Britain’s illegal gambling black market is expected to have capitalised on Boxing Day betting activity, according to the BGC.
Britain’s gambling black market is expected to have capitalised on Boxing Day betting activity, with as much as £100m potentially wagered outside the regulated sector in a single day, according to a warning issued by the Betting and Gaming Council (BGC).
The industry body said in a release on 26 December that the figure reflects the growing scale of unlawful betting activity and the heightened risks posed to consumers during peak sporting periods.
Analysis cited by the council, drawing on data from H2 Gambling Capital, indicates that illegal operators already process billions of pounds in stakes annually.
While a final tally for this year is not available, Boxing Day is estimated to account for around 1% of total yearly betting turnover, suggesting that tens of millions of pounds could be diverted to unlicensed sites in just 24 hours.
BGC CEO Grainne Hurst said: “Boxing Day is one of the biggest days of the year for sport and betting, and the harmful illegal black market is gearing up for a huge payday, with Brits set to stake up to £100m illegally in just 24 hours.
“That money goes straight to criminal operators who offer zero protections and pay no tax. If higher taxes make regulated betting less attractive, the harmful black market will be the only winner. That is bad for consumers, jobs and the public finances.”
Industry representatives argue that these conditions create an uneven playing field, particularly during periods of intense betting demand tied to football, racing, and other major sports traditionally scheduled on Boxing Day.
New taxes exacerbate black market concerns
Concerns have intensified following recent fiscal changes announced in the UK’s Autumn Budget.
The government’s independent forecaster, the Office for Budget Responsibility (OBR), has acknowledged that higher gambling taxes are likely to reduce expected revenues as some consumers migrate from regulated operators to illegal alternatives.
The OBR has projected that this behavioural shift could result in a reduction of forecast tax receipts by roughly one third by the 2029-30 fiscal year, including an estimated £500m shortfall as early as next year.
Further modelling conducted by EY suggests the combined impact of recent tax measures could push more than £6bn in betting stakes into the black market.
That analysis estimates a 140% expansion of illegal gambling activity and warns that nearly 17,000 jobs across the regulated online betting and gaming sector could be put at risk as a result.
The regulated betting and gaming industry currently operates under strict requirements covering affordability checks, player safety, and anti-money laundering controls.
It supports more than 109,000 jobs nationwide and contributed £6.8bn to the UK economy prior to the latest Budget, alongside annual tax payments of around £4bn. The sector also provides significant funding for British sport, horse racing, and tourism.
By contrast, unlicensed operators function entirely outside the regulatory framework while continuing to target UK consumers.
The BGC has urged policymakers to engage with the licensed industry to ensure that consumer protection measures, like those currently being implemented, do not inadvertently drive demand toward unlawful markets.
