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.

Welcome Offer of the Month
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.

The Premier League is the worlds biggest sporting competition in terms of revenue, number of people watching, wages, attendance and pretty much any other stat you want to look at; including betting, accounting for over half of bets placed on football in the UK.
Let’s face it the league is elitist and based on money, and for a long time this caused stagnation with three teams dominating the first 20 years; Man Utd, Chelsea and Arsenal. Lately, however, the league has gained a new competitive streak, most notably with Leicester winning in 2015 and then three new dominant forces arising in Arsenal, Liverpool and Man City, who look set to continue their battle in 2023-24, in the way United and Arsenal did 15 years ago – that is except the level is now much higher, as seen with Liverpool coming second in 2019 with an astonishing 97 points.
In the UK 70% of bets are placed on football and nearly three quarters of those wagers go on the Premier League, making this one event responsible for around half of all bets placed. Considering this if you bet on the PL you would be insane not to search around for the best offers and odds from our leading bookies. Read our detailed guide for more.

It’s the pinnacle of European club football and the competition every fan wants to win and this year with no less than four 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 having missed out in 2024.
This year, however, it will be last years champions Real Madrid who will be the club to beat with now 15 titles to their name, winning in 2024 against a Dortmund team that were far better – Madrid just always find a way. Man City will be favourites 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 and even Aston Villa cannot be discounted and if they make the knockout rounds anything is possible.
Form 2024-25 the competition has expanded again 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 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.

Without question the worlds biggest and most challenging horse race. The 4 mile 2 1/2 furlong grade 3 steeplechase requires horses to jump now less than 30 fences, many of which are over 5 feet high and include famous obstacles such as Beecher’s Brook and The Chair.
In 2020 the Grand National race at Aintree was cancelled due to the coronavirus pandemic, the first time in history the meeting has been cancelled during peace time. Since then the race has regained it’s position as the greatest races in the world. In 2021 the race was held without fans but history was still made as Rachael Blackmore became the first woman jockey to win the big race in its history. In the two years that followed the race saw two favourites winning, the first time that happened in consecutive years since 1894.
The race has undergone some recent changes. The field has been reduced to 34 from 40 and the race now starts earlier at 4pm. This is to make the race safer, although it also makes it a bit less variable with favourites now doing better than before. Still 21 horses finished the race in 2024 and that was the highest since 1992 so the race is still a significant spectacle.
Last year the National attracted over £300 million in stakes, and that is only counting the legal bets. To say the event is a betting phenomenon wouldn’t do it justice, pretty much everyone who has ever bet has done so on this race, and more often than not it is the first bet people make.
It is surprising that many bookies shy away from the National, partly because they can’t cope with the demands of so many people wanting to have a punt. Many bookies cancel their offers and even sign ups on National day, so if you want to get added value this year it is recommended you sign up in advance. If you wait until a few days before to bet you will also find many of the better sites offer 6 places each-way.
Don’t forget also that the National is only one race among a 3 day festival starting on Thursday, and you can find many offers and specials for these other races too.

A little introduction to me, Matt. I have been betting for many years in all formats, I love all sports and games and as we all know there is no better way to get into an event than by having a cheeky flutter.

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.
