Free bets are the most advertised thing in British betting. Almost every bookmaker offers them to new customers, and many offer them to existing customers too. They can be a genuinely nice extra. They can also be confusing, because the word "free" hides a set of conditions that are not always obvious. This guide explains how free bets really work, how to read the terms and how to tell a good offer from a poor one. For our wider recommendations, see the main guide to the best betting sites.
What is a free bet?
A free bet is a bet the bookmaker pays for. You choose a selection, use the free bet as your stake and, if your selection wins, you receive the winnings. The key difference from a normal bet is what happens to the stake. With a normal bet, you get your stake back when you win. With most free bets, you do not.
- Stake not returned phrase
- Often written as SNR. It means that when a free bet wins, you get the winnings but not the value of the free bet itself.
Worked example. You place a £10 free bet at 3/1. It wins. A normal £10 bet would return £40, which is £30 winnings plus your £10 stake. The free bet returns £30, because the £10 stake was the bookmaker's, not yours.
This is why a £10 free bet is worth less than £10 in cash. How much less depends on the odds you use it at. At short odds you get very little. At longer odds you could win more, but you are also less likely to win at all.
Free bets are also sometimes called bonus bets or free bet tokens. Whatever the name, the principle is the same: you are betting the bookmaker's money, and the terms decide how and when you can use it.
How welcome offers work
The most common welcome offer in Britain is a "bet and get" deal. You open an account, deposit, and place a first bet of a set amount at or above minimum odds. Once that bet has settled, win or lose, the bookmaker credits your account with free bets. A typical example might be "bet £10, get £30 in free bets", though the amounts vary.
The qualifying bet
The first bet you place is called the qualifying bet. It must meet the offer's conditions to trigger the free bets. The most common conditions are a minimum stake, minimum odds and a time limit for placing it after you register. If your qualifying bet does not meet the conditions, you will not receive the free bets, even if it wins.
Opting in
Some bookmakers ask you to tick a box or enter a promo code when you register. Others apply the offer automatically. If an opt-in is needed and you miss it, you may not be able to claim the offer later, so read the sign-up page carefully.
Deposit requirements
Most welcome offers require you to deposit before you can claim them, usually at least the amount of the qualifying bet. There are occasional no-deposit offers, but they are rare in the British sports betting market and usually small.
The 2026 rule changes
The Gambling Commission introduced new rules on promotions from 19 January 2026. Two changes matter most for free bets. First, any wagering requirement, meaning the amount you must bet before bonus money can be withdrawn, is capped at ten times the bonus. Second, offers can no longer mix different types of gambling. A betting offer must be a betting offer only, without casino spins or bingo tickets bundled in.
For most sports bettors, these rules have made offers simpler. Traditional free bet offers, where winnings are paid as cash, have never usually had wagering requirements. Where a bookmaker does attach conditions to winnings, those conditions are now limited.
Good to know. Licensed bookmakers must show the main conditions of an offer clearly, close to where the offer is advertised. If you cannot find them easily, that is a warning sign in itself.
Reading the terms without getting lost
Offer terms can run to many paragraphs, but the important parts are usually in a short section called the significant terms. These are the conditions that make the biggest difference to whether the offer is worth having. Here is what to look for.
Minimum odds
Most offers require the qualifying bet, and sometimes the free bets, to be placed at minimum odds, often evens or slightly shorter. This stops customers using offers on near-certainties. Check the minimum carefully, because a bet at 4/5 will not count if the offer requires evens or bigger.
Expiry dates
Free bets do not last forever. Most expire within seven days of being credited, although some last longer. If you do not use them in time, they disappear. Make a note of the expiry date when you receive them.
Market restrictions
Some free bets can only be used on certain sports or bet types, such as football accumulators or horse racing singles. Others can be used on anything. A restricted free bet is less flexible and therefore worth a little less.
Payment method exclusions
A few bookmakers exclude certain e-wallets from welcome offers. If you plan to pay with PayPal or another e-wallet, check that it counts before making your first deposit.
Splitting free bets
Some offers give you one large free bet. Others split it into smaller amounts, such as three free bets of £10 each, sometimes with each one restricted to a different type of bet. Smaller split free bets give you more chances to win something, but each one is worth less.
Keep a simple note of any offer you claim, with the date, the qualifying bet and the expiry date of the free bets. It takes a moment and stops you missing a deadline or forgetting which account has free bets waiting.
Types of free bet
Not every free bet works in the same way. Knowing the main types helps you compare offers properly.
Standard free bets
The most common kind. You get a set amount to bet with, and winnings are paid as cash, minus the stake.
