The 2025 Grosvenor sports sign up offer provides new customers with a unique double-the-odds boost on their first £10 sports bet, plus 100 free spins for the casino. I’ll walk you through the offer details and how to claim it below.
What is the Grosvenor Sports sign up offer in 2025?
The Grosvenor sign up offer for sports provides a 100% odds boost on your first qualifying bet. The offer is valid for 60 days, allowing new customers a full two months to place the first qualifying bet. Any winnings you receive from this offer will be paid out in cash.
Here's a real-life scenario to illustrate precisely how this offer works. Let's say you place a bet on Chelsea to beat Manchester City. The odds for backing Chelsea are 2.00, and the stake is £10. After you apply the odds boost token, you'll get odds of 4.00 instead of 2.00.
Winning scenario example: If Chelsea wins, the returns will be £40 rather than £20 that you'd initially get. If you don't come with the full stake of £10 and only wager £8, for example, the £2 cannot be claimed back in the next bet. It will be forfeited as the odds boost token is applicable only once for a new player.
Losing scenario example: There are no stake refunds if Chelsea does not win the game. The entire £10 would be forfeited.
Grosvenor caps the maximum amount converted from bonus to cash at £200.

Grosvenor Sports offers for existing customers
After claiming your sign-up bonus, Grosvenor offers ongoing promotions for existing customers. Let’s look at the current ones below:
Odds Boosts
Grosvenor offers several odds boosts, notably on football matches. This means that if you win your bet, your payout is enhanced. It’s is a great way to increase your bet’s value and add to the thrill.
Fantasy 5 at Grosvenor
Something that, even as a member, you might not be aware of at Grosvenor is their Fantasy 5 game. This is a great tool for punters to use to get more out of their account. Here’s how Fantasy 5 works:
- Go to the promotions section and look for Fantasy 5
- Opt in to the promotion – it is not automatic
When you opt in, keep these main terms and conditions in mind before opting in:
- A qualifying bet of at least £10 at odds of 1/1 (2.0) or greater is needed
- Void and cashed out bets cannot be used to qualify for this promo
- Single bets and straight line multiple bets only quality. No each-way or perms
- £30 in Free Bet tokens are applied upon the settling of the qualifying bet.
- Free bets come as 3 x £10 bets
- Use the Free Bet option which becomes available on your get slip when the offer is live
- Free Bet can be used on any sport, but no stake is returned
- Each Free Bet to be used in its entirety, not shared across numerous bets
Compared with other bookmakers’ offers, we found these terms very fair. The promo is easy to understand and offers straight-up free bets once you’ve made your deposit and qualifying bet.
Remember to use your Free Bet tokens wisely. Stick to the sports, you know, and you can bet on any of them with your free bets.
In-Play Cash Back
If you’re an NBA fan, there is an in-play cash-back option. The promo, including the playoffs, is ongoing during the 2024/25 NBA season.
Key terms for taking part:
- Opt-in required
- Play on the NBA then have 10% of your cumulative weekly losses returned as cash
- Real money stakes at odds of 1/2 (1.5) or bigger only to count
- Cash refund is credited before 23:59 each Wednesday
Best Odds Guaranteed
The Grosvenor Best Odds Guaranteed (‘BOG’) feature is offered for all UK, Irish and US horse racing events. This feature is great for those who place a bet after 9 am on the race day and the odds change. Grosvenor pays out at the higher odds if the starting price is greater.
For example, if you back a horse at 3/1 and it goes off at an SP of 9/2, Grosvenor pays you out at 9/2. Here are the key terms to remember:
- Available only after 9 am on race day
- Applies to singles and multiples
- Maximum bonus £25,000
Top features on Grosvenor Sports in 2025
Grosvenor Sports is becoming one of the best football betting sites in the UK. Here’s why.
Competitive betting markets & odds
There are more than 40 sports to bet on at Grosvenor Sports, which is among the largest in the UK sports betting fraternity. Most options concern football in horse racing bets, but many less popular sports are also covered on this platform. A punter can even choose to bet on non-sports markets.
Punters should have no trouble getting their hands on several markets simultaneously. The sporting events, especially the European leagues, have been covered in great detail.
