Free bets are one of the most common welcome offers from UK bookmakers — and one of the most misunderstood. This guide explains exactly how free bets work, what the terms mean, and how to get the most value from them.
Key Facts
- Free bets let you place a bet without risking your own money — if it wins, you keep the profit
- The free bet stake is never returned — you receive profit only, not stake plus profit
- You must place a qualifying bet with real money first before the free bet credits to your account
- Risk free bets return your qualifying stake as a free bet if your qualifying bet loses
- Free bets expire — most last between 7 and 30 days, so always check the expiry date
- Casino Compare rates every free bet offer for difficulty, risk and estimated value at casinocompare.uk
What is a free bet?
A free bet is a promotional token that lets you place a bet without risking your own money. If the bet wins, you keep the profit. If it loses, you lose nothing — the bookmaker absorbs the cost. Furthermore, free bets are almost always offered as part of a welcome package for new customers, making them one of the most accessible ways to try a new bookmaker without financial risk.
In practice, free bets work like this: you sign up, place a qualifying bet with your own money, and the bookmaker credits your account with a free bet token once that qualifying bet settles. You then use the token to place a second bet — the free bet itself.
Do I keep the free bet stake?
No — and this is the most important thing to understand. When a free bet wins, you receive the profit only. The stake does not come back to you.
For example, if you place a £30 free bet on an outcome at 2/1 odds and it wins, you receive £60 in profit — not £90. The £30 stake is not included in the payout. This is standard across all UK bookmakers and appears in betting terms as “stake not returned” or SNR.
What is a qualifying bet?
A qualifying bet is the bet you must place with your own money before the bookmaker releases your free bet. Most qualifying bets carry minimum odds requirements — typically evens (2.0) or above. Furthermore, some bookmakers restrict which markets or bet types count as a qualifying bet, so always check the terms before placing it.
The qualifying bet itself is a normal real money bet — it wins or loses as usual. As a result, the outcome of the qualifying bet does not affect whether you receive the free bet. As long as you meet the minimum odds and stake requirements, the free bet credits to your account after the qualifying bet settles.
How long do free bets last?
Most free bets expire within 7 to 30 days of being credited to your account. If you do not use the free bet before the expiry date, it disappears from your account without any return. Always check the expiry date as soon as your free bet credits and plan your bet accordingly. Furthermore, some bookmakers split free bets into multiple smaller tokens rather than one lump sum — check how yours will be credited before you start.
Can I withdraw a free bet?
No — you cannot withdraw a free bet token. You can only use it to place a bet. However, any winnings from a free bet are real cash and you can withdraw them immediately in most cases, subject to any additional terms the bookmaker applies.
What is a risk free bet?
A risk free bet is a variation of the standard free bet offer. Instead of receiving a free bet regardless of the qualifying bet outcome, a risk free bet returns your qualifying stake as a free bet only if your qualifying bet loses.
For example, a £20 risk free bet means: place a £20 qualifying bet, and if it loses, you get £20 back as a free bet token. If your qualifying bet wins, you keep the winnings and receive no free bet. As a result, risk free offers carry no financial downside beyond the original stake — which is why Casino Compare rates them as Risk Free in our difficulty system.

What affects the value of a free bet?
The main factors that determine how much a free bet is actually worth are:
Odds — higher odds on your free bet produce bigger potential returns. A £30 free bet placed at 5/1 returns £150 in profit. However, the same token placed at evens returns only £30. Choosing the right odds for your free bet makes a significant difference to the outcome.
Stake not returned — since the stake never comes back, the true value of a free bet is always less than its face value. A £30 free bet at evens is worth £30 in profit — not £60. In other words, always factor this in when calculating expected value.
Expiry date — a free bet that expires in 7 days is harder to use effectively than one lasting 30 days, particularly if you are waiting for a specific event or market.
Market restrictions — some bookmakers restrict which markets you can use your free bet on. In-play markets, each-way bets, or certain sports may be excluded. Always check the terms before placing your free bet.
How does a free bet differ from a deposit bonus?
A free bet and a deposit bonus are both welcome offers but they work very differently. A free bet gives you a token to place one bet with — there are no wagering requirements on the token itself, only on any winnings in some cases. Furthermore, free bets are sports betting offers, whereas deposit bonuses are almost exclusively casino offers.
A deposit bonus matches a percentage of your deposit as bonus funds — for example, a 100% match on £50 gives you £50 in bonus funds. However, you must then wager those funds a set number of times before withdrawing. Under the new UKGC wagering cap introduced in January 2026, all UK casino bonuses are capped at 10x wagering.

Frequently Asked Questions
Can I use a free bet on any market?
Not always. Most bookmakers restrict which markets qualify for free bets. In-play betting, each-way bets, and certain sports are commonly excluded. Furthermore, some offers require you to use the free bet on a market with minimum odds. Always check the specific terms attached to your free bet token before placing it.
What happens if my free bet pushes or is void?
If your free bet is placed on a market that results in a void or push — for example, a postponed match — most bookmakers return the free bet token to your account so you can use it again. However, this varies between operators. Check the terms for your specific offer.
Can I claim a free bet more than once?
No — welcome free bet offers are for new customers only and each bookmaker allows you to claim them once per person. However, existing customers can often access reload free bets and ongoing promotions through the bookmaker’s promotions page. These are usually smaller but available on a regular basis.
Do free bets count towards wagering requirements?
Free bets on sportsbooks do not typically carry wagering requirements in the traditional casino sense — they are one-time use tokens. However, some bookmakers do require winnings from free bets to meet minimum odds before withdrawal. Always check the specific terms of your offer.
What is the difference between a free bet and a bonus bet?
The terms are used interchangeably by most UK bookmakers. Both refer to a token that lets you place a bet without risking your own money, with the stake not returned on winning bets. Some operators use “bonus bet” to distinguish promotional tokens from standard free bets earned through loyalty schemes — but the mechanics are the same.
Are free bets available to existing customers?
Yes — most major UK bookmakers offer ongoing free bet promotions to existing customers through their promotions pages. These include acca insurance, price boosts, reload offers and weekly free bets. Furthermore, some bookmakers offer loyalty-based free bet schemes where regular bettors earn tokens based on their wagering activity.
What if I forget to use my free bet before it expires?
If your free bet expires unused, it is removed from your account automatically and cannot be reinstated. As a result, always set a reminder as soon as a free bet credits to your account, particularly if the expiry window is short. Most bookmakers do not extend free bet expiry dates under any circumstances.
Summary
Free bets are one of the most valuable and accessible welcome offers available from UK bookmakers. In short, you place a qualifying bet with your own money, the bookmaker credits a free bet token to your account, and you use that token to place a second bet at no personal risk.
The most important things to remember are that the stake is never returned on a winning free bet, free bets expire, and some markets may be restricted. Risk free bets go one step further — returning your qualifying stake as a free bet if your first bet loses, making them the lowest risk entry point for new sports bettors.
