Key Highlights
- Unregulated gambling stakes in Britain have surged to £16.6 billion, representing more than a threefold increase since 2019, based on data from H2 Gambling Capital presented by the Betting and Gaming Council.
- Stakes placed with offshore betting platforms doubled during the two-year span from 2023 to 2025, marking the most dramatic expansion period.
- Licensed operators’ market dominance has declined from 97% in 2019 to 92% in 2025 as gamblers increasingly turn to unlicensed platforms.
- Unlicensed gambling platforms now represent almost half of total UK gambling advertising expenditure and are projected to control the majority share within 24 months.
- Industry representatives argue that increased taxation, stricter regulatory requirements, and proposed financial screening measures are driving consumers toward unregulated operators lacking consumer safeguards.
The unregulated gambling sector in Britain has expanded dramatically to £16.6 billion in total stakes, new data from H2 Gambling Capital reveals. The Betting and Gaming Council, which represents licensed gambling businesses operating in the United Kingdom, released the findings.
The unlicensed market has grown more than threefold since 2019. The expansion has doubled within just the past two-year period, with the most aggressive growth trajectory observed from 2023 through 2025.
Meanwhile, the proportion of gambling conducted through licensed platforms has experienced a corresponding decline. Licensed operators controlled 97% of total gambling activity in 2019. That percentage has now contracted to 92%.
Unlicensed Platforms Expand Market Position
Stakes channeled through offshore gambling operations climbed from approximately £5 billion in 2019 to £16.6 billion in 2025. Profits generated by these unlicensed platforms also experienced a twofold increase between 2023 and 2025.
Additional data from WARC indicates that unlicensed operators currently represent nearly half of total gambling advertising expenditure throughout the UK. Projections suggest this proportion will exceed 50% within the coming two years.
These unlicensed platforms remit no taxation to UK authorities. They also provide none of the consumer protection mechanisms that licensed operators must implement by law.
The expansion has been attributed to several factors: elevated tax burdens on regulated operators, increasingly stringent operational requirements, and pending proposals for financial risk screening of customers.
While these initiatives aim to enhance consumer protection, they have diminished the competitive position of the legal marketplace. Unlicensed operators have capitalized on this opportunity.
They have increased their online visibility and adopted more aggressive approaches to targeting UK customers. Their promotional strategies have become increasingly refined in recent years.
Grainne Hurst, Chief Executive of the BGC, emphasized that the trajectory should concern anyone prioritizing consumer welfare. She characterized a dangerous black market that is expanding rapidly.
Hurst cautioned that consumers will not cease gambling activities if the regulated sector becomes more restrictive. Instead, they will migrate to unprotected platforms offering no safety measures.
Industry Group Advocates for Regulatory Equilibrium
The BGC has specifically criticized proposed financial risk assessment requirements. Hurst emphasized these verification processes must be “genuinely frictionless” or should not be implemented.
Anything less effective, she contended, would accelerate customer migration from the regulated marketplace toward offshore operators.
The organization emphasized that initiatives designed to minimize gambling-related harm require careful calibration. Excessively restrictive regulations risk inadvertently strengthening the black market they intend to combat.
The licensed gambling sector currently generates £4 billion annually in tax contributions to the UK government. The BGC has cautioned that this revenue stream faces jeopardy if the legal market continues contracting.
Unlicensed operators provide zero contribution to this tax revenue. They also operate beyond the jurisdiction of UK regulatory authorities.
The discussion emerges as policymakers evaluate additional gambling reform measures. The government has been examining various initiatives following its gambling white paper publication.
The H2 Gambling Capital research injects renewed urgency into these deliberations. The statistics indicate the black market is expanding more rapidly than many analysts anticipated.
As of 2025, unlicensed gambling stakes throughout the UK total £16.6 billion, with the BGC cautioning that absent thoughtful policy implementation, this figure will continue escalating.
