£300 welcome bonuses explained

As competition grows in the online casino industry grows more competitive, the biggest brands and latest casinos are constantly searching for new and innovative ways to stand out. Casino welcome bonuses are a great way to attract new customers and keep existing players coming back, and matched deposit offers are a tried and tested method that ranks among the most enticing offers. These bonuses see online casino operators offer players a percentage of the cash they deposit, up to a certain amount.

Percentages can vary from 50% to as much as 300%, so there’s plenty of variation in the deals on offer. For example, with a ‘100% deposit match up to £300’, you’d need to deposit £300 to claim the £300 bonus. Alternatively, if a casino offers a ‘200% match up to £300’, you’d only have to deposit £150 to claim £300 in bonus funds. Most casinos will reward the whole £300 bonus in one go, though it’s always worth checking the terms to see whether the bonus is split across the first, second deposit and third deposit.

While the 200% match offer may seem more attractive at first, terms and conditions like wagering requirements can mean that isn’t always the case.

Why claim a £300 welcome bonus?

There’s a number of advantages that come with claiming a £300 casino welcome bonus.

Budget boost

You don’t need us to tell you that an extra £300 equates to lots of bonus playtime on your favourite casino games. Whether you fancy spinning the slots or going against the house on in the live casino, you’ll be able to use your £300 bonus funds to play a whole range of great titles at our recommended UK casinos.

Play new games

Bonus funds are ideal if you fancy trying out a game for the first time without putting any of your real money deposit on the line. You can use your £300 matched deposit bonus to trial run new titles or different variations to find out whether they’re to your taste. Of course, you can always play free casino games to try these out, but using bonus funds gives you the chance to add to your bonus winnings while you experiment.

Chance to win

An online casino £300 welcome bonus probably wouldn’t attract many new players if it didn’t offer a chance to win real money returns. You’ll have to complete the wagering requirements first, which isn’t exactly a walk in the park, but manage that and you’ll have the chance to withdraw your bonus winnings.

Claim your £300 bonus on your mobile

Prefer to play casino games on your mobile? Good news – you can also claim your £300 bonus via mobile at the top casino sites. If you’re looking for the smoothest and most convenient mobile casino experience, we’d recommend checking out casino mobile apps. These can be downloaded for free on iPhone and Android, and have the added benefit of push notifications to ensure a casino bonus never passes you by.

Best new casinos with a £300 welcome bonus

It’s not only the best established casinos that offer £300 bonuses to new players – you can get your hands on this generous offer a number of top new casinos too. This is great news for casino fans, as it means you have more options to choose from when you’re picking out your ideal site. New casinos often seek to attract customers by offering player-friendly bonus terms, such as low wagering requirements, so they’re definitely worth considering.

Bonus terms and conditions

Understanding the bonus terms and conditions is the key to judging the true value of a casino offer- here’s what you need to know.

Wagering requirements

You’ll need to complete the wagering requirements if you want to cash in on any bonus winnings. These state how many times you need to wager your bonus funds before you can withdraw them as real money. So if your £300 bonus has a 30x wagering requirement, you’ll have to wager £6,000 before you can get your hands on any winnings as cash. At some casinos the wagering applies to both the bonus amount and your first deposit, which means you’ll need to wager more before you can cash in.

Wagering contribution

Different games will be weighted differently in terms of how much of your stake counts towards satisfying wagering requirements, with slots usually contributing a higher percentage than table games. For example, if the wagering contribution for blackjack is 10%, only 10p of every £1 bet will go towards completing the wagering.

Warning banner: Some casinos exclude certain games altogether from the wagering contribution.

Game restrictions

You’ll usually be able to use your £300 casino welcome bonus on a wide range of titles, from slots to live dealer games. However, some bonuses can only be used on certain games, so it’s worth checking that the eligible options match your playing preferences.

Maximum win caps

Casinos are usually fairly generous when it comes to £300 bonuses and let players claim winnings well into the thousands – provided they complete the wagering requirements. That being said, the maximum win limit does vary from site to site, so make sure you look out for this in the small print.

Time limits

All online casinos limit how long you have to use your bonus funds and meet the wagering requirements. It’s fairly common for £300 matched deposit bonuses to have a 30 day expiry limit, but these restrictions do differ between casinos.

Payment method restrictions

The best online casinos offer a wide range of payment methods, from PayPal to paysafecard.  However, some payment methods—usually Neteller and Skrill—are often excluded from bonuses and promotions.  Always check that your preferred payment method is accepted as part of a bonus scheme before you sign up to avoid any surprises later on.

Frequently Asked Questions

  • Yes. While there’s plenty of opportunities for existing customers to claim reload bonuses and VIP rewards, these will usually offer smaller amounts. £300 matched deposit offers are almost always exclusive to new players making their first deposit.

  • Sure – some of the best online casinos offer players the chance to claim £500 in bonus funds, and you can even bag up to £1,000 in welcome bonus funds at some sites. Of course, usually the more you want to claim the more you’ll have to deposit, so it’s all about finding the bonus that best matches your budget and playing preferences.

  • Yes. While some casinos offer low wagering and no wagering bonuses, these are usually for smaller bonus amounts. This is because any winnings from no wagering bonuses can be withdrawn right away, so a casino would risk making a big loss from a £300 no wagering bonus.

  • Yes. Many top £300 welcome bonus casinos offer free spins as part of the welcome package, affording you bonus play time on slot games too. Just keep in mind that the free bonus spins are often subject to different terms to the £300 bonus and may be exclusive to a specific title.

  • Generally, you’ll be able to keep the £300 casino welcome bonus as well as the winnings if you manage to complete the wagering requirements. We’d always advise double checking the terms and conditions just to be sure, though.
