UK regulators and the licensed betting industry have sharpened their attack on black market gambling this week, with the Gambling Commission’s most senior researcher accusing major technology companies of failing to stop illegal operators reaching British players. The renewed pressure, alongside an open letter from the industry’s main trade body, matters to anyone who plays at online casinos, because it draws attention to the unlicensed sites that sit just outside the regulated market and the protections players give up when they use them.

What is black market gambling?

Black market gambling refers to operators that take bets from UK consumers without a licence from the Gambling Commission. Many of these sites market themselves as “non-GamStop casinos”, a reference to GamStop, the national self-exclusion scheme that lets people block themselves from licensed gambling. Because unlicensed operators sit outside that system, they can accept customers who have chosen to self-exclude, which is one of the reasons the regulator treats them as a serious source of harm.

These operators do not follow UK rules on customer checks, safer gambling tools or complaint handling. The Betting and Gaming Council points out that unlicensed sites do not carry out player protection measures, do not fund research, prevention and treatment through the statutory levy, and do not pay UK tax. In short, almost everything that makes a regulated casino accountable is missing.

Why regulators are turning on Big Tech

In an interview published on 17 June, Tim Miller, Executive Director of Research and Policy at the Gambling Commission, said technology platforms are “essential” partners in tackling the black market but are not doing enough. He argued that companies act mainly when pushed, removing illegal adverts and sites only after harm has started rather than preventing them from appearing in the first place.

Miller’s frustration was blunt. “I find it almost incredible that you read in the news all of these kinds of tech billionaires competing to be the first one to put a man on Mars,” he told SBC News. “Yet, they seem to claim that they are incapable of stopping non-GamStop ads appearing on their platforms. I mean, that’s just nonsensical.”

The licensed industry is making the same point. The Betting and Gaming Council, led by chief executive Grainne Hurst, published an open letter urging platforms to remove illegal gambling adverts and to work more closely with regulators and law enforcement. The trade body set out a five-point plan covering advert removal, more enforcement resources, closer cooperation, greater transparency and stronger protection for vulnerable users.

Why this matters for players

The scale of the problem is the reason this is more than an industry squabble. Figures cited by the Betting and Gaming Council, based on analysis by H2 Gambling Capital, suggest money staked with black market operators could rise from around £17bn today to £33bn by 2028. Separate analysis attributed to WARC suggests illegal operators already account for almost half of gambling advertising spend in Britain.

For players, the practical risk is straightforward. An unlicensed casino is not bound by UK rules, so there is no guarantee that deposit limits, self-exclusion, identity checks or fair complaint handling will work as they should. If a withdrawal is refused or an account is closed with a balance inside it, there is no UK regulator to escalate to. Bonus terms can be changed at will, and money can be far harder to recover. These are exactly the safeguards that licensed safe online casinos are required to provide.

How to check a casino is licensed

The simplest defence is to confirm a site holds a current licence before depositing. A UK-facing casino should display its Gambling Commission licence details, usually in the footer, and you can cross-check the operator on the Commission’s public register. Sites that promote themselves around avoiding GamStop, or that are vague about who actually holds the licence, are a clear warning sign.

It also helps to use the tools that exist for a reason. Setting a deposit limit, using reality checks and, where needed, self-excluding through responsible gambling tools only works if you are playing with a licensed operator. Our guides to casino licences and trusted UK casinos explain what a proper licence looks like and how to read it.

What players should watch next

The next phase will test whether warm words turn into action. The Gambling Commission has a £26m budget aimed at the illegal market, is recruiting a dedicated head of illegal markets, and sits alongside operators, payment firms and tech companies on a government taskforce led by gambling minister Baroness Twycross. Expect more pressure on search engines and social networks to block illegal adverts at source, and possibly new measures to disrupt the payments and domains that keep black market sites running.

Betspin view

This is a welcome push, but the burden should not fall on players to police a market that licensed firms, regulators and platforms are still arguing over. The useful takeaway is simple. The value of a licensed casino is not the bonus on the front page, it is the protection behind it. Until illegal adverts are genuinely harder to find, the safest move is to stick to operators you can verify, and to treat any site selling itself as a way around GamStop as a reason to walk away.
