UK Illegal Gambling Market Surges to £16.6bn as Regulated Share Falls Amid Rising Black Market Activity

The illegal gambling market in the United Kingdom has expanded sharply, reaching an estimated £16.6bn (US$22.5bn), according to figures from H2 Gambling Capital that were shared by the Betting and Gaming Council. The latest estimate reflects a dramatic rise compared with £5bn ($6.79 billion) in 2019, signalling what analysts describe as a rapidly accelerating black market in the country.

Over this period, illegal gambling activity has more than tripled, with growth doubling specifically over the past two years. The most recent increase between 2023 and 2025 is reflected not only in total stakes but also in operator profits, suggesting sustained expansion and growing penetration of unregulated platforms despite enforcement efforts.

At the same time, the share of gambling activity conducted through regulated operators has declined from 97% to 92%, indicating a measurable shift in consumer activity toward unlicensed alternatives.

Analysts have pointed to a combination of contributing factors behind this trend, including tighter regulatory frameworks, higher taxation levels, and the increasing availability of illegal online gambling platforms. Additional data from WARC suggests that unlicensed operators now account for nearly half of all gambling advertising directed at UK consumers, with expectations that this proportion may continue to rise.

The Betting and Gaming Council has voiced strong concern over the expansion of the black market, warning about the risks associated with unregulated gambling platforms. These operators, which fall outside UK legal oversight, are described as avoiding taxation, lacking consumer protections, and not complying with standards required of licensed gambling firms.

Grainne Hurst, chief executive of the Betting and Gaming Council, said: “What we are seeing is a harmful black market scaling up at pace. Illegal operators are becoming more sophisticated, more visible and more aggressive in how they reach UK customers.”

She added: “If the regulated sector becomes harder to use or less competitive, customers will not stop betting; they will simply go elsewhere.”

The industry body has also raised concerns about proposed financial risk checks, warning that if such measures are not implemented carefully, they could unintentionally push more users toward unregulated gambling markets.
