The Grosvenor Sportsbook Sign-Up Offer
The Grosvenor welcome offer is one of the easiest to claim. Just click on one of the links through this review to be able to get yourself started.
New players can get double the odds on the first bet that they have with Grosvenor, up to a £10 stake. The offer is as straightforward as that. So many new customer offers from bookmakers are filled with minimum prices, maximum stakes, play through amounts that can look difficult from the outside. With Grosvenor, it really is one of the easiest that we have ever done. There is no Grosvenor promo code to enter when you sign up to allow you to take the offer which makes things even easier.
New customers only. Offer applies to Sport bets only. Maximum total stake is £10 (except Paypal). Each way bets are a maximum of £5 each way (£10 total stake). Expire in 60 days.
How to get the Grosvenor Welcome Offer?
The bonus offer from Grosvenor is an interesting one as it is a little different from most of the other offers that are out there. It is both an offer which is an easy one to understand but it is also one that has a process that is simple to follow for you to be able to get the offer. Follow the numbered steps below to get yourself signed up with Grosvenor.
- Sign up for a Grosvenor account using one of the links that you can find on this page.
- No bonus code is required to get your hands on this offer.
- Provide any documents that Grosvenor requests from you as part of the KYC process.
- Make your first deposit of £10 to take maximum advantage of the offer.
- Place a £10 bet (either to win or £5 each way if on the horses) and tick the price boost box that appears on the bet slip.
- The 100% boost token has an expiry of 60 days on it so there is plenty of time.
How to register with Grosvenor?
To register with Grosvenor is easy. We have the path set out in simple steps above but just in case you need a little more help and a deeper understanding of each of those, keep reading and we will dig a little deeper for you.
1) Open your Grosvenor account
Luckily for new customers, Grosvenor is an easy bookmaker to sign up for a new account with. Follow one of the links on this page to go straight to the form that you need to fill in. It is only a short form with very little in the way of questions so it is quick and easy to complete. Ensure that the information you put in is accurate or you will struggle with step two.
2) Verify your account
Most new customers with Grosvenor will not have to verify their account, it will be done automatically as part of the sign-up process. If the bookmaker is not sure about something that you have entered, then you might be asked to send in some documents to prove that you are older than 18 and are who you say you are. A photo and address are normally the required documents when it comes to a KYC check so a passport or driver's licence along with a household bill are the best things to use.
3) Make your first deposit of £10
There are only a few deposit methods when it comes to Grosvenor but even with only a small amount, there should be some form that will suit everyone. Visa and Mastercard are the most prominent pair but you can also add money into your Grosvenor account via Paypal or Paysafecard. You can make a deposit of less than £10 (though not by PayPal) if you wish but a first deposit of £10 allows you to gain the maximum out of the bonus offer.
4) Place a £10 bet on a sport of your choosing
Once your initial deposit has been made, you will then need to place that £10 on any bet that you wish. This is a great part of the Grosvenor sign-up offer, that there are no price restrictions. There is a limit of 60 days with which to use the token which gives you plenty of time to have a good look over the sports that are open to you. It is a fine balance that needs to be struck with the bet. Double the odds on a smaller price to try and get a winner or double the odds on a bigger price and swing for the fences, The choice is entirely up to you.
5) Make sure you tick the 100% Odds Boost box
This is an easy step to miss as it is a different welcome offer from those that most bettors are used to. When you have decided what you want to make as your first bet with Grosvenor and added the selection to your bet slip, you will have to make sure that the 100% Odds Boost box has been ticked so that it applies to your bet. The offer is only valid on the first bet that you make with the account so if you do not tick the box, then the offer will be lost to you.
Grosvenor sign-up terms and conditions
One of the things that new bettors will really appreciate when it comes to joining Grosvenor is just how few terms and conditions there are surrounding the sign-up offer. Fundamentally, you just make your first deposit of £10, place that on the bet of your choice and make sure that you click the 100% bonus button on your bet slip and it is as simple as that.
There is no minimum price to worry about and no playing through any money that you win X number of times over before you are allowed to withdraw. Just do not try and cash out, the bet in question and make sure that you use the full £10 in one hit (£10 win bet or £5 each way) or the offer will be limited to the smaller stake that you have put on with the rest lost.

What to do
- Take your time to fill in the form properly with no spelling mistakes or false info.
- Make sure that you pick the right selection for your boost. You have 60 days after you sign up to use it so there is no rush to make a pick.
- Use the full £10 that you have deposited on the boost bet to take full advantage of the 100% bonus boost.
