A 100% deposit bonus is the most common type of casino welcome offer in the UK. It matches your first deposit pound for pound — deposit £50 and play with £100. This straightforward promotion is offered by the majority of UKGC-licensed casinos, with maximum match amounts typically ranging from £50 to £500.
How 100% Deposit Bonuses Work
The casino matches 100% of your qualifying deposit up to a stated maximum. If the bonus is 100% up to £200 and you deposit £200, you receive £200 in bonus funds for a total balance of £400. Smaller deposits receive proportionally smaller bonuses.
All 100% deposit bonuses come with wagering requirements, typically 30x to 50x the bonus amount. This means a £100 bonus at 35x wagering requires £3,500 in bets before withdrawal.
