To ensure you take advantage of bankroll-boosting bonuses and betting promotions, we are constantly looking for the most exciting free bet offers from the top UK bookies.

UK betting promos include welcome offers, reload bonuses, money back specials, cashback offers and free spins. Let’s take a closer look at these types of betting offers and explain how they work and how you can best use them.

888sport betting offers

Welcome Offers

This is a bonus directed at potential new customers, so is often the most lucrative on offer from an online casino or bookmaker. Most new customer welcome bonuses are matched to a certain percentage of your initial deposit and in many cases. your opening deposit is doubled, trebled or more. Casino welcome offers almost always come with rollover requirements but sports betting welcome offers usually have no wagering requirements. In many cases you can only choose one welcome bonus when joining a new betting site. Always read and understand all the key terms of a welcome bonus before accepting.

Reload / Deposit Bonuses

A deposit or reload bonus is similar to a welcome bonus in that your deposit amount is matched to a percentage. Many online casinos in UK will provide you with regular reload bonuses, possibly even on a daily basis. However, they are not as large as your first welcome bonus, and they will, like all promotions, be subject to numerous terms and limitations. These types of bonuses are more associated with casino deposits than sports betting.

Odds Boosts

In sports betting and odds boost is, as the name suggests, an increase to the normal odds of some sporting outcome. Most online sportsbooks include odds boosts in the daily offers but certain bookies sometimes offer really big odds boosts which are definitely worth considering. For example, bet365 have their ‘Super Boost’ offers with sometimes dramatically increased odds. Maximum stakes are limited but will vary for each customer in the range of £10 to around. £40. William Hill also occasionally release an ‘Epic Boost’ where you could back Manchester City to win at Evens instead of say, 2/7! These super boost offers usually come with a maximum stake to £10. Betfair Sportsbook is another good site to check for odds boosts.

Money Back Specials

A money back special is a betting promotion that has some built in insurance where your stake is returned if a certain condition is met. For example, Boylesports will give you your money back as a free bet (up to £25 max) if your horse finishes 2nd to the SP favourite. Paddy Power is the self-proclaimed ‘Home of the money back special’ and always has plenty of these promotions on offer. Your stakes are usually refunded in the form of free bet credits rather than actual cash.

Cashback Offers

Cashback betting offers, also known as cashback promotions, are a type of bonus or incentive provided by online betting sites to their customers. These offers are designed to provide a certain percentage of the bettor’s losses back to them as a cash refund or free bet credit. The concept behind cashback offers is to give bettors a second chance or a safety net in case their bets don’t result in a win.

Free Spins

When you play at online casinos, you can earn free spins as a promotional offer. Simply put, you are given a set amount of free spins to utilise on a specific slot machine. They are available as no deposit bonus or as part of deposit bonus packages. Although this appears to be too good to be true, it is a popular marketing strategy used by most online casinos to recruit new consumers. Furthermore, these bonuses are available at numerous $1 minimum deposit casino sites, allowing you to test the waters without putting too much money at risk. There is no catch to this offer; whatever you win when playing with free spins is yours to keep.


There are always lots of competitions to get involved in such as prize draws, prediction games, slots tournaments, fantasy sports games and freeroll poker tournaments where you can win big. Always keep an eye on their bookmaker’s Promotions pages for any good ones and remember, you’ve got to be in it to win it!
