Free bets are the most common betting promotion in the UK, but the name can be misleading. A free bet is a token with conditions, not cash. This guide explains the four terms that most affect what a free bet is actually worth: stake not returned, minimum odds, expiry and wagering requirements.

How do free bets work? The short answer
A free bet is a bet token a bookmaker gives you, usually after you place a qualifying bet with your own money. If the free bet wins you keep the winnings, but the token’s stake isn’t paid back, so a £10 free bet that wins at evens returns £10, not £20. Most tokens also have minimum odds, an expiry date and rules on which bets they can be used for.
This is how that looks on four welcome offers we checked on the bookmakers’ own pages on 21 October 2026:
| Bookmaker | You stake first | Free bets you get | What they can be used on | They expire |
|---|---|---|---|---|
| Sky Bet | A 5p+ first bet at 1/1+, after a £5 deposit | 3 × £10 | Singles and each-way bets (not virtuals) | 30 days after crediting |
| Midnite (code BETGET30) | £10 at 1/1+ | £10 + 3 × £5 + £5 | £10 single at 1/1+; three pre-match bet builders at 3/1+ with 3+ selections; one pre-match acca at 4/1+ with 4+ selections | 7 days after crediting |
| Stakemate | £10 at 1/1+ | 4 × £5 | Bets with 3+ selections at total odds of 3.0+ | Date shown on each token |
| Dabble (code B10G10) | A £10+ single | £10 | Not stated in the key terms | 7 days after crediting |
18+. New customers only. These are the significant terms as published by each bookmaker on 21 October 2026; the full terms are on the bookmaker’s site and can change, so read them before you opt in. BeGambleAware.org
None of these returns the free bet stake. Excluded deposit methods: Neteller and Skrill at Sky Bet, Revolut at Stakemate.
What is a free bet?
A free bet is a credit that lets you place a bet without using your cash balance for the stake. You usually receive it after placing a qualifying bet with your own money, or as part of a promotion for existing customers. You cannot normally withdraw the token itself. If the bet it’s used on wins, you receive winnings that may then be withdrawn, subject to the bookmaker’s terms and verification checks.
1. Is the free bet stake returned?
With a normal cash bet, a winning bet returns your winnings plus your original stake. With most free bets, the stake is not returned. You only receive the winnings.
Worked example (illustration only):
| Cash bet | Free bet (stake not returned) | |
|---|---|---|
| Stake | £10 cash | £10 token |
| Odds | 3.0 (2/1) | 3.0 (2/1) |
| Total return if it wins | £30 | £20 |
| Of which winnings | £20 | £20 |
| Of which stake returned | £10 | £0 |
This is why a £10 free bet is worth less than £10 in cash. At low odds, the difference is significant: a £10 token at 1.5 (1/2) would return only £5 if it won.
Some bookmakers word this as “SNR” (stake not returned). Occasionally, a promotion returns the stake; the terms will say so if it does.
2. What minimum odds apply?
Many offers require that both the qualifying bet and the free bet are placed at or above a minimum price, for example evens (2.0 or 1/1). Bets below the minimum may not qualify, and a token may not be usable on short-priced selections.
Why it matters:
- Higher odds mean a lower chance of winning. A token that must be used at higher odds is more likely to lose.
- Combined odds may count. For accumulators, the minimum may apply to each leg, to the whole bet, or both.
- Odds can move. If the price drifts below the minimum between selection and placement, the bet may not count.
Reading odds formats
- Decimal: total return per £1 staked, including stake. 3.0 means £3 back for every £1 on a winning cash bet.
- Fractional: winnings relative to stake. 2/1 means £2 winnings per £1 staked, plus the stake on a cash bet.
3. When do free bets expire?
Free bets usually expire after a set period, which can range from a day or two to several weeks depending on the operator. Unused tokens are removed. Expiry can apply in two ways:
- Claim window: how long you have to place the qualifying bet after registering or opting in.
- Use window: how long you have to use tokens after they are credited.
If you don’t expect to bet within the window, the offer may be worth nothing to you. Don’t feel pressured to bet just because a token is about to expire – letting it lapse costs you nothing.
