Welcome to OnlineBetting.org.uk, your premier guide to the world of betting and gambling on the internet. Whatever your sport or game we are here to offer expert advice on where to place your bets, with recommendations and guidance based on a combined experience of over 40 years.
On the site we provide up to date and detailed reviews of all major UK bookmakers, as well as a handful of carefully selected online-only sportsbooks and casinos – all of which are licensed and regulated right here in the UK. As well as individual reviews, we have also written a number of guides which recommend bookies based on sport, bet types or offers so that you can find the best betting sites for your needs.
Whilst we prefer to give more detailed advice based on the features you’re looking for or sport you want to bet on, we also understand that some people just want a list of betting sites to try out for themselves. For this reason we’re kicking things off with a list of our favourite bookmakers. For details of promotions for existing customers see our reviews or visit or betting offers page.

Betfred: Bet £10 Get £50 In Free Bets

It is fair to say Betfred and its founder Fred Done are the most experienced British bookmaker there is today. They are still independent too, which is rare and a sign of how well they know their business. They have been around since the late 1960’s and have seen every major sporting event since the 1966 World Cup. Indeed, Fred and his brother Peter, placed a bet on England to win the 1966 World Cup and using those winnings set up their first betting shop.
Having seen it all before then it is no surprise that Betfred offer one of the best places to bet this summer. The self-proclaimed ‘Bonus King’ has had its finger on the betting public for over 50 years and so it is no surprise to see they have come up with a cracking offer that deserves our welcome offer of the month slot. If you plan to bet on the Premier League, Champions League, darts, snooker, racing or any other sports then we can think of no better deal.
The offer for new customers gives you £50 in Free Bets when you sign up using the code BETFRED50, deposit and bet £10 or more at Evens+ odds – do this within a week of joining. Then you can claim three £10 sports free bets to use on any market and 2 x £10 free bets you can use on accumulators with four or more selections. All the free bets are valid for one week.
New customers only. Register with BETFRED50. Deposit £10+ via Debit Card and place first bet £10+ at Evens (2.0)+ on Sports within 7 days to get 3 x £10 in Sports Free Bets & 2 x £10 in Acca Free Bets within 10 hours of settlement. 7-day expiry. Eligibility & payment exclusions apply. T&Cs apply.
New Customer Enhanced Odds Offers & Free Bets
In addition to the standard welcome free bets and bonuses you can read about on this site, many betting sites also run enhanced odds and free bet event specific specials.
If you are planning on betting on a certain event, especially a high profile one (e.g Premier League, Cheltenham, Wimbledon, etc.), then you can sometimes find added value compared to the general welcome offer by taking a bespoke deal.
At OnlineBetting.org.uk we focus on the nuts and bolts of betting but we also have a sister offers site that carefully screens new and existing customer promotions for all sports and events worth knowing about.
From the World Cup to the Ryder Cup, Champions League to Royal Ascot, if you are looking for something for a given sport or event then head over and take a look. We also list a wider range of betting sites if you would prefer to see a longer list of UK licensed operators.

What’s On & Upcoming Major Events
Below we list the major sporting events on now and upcoming to help you plan your betting.
Many bookies often give boosted odds and high value retention offers surrounding these feature events that can boost winnings or reduce loses for diligent punters.
It is often worth waiting until closer to an event start time to utilise the best prices, insurance offers, free bets, money back and other promotions available. You can visit our sister site, featured in the section above, LatestBettingOffers, for event specific odds and deals for both new and existing customers.
It’s the pinnacle of European club football and the competition every fan wants to win and this year with no less than six English teams in the competition and this means even more attention than before. Liverpool are of course the record English side in the competition and were finalists in 2018 and 2022 and won the competition in 2019 and they will be looking do to well this year.
This year, however, it will be last years champions PSG along with record champions Real Madrid who will be the clubs to beat. Man City will be up there again having now won their first Champions League in 2023 it could now open the floodgates and it is likely more wins will follow. Arsenal, Chelsea and even Newcastle cannot be discounted and if they make the knockout rounds anything is possible. Spurs seem a little more of an uncertainty but you never know with them.
Form 2024-25 the competition expanded to 36 teams with a new league phase replacing the group stage. This now means 8 league matches between September and January (no winter break anymore) with four home and four away ties all against different teams. The top 8 go straight to the last 16, those who finish 9-14 in the league contest a two legged play off in February with the 8 winners progressing to the last 16.
From that point it is a straight knockout as we are familiar with. The top 8 league teams are seeded at the last 16 stage but country protection is removed now. The knockout draw in February now also plots out the route to the final, as with the likes of the World Cup, which helps ensure the 8 seeded teams are more likely to make it to the later stages – as if the big teams needed anymore help.

