Sign-up bonuses are promotional offers designed for new customers who register and make their first qualifying deposit. These rewards usually come in the form of free bets or extra funds credited after meeting basic wagering conditions. The best current new customer offers include Betfred (£50), 21LuckyBet (£50), and Unibet (£40).

Betfred – Sign-up bonus £50

Overview: The terms of this offer are standard and transparent for the UK market. After making a qualifying deposit and placing your first bet, you’ll receive multiple free bets with no wagering requirements.

Verdict: This offer allows players to explore key sportsbook features through both single and accumulator bets. It stands out for its total bonus value of £50 and minimal wagering restrictions, making it one of the most balanced options available.

21LuckyBet – Sign-up bonus £50

Overview: Players simply need to make a qualifying deposit, place a bet according to the requirements, and receive the allocated free bet in their account after settlement. The credited free bet must be wagered once within seven days.

Verdict: Although this welcome offer is also £50, the operator sets stricter conditions for use. The free bet must be used in full; there is a maximum cash-out limit of £200, and the winnings from the free bet are subject to a one-time wagering requirement. Qualifying odds of 1.7 apply to the initial bet.

Unibet – Sign-up bonus £40

Overview: Unibet offers new players a welcome bonus for use on both sports betting and casino games. Register, make a deposit using any method except prepaid cards, Skrill, or Neteller, place a qualifying bet, and the bonuses will be credited to your account automatically.

Verdict: While the Free Bet can be used on pre-match and in-play markets, the promotion comes with strict qualifying requirements and exclusions on certain payment methods. It is suitable for players looking to explore multiple sections of the platform, but the wagering conditions on the casino bonus are relatively high.

Deposit match bonuses provide new players with extra funds equal to a percentage of their first deposit, allowing them to explore a wider range of games and betting markets. In the UK, this type of offer is most commonly applied to online casino products rather than sports betting. The top current deposit match offers include Luckster (£200), Karamba (£100), and 7bet (£50).

Luckster – Deposit match bonus £200

Overview: Simply make a qualifying deposit to receive the bonus automatically. Once you meet the wagering requirements, additional deposit bonuses become available.

Verdict: A rare and unconventional welcome offer is available to all new Luckster players. The bonus stands out for its simplicity. Just make a minimum qualifying deposit of £10 and the funds will be automatically credited to your account. The main drawback is that the offer applies exclusively to the casino section.

Karamba – Deposit match bonus £100

Overview: To receive the Karamba welcome bonus, you need to register and make a qualifying deposit. The funds will be automatically credited to your account.

Verdict: Compared to competitors, the operator offers a balanced promotion that is straightforward to claim and easy to understand. In our ranking, the bonus takes second place because the bonus amount reaches £100, and the wagering requirements for the credited funds are relatively strict.

7bet – Deposit match bonus £50

Overview: The 7bet First Deposit Casino Bonus gives new players a 100% match on their initial deposit up to £50. Bonus funds are credited immediately and can be used on eligible casino games. Winnings from the bonus must be wagered 40 times within 30 days before they can be withdrawn.

Verdict: The 7bet welcome bonus rounds out our list of top deposit match offers. It provides transparent terms but comes with higher wagering requirements and a relatively small total bonus amount. On the positive side, there are no restrictions on how the bonus can be used across the platform.

A Free bet is a promotional stake given to players to place a bet without using their own funds, with any winnings credited according to the offer’s terms. Free bets may have requirements such as minimum odds or eligible markets. The best free bet offers are available at NetBet, Ladbrokes, and BetVictor.

BetVictor Free bets £20

Overview: The free bet is offered as a welcome bonus for sports betting and is available only to newly registered players. To claim it, make a qualifying deposit and place a qualifying bet; the free bet will be credited to your account automatically.

Verdict: The BetVictor offer tops our list of promotions due to its interesting bonus mechanics. New players receive two free bets for accumulator and single bets, with the second credited 24 hours after the first. The main drawback is the small total bonus amount of just £20.

NetBet Free bets £5

Overview: The bonus is awarded for accumulator bets placed on the English Premier League. Players receive a Free Bet after placing a qualifying wager. The offer is limited to one activation per week and is valid only on football markets.

Verdict: This Betfred promotion is easy to participate in and provides a clear reward for accumulator bets. The bonus can be claimed weekly, making it suitable for both new and regular players. However, the small Free Bet amount and the restriction to Premier League accumulators limit its overall usability.

Ladbrokes Free bets £5

Overview: Place single or cumulative bets on American sports totalling £25 and the player receives a £5 bonus. The bonus can be used on Live Casino games with no additional wagering requirements.

Verdict: The Ladbrokes £5 Live Casino Bonus is a straightforward weekly promotion that rewards players for engaging with American sports markets. Its low wagering requirement makes it easy to convert into real cash. However, the small bonus amount and limited eligible markets restrict its overall appeal. Despite this, it is suitable for both new and existing players.

