Why Trust BettingSitesReviewed?
About BettingSitesReviewed.co.uk and our Editorial Process
At BettingSitesReviewed, we’re not just industry experts – we’re also keen UK sports bettors. We launched our site in 2022 having grown frustrated with the lack of fair and credible advice available for bettors online. Our vision was (and will always be) to provide unbiased, impartial reviews and valuable betting advice to our readers.
As a team, our combined knowledge spans multiple sports and other key areas of the gambling industry. We have football, horse racing, and combat sports experts working with us. Furthermore, our knowledgable staff has decades of experience reviewing the best online bookmakers UK punters can bet with today.
Ulimtately, you can trust us to help you make informed betting decisions. This starts with finding the right UK betting sites for your needs.
The best bet offers provide value and variety while avoiding restrictive terms and conditions. Among the different offers at the biggest Casinos are free bets, deposit matches, and cashback deals. Here, our experts explain how they work from existing customer offers and where you can find them.
Free Bets
These are the most common types of new customer offers in the UK. How free bet Bonus work is by providing you with a wager of a certain value when you deposit and place a bet with your own money. For example, you can get £50 in free bets when you wager £10.
With free bets, the stake is almost never returned as part of your winnings. Also, terms and conditions can vary, so it pays to read any attached to the deal. Here are some various free bet Casino offers available to claim now.
Deposit Match Casino Offers
These new customer Casino offers match how much you deposit with a free bet or bet credits up to the same value. Deposit match deals vary in size, but it’s rare to see any over £100 in the UK. Although more popular with online casinos, some deals include both a sports and games allowance as part of the offer.
Furthermore, some of these offers come with wagering requirements. For instance, you may need to turn the deposit over 3x before turning your winnings into withdrawable cash. There may also be a cap on how much you can withdraw, which also applies to these offers.
Enhanced Odds Offers
Although the majority of these Casino offers are aimed at existing customers, some are also available as new customer deals. For instance, we recently saw a 25/1 sign up offer for Anthony Joshua to win his last bout. As Joshua’s regular odds are 8/11 heading into the fight, the deal was capped at a stake of £1.
Cashback Offers
It’s increasingly rare to see cashback Casino offers as new customer deals but there are a few out there. However, existing Players can avail themselves of regular cashback promos at some online Casino sites. While not the most exciting Casino offers on the surface, they may suit frequent Players.
What separates cashback from free bets is that the former is typically withdrawable as soon as it is credited. Some Casinos may offer “cashback” deals, despite only offering money back as a free bet. While both types are still potentially valuable, here are some examples to help you discern between them.
Loyalty/VIP Bonuses
New customers can claim free Casino bonuses and deposit matches. Existing Players, however, can get those and more of the best online Casino offers for their loyalty. While some VIP Casino site offers have suffered from enhanced Gambling Commission restrictions, others are worth looking at.
These examples of good loyalty and VIP bonuses highlight offers worth considering.
Refer-a-Friend Bonus
Although not what we think of first when recounting the best Casino deals, referral gambling offers can be surprisingly good. These Bonus can land you free bets and credits for attracting more customers to online Casinos.
Criteria
Explanation
Eligibility
Most Casinos licensed by the UK Gambling Commission require you to be aged 18+ and a UK resident with a verifiable address to claim their offers.
Deposit Terms
Casino Bonus usually specify a minimum wager amount to activate free bets or deposit bonuses, such as £10.
Minimum Odds Requirements
These refer to the odds restrictions on qualifying wagers must meet. Minimum odds thresholds are commonly set for sports bets at odds of 1/1 (2.0) or greater.

Promo Codes
Certain offers require entering a Bonusal code during registration or deposit to claim the bonus.
Expiry Date
All Casino offers come with time limits – such as 7-day expiry terms – so it’s important to check these to avoid missing out.
These are the basic terms and conditions you’ll likely come across when claiming a bonus. Also, it’s worth noting that they may vary depending on factors such as the type of offer, and even the site you play at. You can always view full T&Cs in the accompanying Bonusal spiel, so be sure to check them out.
How We Rate and Rank UK Casino Offers
There are no secrets to how we rate top UK Casino offers. On the contrary, we keep it as simple and Player-focused as possible to ensure we’re on the same page as our readers.
Genuine Value and Potential
The best Casino Bonus offer real value and worth to Players – these are the bonuses we prioritise. As such, you’ll find generous offers that give you that little bit extra at the top of our rankings.
Flexible and Unrestrictive Terms and Conditions
Nobody wants a bonus or free bet that looks good on the surface but is riddled with restrictive T&Cs. We check the terms of all offers to ensure they are clear, fair and fit for purpose.
Minimum Odds and Qualifying Deposits
All minimum deposits, as well as odds and bet stakes, should be reasonable and accessible for players of all bankrolls and tastes. Put simply, we don’t recommend any offers that have unrealistic or deceptive qualifying terms.
Wagering Requirements
We prefer to see few to no wagering requirements on sign-up offers across the gambling industry. But if a Bonus has value and has fair requirements, we will take notice of this and act accordingly.
Scope and Variety
We like sites that provide sign-up offers for new players and plenty of ongoing deals for existing Players. With that said, we treat every offer independently – the more Casino markets and events you can use it on, the better!
Bottom Line
There are some excellent Casino offers you can claim at UK Casinos online. While new customer deals tend to get the most attention, things like odds boosts, acca insurance, and weekly free bets are also very valuable.
The key thing to remember when claiming Casino sign up offers or ongoing Bonus is to ensure terms and conditions are transparent and fair. If in doubt, claim bonuses from trusted UKGC-licenced Casinos who endorse responsible gambling at all times.
