Bet365's 25% Bet Builder boost is a powerful promotion that can significantly enhance your winnings when betting on football matches. By using this offer strategically, you can increase your profits without raising your stake. Whether you're new to matched betting or a seasoned bettor, understanding how to make the most of this offer can help you unlock extra value on your bets. In this guide, we'll break down exactly how the Bet365 Bet Builder boost works, how you can take advantage of it with matched betting, and share tips on how to maximise your profit.
The Bet365 Bet Builder boost gives you an extra 25% on your Bet Builder winnings. This boost applies without needing to increase your stake, making it a risk-free way to enhance your returns.
To qualify for the Bet Builder boost:
Important: The offer is available only once per eligible game and will appear at least 24 hours before kick-off. There's also a maximum stake limit, and the boost is typically a fixed percentage (usually 25%).
Using the Bet365 Bet Builder boost is simple once you know the steps. Follow this process:
The boost applies a 25% increase on the profit part of your bet. Importantly, the boost is not applied to the stake; only your winnings are increased.
The Formula:
The boosted winnings are calculated using this formula:
((Original odds - 1) × 1.25) + 1
This means that your winnings are multiplied by 1.25, increasing your return without increasing the risk.
Let’s say you're placing a Bet Builder bet on the Arsenal vs Bayern Munich match. Your selections are:
These selections predict a 2-0 win for Arsenal — a result that fits both the over 1.5 and under 2.5 markets. Your combined odds for this Bet Builder are 8.00.
Without the boost, your winnings would be calculated as:
Stake × 8.00
Now, let’s apply the 25% Bet Builder boost:
((8.00 - 1) × 1.25) + 1 = 9.75
So, instead of being paid out at 8.00, you'll be paid out at 9.75, an increase in winnings thanks to the Bet Builder boost.
Once you’ve placed your Bet Builder with the boost, the next step is laying the bet at a betting exchange to lock in your profit or minimise risk.
If you're using a scoreline prediction in your Bet Builder, like the 2-0 result in the example above, this makes it easier to lay your bet at the exchange. By predicting an exact score (e.g., 2-0), you can lay this exact scoreline on the exchange, ensuring a more accurate match of odds and an easier process.
Alternatively, you can treat the Bet Builder as a value bet if you're confident in your selections and odds. In this case, you would focus on laying the most likely outcomes at the exchange, allowing you to secure a guaranteed profit or break-even outcome no matter what the result is.
There are two main ways to lay your Bet Builder:

If you have a match result selection in your Bet Builder and the team goes two goals up, you may also qualify for an early payout through Bet365’s 2UP offer. However, it’s important to note that this early payout only applies to the match result leg of your Bet Builder. The rest of your selections must still come in for your full Bet Builder to win.
Risk-free Bet Builders are a fantastic way to make money with minimal risk, especially when you apply matched betting techniques. Whether you’re laying the bet using the calculator or creating value bets, these promotions can be a great addition to your matched betting strategy.
By combining these methods with the use of tools like matched betting calculators, oddsmatchers, and free bet trackers, you can consistently generate profit from these offers. Even if your initial Bet Builder loses, your free bet will provide a second chance to secure a risk-free profit.
A risk-free Bet Builder is a bookmaker promotion that allows you to place a Bet Builder bet, and if it loses, you receive a free bet equal to your original stake.
You can make it profitable by either laying the bet using a matched betting calculator or by building a value bet with higher odds, ensuring that even if you lose the free bet, you still make a small profit in the long run.
You can lay a risk-free Bet Builder bet by using a matched betting calculator to calculate the correct lay stake. Once you’ve placed the back bet, lay it at the exchange to lock in a guaranteed profit or minimal loss.
