How We Rate & Compare UK Online Casino Bonuses

We don’t just recommend any UK online casino that happens to have a generous welcome bonus. We have a comprehensive review process where we test all aspects of a casino and specifically focus on the following aspects:

Licensing + Safety

UK Gambling Commission

We only recommend UK-regulated gambling websites. It is illegal for online casinos to operate in the UK without a UKGC license, and these offshore casinos often have rigged games, fake bonuses and refuse to pay out winnings. When reviewing a UK online casino, we check that their license is real and up to date. Then we study player reviews and make sure the casino hasn’t been involved in any scandals.

Games

Various Casino Games

No one wants to be stuck playing slots from 2005 and a boring online roulette game. We look for online casino casinos that have 1000 + games, including the latest slots, poker, blackjack, baccarat and live dealer games. All of the casinos we recommend have free games from leading developers, including NetEnt, Microgaming, Evolution Gaming Play’n Go and Pragmatic Play. Some games that you have to try include Lightning Roulette by Evolution Gaming and Thunderstruck II by Microgaming.

Customer Support

Dodgy UK online casinos try to cut costs at every opportunity, and that means having as few customer support staff. We only recommend UK casinos that have 24/7 live chat where you can instantly talk to a real person!

Payment Methods

Payment Methods

Before giving an online casino our stamp of approval, we look at the number of payment methods available, processing times, min/max limits and fees. We look for casinos that have a wide range of secure and free payment methods that offer instant processing times.

Casino Bonuses in the UK

Casino bonuses in the UK come in all shapes and sizes. Here are just some of the bonuses on offer at UK online casinos:

No Deposit Bonus

As the name implies, a no-deposit bonus is any promo you receive when you register at an online casino without making a deposit. With these promos, you can win real money at an online casino without spending your own cash. No deposit bonuses typically come in two forms, free spins and bonus cash. A typical no-deposit bonus might be 50 free spins on Starburst slot when you sign up. When looking for no deposit bonuses, make sure they have low wagering requirements (less than 30x) and a high or no max bonus win cap.

Welcome Bonus

A casino welcome bonus is a promotion you get when you make your first deposit. Welcome bonuses are the most popular UK casino bonus because betting sites are willing to give away lots of free play in an effort to attract new casino players. Welcome bonuses usually feature a deposit match where you receive bonus cash based on the size of your deposit and or free spins. For example, if you claim a 100% deposit match and deposit £200, you will receive £400 in total.

Reload Bonus

A reload bonus offer is very similar to a casino welcome bonus but is applied to any deposit you make after your first one. Reload bonuses come in the form of free spins and deposit match deals. They are usually smaller than welcome bonuses, but 50% deposit match reload deals are still common.

Free Spins

Free spins allow you to play real money casino slots for free. Each free spin gives you one bet on a slot machine, and they are typically worth the min bet limit for a specific slot. It is common to receive 50 + free spins as part of your welcome bonus. The money you win from free spins is typically paid in the form of bonus cash.

Bonus Cash

Bonus cash allows you to play real money casino games with the betting site’s own money. Unlike bonus spins which can only be used for slots, bonus cash can be used for all casino games, including table games. You can receive bonus cash when you sign up or make a deposit. Unfortunately, you can’t withdraw only bonus funds, you first need to complete the bonus wagering requirement.

Cashback

Cashback is a unique type of bonus offer where the casino will refund a percentage of your losses. For example, let’s say you lose £300 and claim a 10% cashback deal. The casino will send £30 back to your casino account. Cashback is a common bonus for live dealer casino games and is either paid out daily or weekly. The cash you receive can either be bonus cash and come with a wagering requirement or be withdrawable cash.

Loyalty Program

To keep existing casino players happy, UK betting sites often have VIP and loyalty programs. How they usually work is you earn points for every £1 bet, and then you can convert these points into cash or prizes. VIP hosts will also offer custom bonuses to high rollers, including free spins and bonus cash.

How to Get a Casino Bonus at the UK’s Top Online Casino Sites?

Dream Vegas Sign Up

UK online casinos have designed their sign-up process so you can fully register and claim your welcome offer in just a few minutes. To claim your UK casino bonus, all you need to do is:

  1. Select any online casino from our list and go to their site via our link to get an exclusive bonus
  2. Tap the sign-up button and complete the registration form by typing in your full name, mobile number, address, date of birth, currency and email
  3. If required, enter the bonus promo code or simply accept the bonus
  4. Tap the deposit button, enter at least the minimum required amount to claim a bonus (usually, the minimum requirement deposit to claim a bonus is between £10 and £20) and enter your payment details
  5. Verify your age and identity by uploading your ID and proof of address

After your account is fully set up and verified, the bonus will be automatically credited to your account. You then can’t use your bonus cash to free spins to play the latest slots and table games!

