No. The UK government won’t charge you anything on your gambling winnings. Whether you win £1 or £10,000, you will be paid out in full. For some lottery and progressive jackpot games, however, you may need to receive the payments in instalments over months – and most likely years. Each casino has its own specific Terms & Conditions about big payouts and it’s always best to consult with this page to ensure that you understand how big winnings are awarded to the player.
