A report commissioned by the Betting and Gaming Council and produced by H2 Gambling Capital forecasts UK offshore gambling stakes rising from £16.6 billion in 2025 to £36 billion by 2031. It also puts offshore revenue at £685 million this year, rising to £1.4 billion by the end of the period.
The same report says onshore “GGY channelisation” has already slipped from 97% in 2019 to 92% in 2025, and could fall further to 85% by 2031. It links that projected decline to the rise in remote gaming duty to 40% from 1 April 2026 and to a further remote betting duty increase due in 2027.
The UK government set out the tax changes in a summary of responses published in November 2025. That package raises Remote Gaming Duty from 21% to 40% from April 2026 and creates a new remote betting rate of 25% from 1 April 2027 within General Betting Duty.
Remote UK horseracing bets will remain taxed at 15%. That carve-out leaves one part of remote betting on a lower rate even as the wider remote gambling tax regime tightens.
Grainne Hurst, the Betting and Gaming Council’s chief executive, said the only winners from these tax hikes will be “criminal operators based overseas”.”,
