One of the best things about online gambling is the range of promotions available for new and existing customers. Whether you’re looking for a bag of free spins to use on the latest slots or a free bet token to have a flutter on an upcoming football match, there’s plenty on the market right now.

While the first thing you’ll often notice when browsing different online casinos is their welcome offers, there’s also plenty available once your initial bonus has dried up. On this page, we’ll be focusing on everything you need to know about the best gambling promotions for existing customers. After all, a welcome offer is just the start of your experience — ensuring that there are plenty of bonuses up for grabs going forward is arguably one of the most important aspects of choosing an online casino.

Top Casino Promotions

Which Gambling Promotions Are Available?

Before signing up to a new casino or sportsbook, it’s well worth familiarising yourself with some of the types of gambling promotions available once you’re registered. Let’s have a look at some of the most common.

Login Bonuses

Some casino sites offer players rewards just for logging in — it can’t get much simpler than that! These bonuses may also be aimed at inactive players who haven’t logged in for a while. You’ll usually be able to pick up a modest prize like 5 free spins, or some comp points that can be exchanged for cash once you’ve collected enough.

Freeplay Bonuses

While some bonuses require players to make a deposit or place a bet to receive a reward, some of the best gambling promotions for existing players are completely free. A casino may dish out rewards like free spins for selected slot games or a free bet offer for sports markets to keep players interested. Additionally, many casino tournaments are also free to enter. In a tournament, you’ll pick up points when you play slots and advance up the leaderboard the more you win. If you finish in the prize places at the end of the tournament period, you could bag a slice of the prize pot.

VIP Rewards

Many online casinos give players the chance to rank up a series of VIP levels and pick up rewards along the way. In most cases, you’ll start collecting loyalty points straight off the bat just for playing your favourite slots and casino games. The rewards generally become more lucrative as you rank up, and can include anything from free spins, to higher deposit limits, to exclusive trips and holidays. At some casinos like Casushi and Peachy Games, the rewards scheme works more like a shop, where you can directly exchange loyalty points for free spins on a slot game of your choosing.


Cashback is another popular gambling promotion for existing customers. Also known as a rebate bonus, cashback allows you to claim back a certain percentage of your losses as either bonus credit or withdrawable cash. It can work on a daily, weekly, or monthly basis — at All British Casino, for example, players can reclaim 10% of lost deposits every 24 hours as cold hard cash.

Weekly Deposit Bonuses

Many casinos offer weekly promotions on a particular day of the week — these can take various forms, but one of the most popular is a deposit bonus. If you deposit a certain amount on a particular day, the casino will give your funds a helpful boost or offer an additional prize. At Mansion Casino, for example, players depositing £20 as part of the Wild Wednesdays promotion will be entered into a £20 weekly prize draw, which can be spent on the site’s range of slot games.

Free Bets Clubs

Readily available from top bookies like 888sport and Betway, free bet clubs are an easy way to net yourself some regular free bets. To participate in these popular betting offers and get your freebie, you’ll usually need to opt-in and wager a certain amount on sports. Free bet clubs often run on a weekly basis and may require your qualifying wagers to be certain types of bets, such as accas. You may also need to place your qualifying bets on specific sports betting markets, such as the Premier League or the NFL, and at minimum odds too. The specifics of free bet clubs and the value of the free bets on offer vary between sites, which makes it worth shopping around to find the best deals. 

How To Claim a Gambling Promotion As An Existing Customer

Here we’ll break down how to claim an online gambling promotion. The process can vary a little more when you’re an existing player, compared to claiming an initial sign-up offer, but you can follow the general steps below to get started.

  • Head to the promotions page – every site’s list of casino bonuses can be found on its promotions page. You’ll see the welcome bonus for new customers, which you may have already claimed, followed by the range of promotions for current players.
  • Browse the available offers – check out the options and consider what appeals to you most. Are you keen to have a weekly promotion to look forward to, or would you rather hold out for a one-off freeplay bonus? 
  • Click through and read the instructions – each online gambling promotion will offer instructions on how to claim. You might need to deposit a certain amount to unlock rewards, or it might just be a case of finding out how and where to claim your daily cashback.
  • Read the terms and conditions – always be sure to read the T&Cs before claiming a gambling promotion so you know what to expect. Rewards such as free spins may be subject to wagering requirements, while bonus cash may be withdrawable or for use on games only.
  • Enjoy your bonus! – whether it’s free spins for slot games, bonus credit for the roulette table, or a free bet on the upcoming boxing bout, be sure to have fun with it.

