How to Claim Betting Offers

Claiming your bonus is uncomplicated. The process is roughly the same, regardless of which bookie you choose to join. However, there may be some variations that you need to understand. For example, some online bookies will award the bonus upon making your first deposit, while others may require you to redeem a promo code.

Step-By-Step Instructions for New Customers

We have put together a quick guide to explain how to claim your bonus in a few easy steps. Bookmakers typically make the process as simple as possible, so you can start betting on your favourite sports without delay.

The Bonus Conditions

The most overlooked factor when comparing the best betting offers is the bonus requirements. As a result, we often advise bettors to read the terms and conditions carefully to avoid confusion. In general, you will need to clear the wagering requirements to convert bonus funds to withdrawable cash. Failure to comply may result in bonus funds being voided.

When it comes to sports betting bonuses, the number one detail to look out for is the so-called rollover requirement. In other words, how many times does the bonus need to be wagered before a withdrawal is possible? Some bookmakers extend the rollover requirement to your starting balance, while others may only consider the bonus awarded.

At the same time, a rollover requirement of 3x your starting balance (deposit + bonus) with a 100% match bonus is identical to a rollover requirement of 6x the bonus. We have added three models below as an example:

100% up to £150 bonus with 6x rollover:

200% up to £50 bonus with 4x rollover:

50% up to £100 bonus with 3x rollover:

In addition, bookies will place an odds restriction on bonuses. In our experience, these vary between 2/5 and 1/1, while some bets may not count towards the rollover beyond a certain threshold. Often, this means you won’t be able to place wagers on the outright favourite again and again to clear bonus conditions.

You should furthermore pay attention to which bets are allowed. Do odds restrictions only apply to individual bets, or do they apply to combined bets as a whole? In most cases, system bets (a combination of several accumulator bets) are excluded unless each individual line bet meets the specified betting odds requirements.

Another factor to consider is the time limit allowed to clear bonus conditions. Rushing your bets for the sake of the rollover requirements is one of the quickest ways to deplete your balance. We, therefore, recommend checking how much you would need to wager per day or week and whether the validity period makes sense.

Meanwhile, some markets may be excluded from betting offers. Online bookmakers may additionally limit the maximum amount you can win. Usually, this means that you will only be allowed to cash out winnings up to a certain amount over and above your bonus. Depending on the bookmaker, this could result in a portion of your winnings being voided.

Finally, you should check whether you are receiving a ‘real bonus’ or promo cash. The difference: with a real bonus, you can convert the bonus amount to withdrawable winnings by clearing the wagering requirements. With promo cash, the bonus amount is deducted. Thus, you will only be allowed to cash out actual winnings.

Types of Betting Offers for New Players

Once you have wagered your welcome bonus, you can start participating in a wide range of promotions for existing customers, from weekly reload bonuses to free bets for popular markets, such as those at our recommended football betting sites. We will introduce you to the main promotions from UK bookmakers below.

Free Bets

Free bets are highly sought-after and can best be described as a token from the bookie. If you receive a free bet, you can wager on virtually any sport, so long as you meet the minimum odds requirements. Meanwhile, if your free bet concludes in a win, you will only receive the profit from your wager and not the free bet amount.

For example: If you place a wager worth £10 at +100 odds, your payout will only include your profit of £10, not £20 (£10 stake + £10 profit). It’s worth noting that while some bookmakers impose wagering requirements on winnings from free bets, others don’t.

Match Deposit Bonuses

Matched betting offers are promotional incentives provided by bookmakers to attract and retain customers. These offers reward bonus funds in return for a qualifying deposit amount. The value of the match deposit bonus varies significantly, depending on the bookie.

Enhanced Odds

Enhanced odds are special price boosts bookmakers offer on selected matches and events. They’re temporary upgrades to normal betting prices, giving you better returns if you win. These boosted prices typically appear for popular events or to attract interest. Just be aware that they don’t last long—bookies limit them by time or until a certain amount is wagered.

Betting Offers for Existing Customers

Odds Boosts

Odds boosts are promotions that provide higher potential payouts for the same amount of risk. Bookmakers will periodically increase the odds for selected markets, making it possible to win more money than you would have otherwise. Depending on the online bookmaker, odds boost promotions will usually increase the odds between 10 and 40 percent.

In addition to odds boost promotions, several bookmakers (most notably cricket betting sites) will offer profit boosts. The main difference is that odds boosts are often limited to specific markets, while profit boosts are available on any game within a market. Also, a profit boost can increase your profit if a wager settles in your favour.

Accumulator Bonus

The accumulator bonus, makes it possible to combine betting on various markets in a single wager. Usually, the same stake is placed on three or more outcomes with a bonus of around 5%. However, the longer the accumulator bet, the higher the bonus. Bear in mind that your combined bonus is calculated by winning all the events on your bet slip and may be limited to specific markets.

Accumulator Insurance

The accumulator insurance, is almost the opposite. It protects you against losses when placing wagers. The insurance option is usually available for 5-way combo bets or more. If you only have one loss on your betting slip, you will get your stake back in full, either as bonus credit (with subsequent wagering requirements) or as a free bet.

Early Bet Settlements

Bookmaker promotions include the ability to settle your bets early. Usually, this happens when the team you are backing gains an advantage, such as a 2-goal lead or in online tennis betting. Once a bet is settled, the rest of the game becomes irrelevant. The bookie will often payout your winnings immediately.

We only consider legitimate offers from licensed bookies – the rest is all about how much value the punter can get out of the deal and how fair the surrounding conditions are.

Frequently Asked Questions

Our guide covers many topics about what to consider when comparing the best betting offers. If you need additional information on the subject, continue reading the FAQs below. These include links back to the most relevant content on this page.

1️⃣ Which online bookmakers have the best betting offers?

2️⃣️ Is there a no deposit sports betting bonus?

While rare, there are bookmakers in the UK where new customers can start betting with no deposit bonuses. Most of the time, you will receive free bets or free cash to spend on selected markets. It’s worth noting that you cannot withdraw your no deposit bonus without clearing the wagering requirements first.

3️⃣ Which criteria are important for bonus comparisons?

When assessing bonuses from online bookies, some of the most important criteria are the rollover factor, the minimum odds, and whether your bonus comes with specific limitations. For example, some bookmakers exclude payment methods like PayPal, Neteller, and Skrill from sign-up offers. You can find more details in our section about wagering requirements.

4️⃣ Am I obliged to accept a betting bonus from the online bookmaker?

No, you are not obliged to accept any offers. Most promotions have terms and conditions that require you to meet the wagering requirements before you may withdraw any winnings. Declining a bonus means you won’t have to fulfil these requirements. However, it also means you won’t receive bonus money or free bets. This statement applies to new and existing customer promotions.

5️⃣ Do I need a promo code to activate my bonus?

No, not unless the bookie asks you to redeem a promo code. Usually, you can activate your bonus by navigating to the cashier and making your first deposit. Our guide includes instructions on how to claim your bonus in a few easy steps.

6️⃣ What offers are available for mobile betting?

The new customer bonuses and regular promotions are available on mobile as well. Almost all online bookmakers in the UK have mobile apps these days, which allow you to claim bonus offers from virtually anywhere. You can additionally use your mobile device to access all your favourite local and international betting markets.
