Types of Betting Bonuses in the UK
Betting offers come in various forms and sizes. The leading bookmakers are always looking for new and interesting ways to stand out from the crowd and encourage you to sign up. In this section of our article on bonuses and free bet offers, we cover the most popular options.
Welcome Bonus & Sign Up Offer
Reserved for new customers and available at most bookmakers. Create an account, deposit £10 or more and gamble on sports. You’ll then get your bonus.
Free Bets
Free bet offers are the most sought-after deals. Here are some of the types of betting promotions available before the next big match.
No Deposit Free Bets
Join a bookmaker and get a free bet. There’s no need to deposit and place a qualifying bet. Attractive, but rarely available.
Qualifying Bet Free Bets
The most common of the free bet offers. You must deposit £10 or more using a card and place a bet on sports. When your first wager results, you get the bet credits.
Matched Bet Bonus
Deposit using a debit card, place a bet and get the same amount as a free bet. If you bet £10, for example, you’ll get a £10 free bet.
No Deposit Bonus
A bookmaker may drop a free bet into your account for many reasons, including being a loyal customer or approaching a popular sporting event.
Deposit Bonus
Make regular deposits and bet on sports to release the bonus, such as a free bet. An example is placing 5 x £10 football accumulators and receiving a £10 free bet.
Risk-Free Bet
Gamble on sports, and if your pick wins, you get the profits. If your pick loses, you get your stake back, allowing you to try again.
Enhanced Odds Bonus
Betting traders often boost the odds of popular bets, such as a player scoring first in a derby or the favourite in a horse race, like the Grand National.
Other Promotions for Existing Customers
Here are some more excellent free bet offers and deals for existing players.
Acca (Accumulator) Bonus
Place an accumulator bet on football or sports and get enhanced odds if you land a winner. The more legs in your acca, the higher the boost.
Cashback Bonus
Place an accumulator and get your losing stakes back as a free bet if one leg lets you down.
Loyalty/VIP Bonus
Prove yourself as a loyal customer by placing regular bets and join the loyalty or VIP programme. You’ll receive free bets, enhanced odds, prizes, and more.
Reload Bonus
An example would be a 50% reload bonus on £100. That means when you deposit and gamble £100, you’ll automatically get another £50 in free bet tokens.
Mobile Betting Bonus
Some betting apps offer free bets, enhanced odds and other deals for sportsbook wagers placed on their mobile app.
Money Back Specials
Get your stake back if your horse doesn’t run, your player doesn’t start, your greyhound is beaten in a photo finish and more.
Event-Specific Promotions
Betting apps will often release event-specific promotions, including free bets, on the Cheltenham Festival, UEFA Champions League final, and Grand Slam tennis.
Tips for Choosing the Best Offer for You
- Browse what’s available and read the terms and conditions attached.
- Resist the urge to grab the first free bet you see. Some aren’t as generous as they seem.
- Don’t take a free bet for the sake of it.
- The deal must fit into your budget and match the sport you love most.
- Withdrawing your winnings must be easy.

What Are Promo Codes and How Do They Work?
A promo code is similar to a voucher code, and you must enter it when claiming your welcome bonus. If a promo code is required, it’ll be given during registration.

When you have your free bet, it’s time to put it to good use. Flashscore has everything you need to beat the bookies by making well-informed predictions.