Money-back offers
These refund your stake as a free bet if your bet loses in a particular way. A common example is money back if your horse finishes second, or if your first goalscorer scores later in the match. They only pay out in specific situations, so they are worth less than an outright free bet.
Acca insurance
This refunds your stake, usually as a free bet, if one leg of an accumulator loses and all the others win. Look at the minimum number of legs, the minimum odds for each and the maximum refund.
Bet credits
Some bookmakers call free bets "bet credits". They work in much the same way, but the terms can differ slightly, particularly on how winnings are paid. Read the terms to see whether the stake is returned.
Free bet clubs
Some bookmakers run clubs where you receive a free bet each week if you place a certain number of qualifying bets. They can be good value if they match your normal betting. If you find yourself placing extra bets just to earn the reward, the club is costing you more than it gives.
How much is a free bet really worth?
A useful rule of thumb is that a standard free bet is worth between half and three-quarters of its face value, depending on the odds you use it at. A £30 offer is not the same as £30 in your bank account. It is still worth having, but it should not be the main reason you choose a bookmaker.
Worked example. You have a £10 free bet. At odds of 1/2, a win returns only £5. At odds of 4/1, a win returns £40, but it is much less likely to happen. Either way, the average value over many bets is less than £10.
Offers with fewer restrictions, longer expiry dates and low minimum odds are worth more than those with many conditions. A smaller offer with simple terms can be better than a larger offer with complicated ones.
Using free bets wisely
Because the stake is not returned, many people use free bets at slightly longer odds than they normally would, perhaps around evens to 3/1. That tends to give a fair balance between the chance of winning and the size of the return. There is no rule, though, and it is sensible to use a free bet on something you would genuinely be happy to back with your own money.
Before accepting any ongoing promotion, read its terms as carefully as you read the welcome offer. Existing customer promotions often have their own minimum odds, qualifying periods and expiry dates, and they can change from week to week.
Free bets for existing customers
Once the welcome offer has been used, many bookmakers keep offering promotions. These might be weekly free bets for placing a certain number of bets, loyalty rewards, price boosts or money-back specials on big events. They are a sign that a bookmaker values its regular customers.
Be a little careful with them. Promotions that require you to bet a set amount each week to earn a reward can encourage you to bet more than you planned. If a promotion would make you bet when you otherwise would not, it is not really a reward.
It is also worth remembering that the bookmaker chooses which customers receive promotions. Two people with accounts at the same site may see different offers. That is normal and not a sign that anything is wrong with your account.
Common free bet mistakes
The most common mistake is not reading the terms at all and then being disappointed. Others include placing the qualifying bet at odds that are too short, forgetting to opt in, letting free bets expire, and using a payment method that is excluded from the offer.
A quieter mistake is choosing a bookmaker only for its offer. The welcome offer is used once, but you may use the account for years. A site with good everyday prices, reliable withdrawals and a clear app will serve you better in the long run than one with a big offer and little else.
- Promo code noun
- A short word or code you enter when signing up or depositing, to claim a particular offer. Not every offer needs one.
What if I change my mind?
If you decide not to use an offer, you do not have to. You can simply let free bets expire, or ask customer service to remove the offer from your account. Declining an offer does not affect your ability to deposit, bet or withdraw your own money.
Choosing a good offer
When comparing offers, ask four questions. How much do I need to bet to qualify? What are the minimum odds? How long do I have to use the free bets? And are there restrictions on how I use them? The offer with the simplest answers is usually the best value, even if the headline amount is smaller.
Then look past the offer to the bookmaker itself. Check that it is licensed, that its app is easy to use and that it offers the sports you actually follow. If those boxes are ticked, the offer is a pleasant bonus on top of a good account.
Finally, never deposit more than you planned just to unlock a bigger offer. If an offer needs a larger qualifying bet than you are comfortable with, it is simply not the right offer for you, and there will always be others.
Keeping free bets fun
Free bets are designed to get you betting, and they work. That is fine, as long as you stay within the budget you set. Set a deposit limit when you open the account, before you claim any offer. If you notice that promotions are pulling you into betting more than you intended, it is worth turning off marketing emails and app notifications in your account settings. You can switch them back on at any time.
Common questions
Do you get your stake back with a free bet?
Usually not. Most free bets are stake not returned, so a winning £10 free bet at 3/1 pays £30 rather than £40.
What is a qualifying bet?
It is the first bet you place to trigger a welcome offer. It must meet the offer's conditions, such as a minimum stake and minimum odds.
How long do free bets last?
Most expire within seven days of being credited, though some last longer. Check the expiry date in the offer terms.
What changed for free bets in 2026?
From 19 January 2026, wagering requirements are capped at ten times the bonus and betting offers cannot be combined with casino or other gambling products.
