Best betting sites offers: welcome & sign-up bonuses for new customers in the UK, August 2026

What are sports betting bonuses

Put simply, a welcome bonus in the UK is an extra benefit offered by the operator to new users. Usually, this offer doubles the balance of your first deposit, gives you a free bet and even gives you free spins just for registering your account.

In addition to sports betting bonuses, we also review the best casino bonuses, in case you also enjoy gambling.

Types of bookmaker offers

There are various types of bookies sign up offers in the UK iGaming industry. But what are the most popular bonuses?

Sign-up offers & welcome bonuses

• Some UK bookmakers’ new-customer deals include sportsbook sign-up offers that double your initial deposit up to a certain percentage (usually 100%). Others, however, will refund the full amount of your first losing bet, although this is not as common among bookmakers’ offers for new users.

No deposit bonuses

• With these, you don’t need to make an initial deposit; you simply need to register on a betting website to receive a free bonus, such as a free bet or betting credit to use on any of the available sports and events. This isn’t very common for new users, as most free bets linked to an initial deposit offered by UK operators require you to make an initial deposit.

Free bets

• Free bets allow you to place a bet without risking any additional funds; however, you must meet certain requirements. For example, Betvictor offers £30 in free bets when you deposit and bet £10 at odds of 2.00 or higher within seven days of registering.

Deposit match bonuses

• With deposit match bonuses, the operator matches all or part of the player’s first deposit. For example, a 100 per cent bonus up to £100 turns a £50 deposit into a starting balance of £100. However, we recommend that you read the wagering requirements.

Reload bonuses

• These online betting bonuses reward players with an additional percentage of their extra deposits. They are almost always aimed at registered users and, on most betting sites, are usually activated once a week. To withdraw the bonus, you must meet a specific rollover requirement, amongst other conditions.

Cashback bonuses

• With cashback bookmaker bonuses, the operator returns a percentage of your net losses (in some cases, 100%) from your first play. The refund is usually credited to your balance or given as free spins so you can play again.

Exclusive bonuses for VIP players

• This only applies to casinos that offer a VIP club or loyalty programme. Here, the more you play, the more points you’ll earn or the higher the levels you’ll reach, allowing you to access exclusive offers, free spins, discounts, personalised 24/7 support and higher withdrawal limits.

Best betting site promotions for specific sports

In the UK, football is the most popular sport, but other events such as horse racing and cricket are also hugely popular. Let’s take a look at the promotional offers available from betting companies for these sports:

Football

Online sports betting promotions for football offer the widest variety amongst UK bookmakers. You can find free bets for the Premier League, Champions League and FA Cup, as well as enhanced odds, early payouts and refunds if a team squanders a lead. These offers are usually available before and during matches, for both single and accumulator bets.

Horse racing

Horse racing, meanwhile, occupies a prominent place in the UK market. Bookmakers offer risk-free bets, enhanced odds, extended place payouts and refunds if a horse finishes second or falls at the final fence, particularly at events such as Cheltenham, Royal Ascot and the Grand National.

Cricket

It’s no secret that cricket is one of the UK’s most popular sports, so sportsbooks offer exclusive bonuses and promotions, including free bets, enhanced odds and early payouts when a team reaches certain milestones. Naturally, during competitions such as The Hundred, the T20 Blast or international series, huge volumes of bets are placed.

Other popular sports in the UK

As well as the sports mentioned above, betting sites that give a bonus also run promotions for rugby, tennis, darts, snooker, golf and Formula 1. Odds boosts and insurance on accumulator bets stand out from the rest.

How to claim betting bonus codes

Take note of the following list to ensure you enter the promotional code correctly:

1. Choose a licensed bookmaker: Check that the operator is regulated in the UK and that the promotion is available to new customers.
2. Register an account: Complete the registration process using your real details and verify your identity if necessary.
3. Enter the bonus code: Enter the online bookie promo code during registration or in the deposits section, if the offer requires it.
4. Make a deposit: Deposit at least the minimum amount specified in the promotion terms.
5. Meet the wagering requirements: Place the qualifying bet in accordance with the minimum odds and eligible markets.
6. Receive the bonus: Once the requirements have been met, the free bets or deposit bonus will be credited automatically or within a specified timeframe.
7. Check the terms and conditions: Check the bonus validity period, wagering requirements (rollover), market restrictions and any winnings limits before using the promotion.

Tips for choosing the best bookies bonuses

When choosing the best sportsbook bonuses, it’s important to bear in mind that absolutely all of them have terms and conditions, and that these vary.

Depending on the terms of each bonus and your preferences, we recommend choosing one option over another.

Bonuses with very high minimum odds are not the best option for those who do not like accumulator bets, whilst other terms and conditions, such as restricted payment methods, may be key factors in deciding whether or not it is worth taking the bonus.

How to use bookies offers in the UK

To make the most of bookmakers’ offers in the UK, you must first register with a licensed operator and read the promotion terms and conditions carefully. Check the minimum deposit, the required odds, the eligible markets and the bonus expiry date before placing any bets.

Once the promotion has been activated, use the free bets or deposit bonus on events that meet the set conditions. Keep track of the wagering requirements (rollover), ensure offers do not expire, and check any withdrawal restrictions to maximise the value of each available promotion.

Why trust BetBrothers?

How we rate

Our experts carefully evaluate the bonuses based on various criteria. The first thing they check is whether the bookmaker holds a UKGC licence and what security measures are in place on the site (SSL encryption, two-factor authentication, identity verification, etc.). For us, reputation is everything.

Next, we analyse in detail the value of the bonus, the wagering requirements, the accepted payment methods and the clarity of the terms and conditions. The aim is to provide you with as much information as possible so that you have no doubts when claiming and using the promotion.

Bonus terms and conditions

As with any casino bonus or promotion, there are requirements you must meet to claim it. These may vary depending on the complexity of the offer, but generally you will need to:

1. Make a minimum deposit (each casino sets its own)
2. Check the rollover requirement (the number of times you must wager the bonus to withdraw your winnings)
3. Check the timeframe the casino gives you to meet all the bonus conditions.
