Bet £10 & Get £30 in Free Bets
What are Betting Sign up Offers?
Betting sign up offers are promotions that bookmakers provide exclusively to brand-new customers. Also called welcome offers, they usually involve new customers receiving a reward after placing their first qualifying bet or deposit. As bookmakers are keen to recruit new players, sign-up offers tend to be generous, allowing players to scoop up sizable rewards.
As we will later discuss, these betting offers can take various forms, but there are some standard examples. In the UK, you can often expect to see deals like “Bet £10 Get £30 in Free Bets”. With this, players need to bet £10 of their own money to earn £30 in free bet tokens. Another example offer is “Up to £30 back as a free bet if your first bet loses.”
Regardless of the new customer betting offer a bookmaker provides, they are designed to give players a valuable boost when starting out.
Sports Betting Sign up Bonuses
Most sports betting sign-up bonuses involve giving players free bets after they bet a certain amount. Usually, players will need to bet £10 to get between £10 and £30 in free bets, but you can find offers with a lower qualifying amount. Other sports welcome offers you may find include risk-free wagers, which give you money back if your first bet loses. Enhanced odds on a selected big sporting event, usually football or horse racing, are also available.
Casino Welcome Offers
Casino welcome offers typically feature a deposit bonus and/or free spins. With a deposit bonus, casinos match a player’s first deposit by a specific percentage up to a fixed limit. For example, a 100% bonus up to £100 means that if you deposit £20, you get an extra £20 in bonus funds. Free spins reward players with a set number of spins on popular slot games, giving them a chance to win without risking their own money.
Bingo New Customer Offers
Many sportsbooks and casinos with a dedicated bingo page provide betting offers that new account users can claim when playing the popular numbered balls game. Usually, such offers require players to bet an amount, often £10, to unlock free bingo tickets or bonus funds restricted to bingo. It is also common to see new customer offers for bingo that include free spins.
How to Use Welcome Offers?
Claiming a welcome offer varies by site, but here is a general guide.
- Pick one of the welcome bonus betting sites you would like to try.
- Head to the brand’s website or mobile app and open the registration form.
- On the form, if required, select your desired offer or enter the relevant promo code.
- Make a qualifying deposit for the offer.
- Make a qualifying bet, or bets, if required.
- For deposit-linked bonuses, you should receive your bonus immediately after payment. For those tied to qualifying bets, in most cases, you need to wait for the bets to settle before getting your bonus.
Types of Betting Sign-up Offers
The types of sign-up bonus betting sites provide come in different forms. Some give free bets, others match your deposit, while a few require no deposit at all. Below, we break down the most common types of welcome offers you will find across trusted UK platforms.
Free Bonus on Registration
A free bonus on registration is one of the easiest ways to get started. These betting sites reward new users simply for signing up, with no deposit needed. The reward is often small, but it gives players a free shot at real winnings. Beginners who want to explore the platform before committing funds often seek a free bonus on registration with betting sites.
Free Bet Sign Up Offers
Free bets are one of the most common betting sites’ sign up offers. With these, players place a qualifying bet and receive bonus bets in return. “Bet £10, Get £20 in Free Bets” is a typical offer. In some cases, players can meet the qualifying amount across bets, rather than having to place a single bet. Normally, players will need to wait for their qualifying bets to settle before they receive the free bet(s). Bookmakers often award free bets in small denominations such as 4 x £5, making them more flexible.
Free Spins Sign Up Offers
One of the best betting sign up offers for casino enthusiasts is free spins. With them, players will receive a fixed number of spins they can play on a slot or across a range of specified slots. To unlock the free spins, players usually have to bet a certain amount. For example, bet £10 and get 100 free spins. Free spins are almost always worth £0.10 each.
When players have to wager to unlock free spins, free spin winnings normally have no wagering requirements. For sign-up offers providing free spins with just a deposit, however, you should expect wagering terms.
No Deposit Welcome Bonuses
No deposit welcome bonuses are rare, but they are not completely extinct. With them, players get a bonus, whether it be bonus funds or free spins, without any payment required. The absence of a deposit makes them perfect for beginners who want to test the waters. Betting welcome bonuses do not come much better than no deposit offers, as they carry no financial risk but can lead to real rewards. Be aware, though, that winning from no deposit bonuses UK usually have an upper limit, often in the region of £50.
Cashback Sign Up Bonus
When looking at sign up bonus betting sites, cashback deals offer something a bit different. What they give is a refund on a player’s first bet, should it lose. Most cashback offers provide a full refund, up to a fixed limit like £30, but others will only refund a percentage, e.g. 50%. Normally, bookies pay the refund as bonus credit, rather than cash. This means it is not completely risk-free.
Should your bet win, you keep the full profit as usual, and the cashback offer simply does not activate.
Matched Deposit Welcome Offer
An extremely common welcome bonus you will find at casino sites is a matched deposit offer. The site matches your first deposit by a set percentage, often 100% and up to an upper limit (e.g., £50). So, if you deposit £50, you will receive £50 extra in bonus funds, giving you £100 to play with. A 100% bonus is the standard percentage, but you can occasionally find higher.
Starting your casino journey with bonus funds from a matched deposit offer is a great way to explore games and boost your balance early on. However, it is important to note that these bonuses usually come with high wagering requirements.
Odds Boost New Customers Offer
Some welcome offers betting sites provide include huge odds boosts for big sporting events. Normally, this involves boosting the odds on a horse to win a race or a football team to win a match. Whatever the sport/event, bookies will usually pick the market favourite as they know this is an outcome punters will want to back. This can see odds jump up massively from something like 8/13 to 50/1.
Given the extent of the increase, bookmakers usually cap new players to a £1 bet. They may also pay out enhanced odds winnings in the form of free bets, rather than cash.
UKGC Rules for Betting Sign-Up Bonuses
For any online betting site offering bonuses for new customers, they need to adhere to the UK Gambling Commission and Advertising Standards Authority (ASA) rules. To comply with both, sites should include clear terms and conditions, not featuring any wording that is likely to mislead customers. Key terms like maximum win limits, maximum bonuses and wager requirements must also be easily visible, not buried in the small print.
Additionally, a bookmaker should clarify eligibility terms, such as players being 18+ and residing in the United Kingdom. Although the ASA bans several gambling adverts per year, it is rarely because of a lack of transparency. There was one example in 2024, though, involving William Hill, as they did not prominently show payment restrictions.
The Gambling Commission is introducing new rules regarding promotions in December 2025. Gambling businesses will be banned from offers that require consumers to engage in two or more types of gambling, like betting and slots. They will also be unable to impose wagering requirements greater than 10x.
Terms and Conditions of New Customer Offers
When claiming online bookmakers’ sign up offers, it is important to understand the key terms and conditions. Here are the main things to look out for:
- Minimum Deposit: The smallest amount you must deposit to qualify for an offer.
- Minimum Odds: The lowest odds allowed on qualifying bets to count toward an offer.
- Wagering Requirements: How many times you must bet the bonus amount before withdrawing winnings.
- Wagering Contributions: Wagering contributions vary by bet type and game, with some counting 100%, others 50%, or even 0%.
- Maximum Bet: Betting sites may set a maximum bet size when there is an active casino bonus.
- Expiry Period: How long you have to use the bonus or free bets before they expire.
- Eligible Markets: Specific sports, esports, games, or bet types where the offer applies. This can apply when claiming the offer or to the bonus itself.
- Payment Method Restrictions: Some offers exclude certain deposit methods like e-wallets or prepaid cards.
- Winnings Limit: The maximum amount you can earn in withdrawable cash from bonus winnings.
- Bonus Abuse Rules: Accounts suspected of abuse may have offers voided or closed. This includes making multiple accounts to claim a new customer offer more than once.
What to Look For When Choosing a Sign-Up Offer?
When looking at all the new customer offers betting sites provide, look for good value, fair terms, and bonus types that suit your style. Pay close attention to wagering requirements and minimum odds, as these impact how easily you can use the bonus. Be mindful of the expiry period so you avoid losing your bonus.
It is also important to consider whether the offer applies to the sports or games you prefer. You do not want to be stuck playing games you do not enjoy, or betting on sports you know nothing about. Finally, make sure there are no hidden payment method restrictions or exclusions that could limit your access to the bonus.

