Free £25 Bet Online Bookmakers

All the betting sites featured on this page offer new customers who sign up, deposit, and wager for the first time a free £25 bet credit.

As of 2025, very few online bookmakers in the UK offer a £25 free bet. Bookmakers are always changing their welcome offers to suit market conditions and see which ones best attract newcomers to betting online.

However, it seems the £25 free bet bonus has fallen out of favour. But no worries—there are many other configurations of free bets on offer. Take a look at the list of free bets below for inspiration and plenty of free bet options.

How to Claim the £25 Free Bets?

Let's take the Casuno Sports 50% Cashback up to £25 as an example of how to claim.

You get 50% back on your very first bet up to £25.

The main stipulation is that the first bet you place has to be a real-money accumulator. Obviously, if it wins, the free bet won't apply; however, if it loses, you will get the £25 free bet, giving you another chance.

So, How does it work:

1. Open your Casumo and head to the Sports section.
2. Place your cash accumulator bet of £2 or bigger (has to be a minimum of legs 3, minimum odds of 3.00).
3. If you win, your bet will be paid out as a winner, and you’ll forfeit your £25 free bet Welcome Offer.
4. If you lose, you’ll be credited with a free bet to the value of 50% of your original stake – up to £25.
5. Your Free Bet will be automatically activated in your bet slip (min odd 2.0, valid for seven days).
6. If your Free Bet wins, all winnings will be paid out in cash minus the stake.

Example:

Step 1: Place a cash acca bet of £20. If the bet loses, you’ll be credited £10 (50% of £10) as a 1x Free Bet.
Step 2: You place your free bet of £10 at odds of 4.0. If it wins, you will receive your winnings minus the stake. So £30 cash (£10 x 4.0) – £10)
