Who Are BonusFinder?

We are a group of gaming enthusiasts who have been working in the gambling industry for over a decade, either as professional players or working with major international casinos. We set up the BonusFinder site to help ordinary players get the most out of their casino experience, by sharing our knowledge and presenting you with the best UK bonuses and free spins all in one place.

We only recommend casinos that we have tried and tested ourselves, and we compare the strengths and weaknesses of each site to help you make an informed decision before you play for real money.

Why Trust Our Opinion of the Best Casinos?

As well as being gambling experts, we also love playing live casino games and slots, so we are well aware of what makes a good gaming site. We have an extensive checklist when we rate a casino, and always consider the following:

Every casino we list is fully licensed by the UK Gambling Commission, and uses the latest encryption software to keep your data and money safe.
We check the small print in the bonus T&Cs carefully to make sure they are player friendly, and highlight any significant terms to you on our list
Before writing a review our testers fully audit a casino site. What we say is based on our first-hand experience of playing online.
We make sure that the casino site works well in terms of speed and performance on desktop, smartphones and tablets. We test drive both the website itself and the mobile app if available.
Our ranking criteria takes into account a number of factors, and is therefore unbiased and independent from the casino operators.
Our list of bonuses is verified and updated every single week. You will always get the latest offers and current promo codes from our site.

How To Choose The Best Casino For You?

Although we provide you with all the information you need to compare the latest UK casinos and bonuses, you should consider the following aspects when deciding which site is the best for you:

Minimum Deposit: Make sure you choose a bonus that suits your budget. We have a range of low deposit offers available from a £1 deposit up to £20. We also have an extensive list of free spins with no deposit required.
Banking Options: All British casinos accept deposits by debit card, but many players prefer the added security of using an eWallet at a PayPal Casino, or the ease of Pay by Mobile casinos.
Wagering Requirements: The amount of times you need to playthrough your bonus will dictate the amount of time you need to play at the site. If you want to withdraw your winnings fast then lookout for free spins no-wagering bonuses.
Software Providers: There is a wide range of game developers creating online slots and live casino games. Most British sites have all the top slot games from major providers covered, like Microgaming and NetEnt, but check out the selection if you want to play games from smaller studios like Yggdrasil or No Limit City.
Live Casino Games: we love playing online Roulette and Blackjack with a real dealer, but these games are often excluded from standard casino welcome bonuses.

❓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 licence don’t accept UK customers.

Is it safe to gamble online?

Yes, online gambling is safe. Gambling sites are overseen and regulated by the UK Gambling Commission, ensuring the sites stick to the strict standards they’ve set. Even the game companies (Microgaming, Netent and others) that create all those fun slots are regulated. Therefore, you can rest assured that the games are fair.

Will my winnings be taxed?

Online gambling wins are not taxed in the UK at all. No matter how much you win or what game you have played – there is no tax involved.

Can I trust BonusFinder reviews?

Yes. We review various online gaming platforms and only recommend those that meet our strict standards. We only promote licensed and legal online gambling platforms operating in the United Kingdom.

How do you verify your bonuses?

We are affiliated with over top 100 online casinos in the UK and we receive our bonuses directly from these brands; our bonus links and codes are automatically updated. This ensures that the bonuses on our site are always valid and up to date.

Our BonusFinder team manually updates the content on our review pages, which means you might occasionally encounter discrepancies between the information in the content and the bonus link – our team is likely still in the process of updating the review! In these cases, the information at the top of the page is usually the most accurate.

If you notice any errors in our content, don’t hesitate to reach out to us through our email form!

How can I stay updated on new casino bonuses?

The easiest way is to subscribe to our email newsletter! That way, you’ll get notified about the latest bonuses – no need to browse through our site manually.

Does BonusFinder offer customer support if I have issues with a bonus?

If you have any issues with a bonus, please reach out to the customer support team of the online casino. While BonusFinder rates and reviews bonuses, we are unable to assist with issues that occur on the gambling site itself.
