For example – some betting sites have plenty of sports, but only a handful of ways to bet on them – poor market selection. Or.. some have high wagering requirements, which means you likely won't keep much profit from your welcome bonus. It is our duty to inform you of such caveats, so you always make an educated choice! Existing customer bonuses are just as important in our quest to provide you with the most value. Livestreaming, clean website design, intuitive navigation and responsive customer support are all things that come to mind, when talking about the bookie.

Betfair has been a very popular and respected bookmaker for over two decades.

There’s no downside to taking the bonus if the terms are reasonable. Which betting sites offer the best free bets? All the bookmakers we’ve reviewed on this page offer free bet welcome bonuses. The best value offers give you between £30-£50 in free bets or bet credits from just a £10 stake.

Since its inception in 2009, BookiesBonuses's sole purpose has been to help punters find the best betting sites for their needs. The bookie hosts both a regular sportsbook and a betting exchange, making it a versatile and valuable tool for any punter. I like the variety of football betting markets, and the plethora of payment methods with low deposit limits. Betfred is an age-old bookmaker with tonnes of experience in the UK market. They're well-known for their football and horse racing markets and promotions, and are ideal for most punters' needs. While some variety in the promotions department wouldn't hurt, Betfred absolutely is a solid choice of a betting site. Sky Bet is a powerhouse when it comes to livestreaming licenses, sponsorships and everything in between.

Terms and Conditions of Free Bet Offers

Every bookmaker featured holds a valid UK Gambling Commission license, ensuring your funds are protected and you’re betting at legitimate, regulated sites. Do I need a promo code to claim welcome offers? Some sites require you to enter a bonus code when you deposit, while most activate your bonus automatically after your first deposit. We always mention in our reviews whether a code is needed, so you’ll know before you sign up. Why are some bet types excluded from bonuses?

Betway summary

Bookmakers restrict certain bet types to limit their risk on bonus funds. For example, with a £30 free bet, if you could split it into multiple £1 bets across different markets, you’d have 30 chances to win something. By requiring you to use it as a single £30 stake, they’re giving you just one chance at a return. Other common restrictions include excluding accumulator bets or requiring minimum odds of evens or higher. These rules reduce the likelihood of you securing guaranteed profit from bonus funds.

Do I need to make a deposit to get a free bet?

The best approach is to wait for a market with good odds on an outcome you’re confident about before using restricted bonuses. Do I have to use the welcome bonus? If you don’t claim it or use it within the validity period (usually 7-30 days), it simply expires. You can continue betting normally without ever activating the bonus. That said, we recommend claiming it even if you only deposit the minimum amount – getting matched funds or free bets from a small deposit is still free value. I would recommend Sky Bet to punters looking for livestreaming and in-play betting on horse racing, football, basketball and boxing. Sky have really put their best foot forward when it comes to market variety and competitive odds. Their promotions are nothing to sniff at either, especially their AccaFreeze feature.

With time they realized there was no service for an easy comparison of welcome offers online. Initially, the site was really just a product for themselves and their friends, aggregating the offers in order to compare.
