritance

Maria receives £12,000 from an inheritance and deposits £3,000 over one weekend, well above her usual £50 a month. Her deposits pass the €2,000 due diligence line and are far outside her pattern, so a request is likely. Probate paperwork plus a bank statement showing the money arriving would usually answer it.

Example 3: money from someone else

Leon deposits £800 a week, funded by transfers from a friend. Third-party funding is a recognised risk, and a payment in someone else’s name also breaks most casinos’ terms. The question page on using someone else’s card explains why that causes problems at withdrawal.

Can a casino hold a withdrawal during a source of funds check?

Sometimes, but there are limits. The Commission’s guidance says a business should not make proof of identity a condition of withdrawal if it could have asked earlier. Where anti-money laundering checks are needed, it should ask promptly rather than waiting until you request a payout. The exception is where the law requires a check at that point, which can happen if a withdrawal itself crosses a due diligence threshold or raises suspicion.

The Commission’s page on what to do if you can’t withdraw your winnings (opens in a new tab) adds that a business cannot confiscate your money because you did not log in or verify within a time limit. If funds are linked to suspected crime, though, the casino may be legally barred from releasing them and may not be allowed to explain why. Our guides on pending withdrawals and what to do if a casino won’t pay cover the practical steps.

Is it safe to send bank statements to a casino?

Sending financial documents to a licensed casino is as safe as sending them to any regulated business, provided you use its secure upload area. Licensed operators must follow UK data protection law and the Commission’s security standards. The bigger risk is fraud: criminals sometimes send fake verification emails to collect documents.

• Check the casino’s licence on the Commission’s public register before uploading anything; our guide on how to check a casino licence shows how.
• Never send documents to a personal email address or through social media messages.
• Ask the casino how long it keeps documents; our data privacy guide explains your rights.

Why casinos take source of funds checks seriously

Weak money laundering controls are behind many of the Commission’s largest penalties. Each of these cases, listed on the Commission’s enforcement pages, involved anti-money laundering failures alongside social responsibility failures.

The £10m Platinum Gaming penalty (opens in a new tab) is the largest in that list. The Gambling Commission fines page tracks other cases with dates.

What changed in 2026: the Commission’s latest risk view

On 30 July 2026 the Commission published its updated money laundering risk assessment for the gambling industry. It kept remote casinos at high risk and added new concerns that bear directly on source of funds checks.

• Failure to scrutinise source of funds documents properly is now rated a high risk.
• Fake documents, including AI-generated papers, deepfake videos and face swaps, are listed as a growing problem.
• Linked and duplicate accounts and inadequate checks on customers who are not physically present are both new high risks.

In practice, that points to casinos looking harder at documents, asking for originals in PDF form and checking that figures match across statements. It does not create a new player-facing rule, but it explains why requests may feel more detailed than a few years ago. Our 2026 changes guide puts this alongside the year’s other updates.

If you think a source of funds check is unfair

Start with the casino’s complaints process. Under the Commission’s rules it has 8 weeks to resolve your complaint, after which it must tell you about its independent dispute resolution service, which is free to use. Keep copies of every document and message.

An ADR service can look at whether the casino followed its own terms and treated you fairly. It cannot overrule the law on money laundering, so if a casino has made a suspicious activity report it may not be able to tell you. Our step-by-step guide to complaints and ADR explains each stage, and how to complain about a casino includes a template.

Where to play: licensed casinos that run these checks

Every UK-licensed casino must carry out money laundering checks, so a site that never asks questions is a warning sign rather than a selling point. The two casinos below are both on the Commission’s public register: Coral is run by LC International Limited (account 54743, part of Entain) and PlayOJO by Skill On Net Limited (account 39326).

Coral Casino (18+, new players, offer runs 1 October 2026 to 1 February 2027): deposit and bet £10 or more on slots to get 100 free spins worth 10p each on selected games. Accept them within 48 hours and use them within 7 days; there is no wagering on free spin winnings. PayPal, Skrill, Neteller, Paysafe, prepaid cards and certain debit cards don’t qualify. See our Coral verification guide before you sign up.

PlayOJO (18+, new UK customers excluding Northern Ireland, minimum first deposit £10): 80 free spins on Big Bass Bonanza at 10p each, with winnings paid in cash and no wagering. It cannot be combined with other offers and is only available through the designated offer link. Terms apply to both offers, and gambling should only ever be paid for from money you can afford to lose.
