• Licensing: We also need to ensure that the site is legal, licensed and regulated. Anyone without a UK Gambling Commission licence won't be featured.
• Payments: A good betting sites should have a range of payment options, including debit cards, e-wallets, prepaid cards and more.
• Functionality: The bookmaker in question should have a well-designed and user-friendly interface.
• Mobile: Any bookmaker should have an accessible, easy to use app or mobile-optimised website.
• Customer support: If and when things do go wrong, it's important to know that you are in good hands and that your issues can be resolved swiftly.
• Betting markets: As well as having a solid range of sports, the best betting sites also have multiple markets available for each sport and league they offer.

• Gaming options: When it comes to the online casino side of a betting site, you want to have a quality selection of games to play.

Factors to Avoid When Betting Online

Betting on sport should be enjoyable and it’s hard to have a good time if you are worried about your online safety. After all, there are plenty of rogue betting sites out there who’ll happily take your money and leave you with nothing. So how do you figure out which betting sites to try and which to avoid? Here are few simple things to look out for:

Confusing Terms and Conditions

Any Betting Online UK site is only as good as its terms and conditions. After all, it is the small print that tells you what you are allowed to do and how the betting site will operate. As such, a betting site’s terms and conditions should be clear about everything from who can sign up to its platform to how much you can potentially win with your bets.

Terms and conditions are especially important when it comes to betting bonuses and offers. This is because it’s all too easy to be lured in by a promotion that promises you everything but ends up giving you nothing. Above all, avoid any betting site that fails to have any terms and conditions that tells you exactly how it works in a simple, easy to understand way.

Bad Customer Care

There’s nothing more annoying than bad customer support, and this is definitely true when it comes to betting sites. Ideally, you’ll want customer care that is available 24/7 via live chat, email, phone and social media. Plus there’s nothing like a good FAQ for explaining the basics of how the betting site works. If you encounter a betting site who makes it hard to get in touch with its customer care team, then that says a lot about how it treats its customers.

Lack of Licensing and Regulation

Betting Online UK sites are only allowed to legally operate if they have a license from the UK Gambling Commission. So if you see any betting site without such licensing, it tells you that this operator is acting illegally and that it will give you absolutely nothing in terms of customer protection.

What makes things a little more confusing is the fact that there are numerous online gambling authorities all over the world. Some of these authorities hold more value than others, and if you see a Curacao betting site, it’s best to leave it well alone.

Online Betting in the UK: Everything You Need to Know in 2025

If you're new to online betting or looking to brush up your knowledge about how it works in the United Kingdom, here are some of the key topics.

Legality of Online Betting

Online betting has been legal for decades now as long as the bettor is over the age of 18. The key piece of UK legislation came via the Gambling Act in 2005. This brought the previous laws into line with an industry that had moved on from simply betting in person at a bookmaker, on the racecourse or in a casino. When people can bet from anywhere at any time, it's important for the laws of the land to account for that. The act accounted for a host of requirements from the operators including licencing and promotion of responsible gambling.

There have been various updates to this legislation, including a major reform in September 2022 which includes additional requirements around protecting those at high risk of issues when betting. If you've bet online before you'll likely notice that online betting sites will usually verify your ID, sometimes as part of the sign up process to allow them to ensure against both underage gambling and money laundering laws.

Taxation of Betting Winnings

In 2025, there is no taxation of betting winnings in the United Kingdom. That's the same no matter how you win money, be it from sports betting, casinos, bingo, poker or any other type of gambling. You won't be asked to pay tax on it and no losses can be deducted from your other earnings either.

This means whatever you win from a bookmaker or casino is yours to keep without having to factor in giving a percentage to HMRC. The UK is one of the most liberal countries in this regard, perhaps because betting has been legal for a long time and events such as the Grand National are part of the culture.

History of Online Betting

The early days of online betting were the late 1990s. With the increase in popularity of the internet, some existing bookmaking brands, as well as new ones, began to spring up offering online bettors the chance to wager without being in a physical location around the turn of the millennium. The more people began to do things online, the more bookmakers recognised that this was an opportunity to make it easier for those who wanted to place a bet to do so at their convenience.

Betfair launched in June 2000, around the same time that bet365 was formed, although they didn't officially launch until 2001. From there, even more brands either started up online or moved part of their operations online to meet the growing trend. With the emergence of smartphones, faster and more affordable internet access, the online betting industry now accounts for a Gross Gaming Yield of over £6 billion. As of 2025, the UK has around 175 officially licenced brands operating and the industry employs around 100,000 people within the United Kingdom.