Strategies for Using Welcome Bonuses Effectively
Using a betting site’s welcome bonus wisely can boost your betting experience and increase your chances of winning. First, always read the terms and conditions carefully. Pay special attention to wagering requirements, minimum odds, and expiry dates. These rules affect how and when you can withdraw your winnings.
Second, choose bonuses that suit your betting style. If you like low-risk bets, look for cashback offers or those with a low qualifying bet amount. If you prefer bigger wins, matched deposit bonuses or price boosts might be better.
Third, manage your bankroll carefully. Do not bet more than you can afford just to meet wagering requirements or the qualification terms of a bonus. Setting up daily, weekly and monthly deposit limits is a sensible way to help keep your spending under control.
Fourth, if possible, consider splitting your bets to spread risk and increase your chances of meeting the bonus terms without losing your entire stake at once. When a welcome offer requires you to bet £10, for example, this does not necessarily mean betting it on a single wager.
Finally, keep track of your bonuses and deadlines. Missing an expiry date can mean losing the bonus and any associated winnings. Also, be mindful that some sign-up offers have a fixed deadline, so you need to opt in before it disappears.

The best welcome bonus betting sites not only provide top value but also clear terms.

FAQs
Can I get a new customer offer from more than one betting site?
Yes, you can redeem offers at as many betting sites with a sign-up bonus as you like. This applies even if they are part of the same parent company, so you can claim a Ladbrokes and Coral welcome offer, for instance.
Can I withdraw my welcome bonus?
With most betting sites’ new customer offers, you can only withdraw your bonus winnings after meeting the wagering requirements. You will not be able to withdraw funds located in your account’s bonus wallet.
Do I need a promo code for UK Betting offers?
Some UK betting offers require a promo code to claim the bonus, but most activate automatically or by a simple ‘opt-in’. When an offer requires a code, it will usually feature prominently on the advert.
Should I make a deposit to claim a new customer offer?
Betting sites with a welcome bonus will usually require an initial deposit. No deposit offers still exist, but they are rare. When depositing, ensure you use a method that does not exclude you from the bonus.
Is it better to choose a free bet welcome bonus or a free spins sign-up offer?
Choosing between a free bet welcome bonus or a free spins sign up offer depends entirely on your preferences. Both types of betting sites’ welcome offers have their merit, but it depends on whether you want something skill-based (free bet) or luck-based (free spins).
