Bonus Guides

Recommended Online Gambling Sites

Four online casinos manage very high marks from Bonus Source's team of gambling experts. These UK-friendly casinos have clear bonus rules and brilliant slots & live dealer games. LeoVegas is a smashing new casino to enter the UK - it's fantastic on mobile. Stalwart Party Casino caters to UK players superbly and offers a juicy VIP program. 21.com is an up-and-coming site worth keeping your eye on. Zodiac Casino is the best choice for anybody aiming to make small casino deposits (£1 in this case).

Free Money Guides

Our bonus guides put more free money in your pockets. And not just money. By taking advantage of the online casino promotions at Bonus Source you’ll also receive real-money free spins. Have a look at our bonus offers and get exclusive free spins from UK's #1 Bonus Source.

Poker & Sports Betting

Sport betting and online poker require detailed bonus information. The terms and conditions, also called “the small print nobody reads”, can make or break a poker or a betting promotion.
As long time poker players and sports bettors we know how important the small print can be. That’s why we read it and only choose valuable bonuses to our poker and betting bonus lists.

The Best UK Online Casinos 2019

Before you start gambling online, you need to know where you’re playing. Just any site won’t do, as it’s clear there are good and bad casinos online.

That’s why we’ve taken the time to review the ones that you might not have heard of as much. We’ve decided to keep your run-of-the-mill shops like Ladbrokes and Paddy Power completely off the UK’s #1 Bonus Source. We get them fed much too much on the telly and papers anyway.

That’s not to say they’re bad apples. They’re proper sites and do their marketing well. But when we talk about the traditional British online casinos, we’ve only included Betway and 888 Casino on our website. So, why is that?

Both of them bring something new and unique to the table. Betway has established itself as the go-to bookie for eSports betting (and some could argue for darts, too), and 888 Casino has their own jackpot slots you won’t find anywhere else. Both of them do well on other fronts too, as you can read from our 888 Casino and Betway reviews.

Which Ones Are the Best Online Casinos?

  • LeoVegas
  • PartyCasino
  • 888 Casino
  • Rizk

The top online casino list changes constantly, but there are a couple of go-to casinos that are big British favourites (and ours) year in, year out. The list isn’t long, but with these standout online casinos, you can’t go wrong. Let’s have a quick look at each one.

LeoVegas

The best mobile casino in the UK. Period. In 2019 it’s essential for the online casino to work seamlessly on mobile, and LeoVegas does just that. Add in the juicy bonuses (with no bonus code), and we’ve got ourselves a real winner.

They have all the bases covered, as they’ve got a massive amount of online slots, a live casino and they’re a quality bookie, too.

PartyCasino

PartyCasino could well be the best overall online casino in the UK for 2019. They don’t mess about with their identity, as they’re offering everything one could hope for when it comes to online slots and live casino.

888 Casino

888 deserves its place at the top of the list. For a while there it seemed like they’d dropped out of the running as their software was outdated and couldn’t stand the test of time, but in 2019 they’ve kicked into another gear.

They continue to serve Brits well, and their experience shows in the business they conduct: quality customer service, fast withdrawals and well-working platform on all devices.

Rizk Casino

Rizk is a relative newcomer to the UK, but they’ve already made waves with their state-of-the-art online casino. Rizk is almost as good on mobile as LeoVegas is, and their slots selection is downright huge.

They especially excel in fast payouts. They promise to process cashouts within two hours, and we’ve noticed they tend to be far faster than that. Usually it’s minutes, not hours. That’s what we like to see.

Only Reputable & Legit Online Casinos

You might’ve not heard of the likes of Zodiac Casino or Karamba, but we guarantee they’re fine destinations if you’re a slots player or enjoy a smashing live casino.

We’ve included only the best casinos that are licensed in the UK while keeping an eye on the up and coming sites just about to enter Great Britain. As we’re one of the most competitive and harshly legislated markets in all of online gambling, new casinos go under heavy scrutiny before they’re allowed to accept UK customers.

The rules are simple: if a casino doesn’t have reputable owners or they’re just aren’t backed enough, they don’t stand a chance. During the last 20 years in online gambling, we’ve seen rubbish casinos enter the market and exit just as quickly. It’s only a good thing for us as players to have UK Gambling Commission keeping a close eye on these chaps. They weed out rotten operators.

We monitor all the sites listed at Bonussource.com via our anonymous tests and by reading player forums. We take these steps to ensure only top-quality online gambling sites get listed.

Our rankings and casino reviews are updated and tweaked every week. Yes, we do follow the gaming market that closely. You will find the full list of online casino bonuses here.

New UK Casinos?

Now that’s a proper shortlist.

We’ve managed a sneak peek on all of the newcomers, and we can tell you there’s plenty of goodies to come, especially for slots players. Check out our reviews of all of the three to find your casino if you’re looking for a brand new casino to play in.

Please note not all of them are accepting UK players just yet, but that time will come very soon.

Expert Gambling Opinions

Be it casino gambling online, sports betting, bingo, or poker; we know what separates a lousy bonus from a good one. Of the good ones we recommend only the very best promotions.

uk casino bonus codes

The Internet has changed the way we gamble. Live dealer casinos are a new way of enjoying the thrills of Roulette and Blackjack from the comfort of your own home, even on your phone. Visit LeoVegas for the best live casino experience.

Check the top menu, and you’ll find that we have strict criteria. Out of hundreds of online casinos we review, only a handful earn the coveted “recommended by Bonussource.com” status.