Top Sites Offering The Best Gambling Promotions

UK casino players have a huge number of sites to choose from, so it’s well worth shopping around to find the right operator. Here at GamblingDeals, that’s where we come in — check out some of the best sites for gambling promotions below.

NameBonusClaim BonusReviewTerms and conditionsInformation

Welcome Bonus up to £100 + 50 Bonus Spins

Claim Bonus

Swedish operator LeoVegas is one of the best sites in the business for gambling promotions. Once you’ve played through the free spins welcome offer, there are tons of additional bonuses to get your paws on. Several of the promos are centred on completing objectives on specific games — with Live Lightning Mondays you can pick up free casino chips for Evolution’s Live Lightning Roulette. The Blackjack Hunters deal, meanwhile, runs on Tuesdays, Wednesdays, and Thursdays and gives you the chance to bag a £10 free game if you collect 3 blackjacks.

18+, T&Cs apply. New reg only. Opt in & deposit £10, £25 or £50 within 7 days & further 7 days to wager cash stakes 35x to unlock reward (£50 on 2 deposits). 3 day exp. Wagering/game contributions vary. 25 wager-free spins x10p to added to Big Bass Splash with each qualifying deposit, 3 day expiry.

100% Up To £100 + 10% Cashback

Claim Bonus

With its red phone boxes, letterboxes, and a logo reminiscent of English rock icons The Who and the RAF roundel, All British Casino certainly hits its intended theme on the head. As for its promotions, existing players enjoy 10% cashback on all their lost deposits on the site — it’s withdrawable cash that’s yours to keep with no strings attached. What’s more, its Marvellous Midweeks promotion changes each week and gives you the chance to bag a range of prizes, such as bonus spins when you deposit £10 or more.

Welcome bonus for new players only. Maximum bonus is 100% up to £100. No max cash out. Wagering is 35x bonus. Maximum bet while playing with a bonus is £5. Max cashout £100 if never deposited, no mac once deposited. Bonus excluded for players that deposit with Skrill or Neteller. Full T&Cs apply.

What You Need To Think About Before Accepting An Online Gambling Promotion

As we’ve touched on throughout, there are terms and conditions associated with every bonus deal. The small print can be a little confusing at some sites, so it’s good to familiarise yourself with the key terms before opting in to avoid any disappointment further down the road. For some players and punters, the best gambling promotions are the ones with the most player-friendly terms rather than those with the largest bonuses. With that in mind, let’s check out some of the most common T&Cs you’ll likely come across.

Wagering Requirements

Wagering requirements are most commonly attached to casino welcome offers, but they do pop up in promotions for existing customers too. When claiming bonus credit or free spins as part of a deal, players will often need to wager the bonus amount or any free spins winnings a certain number of times before they can convert these funds to cash. For example, let’s say you bag £20 in bonus funds and there’s a 20x wagering requirement attached. Here, your casino bonus funds will remain non-withdrawable until you have wagered at least £400 (£20 x 20) on the site. Wagering requirements very rarely apply to sports bets, though you will have to use any free bet credits as intended and can’t simply withdraw them as cash. 

Game Weightings 

When it comes to completing wagering requirements, it’s important to realise that some of your bets may not contribute in full. For table games like blackjack and roulette, the contribution to wagering requirements can sit between 5% and 20%. This means that for every £10 you wager, only 50p to £2 comes off bonus rollover requirements. To speed things up, most casino players stick to playing slots when fulfilling playthrough demands. These games generally contribute fully, though there are occasional exceptions for high RTP slots like NetEnt’s Mega Joker and Playtech’s Ugga Bugga, when the contribution may be reduced to 90-95%. The T&Cs for individual bonus offers will tell you if game weightings apply, so remember to check them out. 

Time Limits

Time limits apply to online gambling promotions in a few different ways. Many existing customer bonuses pop up on a set day each week, and you’ll often need to qualify by a certain day — which might simply consist of opting in, or depositing or betting a certain amount. Once you’ve claimed a bonus, you’ll only have a certain amount of time to use it. Free spins, for example, often need to be used with 24-72 hours of receipt. For bonus funds, you might get anything between three and 30 days. And if there are wagering requirements involved, they may need to be completed within these time limits too, otherwise the bonus amount and any resulting winnings will be forfeited.