Bonus Codes

A bonus code is a unique combination of letters and or numbers which, when entered, unlocks a casino bonus. You typically enter bonus codes when signing up or making a deposit. The casino will have a specific section, simply copy and paste the promo code and hit the apply button. Thanks to UK casino bonus codes, you can instantly access exclusive casino promotions and win real cash using the casino’s own bankroll.

Not all bonuses require a promo code. So before you attempt to claim casino bonuses, double-check the terms and conditions and follow the steps required. To save you precious time, we have provided the latest promo codes to unlock the best UK casino bonuses.

Wagering Requirements & Bonus Restrictions

While UK online casino bonuses do have value and offer free play, they aren’t free money. Before you can cash out your bonus, you have to complete the wagering requirement, which states the number of times you need to bet your bonus. For example, if you claim a £100 bonus with a 20x wagering requirement, you need to make bets totalling £2,000 before you can cash out. Typical wagering requirements range from 10x all the way up to 50x.

UK casino bonuses also come with other restrictions, including max win caps which limit the amount you can win when playing with a bonus. Certain games are also usually restricted when playing with a bonus offer, including progressive jackpots and high RTP games like blackjack and baccarat.

You also need to look out for expiry dates. If you haven’t completed the bonus’s wagering requirement by the time the promo expires, then the entire bonus and all winnings will be removed from your casino account. Sometimes UK casino bonuses can expire in as little as a few days, so make sure you have enough time to play before you claim a promo.

Tips for Using UK Online Casino Bonuses

If you think you are just going to claim a juicy casino welcome bonus and then laugh all the way to the bank, you have another thing coming. To outsmart the casinos, you need to come up with a strategy. Here are a few tips which will boost your odds of generating a profit:

  • Avoid bonuses with high wagering requirements – If the wagering requirement is too high, you have no chance of ever cashing the bonus out, and it essentially becomes worthless. You should look for bonuses with sub-30x wagering requirements, sometimes, you can find bonuses with 10x playthrough requirements.
  • Deposit the minimum to get the free spins bonus – Often, online casinos will offer you a bunch of bonus spins when you deposit. The amount of free spins doesn’t change, irrespective of the amount you deposit. So if an online casino is giving away 100 bonus spins when you deposit at least £10, then just top up your account with £10, that way, you can protect your downside while maximizing your upside.
  • Play high-volatility slot games – High-volatility casino slots don’t pay out often, but when they do, they pay out big! These slots also have sizable jackpots. When playing with the casino’s cash, you may as well take some free risk and try to hit a big win. Some top high-volatility slot games include Pirates Pub, Medusa Megaways and Big Bass Bonanza.
  • Find high RTP games – Unfortunately, many online casinos ban high RTP games like blackjack or baccarat or jack up the wagering requirement. However, you can usually play high RTP slots and enjoy the standard wagering requirement. High RTP slots to look out for include Blood Suckers (98%), Starmania (97.87%), White Rabbit (97.72%) and Medusa Megaways (97.63%).
  • Try the Martingale betting strategy – How it works is you pick a bet type with as close to 50/50 odds as possible such as red/black in roulette or banker/player in baccarat. Then you place a bet. If you win, you keep betting the same amount, but if you lose, you double your bet. You keep doubling your bet until you finally win. While this method won’t work in the long run, if you start betting with just $1, you have to get pretty unlucky to lose!

Background on Online Casinos in the UK

Brits have been gambling for hundreds of years on virtually everything from dice to cards to archery to cricket and, of course, football. And despite Henry VIII banning virtually all forms of gambling back in 1541, it didn’t stop even the King himself from betting on the odd sporting event.

Even though gambling remained legal in the UK, bookmakers and gambling houses thrived in the 1600 and 1700s. It wasn’t until 1928 that Brits could finally legally bet on horse racing, and then a few years later, in 1934, they also had the privilege of gambling on greyhounds.

Football betting had been popular for a long time in the UK before football betting pools were finally regulated and taxed under the Betting and Lotteries Act 1934. It took until 1960 that private casinos and casino games were finally legalized in the UK under the Betting and Gaming Act 1960.

The UK fully regulated online gambling via the Gambling Act 2005, which was built upon Betting and Gaming Act 1960. Online casino sites and bookmakers are now fully legal in the UK as long as they are licensed under the UKGC and follow all of the regulator’s stipulations; these include strict responsible gambling rules, KYC protocols, accurately represented bonuses and fair games.

The UK online gambling market is considered one of the most successful in the world. It is estimated there are 2,000 operators, and the UK market is responsible for 30% of total online gaming revenue in Europe.
