Best betting offers & free bets for existing customers for 2025

Everyone knows that bookies always reward new players with a welcome bonus, but there are plenty of offers for existing customers out there, and I’m here to help you find the best ones.

An in-depth look at the best free bet offers for existing customers

Free bets are not always easy to come by for existing customers, as most bookies I’ve seen on the UK market prefer to focus on attracting new customers.

Still, that doesn’t mean there aren’t betting apps and sites out there that offer these treats regularly, especially if you know where to look, as I do. I’m here to give you an in-depth look at the best free bets loyal punters can expect right now.

1. bet365

You just know a giant like bet365 knows how to appreciate loyalty, and they’re nothing if not generous to those who stick around. The acca boost I found is most definitely in line with that policy.

I had, as you would, the chance to win up to £100,000 on a successful football acca, with a maximum boost of up to 70% of your winnings. Choose your bets carefully!

2. 10bet

10bet acca boosts

Up to 100% boost on winning accas!

Applies to successful acca bets of 3+ selections; Min odds of 1/2 per selection; Bet exclusions apply; Max £5K; Bonus % depends on bet type; T&C apply; 18+

CLAIM HERE

Since I decided to stay a while at 10bet, I wanted to make the most of their acca boost, and here’s how I did it: I needed to make at least a three-leg acca on any sports market (I went for a five-parter); once it won – and it did – I was rewarded with a 5%-100% cash boost on my winnings.

Of course, the less likely the outcome, the bigger the boost, and only a successful 15-leg acca will land you the full 100% bonus.

if you’re still not sold on becoming a loyal 10bet customer, take a look at my colleague’s in-depth 10bet review – he rated it as one of the safest betting sites.

3. BetUK

BetUK free bets club

BetUK free bets club

Min bet of £15 or more on Horse Racing (Singles and above) at odds per selection 1/1 (2.0) or greater. Promo expires each week, Sunday 23:59. 1 x £3 Free Bet credited on qualifying bet settlement on selected events. 2 claims per customer. Opt-in required. Free bet must be selected via checkbox on Betslip & cannot be withdrawn. 7 day expiry on free bet. Exclusions apply. 18+ BeGambleAware.org. T&Cs apply.

CLAIM HERE

As I guessed from the name, this loyalty club rewards loyal players with consistent free bets every week. And this isn’t the only option I had, either – while the offer above is aimed at horse racing, fans of football bet builders will be happy too, with £10 free bets every week. You’ll be ready for big PL weekend!

You won’t believe it, but I found one more reward club at BetUK – clearly the bookmaker wants people to stay. I could join the acca club too, which would then give me both a free bet and five profit boosts on accas. Truly, no one could every say BetUK doesn’t know how to treat existing bettors.

4. Betway

Betway Free Bet Club

£10 in free bets on trebles and accumulators!

Opt-in required. Single Line Multiples including 3+ selections. Min. overall odds: 2/1. £25+ of real money bets must be settled between Saturday 00:00 GMT and the following Friday 23:5 GMT. 18+ BeGambleAware.org Further terms apply.

CLAIM HERE

It’s not always available, and changes from week to week from what I could tell, but if you manage to catch it (as I did) and opt in for Betway’s excellent free bet club, every three-part acca you make amounting to at least £25 in bets will be rewarded with a £10 free bet. What’s not to like?

5. Unibet

Unibet Money Back special

Get your money back

Selected races only, opt-in in bet slip, max free bet refund £20, min stake £1, offer can’t be used with Uniboost, available on singles only.
18+ www.begambleaware.org Further T&Cs Apply.

CLAIM HERE

I rated Unibet as one of the top football betting sites in my testing for loyal bettor offers, and my colleague’s Unibet sports review and his honest thoughts on the bookie match my judgement pretty exactly.

Racing fans can also make use of Unibet’s specials, as every bet slip offers a chance to get your money back if the horse you bet on doesn’t win, but only just. If the horse places 2nd or 3rd, you’ll get up to £20 back!

Exploring different types of betting offers for existing customers 

Once you’ve registered an account with an online sportsbook and gone past the welcome bonus, it’s time to explore different types of betting offers since you’re now an existing customer. This is when the real journey begins. Below, I’ll introduce you to, and explain, the most common promos you could have access to as a returning player.

Free bets for existing customers

Free bets basically imply the bookie puts up the stake. This means that if you place a free bet, you only get to keep the winnings. Since the betting site is fronting the money there will most likely be terms and conditions attached to what happens with the winnings. Free bets that don’t require a deposit are particularly appealing but not as common.

