Stepping up from the standard £30 welcome, a Bet £10 Get £40 offer gives you a 400% return on your qualifying stake. Most £40 promotions ask for a slightly higher minimum odds (often Evens / 2.0) in return for the bigger free bet pot.

Read full talkSPORT BET review →In my two decades of betting on sports every single day, I've learned that maximizing your bankroll is just as important as picking winners. While the industry standard welcome bonus gives you a 300% return, there is a tier of elite offers that pushes that value even higher. Welcome to the "Bet £10 Get £40" club.
Offering a massive 400% return on your initial qualifying stake, these promotions are among the most generous you will find in the UK market. If you are looking to build a serious betting portfolio, claiming these specific offers is the smartest first step you can take. Below, I break down how they work, the traps to avoid, and the absolute best bookmakers currently running this premium promotion.
The mechanics are straightforward, but the value is immense. You open a new account, make a £10 deposit, and place a £10 real-money wager on a qualifying sports market. Once that initial bet settles, the bookmaker rewards you with £40 in free bets.
Rarely is this credited as a single £40 lump sum. Usually, bookmakers split this into smaller, strategic tokens — for example, four £10 free bets. Frequently, they will allocate these tokens to specific bet types to get you to explore their platform (e.g., £10 for an accumulator, £10 for a Bet Builder, £10 for horse racing, and a £10 generic free bet). As always with free bets , the "Stake Not Returned" (SNR) rule applies: you keep the winnings, but not the free bet stake itself.
Not all bookmakers are willing to hand over 400% in bonus value. Having personally tested the platforms, deposited my own cash, and withdrawn the winnings, here are the top UK operators currently offering the stellar Bet £10 Get £40 promotion.
The gold standard for this specific offer right now. BetMGM has aggressively entered the UK market and they are using this massive welcome bonus to grab attention. Their £40 is typically split into highly usable £10 segments (like a £10 horse racing bet, a £10 Bet Builder, a £10 football bet, and a £10 acca). Their app is elite, and their odds pricing is incredibly competitive.
The kings of betting entertainment, Paddy Power rarely disappoints when it comes to value. Their Bet £10 Get £40 offer is a staple during major sporting events or the start of the football season. What I love about Paddy Power is their user-friendly interface and the fact that their free bets often come with very fair, transparent terms and conditions.
A giant in Ireland with a massive and highly respected UK presence. BoyleSports is a fantastic traditional bookmaker, especially if you love horse racing and football. Their Bet £10 Get £40 offer is a brilliant way to test out their excellent daily promotions, such as early payouts and extra place races.
If you want something genuinely different, Kwiff is the place to be. They are famous for "Kwiffing" your bets — randomly supercharging your odds to massive prices after you place your wager. Adding a £40 free bet package on top of a platform that might randomly triple your payout makes this one of the most exciting accounts you can open.
A highly established, trusted name in the global betting industry. Betway's platform is incredibly deep, covering everything from Premier League football to niche esports. Their Bet £10 Get £40 offer is robust and reliable, often bundled with straightforward qualifying terms that make it easy for new punters to unlock.
Originally famous for being Europe's biggest Daily Fantasy Sports (DFS) platform, Fanteam has successfully launched a brilliant traditional sportsbook. Because they are still growing their sportsbook audience in the UK, they are offering an incredibly generous Bet £10 Get £40 bonus to win over traditional punters. It's a great interface and well worth adding to your betting arsenal.
Bookies aren't in the business of giving money away to people who break the rules. After 20 years of doing this, I still follow this exact checklist every time I claim a new bonus to ensure I never miss a payout:
Before you use your £40 bonus, always check these three things in the T&Cs:
A 400% return is the sweet spot of welcome offers. It provides enough ammunition to try out multiple bet types — singles, builders, and accas — without requiring a large upfront deposit. I highly recommend opening accounts with BetMGM and Paddy Power first to secure their world-class platforms, before working your way through the excellent value offered by Kwiff, BoyleSports, Betway, and Fanteam. Grab the value while it's available.
