Our Guide to UK Bookmakers and Online Betting Sites
The world of sports betting has undergone a dramatic transformation with the rise of online platforms. Gone are the days when punters were limited to their local betting shops. Today, UK bettors can choose from a wide range of bookmakers and online betting sites, each offering unique features, bonuses, and betting opportunities. This guide simplifies the process of finding the best platforms for your betting needs.
How to Pick the Right Betting Site
Selecting the ideal betting site requires careful consideration of several factors, including welcome bonuses, usability, betting markets, and more. Below, we break down the most important aspects to help you make an informed decision.
New Customer Welcome Bonuses
One of the main ways online bookmakers attract new customers is by offering welcome bonuses. These promotions often include:
- Free Bets: Bonus funds to place a bet without risking your own money.
- Deposit Match Bonuses: A percentage of your first deposit added as a bonus.
- Losing Bet Refunds: Refunds for your first bet if it loses.
When joining a new betting site, it’s crucial to understand the details of the welcome bonus, including the requirements to claim it. Each bookmaker’s terms and conditions will differ, so choose a bonus that aligns with your betting style.
Betting Offers for Existing Customers
To keep their customers engaged, online bookmakers regularly provide ongoing promotions, such as:
- Free Bet Clubs: Rewards for placing a set number of bets.
- Enhanced Odds: Boosted returns on selected events.
- Losing Bet Refunds: Insurance against narrowly missed outcomes.
Most betting sites have a dedicated “Promotions” section where you can browse their current offers. Our site reviews highlight the most generous and innovative promotions available, making it easier to choose the right bookmaker for you.

Site Appearance, Interface, and Usability
The usability of a betting site plays a key role in your overall experience. A well-designed platform should:
- Be visually appealing and easy to navigate.
- Allow you to quickly find betting markets and place bets.
- Provide an enjoyable and intuitive interface on both desktop and mobile devices.
The best bookmakers prioritize simplicity and efficiency, ensuring their platforms cater to users of all experience levels.
Betting Markets and Odds
When choosing a bookmaker, consider whether they offer betting markets for the sports and events you’re interested in. Leading sites provide:
- Coverage of a wide variety of sports, from football and horse racing to niche events.
- Deep betting markets with a range of bet types for each event.
Odds can vary significantly between bookmakers. It’s wise to have accounts with multiple betting sites, allowing you to compare odds and secure the best possible returns on your bets.
Live Streaming
Live-streaming has become a popular feature among online bookmakers. It enhances the betting experience by providing real-time coverage of events. The top sites offer:
- Extensive live-streaming options across a wide range of sports.
- Clear rules for accessing streams, such as requiring a bet on the event or simply logging into your account.
If live-streaming is important to you, check each bookmaker’s offerings and access requirements before signing up.

Mobile Betting
In today’s digital age, browsing the internet on a mobile device has become second nature—there’s even a good chance you’re reading this on your phone. Recognizing this trend, betting sites have significantly enhanced their mobile offerings. Most platforms are now fully optimized for mobile use, allowing you to access them seamlessly through your device’s browser.
However, not all betting sites offer the same mobile experience. Some are better tailored to mobile users, featuring smoother navigation and faster load times. Others excel in specific features, like live streaming. If mobile betting is your preference, it’s worth exploring and comparing platforms to find the one that best suits your needs.

