What are the top new online casinos in the UK?

A refer-a-friend bonus rewards existing players for introducing a new customer who registers and meets the qualifying conditions, usually a deposit threshold. Offered to existing players on a subsequent deposit, typically as a lower percentage match than the welcome offer. Any winnings from the bonus are paid directly as real cash, with no wagering required. Wagering requirements apply to bonus funds and/or free spins winnings unless stated otherwise by the operator.

Live casino bonuses are made for players who like playing games like roulette or blackjack. Christmas is the most festive time of the year, and online casinos celebrate it in style with various Christmas casino bonus offers. UK players ask the same questions about online casino bonuses over and over. More casinos are starting to offer welcome bonuses tailored for bingo games and players.

Casino bonuses with free spins without making a deposit

Missing this step usually means losing the offer entirely, with little recourse. Enter it at registration or on the deposit screen, not after your deposit has been processed. If you’re a casual or occasional player, short expiry windows are worth paying attention to. Free spins typically expire within 3–7 days of being credited – some in as little as 24–48 hours. Always check the specific max bonus conversion limit before claiming any bonus. The latter significantly increases the total playthrough.

For a comprehensive overview, read our beginner’s guide to casino bonuses. Knowing which type of casino bonus suits your playing style can save you time and boost your gaming experience. Every casino bonus comes with specific bet limits that can affect your gameplay strategy. If slots are your preferred game, no-wagering bonuses should be your first choice.

Free spins can have tighter game restrictions than bonus funds. I’d check that list before claiming, especially if there are particular games you want to play. You can get these offers when you first join a casino or later as a reload or other promotion. That’s usually free spins or a small amount of bonus cash. A no deposit bonus is another option if you want to try a casino before spending anything at all.

A £200 bonus at 10x requires £2,000 in total bets before any winnings can be withdrawn. All offers featured on this page are reviewed regularly and sourced from UKGC-licensed operators. A smaller bonus with straightforward conditions will often deliver better value than a larger offer with stricter restrictions. Always deposit only what you can afford to lose and review the full promotional terms before claiming an offer. Casino bonuses should be viewed as an extra feature rather than a reason to gamble.

Always check the game eligibility list and wagering contributions before you commit. And even then, those games might only contribute part of your wager total. Slots usually help you out 100%, while table games often crawl along at 10–20%.

We open real accounts, claim real bonuses, test customer support, and make real withdrawals.
