The Gambling Commission issued 260 cease-and-desist notices to advertisers linked to unlicensed gambling between January 2025 and February 2026. The disclosure, published on 8 October 2026, puts illegal gambling promotion under renewed scrutiny across Great Britain.

The notices concerned suspected offences under sections 330 and 33 of the Gambling Act 2005. Section 330 covers knowingly advertising unlawful gambling without a reasonable belief that it is legal. Section 33 covers providing gambling facilities in Great Britain without the required licence.

The notices are not fines or court judgments. They are an enforcement tool designed to make illegal gambling harder to reach from Great Britain.

What the 48-hour window means

The Gambling Commission says its cease-and-desist process gives the relevant website operator 48 hours to introduce geo-blocking or another measure that prevents access from Great Britain.

The deadline was previously 14 days. The shorter window reduces the time in which an unlicensed operator, advertiser or affiliate can continue reaching British users.

The action is not a fine or a final court judgment. It is a disruption measure. The Commission can follow it with referrals to hosting companies, domain registrars, search engines and online platforms.

Advertisers are now part of the enforcement chain

The 260 notices show that the regulator is not focusing only on gambling websites. Advertisers, publishers and affiliates can also face action when they help promote unlicensed gambling accessible to Great Britain.

The Gambling Commission’s disruption report, published on 21 October 2025 and updated on 12 March 2026, says its strategy targets the wider promotional ecosystem. That includes search engine optimisation, social media, affiliate networks and advertising activity based in Great Britain.

The regulator has also warned sports organisations that sponsorship or advertising arrangements with unlicensed gambling operators can create risks under section 330. Such arrangements must ensure that the associated gambling service remains inaccessible to consumers in Great Britain.

Blocking access matters more than hiding search results

Gambling Commission data shows why the regulator is using several pressure points. Removing a page from a search engine can make an illegal site harder to find, but it does not necessarily stop direct access.

In its disruption analysis covering July 2024 to June 2025, the Commission reported an average estimated traffic decrease of 60% after geo-blocking and 91% after a registrar block or website suspension. The figures came from sites with available SimilarWeb traffic estimates. They do not measure every illegal gambling website.

  • Google removals were linked to an average estimated traffic decrease of 30%.
  • Bing removals were linked to an average decrease of 52%.
  • Geo-blocking was linked to an average decrease of 60%.
  • Registrar blocks and website suspensions were each linked to an average decrease of 91% in the reported sample.

The comparison suggests that access controls can have more force than search delisting alone. It also explains why the Commission seeks action from several companies at once.

What the 260 notices do not show

The figure does not show how many people used the affected sites. It counts regulatory notices connected with illegal gambling promotion. It is not a measure of customer numbers, deposits, stakes, losses or revenue.

The Commission has separately said that it is continuing research into consumer engagement with illegal online gambling. It declined to release some related information under the research exemption in the Freedom of Information Act 2000, saying early publication could produce an incomplete picture.

A wider enforcement campaign

The 260 advertiser notices sit within a broader campaign. Between April 2025 and March 2026, the Commission recorded 257 cease-and-desist notices to advertisers and affiliates across its quarterly data. It also recorded hundreds of referrals to search engines, platforms, registrars and hosts.

For the first quarter of the 2026 to 2027 reporting year, from April to June 2026, the Commission recorded 73 cease-and-desist notices to advertisers and affiliates. It also reported 147,721 URLs referred to search engines and 27 websites geo-blocked by operators.

These totals cover different reporting periods and categories, so they should not be added together as a single count of unique websites or advertisers.

Why the disclosure matters

The new figure gives affiliates and digital platforms a clear warning. Promotion can become a regulatory pressure point even when the advertiser does not operate the gambling website.

For consumers in Great Britain, the practical effect could be less visibility and faster removal of illegal gambling links. The disclosure also underlines the limit of the number itself: it shows enforcement activity, not the full size of the illegal market or the number of people exposed to it.