4. Do free bets have wagering requirements?
A wagering requirement means winnings (or a bonus amount) must be staked a set number of times before they can be withdrawn. For example, with a 5x requirement on £20 of winnings, you would need to place £100 of bets before withdrawing.
Points to know:
- Many UK sports free bets have no wagering on winnings, but some do. Always check.
- Wagering is more common with casino-style bonuses.
- Only some bets may count towards wagering, and at different rates.
- Rules have tightened. Since 19 January 2026, wagering requirements on bonuses are capped at a maximum of 10 times. (Source: Gambling Commission, LCCP SR Code 5.1.1, in force 19 January 2026.)
Wagering requirements can encourage you to bet far more than you intended. If an offer has them, consider whether you would place those bets anyway.
Other terms worth knowing
- Qualifying bet: the bet you place with your own money to trigger a promotion. It must meet stated conditions.
- Eligible markets: tokens may be limited to particular sports, competitions or bet types.
- Excluded bet types: each-way, cashed-out, system or virtual bets are common exclusions.
- Payment method exclusions: some deposit methods may not qualify.
- Maximum winnings: some promotions cap what you can win.
- One per customer: offers are usually limited to one per person, household, device or payment method.
- Verification: you must pass age and identity checks before gambling and before withdrawing.
A quick checklist
Before claiming any free bet, ask:
- How much of my own money must I stake first?
- What are the minimum odds?
- Is the stake returned?
- When does it expire?
- Are there wagering requirements?
- Are my preferred payment method and sport eligible?
- Can I afford the qualifying bet if it loses?
If you can’t find clear answers on the bookmaker’s site, think twice. Our step-by-step guide to claiming a free bet shows where each of these terms usually appears.
How much is a free bet actually worth?
A free bet is worth less than its face value, because the stake isn’t returned and the bet can lose. If it wins, you receive the winnings only. The table shows what a £10 free bet returns if it wins at different odds, next to a £10 cash bet.
| Odds | £10 cash bet returns | £10 free bet returns |
|---|---|---|
| 1/2 (1.5) | £15 | £5 |
| Evens (2.0) | £20 | £10 |
| 2/1 (3.0) | £30 | £20 |
| 5/1 (6.0) | £60 | £50 |
Longer odds keep more of the token’s face value if the bet wins, but they win less often. There is no way to make a free bet into guaranteed money: it is a bet, and it can lose like any other. Tokens that must be used on several selections are even less likely to win; see how accumulator odds multiply and how bet builder free bets work.
Do you need to deposit to get a free bet?
Almost always, yes. The UK welcome offers we check ask you to deposit and place a qualifying bet with your own money first. Genuine no-deposit free bets are rare. Our no deposit free bets guide covers the exceptions, including free-to-play games such as Sky Bet Super 6, which costs nothing to enter.
Keeping free bets in perspective
Promotions are marketing. Their purpose is to bring in new customers and keep existing ones betting. It’s perfectly reasonable to ignore them. If you use them, set a deposit limit first and stick to a budget you’d be comfortable spending on any other form of entertainment.

Frequently asked questions
Why is a free bet worth less than its face value?
Because the stake isn’t returned and the bet may lose. You only get winnings, and only if it wins.
Can I split a free bet?
Sometimes. Some tokens must be used in full on a single bet.
Can I cash out a free bet?
Some bookmakers allow it, many don’t. Check the terms.
Can you withdraw a free bet? No. The token itself can’t be withdrawn: Sky Bet and Midnite both describe their welcome free bets as non-withdrawable. If a free bet wins, the winnings (without the stake) can usually be withdrawn, subject to the bookmaker’s terms and identity checks.
Can you use a free bet on an each-way bet? It depends on the offer. Sky Bet’s welcome free bets can be used on singles or each-way bets, while Midnite’s can’t be used on each-way bets. Check the terms of each token.
Are free bet winnings taxed in the UK? No. Gambling winnings aren’t taxed for the player in the UK, and that includes winnings from free bets. See our guide to betting tax in the UK.
