TLDR The UK nearly doubled its Remote Gaming Duty from 21% to 40% on April 1, 2026, and the full financial impact has not yet hit operator balance sheets Operators are quietly lowering slot machine Return-to-Player rates and cutting bonuses, effectively doubling the cost per spin for players Two smaller operators have already exited the UK market, and mid-sized brands face serious margin pressure Industry experts warn the combined effect of higher taxes and new financial risk checks could push players toward illegal offshore gambling sites The UK Treasury expects over £1 billion in additional annual tax revenue, but critics say the policy risks destabilizing the regulated market