Mobile Betting Apps
While accessing betting sites via a mobile browser is convenient, downloading a dedicated mobile app can make the process even easier. Many bookmakers now offer mobile apps that are designed for efficiency and ease of use. With just a few taps, you can access your account, place bets, and explore features without needing to type a web address into your browser.
When choosing a bookmaker, check whether they offer a mobile app and evaluate its functionality. A well-designed app can save time and enhance your overall betting experience.
Cash Out
One of the most exciting innovations in online betting is the Cash Out feature. This concept, which originated with online betting exchanges, allows punters to lock in profits or minimize losses before an event ends. Traditional bookmakers quickly adopted and expanded on this idea, making it a staple feature on many betting sites.
In simple terms, Cash Out lets you close a bet early for a price offered by the bookmaker. However, the availability and functionality of this feature vary widely between platforms. Some offer basic Cash Out, while others provide advanced options like Partial Cash Out, enabling you to close part of a bet while letting the rest run. Additionally, certain bookmakers include Cash Out on all bets, whereas others restrict it to specific markets. If this feature is important to you, compare bookmakers to determine which one best meets your needs.
Banking
Banking—the process of making deposits and withdrawals—is a critical aspect of online betting that can sometimes be overlooked. Ensuring that a betting site supports your preferred payment methods is essential for a hassle-free experience.
Different sites have varying deposit and withdrawal options, including credit/debit cards, e-wallets, and bank transfers. It’s also important to consider factors like transaction limits and processing times. Before committing to a bookmaker, verify that their banking options align with your requirements.
Customer Services
Although you may rarely need to contact customer support, having reliable assistance when issues arise is invaluable. The quality and accessibility of customer service can vary significantly between betting sites.
Look for bookmakers that offer multiple ways to reach support, such as 24/7 live chat, phone support, email, or even assistance via social media platforms like X (formerly Twitter). Some sites may only provide limited support hours or slower response times. If responsive and effective customer service is a priority, take this into account when choosing a bookmaker.
What about Bet Builders?
What is a Bet Builder?
A Bet Builder is a feature offered by many UK online betting sites that allows bettors to create personalised bets by combining multiple selections from the same event. This feature is most commonly used for football matches but is increasingly available for other sports such as tennis and basketball.
How Does a Bet Builder Work?
Instead of placing separate bets on different outcomes, a Bet Builder lets you combine several bets into one single wager. The combined odds are then calculated, offering potentially higher payouts. For example, in a football match, you could build a bet with:
- Both teams to score
- Over 2.5 goals
- A specific player to score
- Total number of corners
If all these selections win, you win your Bet Builder bet. If one loses, the entire bet is lost.
Advantages of Using a Bet Builder
- Customisation – You can tailor your bet exactly how you want.
- Enhanced Odds – Combining multiple bets increases the potential payout.
- More Engagement – It adds extra excitement to watching the event.
- Available on Many Sports – While primarily used for football, many bookmakers now offer it on other sports.
How to Use a Bet Builder
- Choose Your Event – Select the match or game you want to bet on.
- Look for the Bet Builder Feature – Usually found in the betting markets for that event.
- Select Your Outcomes – Pick multiple betting options from the same event.
- Review Your Odds – The site will calculate the total odds of your Bet Builder bet.
- Place Your Bet – Confirm and stake your wager.
Popular UK Betting Sites Offering Bet Builder
Most major UK bookmakers offer a Bet Builder feature, including:
- Bet365 – One of the pioneers of the feature, with extensive market options.
- Sky Bet – Offers the “Request A Bet” function, which is similar.
- Paddy Power – Provides Bet Builder across multiple sports.
- William Hill – Strong Bet Builder markets with cash-out options.
- Betfair – Also offers a “Same Game Multi” option.
Bet Builder Tips
- Do Your Research – Analyse stats and form before making selections.
- Don’t Overload Your Bet – Too many selections reduce your chances of winning.
- Consider Player Form and Team Tactics – Individual and team performances influence outcomes.
- Use Cash Out Wisely – Some bookmakers offer cash-out options, which may be of interest if your bet is close to winning.
Final Thoughts
Bet Builder is a fantastic way to enhance your betting experience, giving you full control over your wagers and the chance for bigger returns. However, always gamble responsibly and set limits on your bets to stay in control.

Are the Betting Sites listed here safe?
Quite simply, yes. All the online bookmakers that are listed on this site are strictly licensed by the United Kingdom Gambling Commission (UKGC). To operate in the UK gambling sector betting sites must have a licence granted by the UKGC, and to get that the bookie must pass some vigorous tests, and adhere to some strict rules. One such rule is that all betting companies must ringfence all customer’s funds, so that if the company gets into any difficulty, the customer’s funds are safe and can be withdrawn. There must also be a host of safer gambling checks in place, to help with any gambling problems, as well as tools, so customers can make sure they stay on top of how much they are depositing and gambling.
What Restrictions Are There When Opening A New Betting Account?
Age
All people wishing to open a betting account and bet with the bookies in the UK must be 18 years of age or older.
Location
All the online bookmakers we list here are licensed by the UKGC so they are not allowed to offer gambling services to people in territories where gambling is forbidden. Our site is created for people residing in the United Kingdom, so if you are currently based elsewhere, it will be your responsibility to make sure you can legally bet with these bookmakers.
Only Allowed 1 Account Per Bookmaker
If you already have an online betting account with a bookmaker, you will not be able to open another one. Although you can open an account with as many online bookmakers as you want, you’ll only be allowed to have 1 with each bookie.
What Are The Best UK Betting Sites in 2025?
As we have mentioned above, each betting site is different, and each online bookmaker will have different pro’s and con’s. That said, some betting sites do stand out as better than most of the competition. For example, Bet365 is considered by many as the leading online betting site in the world, whereas Betfred are well known for having some of the best and most generous betting offers out of all the bookies.
Ultimately though, as each punter will have different needs and demands from their betting site, and each betting site has different qualities, it is important to compare which betting sites are right for you.
Will There Be New Bookies Listed Here?
In short, yes. Here at Free Bets UK, we are always looking for new bookies that have entered the UK market. It is worth saying though, not all betting sites will be listed here if we don’t think they are good enough, they have to be sites that we can genuinely recommend to our users. However, if a new online bookmaker cuts the mustard, and we think they are good enough to recommend, we will give them our full, and independent review. So far in 2025 the new bookies below are ones that have hit the highest standards and got themselves listed on our site:
- Matchbook
- BresBet
- Star Sports
- Kwiff
- Fitzdares
- EasyBet
- QuickBet
- 7Bet
Currently, we have two more online bookies that are going under our thorough review process, and we are always on the lookout for new betting sites to bring you.
So, Not All UK Betting Sites Are Listed Here?
Nope, there are quite a few UK online bookmakers that you won’t find listed with us, for numerous reasons. The main reason is, basically, we think their betting sites are poor, and couldn’t recommend them to anyone. If we don’t bet with them, we couldn’t send other people there to bet with them. We won’t embarrass which betting sites these are, but if they were good enough, they’d simply be listed.
