some have high wagering requirements, which means you likely won't keep much profit from your welcome bonus. It is our duty to inform you of such caveats, so you always make an educated choice!
| Bonus Type | Typical Value | Customer Risk | Wagering Requirement | Real Money Potential |
|---|---|---|---|---|
| No Deposit Bonus | $/€/£5 - $/€/£20 | None (no deposit) | Very High (15x-50x) | Low |
| Small Deposit Match | 100% up to $/€/£50 | Low (small deposit) | Moderate (5x-10x) | Medium |
| Large Deposit Match | 100% up to $/€/£200 | High (large deposit) | Standard (5x-10x) | High |
Existing customer bonuses are just as important in our quest to provide you with the most value.
Many mid-tier betting sites stop engaging the player after they've claimed the sign-up offer. What makes a bookie stand out are the various bonuses and promotions you can claim time after time, weeks down the road.
| Bookmaker | Sign-Up Offer | Max Bonus Value |
|---|---|---|
| Bet365 | Bet Credits up to $/€/£30 | $/€/£30 |
| William Hill | Bet $/€/£10 Get $/€/£30 in Free Bets | $/€/£30 |
| Betfair | Money Back as Cash up to $/€/£20 | $/€/£20 |
| Unibet | Money Back up to $/€/£40 if First Bet Loses | $/€/£40 |
So we make sure to find these valuable offers that you can claim even if you're already a registered customer.
Whether you found a new bookie that you’d love to see us add, or you have a burning question for our team of experts, we want to know all about it. This is why we constantly check on our email, so you can reach out at any point of your betting journey. Straight talk – if a bookmaker sucks or has poor features, we'll tell you out about it. For example – some betting sites have plenty of sports, but only a handful of ways to bet on them – poor market selection. Or.. We have thoroughly tested and deposited with the top 20 betting sites of all time listed below. When it comes to the other couple of hundred betting sites, while we do look at what features are available, as well as what the user experience feels like, we don’t always deposit and play with every single bookmaker – though it still happens. We believe our time is better utilised finding value and deals for you!

Always make sure the site is regulated by the relevant gambling authority (e.g., UK Gambling Commission). Free bets almost always cannot be cashed out. Cash-out features apply only to bets placed with real money. It means your winnings or bonus will be credited as free bet tokens instead of cash. For example, a promotion may say: “Bet £10, get £10 paid in free bets.” A cashback free bet refunds your losing qualifying bet in the form of a free bet token, not cash.
At oddschecker, we believe in safe and responsible gambling. Gambling should be a form of entertainment and not a source of stress or financial difficulty. That’s why, under the guidance of the UK Gambling Commission, all licensed operators must provide a range of responsible gambling tools to help you stay in control. If you ever feel that gambling is starting to affect you or someone you care about, free support is available. Charities and organisations like GamCare, BeGambleAware, and the National Gambling Helpline offer free, confidential advice and practical help when you need it.

The bookie hosts both a regular sportsbook and a betting exchange, making it a versatile and valuable tool for any punter.
The two founders, Eskil and Jens, are still involved, but they are no longer the main writers for the site. As BookiesBonuses grew into a seed for more projects over the years, they had to take on oversight roles. The founders had a background in poker, but were also interested in sports betting. With time they realized there was no service for an easy comparison bet betting promo codes for existing customers of welcome offers online. Initially, the site was really just a product for themselves and their friends, aggregating the offers in order to compare.
Over the coming years, more people found BookiesBonuses and appreciated the service it provided when looking for a good bookmaker. It became a go-to product for a lot of British punters. In 2012, it got its first major facelift, as the two founders were joined by a developer. In 2016, the trio decided to make the side project their full-time job and launched several similar sites in different countries. Also, at this time they realized they needed more hands on deck and recruited a new project leader for BookiesBonuses.
That is when it got its second facelift. Since English is an international language, the website also garnered interest from many other nations. To cater to these punters, information about bookmakers in these countries was also added to the site. Today, we cover 18 countries outside of the UK. The market has changed over the years, but our goal of helping punters find a betting site for their needs remains. I like the variety of football betting markets, and the plethora of payment methods with low deposit limits.

They're well-known for their football and horse racing markets and promotions, and are ideal for most punters' needs.
You just need to fill out the following information: Indicate if there are any specific terms, for example, a complex bet like a lucky 15. Yes, free bets don’t cost you money directly, but they usually come with conditions, such as placing a qualifying bet first or meeting minimum odds requirements. You can’t withdraw a free bet stake itself. Free bets cannot be withdrawn as cash. You can only withdraw any winnings generated from using the free bet (minus the free bet stake).
Many bookmakers require you to deposit and place a qualifying bet. Some offers are “no-deposit free bets,” but these are less common. Usually yes, but some offers have restrictions. Always check the terms, as certain free bets may limit you to specific sports, markets, or minimum odds. If your free bet wins, you’ll receive the profit from the bet, but not the free bet stake itself.
For example, a £10 free bet at odds of 5/1 would see a return of £50, not £60. Many UK free bet offers are restricted to UK & Ireland residents due to licensing rules. Oddschecker is an independent comparison and affiliate platform. We partner with bookmakers to list odds and offers but are not owned by a bookmaker. Yes—if you use licensed and reputable bookmakers.
