Illegal Gambling UK Set to Hit £33bn as BGC Acts

⏱ 3 min read

Britain's illegal gambling market could more than double to £33 billion in wagered stakes by 2028, according to forecasts from industry analyst H2 Gambling Capital — a trajectory that would mean roughly one in every five pounds bet online going to unlicensed operators. The Betting and Gaming Council (BGC), which represents around 90% of the UK's regulated sector, sounded the alarm on 8 June 2026 with a five-point action plan aimed at cutting off the black market's advertising, payments, and infrastructure.

The illegal market is not a fringe concern. Separate H2 Gambling Capital data shows stakes with illegal operators have already surged to £16.6 billion — more than tripling since 2019 and doubling in the last two years alone. Research by WARC adds that unlicensed operators now account for nearly half of all UK gambling advertising spend and are on course to overtake the regulated market on that metric by 2028 — well ahead of the established players that fund age-verification, safer-gambling tools, and formal dispute resolution.

The Scale of the UK Illegal Gambling Market

The numbers behind the BGC's campaign reflect a market that has grown far faster than regulators have managed to contain it. The £16.6 billion already wagered with illegal operators represents a dramatic acceleration: stakes roughly tripled between 2019 and 2025, with half of that growth packed into the last two years. Operator profits tracked the same curve, with H2 Gambling Capital finding that black market revenues also doubled between 2023 and 2025.

The consumer harm is structural, not incidental. Unlicensed operators conduct no proper age verification, offer no self-exclusion tools, carry no affordability checks, and provide no route to redress when disputes arise. The BGC also notes that illegal sites actively target people who have voluntarily self-excluded from the regulated market — exploiting the very commitment those individuals made to reduce their gambling.

The BGC's Five-Point Illegal Gambling Plan

The BGC is calling on government, the UK Gambling Commission (UKGC), social media platforms, payment providers, and technology companies to act jointly across five areas:

• Shut down illegal advertising. Require social media companies to proactively remove unlicensed gambling content before it reaches British consumers, including children and vulnerable adults.
• Block illegal websites. Grant the Gambling Commission broader powers to block unlicensed sites and remove illegal apps — illegal operators currently outpace enforcement by rapidly spinning up new domains that mirror regulated brands.
• Cut off payments. Compel payment providers to refuse transactions linked to unlicensed gambling operators, striking at the financial model that sustains the black market.
• Hold enablers accountable. Impose meaningful penalties on companies — platform hosts, payment processors, affiliate networks — that knowingly supply services to illegal operators.
• Toughen criminal sanctions. Create stronger criminal deterrents against individuals and organisations that operate or profit from illegal gambling targeting UK consumers.

BGC Chief Executive Grainne Hurst framed the issue in terms of consumer protection rather than market competition: "every customer who is driven into the black market loses those protections."

Current Enforcement Efforts — and Their Limits

The UKGC's Illegal Markets team has not been idle. Since April 2024 it has issued 3,140 cease-and-desist and disruption notices, referred 447,778 Google and Bing URLs linked to illegal gambling for removal, and secured the deletion of 287,961 URLs. Yet the black market's growth figures suggest current tools are insufficient: illegal operators can create mirror sites, rebrand overnight, and exploit encrypted communications faster than the regulator can respond.

The BGC's position is that incremental enforcement is no longer adequate — the infrastructure around illegal operators (hosts, payment rails, ad networks) must itself face legal consequences for knowingly facilitating unlicensed gambling.

Government Taskforce — First Step, Not a Fix

The BGC's campaign landed weeks after the Department for Culture, Media and Sport (DCMS) published terms of reference for a new Illegal Gambling Taskforce. The body will bring together gambling regulators, law enforcement, payment firms, and technology companies under a shared enforcement agenda, with illegal advertising and payment disruption as stated priorities.

The BGC welcomed the taskforce but argued it must translate into tangible action rather than coordination in principle. The regulated sector contributes around £6.8 billion in gross value added and £4 billion in annual tax revenue while supporting 109,000 jobs — a foundation the BGC says is actively threatened every time a consumer migrates to an unlicensed alternative.

The council also flagged a policy risk: regulations that make licensed products less attractive — through higher taxes, tighter bonus rules, or advertising restrictions — can unintentionally push bettors toward the black market. That tension will define UK gambling policy for the remainder of the decade.

If current trends continue, black market gambling stakes could exceed £33 billion within three years, with almost one in every five pounds staked online potentially ending up with illegal operators.