Money back free bet

This offer is getting more and more popular among bookies. The deal with a money-back free bet is that you often have to place a risky bet, like a preset acca, and if it doesn’t pay out, then you will get your money back as the stake of a free bet or several free bets depending on the specifications. As always, free bets come with their own limitations so be sure to read up on the terms first.

Best odds guaranteed (BOG)

If you come across a market to bet on with the letters BOG on it, then you can rest assured that you’re guaranteed the best odds available applied to your winning bet. Your sportsbook will let you know which other bookies they will compare odds against before you place your bet.

Enhanced odds

Enhanced or boosted odds are applied to certain events chosen by your sportsbook. The bookie will simply inflate the potential payout artificially. kwiff is fast making a name for itself by boosting odds randomly after players have placed their bets to multiply potential winnings with massive multipliers.

Acca insurance

First, you need to know that an acca (short for accumulator) is a bet with multiple outcomes (legs) on the same slip. If only one leg fails, the whole stake is lost. With Acca Insurance, then one leg can fail and you will still get a reward. This offer can vary between bookies. Some might return a portion of your stake as bonus money or you could even get your entire stake back as one or more free bets.

Free-to-play games

In my experience, only the biggest and best betting sites can afford to offer free-to-play games since they normally don’t require a deposit to participate in. A great example is the football predictor competition offered by Unibet.

Reward/loyalty schemes

Loyal players are always asking for special treatment and extra rewards, and rightly so, in my opinion. Some bookies offer automatic membership to their loyalty schemes while others are by invitation only.

What these schemes have in common is a level-up system based on points earned during a certain period (normally a month). Points are earned from wagering and can be exchanged for different kinds of rewards.

Things to look out for with free bets for existing customers

As I always say, all that glitters isn’t gold, just like free bets aren’t always necessarily truly free. Let me walk you through a few things to look out for with free bets once you’ve become an existing customer. Regardless of any offer, you should always read the full terms and conditions before claiming it. These are the most common terms to watch out for:

• Minimum stake
  It’s just what it sounds like. If you bet less than the minimum stake to qualify for the free bet offer, it won’t count. Your bet may still be valid for all other intents and purposes but always double-check your stake before you click to place your bet.
• Minimum odds
  Just like your stake, make sure the odds or combined odds on your bet slip are what’s required from the terms and conditions. This is extra important to check twice when you’re betting on accas with multiple legs.
• Eligible bets
  Sometimes you may be required to bet on pre-match odds and other times only in-play bets count. Also, make sure you’re betting on the right sport, market, tournament, etc. One mistake means that you’re no longer eligible to receive the free bet.
• Maximum winnings
  Bookies are the ones who front the stakes for all free bets so to ensure that they don’t go out of business, winnings from free bets can be capped.
• Expiry date/Validity period
  This is one of the most important items on this list. It would be a shame to receive a free bet and lose it because it expired. The duration for which a free bet is valid can differ greatly depending on the bookie. If the bet is only valid as a live bet for a specific event, make sure you will be available to place your bet.

How to claim existing customer-free bets

After you have registered and logged into your sportsbook, there will be a section in your account where you can find your available rewards.

This is where all free bets end up once you’ve fulfilled all requirements to get them. Simply click the button that allows you to claim it and now it’s ready to be used.

How I rate bookmakers’ existing customer offers

First and foremost, I rate bookmakers’ offers for existing customers based on how transparent the terms and conditions are. If it looks like I need a law degree to figure out the requirements to claim and use an offer, it’s probably not worth my time.

Cash rewards without strings attached are the best ones. What you win you should be allowed to keep.

Lastly, I look at how easy it is to use the reward. For example, if I win a live-free bet on a boxing match that takes place in Australia, it might not be possible for me to actually use it due to the time difference.

Which bookie gives the most free bets?

From my list of bookies up top, it looks like 10bet, BetUK, Betway, and Unibet are giving away the most free bets. William Hill also gets a notable mention.

It all comes down to participating in promotions. Free bets aren’t going to find their way to your rewards section on their own.

Can you withdraw free bets?

You’ll never be allowed to withdraw the stake of a free bet since this is fronted by the bookie. You may however be allowed to withdraw the winnings of your free bet after the stake has been returned. I say “may” because every sportsbook has rules for the minimum withdrawal limit.