Game Restrictions

While some bonuses can be used on any game at a casino site, many gambling promotions come with game restrictions. The best example of this perhaps comes courtesy of free spins welcome bonuses at online casinos, where the free spins will almost always be for a specific top slot like Starburst, Book of Dead or Fluffy Favourites. However, game restrictions can also apply to gambling promotions for existing customers. In practice, this could mean that a chunk of free spins you pick up in a weekly promotion may only be eligible for selected slot games. While casinos tend to include the most popular slots in bonus spins offers, it’s worth checking them out beforehand to see if they’re your cup of tea. 

Bets on Certain Markets

As for sports betting bonuses, you’ll find a lot of enhanced odds, acca boosts, and free bets will be offered for particularly big events, such as football cup finals, highly anticipated UFC fights, and anything else that draws a large audience. You might also find that any free bet clubs you join require you to place your qualifying wagers on certain sports betting markets. At 888sport, for example, you can place £20 worth of Bet Builder bets to earn a free £5 bet each week, but these bets must be on football, NBA, NHL and MLB games. That said, there are usually plenty of offers up for grabs across a wide range of markets, so be sure to look out for betting offers on sports that interest you.

Payment Method Restrictions

The terms and conditions for online gambling promotions often exclude customers from using certain payment methods to qualify for offers. These payment method restrictions can apply to bonus offers available from both online casinos and online sportsbooks. The most common payment methods to be excluded from promos are e-wallets like Neteller, Skrill and MuchBetter, along with deposit-only banking options like Paysafecard and Pay by Mobile services like Boku. You’ll usually be just fine to make your qualifying deposit using a major debit card or via a Trustly instant bank transfer, though, as ever, it’s wise to check the bonus terms to confirm this is the case. 

Winnings Caps

Some gambling sites place restrictions on how much you can win from bonuses. These winnings caps can apply to individual bonuses, as well as over the lifetime of your account. At 777 Cherry, for example, players can usually only win a max of £8 per 10 free spins received. This Jumpman Gaming casino also places limits on how much you can cash out from bonus funds during your time as a customer. Basically, you will only be able to withdraw bonus winnings equal to the value of your real money deposits on the site, up to a maximum of £250. Other online casinos can be a bit more generous, so it’s worth comparing the small print for each site you like. Winnings caps also occasionally apply to sports betting bonus offers.

Gambling Promotions vs Welcome Bonus

The gambling industry in Great Britain is awash with promotions for players and punters alike. At a minimum, most online gambling sites will give you some kind of sweetener when you sign up for a new account. Whether that’s bonus spins at an online casino or free bets at a betting site, a new customer offer can help you get off to a great start at a new gambling site, allowing you to get to grips with how a site works and what it has to offer before you put too much of your own money on the line.

As fun as they are, welcome bonuses are a one-time deal, to be claimed and enjoyed by new UK customers on a single occasion. Over time, it’s the gambling promotions for returning customers that tend to serve up the most value and enjoyment. At online casinos, these existing player promotions might involve treats like free spins and cashback, while sportsbooks run promos like bet clubs and odds boosts offers. At Gambling Deals, we also feature sites that offer real money gaming and sports betting under the same roof, so there’s nothing to stop you from enjoying both types of promotion. 

Existing Customer Promotions

Like welcome bonuses, existing customer offers might be one-time affairs — perhaps a few free spins for a new online slot game, or a free £1 bet on a popular sporting event like the World Cup. Some offers, however, are available to be enjoyed again and again. 

The terms and conditions for gambling promotions for existing players are usually a bit less restrictive than those attached to the welcome bonus offers aimed at newcomers. For example, you’ll often see lower wagering requirements for casino bonuses as a loyal player than you would as a newbie. It’s always worth giving the T&Cs the onceover though, as it’s likely that other factors like game restrictions and bonus expiry times will still apply.

Using a Gambling Promotion for Casino Games

Casino promotions come in a variety of flavours, so you’re sure to find one to suit, especially if you stick to the top online casinos recommended here at Gambling Deals. The best online casino sites hit the spot with reload offers, free spins, cashback deals, loyalty programmes, sharepots and straight-up cash rewards. Below you’ll find a rundown of some of the different types of games you can play when taking part in these promotions.


