As a payments analyst, I look at withdrawals all day. When money moves slowly outside the UK system, it's rarely a mystery. It comes down to payment rails, compliance checks, and the specific rules of the licence the operator holds.
To understand why your payout is behaving the way it is, you need to look at exactly what it means when a site operates outside the UK national self-exclusion scheme.
What GAMSTOP is and Who Runs It
GAMSTOP is the UK national online self-exclusion scheme. It's a centralised, independent database that allows players to restrict their own access to gambling sites for a set period.
It isn't a regulator, a licensing body, or a government department. Instead, it's a tool operated independently by a non-profit organisation, designed to give players a single point of contact to block themselves from gambling platforms.
When you register your details with the scheme, that data is held securely. Operators then cross-reference their own registration and login attempts against this central database to prevent excluded individuals from accessing their accounts.
Why it Binds Only Ukgc-licensed Operators
The scheme gets its authority from a specific legal mechanism: participation is a mandatory condition of holding a UK Gambling Commission (UKGC) licence.
If an operator wants to legally base themselves in the UK and hold a UKGC licence, they must integrate their systems with the database. They're required by their licence conditions to check every new registration and every login against this list.
If a player is on the list, the operator must block access. Because this requirement is written directly into the UK regulatory framework, it therefore binds ONLY UKGC-licensed operators.
What That Means in Practice for a Site Licensed Elsewhere
Sites licensed elsewhere aren't connected to it. That's the entire legal basis of the phrase "not on GAMSTOP".
If a casino holds a licence in another jurisdiction, they aren't bound by UKGC licence conditions. They don't have access to the UK self-exclusion database, nor are they legally required to check it.
This means the phrase simply describes an offshore-licensed casino. It's a statement of jurisdiction and regulatory geography. It isn't a specific type of software, a special category of gaming, or a unique payment platform.
Why Your Withdrawal is Actually Slow: the Payments View
When you play outside the UKGC system, the mechanics of getting paid change. If your money is delayed, it's usually down to one of the following verified mechanics.
The Pending Window and Reverse Withdrawals
Many casinos hold a requested withdrawal in a pending state for a set period. During this time, the player can cancel the request and return the funds to their playable balance. This is known as a reverse withdrawal.
This pending window is a common cause of a payout appearing slow, and it's entirely under the player's control. A casino that offers no reverse withdrawal, or a zero pending period, pays out faster in practice. If your funds are sitting in pending, the actual payment processing hasn't yet begun.
Identity and Source of Funds Checks
KYC (identity verification) completed BEFORE the first deposit removes the largest single delay from the first withdrawal. Most published "withdrawal times" assume an already-verified account and are measured from the moment of operator approval, not from the moment you click withdraw.
However, Source of Funds (SOF) checks are the single most common cause of a genuinely delayed payout. They're a strict anti-money-laundering obligation, not an operator stalling tactic.
An SOF request typically asks for evidence of where the deposited money came from, such as bank statements or payslips. Until the compliance team is satisfied, the payout doesn't move, regardless of the advertised withdrawal speed.
Payment Rails and Weekend Gaps
Payment-rail settlement is a separate step from operator approval. Total time equals operator approval, plus the pending reverse window, plus rail settlement. Named rails behave very differently.
Card payouts via Visa Direct or Mastercard Send (an Original Credit Transaction, or OCT) are a push-to-card rail and settle faster than a standard card refund. UK bank transfers over Faster Payments settle far quicker than legacy BACS. E-wallets are generally the quickest leg because there's no bank clearing step involved.
Crucially, bank rails don't clear on non-business days. A payout approved on a Friday evening can sit until the next working day even when the casino itself has already approved it. E-wallet and crypto rails aren't subject to this weekend gap.
Crypto Confirmations and Currency Conversion
Crypto payouts aren't instant by definition. The payout is complete only after the required number of network confirmations, and that count is set by the casino's risk department, not by the blockchain. A casino requiring more confirmations pays out more slowly on the exact same network.
