What are betting promotions?

Betting promotions are offers from bookmakers designed to give existing and new customers extra value on top of their normal bets. They include free bets, odds boosts, acca insurance, cashback deals and loyalty rewards, and they run alongside a bookmaker's regular odds rather than replacing them.

What's the difference between betting site promotions and app promotions?

Most UK bookmakers run the same promotions across their website and app, but some offers, like app-only odds boosts or push notification deals, are exclusive to the app. Always check the terms on the specific platform you're using, since an offer visible on desktop isn't guaranteed to show in the app and vice versa.

How do I compare betting promotions?

Look past the headline offer and compare the wagering requirements, minimum odds, qualifying bet size, expiry window and whether winnings pay out in cash or bonus funds. A smaller offer with fair terms is often worth more than a bigger one with restrictive conditions.

What is a wagering requirement?

A wagering requirement is the number of times you need to bet through a bonus (or your winnings from one) before you can withdraw it as cash. For example, a 3x wagering requirement on a £10 bonus means you need to stake £30 in total before withdrawal.

What does "minimum odds" mean on a promotion?

Minimum odds are the lowest price a bet must be at to qualify for a promotion, commonly 1/2. Betting below that price means the promotion won't apply, even if the bet itself wins.

What happens when a betting promotion expires?

Each promotion has an expiry window, often 7 to 30 days, stated in its terms. If you don't use a free bet or complete the wagering requirement within that window, the bonus is void and any unused funds are removed from your account.