Get No-Deposit Bonuses

These are the most coveted bonuses that online casinos feature, and we work hard to find you new ones. They give you real money to play with for absolutely free. Often no deposit casino bonus promotions also feature big deposit match-up bonuses, so you’ll get the best of everything.

Online Gambling Bonus Codes for UK Players

On this site, you’ll find the real-money casino bonus codes available at UK licensed online casinos right now.

We only list no-deposit and other bonuses, which give you real money. Real money means that you can cash out what you win. If you couldn’t enjoy the money you win, there’s no point to the whole bonus.

Be aware that some casinos have so-called “no deposit promotions,” where the free money you receive is actually bonus money. In practical terms, this means you need to make a deposit and wager real-money to cash out your no-deposit bonus winnings. We don’t consider these as true “no deposit bonuses” and don’t list them on our site.

While no-deposit bonus codes are rare at online casinos, many casinos feature promotions where you get a lot for very little money. These deposit bonuses are often much better deals than those that don’t require depositing.

Just a couple of examples of what a good bonus code gets you:

Criteria for The Best UK Online Gambling

This is what safe online gambling is all about: Trustworthy online operators, excellent benefits for new players and great VIP club offers for all.

safe online casino

We get a lot of questions when it comes to the safety of online casinos. We only promote the operators with a solid reputation amongst British gamblers all over the world.

Shady terms and conditions, history of customer complaints and slow response times, slow withdrawals when trying to cash out your winnings… The list of things you encounter at bad online casinos is endless. We dislike all these things as much as you do, so we only recommend legit casinos.

We do the dirty work and test all the UK licensed online casinos and gambling operators online. Bonussource.com only publishes reviews of the websites that have their act together.

This is the minimum criteria UK online casinos need to pass:

  • Licensed by the UK Gambling Commission
  • Fair and responsible online gambling
  • Responsive customer support
  • Play in Sterling
  • Clear bonus rules
  • Fast payouts
  • Full support for Android/Apple mobile gambling
  • Instant deposits and fast payouts with Paypal, Neteller or bank cards

And, of course, the site should have great slots, scratch cards and other gambling games to keep you entertained.

Online Gambling FAQ

Is it legal to gamble online in the UK?

Absolutely. It’s become the norm. The UK is probably the most advanced country in the world when it comes to regulating online gambling. The UK Gambling Commission does its work well and doesn’t allow bad operators to accept UK players.

Nowadays you can’t even access an unlicensed casino. As most of the online casinos hail from Malta, UKGC has come to a fair deal with the Maltese Gaming Authority that the casinos under an MGA license don’t accept UK customers at all.

Can you win real money by playing online slots?

All online casinos pay out real-money slot winnings. You can even win up to millions of dollars when you play progressive jackpot games, such as the aforementioned Mega Moolah or Mega Fortune. We’ve even had a British ex-soldier win an astounding 13 million quid for a measly 25p! This chap got his massive score at Betway Casino.

Can I gamble online with my mobile phone?

Not only is it possible, but mobile gambling is more popular than playing on a desktop computer or laptop.

The best part is, you don’t need to download an app to gamble on your phone. You also don’t need extra accounts. Casino sites support instant play on your default browser, no matter if you’re an iOS (Apple) or Android (Samsung, Google, Sony, etc.) user.

Here’s how you can play at a real-money online casino on your phone:

  1. Choose a casino site to play at
  2. Register an account at the casino’s website
  3. Make a deposit
  4. Enjoy the games

Note that you don’t need to download an app. All gambling is done at the casino’s website. All bonuses online casinos hand out are the same, regardless of whether you gamble on a mobile device or computer.

How can I deposit at an online casino?

  1. Choose a casino at Bonussource.com
  2. Register an account at the casino
  3. Visit the cashier by tapping “Deposit”
  4. Use any bonus code this casino might have
  5. Receive your bonus and start playing

This whole depositing process is made extra easy by UK online casinos support for popular banking methods. You can use, for example, major credit cards like Visa/Mastercard, Skrill, Paypal, Paysafecard, or you can even play at pay by phone casinos.

How fast are casino transactions?

Deposits are practically always instant. Withdrawals take from two hours up to five banking days, the exact time depending on your withdrawal method. There are also differences in how fast different online casinos process withdrawals. Finally, withdrawal times depend on how quickly you provide casino the documents they require.

When you deposit with Paypal, Visa/Mastercard, Neteller or Skrill, the deposits are instant.

When you take money out, the processing time of casinos will vary. We give especially high marks to Karamba and Rizk Casino for their A+ quickness on handling withdrawals.

How fast you see money in your account also depends on the withdrawal method and how quickly you supply the casino with the documents they request (gambling sites are obligated to check your identity when you cash out more substantial amounts).

Do I always need a bonus code when claiming a welcome bonus?

Not always. When you sign up through Bonussource.com, you’ll rarely need to know a bonus code to claim the bonus. When a casino requires a bonus code, we’ll provide that for you, and you’ll get the promised bonus.

Out of the best-known UK online casinos, not many use a bonus code these days. PartyCasino is one of the few casinos who still use them. Especially newer online casinos like Rolla.com have completely forgotten about bonus codes.

Let’s face it. Things get a whole lot easier when you can sign up and receive the same bonuses without a bonus code. Just remember to use Bonussource.com as your go-to bonus source, as we’ll always provide you with the best and up-to-date bonuses.
