New Casumo Sign Up Offer for Autumn 2026: 100% Back Up to £30 as a Free Bet

September 18, 2026

It’s easy to assume that Casumo doesn’t have something exciting going on when you are just looking at their homepage. However, when you dig much deeper, there’s actually a generous Casumo sign up offer waiting for new customers.

The good news is that you won’t have to spend ages searching around to find it because we’ve already done the hard work for you. Below, we’ll break down exactly what the new Casumo sign-up offer is and how you can claim it because that’s something you would want for this autumn’s packed sports schedule.

What is the new Casumo sign up offer?

More often than not, Casumo is not always mentioned among the best UK betting sites, but it should be considered for how easy it is to claim its sign-up offer. All you have to do is register for a Casumo account and bet at least £5 on an acca with three legs or more. If it loses, you can unlock a 100% refund of as much as £30 in bonus bets.

We actually tried it for ourselves during the most recent Manchester derby between the Red Devils and the Citizens when we had an acca of Erling Haaland to score, City to win, and Both Teams to Score. Obviously, our acca lost because United failed to score, but we didn’t walk away completely empty-handed because our bet met the requirements of the Casumo welcome offer.

Speaking of requirements, it is worth mentioning that the odds on each leg of your acca should be at least 1.40 but not exceed 6.00 to qualify for the bonus. The best part in all of this is you won’t need a Casumo promo code to take part in the offer, so you can skip the usual hassle of searching the internet for a code that may or may not even work.

Key terms and conditions for Casumo’s new sign up offer

Although we’ve pretty much covered everything about Casumo’s latest sign up offer, there are still a few important details you should know before you jump in. Similar to UK betting promotions you’ve probably seen before, this offer comes with specific terms and conditions that say who can claim it and how you can use your bonus. To make things a lot easier, we’ve outlined everything in the table below.

It is, however, important that we mention that these terms and conditions are not set in stone, so make sure to always check Casumo’s terms and conditions page for any changes.