Slots make up the bulk of the game collections at most online casinos, and it’s not unusual for the best sites to feature thousands of titles from top developers like NetEnt, Playtech and Microgaming. Slots offers are also plentiful at online casinos and slots sites, so you should have no problem picking up free spins from the promotions page. While welcome bonus offers are usually for well-known slots like Starburst and Book of Dead, slots promos for existing players will often give you the chance to try the latest games.

New accounts only. Min. £10 deposit, debit card and PayPal only. 50x wagering, game contributions vary, max. stake applies. 7 day expiry. See full terms.

Table Games

For fans of classic table games like blackjack, roulette and baccarat, most online casinos will have a range of RNG games you’ll want to add to your favourites list. You can usually wager any bonus funds you get from a gambling promotion on classic casino games, but if wagering requirements are involved, you should check the offer’s terms and conditions for a games weighting table. Even at the best online casinos, wagers on table games may contribute just 10% to the overall playthrough demands. 

Live Dealer Games

If you crave the excitement of a brick-and-mortar casino, you can find it on your computer, mobile phone or tablet when you play live dealer games at online casinos. These live games are hosted by leading software providers like Evolution and Pragmatic Play, so an authentic experience is on the cards. Casinos often run promos aimed at encouraging customers to try live dealer games, so be sure to stay up to speed with updates to the promos tab. You might just find a live casino bonus for live blackjack or a live casino game show.

Using a Gambling Promotion for Sports Betting

At top online sports betting websites, you’ll find promos like weekly bet clubs and bet and get offers on everything from the Premier League to the PGA. And just like at online casinos, you can also enjoy reload bonuses, cashback offers and loyalty schemes. There are plenty of ways to put a sportsbook bonus to good use. Below you’ll find a quick overview of the different types of betting options you’ll find available.

Standard Sports Bets 

A standard pre-event sports bet is one of the simplest ways to wager on an online sports betting website, so it’s hardly surprising that punters love to add them to their bet slip. Weekly bet clubs are a great way to get involved in pre-match betting and earn a bonus in the process. Most of these clubs require you to bet a certain amount through the week to earn a free bet bonus, but the specifics do vary. 

NameBonusClaim BonusReviewTerms and conditionsInformation

In-Play Betting

Pre-match betting may be simple and straightforward, but in-play betting livens things up a bit and adds an extra dimension to online sports betting. It’s in the live betting markets that you’ll find exciting short-lived wagers, such as Emma Raducanu to win her next point or Dominic Calvert-Lewin to score for Everton in injury time. Many online sportsbooks run offers whereby you can wager a certain amount on pre-match markets to get a free in-play bet. 

NameBonusClaim BonusReviewTerms and conditionsInformation

Unibet offers sports bettors a free £10 in-play bet every week. To qualify for the freebie, you’ll need to place five or more £10 in-play bets at odds of 2.0 or greater. Wagers can be on football, basketball, cricket, tennis or darts.

Acca Promotions

Acca promotions are really popular at online sports betting sites, so if you fancy your chances of landing a big payout courtesy of combined betting odds, they’re worth looking out for. There are a couple of different types of acca offers out there, though one of the most common is acca insurance, which will return your stake — usually as a free bet but sometimes as cash — if one leg lets you down. You can also find acca promotions that offer a boost to your winnings: the more legs on your winning acca, the bigger the boost.

How We Find the Best Gambling Promotions

Here at Gambling Deals, we’re always looking out for the best gambling promotions for our visitors. To find the top deals, we put each promo through its paces, determining what goodies are up for grabs, how to get your hands on the rewards and which strings are inevitably attached. Below you’ll find a list of some of the things we consider when we review gambling promotions.

Eligible Games or Betting Markets

Gambling site promos are often targeted at certain activities. At online casinos, for example, it’s common for promotional offers to be for a specific game or a selection of games from the same developer — as is the case with the widely available Pragmatic Play Drops & Wins tournaments. At online sportsbooks, meanwhile, you’ll often come across promos where you need to wager on specific sporting events in order to claim a free bet bonus, which may also be for a certain betting market. Our gambling promotion reviews tell you what to expect. 

Promotion Value 

Another factor we appraise when we review a gambling promotion is the overall value of the offer. This goes beyond the size of an offer — some promos can seem extremely generous on face value but if high wagering requirements make it all but impossible to cash out any winnings, that value is put into serious doubt. We assess the time and money you’ll need to invest into a promotional offer — against what you might get in the way of a payout in return — and let you know if an offer is worth a shot. 

