Let’s explore the types of betting offers you can find across top UK bookmakers like Unibet, 10bet, Betway, and BetVictor.

Free Bets

Free bet offers are a staple in the promotional arsenal of bookmakers. At 10bet, for example, players can receive a £5 free bet for staking £40 or more on sports, with cricket bets slightly higher at £6. Betway also offers free bets through its Free Bet Club, rewarding players with £10 in free bets when they wager £25 on sports trebles and accumulators.

When evaluating free bet offers, consider the following key points:

Wagering requirements: Any requirements to bet additional funds before withdrawing winnings from the free bet. For example, winnings from a free bet might need to be wagered three times on odds of 1.5 or higher before they can be withdrawn.

Minimum odds: The lowest odds at which you can place your free bet. For example, the terms may require that the free bet be placed on events with odds of at least 1.5.

Expiration: How long you have to use the free bet before it expires. A common term might be that the free bet expires 7 days after it is credited to your account.

Market restrictions: Some free bets may only be applicable for certain sports or events. For instance, a free bet might be valid only for football accumulators or horse racing.

What could be a better welcome handshake than a free £50?

An entire nifty fifty just for having an opening £10 wager! Although not every bookmaker offers this enhancement by any means, there are some out there that do and they are worth their weight in gold.

With so many bookies in the game these days, both old and new, punters can afford to be quite discerning in deciding which of them to give your business to. The following bookmakers are not only top of the tree when it comes to dishing out freebies, but they are also superb sites in their own right, offering a full range of sports and markets, in-play betting opportunities and, so crucial in this technological age, fantastic gaming on the go, via their apps.

Here’s a closer look at these wagering wonders that are happy to slip you half a ton just for getting started with them. 

The 10 Bet Welcome Offer is a 50% Matched Deposit Bonus of up to £50. Just register your account and deposit £10 using the code SPORT in the cashier section. Once the Matched Deposit Bonus has hit your account, there is an 8x wagering requirement in place. This means that the Bonus must be wagered 8 times before any winnings can be withdrawn as cash. You must be sure to use the Bonus within 60 days. Note that deposits made via Skrill and Neteller will not be valid for this offer.   

New punters can claim £50 in Bonuses when you register your account using the code “Welcome 50”. Your first £10 bet must be at odds of Evens (2.0) or greater and, once that has been settled, you will automatically receive the following;  

• £20 worth of Free Bets to use on in-play markets
• £20 worth of Free Bets to use on Accas with at least 4 selections 
• £10 worth of Free Spins to use on the hit slot Fishin’ Frenzy. This is comprised of 50 Free Spins worth 20p each. 

Deposit Match Bonuses

Deposit Match Bonuses are a type of betting promotion where a bookmaker matches the amount of your initial deposit with a bonus of the same value, up to a specified limit. 10Bet matches your initial deposit by 100% up to £50, with a minimum deposit of £10 and an 8x wagering requirement within 60 days. Use the promo code “SPORT” when registering.

Early Payout Offers

An early payout offer, also known as an “early settlement offer,” is a type of promotion offered by many bookmakers where your bet is paid out as a winner before the event you have wagered on is officially concluded, under specific conditions. Bet365, for example, is one of the top bookies in the UK that provides an “Early Payout” if your football team goes 2-0 up, paying out your bet as a winner regardless of the final outcome. This bonus also extends to NFL games where your team goes 17+ points ahead.

Bet Builders

Bet builders allow punters to create their own bets by combining different markets within the same event. Unibet’s Uniboost lets bettors enhance their winnings through bet builders, while Betway and SBK offer tools for compiling selections, perfect for both pre-game and in-play betting.

Acca Boosts

Accumulator boosts are perfect for those who love multi-bet slips. 10bet, for instance, boosts winnings by up to 100% for accas with 15 or more selections, with potential winnings up to £5,000. This type of offer significantly increases the potential payout on larger bets.

Price Boosts and Super Boosts

Enhanced odds offers, such as price boosts and super boosts, are available at Unibet and Betway. Unibet frequently offers massive odds boosts on selected horse races, while Betway provides odds boosts on a wide range of markets to enhance prices and betting value.

Refer a Friend

Some bookmakers reward players for bringing in new customers. Unibet, for example, offers bonuses up to £150 for referrals, split into increments and subject to wagering requirements. This increases the user base and rewards existing members for their loyalty.

In-play Betting

In-play betting has revolutionised online sports betting, allowing players to bet on football, hockey, tennis and other events as they happen in real life. Many UK betting sites, such as BetVictor, are noted for their innovative approach to live betting, with dynamic graphics and diverse markets that keep players engaged through real-time action.

Loyalty Clubs

Loyalty programs reward long-term players. BetVictor’s Loyalty Club offers up to £25 in free bets without wagering requirements, usable on single or multiple smaller bets. This kind of promotion incentivises frequent play and enhances customer satisfaction.

Price Comparison Features

SBK offers a Price+ feature, which compares odds across several bookmakers to ensure bettors can secure the best odds, leading to potentially bigger wins. This feature is particularly valuable for savvy bettors looking to maximize returns.

Special Competitions

BetVictor hosts the Predictor competition for something unique, appealing particularly to football fans. Participants can win substantial free bets or even a share of a £50,000 prize pool, adding an exciting layer to the traditional betting experience.

What are free bets and how do they work in UK betting?

Free bets are promotional offers provided by UK bookmakers such as Bet365 and William Hill. They allow you to place a bet without using your own money. For instance, Bet365 offers “Deposit £5-10, Bet £10, Get £30 in free bets” with the promo code 365GMBLR. If your bet wins, you receive the winnings minus the stake amount.

How can I claim a welcome bonus at a UK bookmaker?

How do UK betting promo codes work?

UK betting promo codes are special codes provided by bookmakers like SBK. You enter the promo code during registration or deposit to activate special offers. For example, SBK offers “Bet £10, Get £10 in free bets plus additional tokens” using the sign-up code BRITISHG30.

What are the best long shot bets available in the UK betting market?

Long shot bets are higher risk but can offer significant rewards. For example, SpreadEx offers “Bet £10, Get £40 in free bets and spreads” with a requirement to bet at odds of no less than 1:2, giving an opportunity for higher potential returns.

What is the best way to find UK betting offers for major events like the Premier League?

The best way to find UK betting offers for events like the Premier League is to check the promotions sections of top bookmakers such as Bet365 and Ladbrokes. They often have enhanced odds and free bet offers for major matches.

Can existing customers get free bets from UK bookmakers?

Yes, UK bookmakers like Unibet and BetVictor frequently offer free bets to existing customers through loyalty programs and special promotions. For example, Unibet provides a “Bet loses, Get up to £40 back plus £10 casino bonus” offer.

What are the wagering requirements for bonus bets in UK betting?

Wagering requirements specify how many times you must bet the bonus amount before you can withdraw any winnings. For instance, 10Bet offers a “100% deposit match up to £50” with a requirement to wager the deposit and bonus 8 times within 60 days using the deposit code SPORT.

Are there any free bet clubs available for regular bettors in the UK?

Yes, several UK bookmakers offer free bet clubs for regular bettors. For example, Betway’s Free Bet Club rewards customers with £10 in free bets if they place £25 on trebles or accumulators each week.

How do I use promo codes to get the best UK betting offers?

To use promo codes, enter the code during the sign-up or deposit process on the bookmaker’s website.