Additionally, an offshore casino frequently settles its accounts in EUR or USD. A GBP player can therefore lose a percentage of the payout to currency conversion at the casino, the payment rail, or their own bank. A headline "no fees" claim doesn't cover the FX spread.
Withdrawal Limits
Withdrawal limits cap how fast a large win can actually leave the account, independent of processing speed. These are typically structured per day, per week, or per month.
A large balance released in capped instalments takes far longer to reach you than the advertised per-transaction time. Always check the terms for these caps before assuming a large balance will arrive in a single swift transaction.
What You Keep and What You Lose Outside the UKGC System
When you play at sites outside the UKGC system, the rules of engagement shift entirely. You must understand what protections remain and which ones you leave behind.
First, you lose access to the UK dispute and complaint route. UKGC-licensed operators must offer an approved alternative dispute resolution (ADR) route, and UK players can escalate unresolved issues there, typically via IBAS.
Operators licensed outside the UK aren't in that system, so the UK dispute and complaint route isn't available. Any complaint route depends entirely on the terms of the licence the operator actually holds.
Second, you'll experience differing responsible-gambling tooling. While UK sites mandate strict deposit limits, reality checks, and mandatory timeouts, offshore sites typically offer a different suite of tools that rely more heavily on player initiation.
Finally, complaint handling is entirely reliant on the offshore regulator. These jurisdictions may have entirely different standards for response times, evidence gathering, and player communication than you're accustomed to in the UK.
How to Verify a Licence Properly
Because you rely on the offshore regulator for dispute resolution, verifying that licence is a critical step before depositing funds.
Curacao is the most common jurisdiction for offshore sites, and its licensing changed significantly under the LOK (Landsverordening op de Kansspelen) reform. The regulatory market there has been entirely restructured to improve oversight.
The Curacao Gaming Authority (CGA) now issues licences directly, replacing the older master-licence and sub-licence arrangement.
A licence issued under the new regime is verifiable directly with the authority, usually via a dynamic digital seal located in the website's footer. An older sub-licence isn't equivalent, and you should always prioritise operators holding direct, verifiable authorisation.
UK Tax Treatment of Winnings
One area that remains straightforward is your tax liability. Gambling winnings aren't taxed as income for players in the UK.
This fundamental rule is unaffected by where the operator is licensed. Whether the casino is based in London, Malta, or Curacao, the money you win isn't subject to income tax or capital gains tax.
Duty is levied on operators, not on player winnings. Therefore, from a UK tax perspective, what you win is typically exactly what you keep.
If You're Self-excluded and Looking for a Way Around It
If you're on the self-exclusion register and are reading this to understand how offshore sites work, it's worth pausing.
Registering for self-exclusion was a protective decision you made for a reason. Bypassing that restriction carries financial and emotional risks, as offshore sites don't offer the same mandatory safety nets.

FAQ
Are Sites Not on Gamstop Legal for UK Players to Use?
It isn't a criminal offence for a UK resident to play at an offshore casino. However, the site itself operates outside UK jurisdiction and doesn't hold a UKGC licence. This means you don't have the legal protections or dispute resolution services provided by UK law.
Why Do Offshore Casinos Ask for Source of Funds?
Source of Funds (SOF) checks are a mandatory anti-money-laundering obligation enforced by international financial regulators. The casino must verify that deposited money comes from legitimate sources, such as a salary or savings. Until this compliance check is satisfied, withdrawals are paused.
Can I Cancel a Withdrawal at a Non-gamstop Casino?
In most cases, yes. Many offshore casinos utilise a pending period where a requested withdrawal can be reversed by the player. If you reverse the withdrawal, the funds return to your playable balance and the payout process is cancelled entirely.
Do I Have to Pay UK Tax on Offshore Casino Winnings?
No, gambling winnings aren't taxed as income for players in the UK. This rule applies regardless of where the casino is licensed or located. Tax duties are levied on the operators providing the service, not on the individuals withdrawing their winnings.