Terms & Conditions

Understanding the terms and conditions for a gambling promotion is crucial if you want to be in with a chance of cashing out. Players have sometimes been left disappointed because they’ve used an ineligible payment method and accidentally ruled themselves out of an offer. We scrutinise the small print looking for payment method exclusions, as well as details like minimum deposits, bonus expiry times and bonus wagering requirements. We’ll report back on anything important you need to know. 

Deposit Requirement 

The minimum deposit required to participate in promos is another consideration. This varies between offers but often sits around the £10 mark. It’s also possible to find no deposit offers, such as the £5 free bet available at CopyBet and the £5 casino bonus at Monster Casino. However, these offers tend to be for new customers and T&Cs can be stricter than normal. The CopyBet offer, for example, has a £500 winnings cap and the Monster Casino promo comes with a 100x wagering requirement. It’s not our job to withhold these factors from you; our reviews tell you what’s what. 

Payment Exclusions

Payment method exclusions are a bit more common with new customer offers than existing player promotions. Nonetheless, if a gambling site promotion requires a deposit, we always check if any payment options are off limits. The most commonly excluded payment methods include deposit-only options like Paysafecard and Pay by Phone services such as Boku and Payforit, though some online gambling site promotions also exclude e-wallet deposits from Neteller, Skrill, and less frequently, PayPal. 

Best Gambling Promotion Summary

It’s clear to see casino players and sports bettors are spoilt for choice when it comes to online gambling promotions. The vast majority of operators offer a variety of bonuses for existing customers, so the power is in your hands to opt in to the ones that appeal to your interests.

What’s also important to mention, however, is that gambling promotions are completely optional — from the initial welcome bonus, to weekly bonuses, to VIP rewards, there’s no obligation to get involved. It’s important to think of promotions primarily as a means to try out new or favourite games for a cut price, rather than a way to make money. 

If you’ve got an idea of which online gambling promotions you’re interested in or if you’d like to browse a bit more, check out our comparison lists for more info. When you find a site you like the look of, click through to sign up and get started with hundreds of games, sports markets, and top-class promotions.


  • Which gambling sites are offering free bets?

    Hundreds of gambling sites offer free bets for sports fans, across a range of different events and markets. You’re bound to find some good deals at the most popular bookmakers — check out our reviews of Ladbrokes, Unibet, William Hill, Coral, BetVictor and Betfair, to name a few.

  • To a large extent, this comes down to personal preference. Some punters are keen to bag the largest free bets and free spins bundles on the market, while others are more concerned with finding deals with low or no wagering requirements and other player-friendly terms.

  • Yes. Participating in online gambling promotions is perfectly safe, assuming you stick to casinos and sports betting sites that are licensed by the UK’s Gambling Commission. Licensed sites in the UK are tightly regulated to ensure that punters and players can look forward to online gambling experiences that are as safe and fair as they are fun. 

  • You can feel confident that all the gambling sites featured on Gambling Deals have a current licence from the Gambling Commission. You’ll see their logo in the footer of the homepage of a legitimate casino or sports betting site, but it’s wise to confirm. You can do this by heading to the UKGC website and searching for the name of the gambling site.

  • Sometimes. The use of bonus codes is quite common for welcome offers but less so for existing customer promotions. These deals are likely to require you to opt-in from the promo page, before making a qualifying deposit or when opening an eligible game. Top brands like Coral and Paddy Power may also send gambling marketing offers direct to your inbox. The T&Cs will include the details you need to claim an offer, so be sure to read them in full.

  • A gambling bonus is a reward that you can claim at online gambling sites, such as online casinos, football betting sites and real money bingo sites. Gambling bonuses are available to both new and existing players and often come with terms and conditions attached. These T&Cs may include things like wagering requirements, eligible deposit methods and winnings caps. 

  • That depends on what you think of as the best gambling promos. New online casinos can be generous to new players, perhaps offering a welcome package that consists of free spins and a matched deposit bonus combined. However, longer-standing sites may offer a better selection of deals for existing customers. Browse our online casino reviews to find your best fit. 

  • A free bets club is a type of promo run by online sports betting sites. Free bets clubs work as a bet and get-type deal, requiring punters to wager a certain amount over a set period of time to earn a free sports bet. For example, you might need to bet £20 on sports between Thursday and Sunday to earn a free £5 bet on the following Monday. You will usually need to opt-in to join bet clubs, and since various T&Cs apply, you should always remember to give the promo terms the onceover before placing your bets.
