Best free bets and betting sign-up offers for March 2025

You’ve come to the right place.

Thankfully, we’ve done the research so you don’t have to.

To help, we've listed these by the value of free bet you get per £1 deposited (eg, bet £10 get £50 = 5x), any restrictions on which sports you can use these bets on and then the minimum odds required to unlock them.

All of the offers listed have a wagering requirement of just 1x too, which is exactly what you want as a punter and we've explained why further down in this piece.

A closer look at our top free bet picks

After scouring the market we present you with the 10 hottest free bet bonuses in the UK right now:

1. Spreadex

• 3 x £10 free fixed odds bet
• 3 x £5 free Total Goals football spread bet
• 3 x £5 racing Winning Favourites spread bet
• £1 racing Race Index spread bet

Key takeaways

2. Coral

We were worried when we found out that Coral limits the amount of money you can win from free bet bonuses. That fear soon subsided when we read through the T&Cs and discovered that the limit is £1 million.

The chances you’ll win more than that from a free bet are slim. The chances you’ll be unhappy if you win £1 million rather than £1.5 million are even lower.

You can’t claim the welcome bonus if you use an eWallet or prepaid card for your first deposit. All other methods are fair game, which is great because the fact that you get four free £5 bets for a low investment of £5 is fantastic. This makes it possible to spread your risk and, potentially, give yourself a better shot at winning cash prizes, while not risking too much.

Key takeaways

• Four £5 bets
• Can’t use eWallets or prepaid cards
• Low minimum odds requirement

3. SBK

SBK might not be a household name like Coral et al., but it’s become a leading light in the online gambling space due to its commitment to added value. This penchant for promotions is evident in the free bet welcome bonus.

• £10 football Bet Builder token (credited instantly after your initial wager is settled)
• £10 acca token (credited instantly after your initial wager is settled)
• £5 horse racing acca token (credited instantly after your initial wager is settled)
• £5 football Bet Builder (credited 24 hours after your initial wager is settled)
• £10 free bet token (credited 24 hours after your initial wager is settled)

These offers allow you to experience a variety of bets, which is great. They’re also a nice complement to SBK’s legendary Price+ boosts. The only problem with SBK’s offer is that the FAQ states that the minimum odds are 1/2 (1.5) rather than 1/1 (2.0), which is the current minimum odds.

Key takeaways

• Must use a debit card or bank transfer
• Most varied free bet bonus
• No cap on winnings

4. BetMGM

BetMGM might be originally from the US, but it’s embraced British trends and established itself in the UK market. The welcome bonus proves this because you get £10 to bet on football and £10 to bet on horse racing. The remaining £20 is credited as two Bet Builder tokens, which is great if you’re a fan of high-risk, high-reward wagers.

In our experience, Bet Builders are even more attractive at BetMGM because the average line (aka the odds) is better than the industry average. The only issue with this offer is the fact that your initial bet can’t be on eSports or non-UK/IE horse racing events.

Key takeaways

5. Tote

Key takeaways

• Qualifying bet on any sport or racing (if each-way, then minimum bet is £10 win and £10 place)
• Specialized for racing
• 50 Free Spins on Big Bass Bonanza without wagering requirements are part of the bonus

5. BetVictor

• £10 acca free bet (must contain at least four picks for any sports market
• £10 Bet Builder free bet for any football market
• £10 in-play free bet for any sports market (credited 24 hours after your qualifying bet is settled)
• £10 free bet for any football market (credited 24 hours after your qualifying bet is settled)

The £10,000 cap on free bet winnings is a bit disappointing, given that other UK bookmakers don’t limit your potential. That being said, £10,000 is a lot of money, and you’ll have four chances to hit that target.

Key takeaways

• Great free bet offer for football fans
• £10,000 cap on bonus wins
• Qualifying bet must be on a football match

6. bet365

Unfortunately, PayPal and prepaid cards, including PaysafeCard, are excluded from the list of valid deposit methods. However, this is a small downside to bet365's promo which has plenty of upsides for small-stakes sports bettors.

Key takeaways

• Low minimum deposit
• Plenty of time to use bonus
• Reputable operator

7. CopyBet

This promo has some terms and conditions that we don’t like, but they aren’t enough to sour an otherwise sweet deal. It’s a sweet deal because the amount of bonus credit you get is exceptional.

The win cap of £500 should be a lot higher. However, CopyBet has a unique feature that allows you to mirror the moves of experienced sports bettors, which could give you an edge in your next wager.

Key takeaways

• £20 racing bet, £20 live football bet, £20 in-play bet
• First deposit must be via the Open Banking app
• £500 win cap

8. Kwiff

Kwiff’s welcome bonus might not be unique, but it’s easy to claim and packed with value. The three bets you receive are valid for football, racing, and accumulators.

The acca portion of the bonus is most interesting for me because it has the biggest payout potential given that there isn’t a cap on the amount you can win.

As generous as the welcome bonus is, it’s lacking some sparkle. Thankfully, Kwiff dusts its sportsbook with a plethora of ongoing offers. For those familiar with Kwiff, you’ll know it’s the home of supercharged odds boosts.

Key takeaways

• £10 football bet, £10 racing bet, £10 acca (minimum of four selections)
• Each-way wagers are excluded from the qualifying bet
• Nice selection of regular promotions

9. Betway

Betway is also a gambling industry veteran, so you know it’s a safe place to claim free bet credit. Finally, once you’ve claimed the welcome bonus, you can become a member of the Betway Free Bet Club. This club gets you a £10 free bet every week when you wager £25 on trebles or accas with four or more picks.

Key takeaways

• Simple offer
• Plenty of daily odds boosts
• Weekly Free Bet Club

Don’t worry, the T&Cs aren’t overly restrictive. Free bet bonuses represent excellent value, which is why savvy sports bettors claim them whenever possible. That being said, the potential of these offers can quickly evaporate if you don’t understand how they work.

What’s less clear is that you need to make a “qualifying bet”;. In this case, a qualifying bet is any wager that has odds of 1/5 or greater. Expressed in a different way, you won’t get a bonus if your first real-money bet has lower odds than 1/5.

What can I wager free bet bonuses on?

Very few sportsbooks have better football odds than BetVictor, so we don’t mind the welcome bonus restricting you to football bets. In general, though, promos that allow you to speculate on sports of your choosing are better.

Research = real rewards

Our job is to make you a better bettor. The only way to do that is to arm you with as much information as possible. When it comes to free bet bonuses, information is what you need.

Read the T&Cs so you know how to get an offer and, importantly, how it compares to other promos. Be diligent in your research, and the rewards will follow.

How we evaluate free bet offers

Every free bet offer is different. Even though many of the best bonuses look similar on first inspection, they all have their pros and cons.

The terms we evaluate are:

That’s everything you need to know about free bet bonuses, where to find the best offers and the wagering requirements to watch out for. The only thing left to do is walk you through the collection process.

No, you need to wait for your initial wager to be settled before free bet bonuses are credited to your account. There may be a delay of up to 48 hours from the point your initial wager is settled to bonuses being available to use. However, in most cases, bonus credit will be available immediately once the wagering requirements have been met.