The darts Premier League takes place from February to May every Thursday evening, it moves around each week meaning that 17 different venues across the UK and Europe will be used this year.
The format changed in 2022 and now takes place over 17 evenings with 8 players competing in a series of 16 mini-tournaments before a final play-off. For the first 16 nights players play quarters, semis and a final with the winner getting 5 league points and a £10k bonus, runner-up 3 points and losing semi-finalists 2 points.
The top 4 players in the league progress to the final play-offs and the final due to be staged in late May. The world’s eight best PDC players compete in the Premier League. Michael Van Gerwen won the 2022 and 2023 versions and is record holder with 7 titles, ahead of Phil Taylor with 6 titles. MVG also won four titles in a row between 2016-2019. Luke Littler won on his debut in 2024, only the third player to do so and the youngest winner in history. He also managed a 9-dart leg in the final. He seems to be the one to watch for the future.
The only player it seems that may stop Littler being completely dominant is Luke Humphries who beat Littler in the final in 2025 – despite Littler setting a new record of 45 points in the league phase to get there.
The event was only conceived in 2005 and yet has already become one of the most high profile events on the darts calendar, second only perhaps to the World Championship.
You can find some excellent linked free bets and price boosts, especially from the previous event sponsor Unibet. For nights 1 to 16 each match is best of 11 legs, the semi-finals best of 19 legs and the final best of 21 legs.

The French Open is the most unique of all the slams because it is contested on clay. Clay is the slowest surface and this means it is harder to smash your way through an opponent with big serves and returns. For players to win on clay they must play a slower tactical game and this is one of the major reasons the big names of the grass and hard courts don’t always perform well. Novak Djokovic, for example, has 3 French titles from 24 grand slams and Roger Federer 1 from 20 grand slams.
The king of clay is Rafa Nadal, the record winner has almost the opposite statistic with 14 wins at Roland Garros out of 22 total slams. He is now retired and went out in the first round in his final year, 2024, but that was to eventual finalist Zerev. He lost to another Spaniard in the final, Carlos Alcaraz, who repeated the feat in 2025 by beating Jannik Sinner. Is Alcaraz set to be the next Nadal? Don’t bet against it.
The women’s game by contrast is much more open on paper. Since 2004 only 6 different players have won the men’s title but by contrast 15 different players have won the women’s singles. Only Serena Williams, Maria Sharapova, Iga Świątek and Justin Henin have won it more than once in the last 18 years. Having said that Iga Świątek has won four since 2020 and matched the record for consecutive wins with three in succession between 2022 and 2024. Effectively it is Iga and if not then a very open field after that.

When the Derby and Oaks roll around each year we know that the summer is here and the flat racing season is in full swing. The fact that there is little else on in early June means that for the feature races like the Derby and Oaks classics punters can get some fantastic added value if you wait until a day before to place your bets.
Racing takes place over the Friday (Ladies Day), which features the Oaks, and Saturday (Derby Day), which of course features the Derby. These are just the two biggest races however out of 14 in total that include the group 1 Coronation Cup along with a further 2 group races, 2 listed races and some seriously competitive handicaps.
Epsom is synonymous with high level racing having seen horses running there since the mid-1600s. It is close enough to London to draw big crowds, and a lot of royalty, but far enough away to be set among the rolling green hills of the south downs.
Both the Oaks and the Derby are held over just over one and a half miles and are two of the five British classics. The winner can expect to take home in the region of £910,000 from a purse worth over £1.6M, for winning either race.

The 23rd World Cup takes place in the US, Canada, and Mexico, the first time the tournament has taken place across three different countries in the same competition. It is also the first time the competition has been extended to forty eight teams, so there is a stronger chance that home nations will take part. Matches are due to begin on the 11th of June.
Teams play three times in the group stage, once against each opponent in a round-robin. The top 2 then qualify for the new round of 32, along with the 8 best 3rd placed teams. This is a knockout round, leading to another knock out round of the final 16 teams, at which point the competition looks the same as it has done for decades, with a quarter, semi, and then final game to determine the winner.
With England reaching the semi-finals in 2018 and the final of Euro 2020 there was a high expectation last time around, but hopes are slightly more muted since they were knocked out in the quarter finals in 2022. There is no bigger event for bookies in a four-year cycle than the World Cup. It is so competitive that bookies push out their best promotions and odds, often loss-leading to get your custom. There is rarely a better time to sign up to bookies either as they run their most lucrative sign up deals at this time.

A little introduction to me, Matt.

I am a diehard Liverpool FC fan and I truly love my football but I also like watching and going to, Horse racing, Dog racing, Cricket, Tennis, Darts, F1, Rugby, Golf, Snooker, Boxing and even the odd NFL game. If you watch a sport or game in my opinion it is worth placing a bet on it but given the wide range of choice and offers available in the world of online betting it is often hard to know who to bet with. In my own experiences I have made some mistakes but I have found a lot of gems that can make betting on events a lot more fun, and profitable.
Maybe you want to find the best bookmaker for betting on football for example, or you might want to know how to bet with cash online, who offers Cash Out, live streaming, who has the best mobile app or who provides the best live betting – whatever your query or question we have complied a comprehensive resource to online betting to help answer it.