In horse racing, the top events like the Cheltenham Festival and Grand National are not to be missed, and Grosvenor Sports offers excellent odds during these events.
Live streaming & in-play betting
Another highlight of Grosvenor Sports is its high-quality live streaming and in-play betting. The live-streaming section possesses a wide variety of sports, including horse racing. So long as you have at least £1 in your account, you can watch horse racing live and place bets in real-time as the game unfolds. For example, you can bet on who will score the next goal in a football match.
Convenient Grosvenor app
The Grosvenor mobile experience is among the best in the industry for casino games. However, it’s important to keep in mind that the app works best on iOS devices. It does have some stability issues for Android devices. The app tends to lock up and crash, sometimes leading you to a blank screen as you attempt to open a page.
With that said, the app offers almost every desktop feature, including live streaming. The Grosvenor sign-up offer is available via the app for iOS and Android platforms.
On the Google Play Store, the mobile app has a low rating (2.7/5). Users complained about the app’s performance issues. However, on the Apple App Store, the app has a good average rating (4.2/5). This difference could be due to the fact that Android OS runs on low-end devices that may not be powerful enough to support the app’s processing demands.
Comparing Grosvenor's welcome offer to the competition
Grosvenor’s welcome offer provides a double-the-odds boost on your first sports bet plus 50 free spins, making it a unique incentive compared to its competitors. Here’s how it stacks up against Coral and Star Sports Bet:
| Details | Grosvenor | Coral | Star Sports Bet |
| Welcome offer | Double-the-odds boost on your first sports bet plus 50 free spins | Bet £10, get £40 in free bets | Up to £25 Free Bet + 25 Free Spins |
| Minimum stake | £10 | £10 | £10 |
| Bonus restrictions | Bonus can be used on any sport | Bonus can be used on any sport | Only for basketball, racing, darts, and football |
| Odds requirements | No odds restrictions | Odds must be 1/2 or higher | Odds of Evens (2.0) or greater |
| Winnings | Winnings credited as odds boost tokens | Cannot be redeemed for cash | Winnings are paid in credits |
The Grosvenor sign up offer stands out with a double-the-odds boost on your first sports bet plus 50 free spins, making it more flexible than both the Coral sign up offer and the Star Sports sign up offer. Grosvenor’s promotion focuses on boosting potential winnings rather than just awarding free bets.
Another key advantage is that Grosvenor has no odds restrictions, meaning bettors can place their qualifying bet at any odds they choose, unlike Coral, which requires odds of 1/2 (1.50) or higher, and Star Sports Bet, which mandates Evens (2.0) or greater.
Regarding winnings, Grosvenor credits them as odds boost tokens, while Coral’s free bet winnings cannot be cashed out, and Star Sports Bet pays them as credits. All three bookmakers offer mobile compatibility, but Grosvenor’s app is available on iPhone, iPad, and Android without additional activation steps. For those seeking maximum betting flexibility and the potential for higher payouts, Grosvenor’s offer is a strong choice.
Grosvenor Customer Support
As a Grosvenor mobile app user, you only need to find the support section from the main menu to access the customer support options. From here, you should be able to search for your support query. You can also access the live chat service, which was available 24/7.
However, while the live chat customer support option is available 24/7, it can often take time to get through to an agent. Wait times are hard to predict as they largely depend on the number of users requiring customer support.
I used the live chat service to speak with an agent regarding a bet settlement issue during testing. I wanted to know roughly how long it would take (roughly) for my bet to settle.
The agent was helpful, and I didn’t have to wait long. The timing of this request was likely in my favour, as it was in the middle of the day during the week. Users should expect longer wait times if using the live chat service on evenings and weekends.
Recap: My take on signing up with this Grosvenor welcome offer
In conclusion, I found that the Grosvenor Sports welcome offer is a great deal. It gave me a lot of flexibility to bet on anything I wanted. Being able to take home 100% of the winnings in cash was a big plus.
Grosvenor also impressed me with its low wagering requirements, especially on the casino welcome bonus. The brand has many facets, such as an impressive array of games, betting markets, and more. I’d definitely give it a go.