A money-back bonus is a type of sportsbook promotion where players receive a refund of their stake if a bet loses, either partially or in full, under specific conditions. These bonuses are usually applied automatically or credited after the qualifying bet has been settled. The top current offers for money-back bonuses are from William Hill, Unibet, and Paddy Power.

Unibet – Money-back Bonus £20

Overview: Bettors can place safe real-money bets on horse races. If your selected horse finishes second or third, you will receive your stake back as a Free Bet.

Verdict: This Unibet promotion provides a practical form of insurance for horse racing fans, offering a benefit even if your selection finishes second or third. The combination of cash and Free Bets makes the offer flexible for different betting preferences. However, its limited availability and the specificity of certain races mean it is best suited for regular horse racing enthusiasts who closely follow the schedule.

Paddy Power – Money-back Bonus £10

Overview: Place a pre-race single or Each-Way bet on any selected greyhound race. If your chosen dog finishes 2nd or 3rd to the SP favourite, you’ll receive your stake back as a free bet up to £10. Free bets are credited by 12 PM the following day and remain valid for 7 days, usable on any greyhound market.

Verdict: Paddy Power allows bettors to place less risky bets on greyhounds. An automatic refund of your stake means you don’t have to follow the race constantly. However, this promotion is not available for all races, so it may not suit every player.

William Hill – Money-back Bonus

Overview: The Moneyback Bonus refunds the stake of single bets placed on the Combined Trap Challenge if the selected trap has no winners. The promotion requires a minimum of 20 races to take place and a qualifying bet of any stake from the main balance. Refunds are credited to the main account balance, and no wagering requirements apply.

Verdict: The William Hill Moneyback bonus offers players a clear safety mechanism for betting on the Combined Trap Challenge. Its main advantage is the automatic calculation and refund process, while the lack of clearly defined limits may cause some inconvenience for players.

Referral bonuses reward players for inviting friends to join a sportsbook. Typically, when a referred friend registers, deposits, or places a bet, both the referrer and the friend receive a bonus, which can be in the form of free bets, bonus funds, or other rewards. Top UK sportsbooks offering referral bonuses: Paddy Power, Betfair, and Dabble.

Paddy Power – Referral bonus up to £60

Overview: Each verified player receives a unique promo code (link) to invite friends. After the friend registers, makes a qualifying deposit, and places a bet, both receive a bonus credited to their account.

Verdict: Paddy Power offers additional rewards of up to £60 for referred friends. Simple conditions make it easy to enjoy a better gaming experience. With transparent requirements and a progressive reward system, this operator ranks first on our list.

Betfair – Referral bonus up to £50

Overview: The same referral bonus system applies: you invite a friend, they make a deposit and place a qualifying bet, and you receive a free bet. You can refer up to five friends per month; additional referrals do not qualify for the bonus.

Verdict: Betfair offers a simple way to earn up to £50 in free bets, with no wagering requirements. Despite the easier invitation conditions, the lower reward compared to competitors places it in second position.

Dabble – Referral bonus up to £10

Overview: The player needs to go to their gaming profile, copy their unique referral link, and share it with a friend. The friend must follow the link, complete registration, make a qualifying deposit, and place a bet. Once all requirements are met, the Free Bet will be credited to your account within two hours.

Verdict: In general, Dabble's referral program offers clear and straightforward participation terms, allowing players to earn £10 for each friend they invite. The absence of wagering requirements on the Free Bet helped the bookmaker secure third place in our ranking.

Accumulator boosts increase your winnings on multiple bets, adding a percentage to your total payout depending on the number of selections in your bet slip. Top offers include 7bet with up to 75%, Unibet up to 40%, and bet365 up to 100%.

bet365 – Accumulator Boosts up to 100%

Overview: This convenient Accumulator Boost promotion activates automatically when creating an acca with more than two selections. The more events you add to your bet slip, the higher the final payout multiplier, up to 100%.

Verdict: A popular promotional offer across the UK, yet bet365 stands out with the most favourable conditions for its use. A small number of required selections, a low qualifying odds threshold, and a generous maximum boost make it the clear leader in our ranking.

7bet – Accumulator Boosts up to 75%

Overview: To receive your winnings boost, simply log in to your account, go to the Sports section, and start building your bet slip. The Acca Boost offer activates automatically once you add 3 or more selections and will be displayed on your coupon. Your boosted winnings will be credited automatically once all bets are settled successfully.

Verdict: Overall, the accumulator boost from 7bet features similar mechanics but comes with slightly different qualifying requirements. The key highlights include a maximum bonus of 75%, a minimum odds requirement of 1.5 per selection, and activation starting from three or more picks. These conditions place the operator firmly in second position on our list.

Unibet – Accumulator Boosts up to 40%

Overview: You can earn up to a 40% boost on your winnings every day by placing accumulator bets. To qualify, simply create an acca with three or more selections on horse racing or greyhound events, with a maximum stake of £20.

Verdict: Although the maximum boost is capped at 40%, Unibet stands out thanks to its accessible conditions. The first 10% bonus starts from only three selections, and this lower entry threshold, combined with fair returns, secures Unibet the third spot in our ranking.