- If you are asked to verify your identity as part of the sign-up process, check that the documents you send are clear and in focus so that time is not wasted but having to send them again.
What not to do
- Do not try to sign up if you already have an account or someone else on the same IP address as you already do.
- Do not use nicknames or aliases when filling in the welcome form. It will lead to you being checked and if the documents you send in do not match the info that you have put on the site, then your account will be in danger of being closed before it is ever really opened.
- There are not many instructions when it comes to using the bonus boost but do not ignore the few terms and conditions that there are.
- Do not rush into a bet if you are in any way unsure, there are 60 days to play with.
Grosvenor other bonuses
There is one other bonus from Grosvenor that is worth discussing and that is their casino sign-up offer. It should be no surprise to anyone that this is a strong part of their site given that it was in the casino world that Grosvenor is best known.
The Grosvenor casino bonus
This offer is one for those who are more casino-minded but remember you can only take one welcome offer so you can only claim either the casino offer or the sportsbook one. To take advantage of the offer, you need to deposit at least £20 and select the offer in the cashier to take the £30 bonus.
There is a list of games for the online casino that you are not allowed to use the bonus from Grosvenor on so that needs to be looked over carefully. For a full list, check out the FAQs at the bottom of this review.
The combined deposit and bonus need to be wagered 30X before anything can be withdrawn and the maximum winnings that can be gained from this promotion is £2,000. Slot games count for 100% of contributions towards the wagering requirements, live game shows 10% while jackpot and progressive games count as 50%. There are 30 days to fulfil the wagering requirements.
You are also at risk of the welcome offer funds being removed if you use a 'minimal risk' approach to roulette. For those who do not know what that means, it is betting both black and red on a wheel spin to limit losses and try to work through a wagering requirement quicker without taking what would be regarded as normal risks.

The Grosvenor poker bonus
There is no new customer bonus when it comes to Grosvenor and poker, but there are a number of existing customer pluses that are worth discussing here. There are daily tournaments to play in with some big cash prizes on offer. There is a big autumn tournament where 5 million can be won as well as monthly cash games and the chance to win money from the National Poker League to boot.
Frequently asked questions about Grosvenor
The casino sign-up offer of Grosvenor is bet £20 and get £30. That is split as up to £20 to match your deposit and then £10 on a specific game As with most offers when it comes to signing up with a casino, there are some wagering requirements which, in this case, require bettors to play through their winnings 5 X before they are able to withdraw it.
That makes things a little more difficult but most bookmakers have play through amounts on a casino offer. So, when it comes to how it compares with other bookmakers, it would be similar. It is not a superb offer but at the same time, it is also not the worst one out there and is worth looking at if you are not a sportsbook fan.
This is a question that only you as an individual can answer but we have a few thoughts to help guide you onto the right path. First and foremost, there are 60 days in which to use the boost so there is no need to rush into a decision. As it can be used on any sport and at any price, there are a lot of different options open to you when it comes to finding the right selection for your double-the-odds boost.
The most sensible thing is to find a sport that you know well and have bets upon, on a regular basis. Find a bet that you think is already a good price to make the most of it. That does not mean it has to be 100/1 but equally if you find one at 2/1 that you like then a winner will still provide a profit.
No, it is not possible to use one across all of the games at Grosvenor. The list of games where you cannot use it are as follows: American Roulette, Monopoly Live, Super Sic Bo, Caribbean Stud Poker, Deal or No Deal, Texas Hold'em Bonus Poker, Ultimate Texas Hold'em, Automatic Roulette, Silver Roulette, VIP Live Roulette, Classic Roulette, and Black Gold Blackjack. These are also off limits: All Baccarat & Craps game variations, Bruce Lee, Fairytale Legends: Hansel and Gretel, Dead or Alive II, Extra Chilli, Gong Xi Fa Cai, Gonzo's Quest, Fortunes Of Sparta, Guns N' Roses, Jungle Spirit: Call of the Wild, White Rabbit, Cash Eruption, Immortal Romance, Thunderstruck II, Vikings Go Berzerk, Lucky Leprechaun, Raging Rhino, Scarab, Temple of Treasures Megaways, Medusa Megaways, Spirit of the Valkyrie, Super Monopoly Money, Vikings Go To Hell, Football Studio and Dragon Tiger.
There have been ways to win free spins on Grosvenor Casino in the past, including their very popular Wheel Of Spins promotion that could see the bettor gain free spins on a daily basis. That is back for a limited time over the summer, the current end date on their website is slated as the 24th of September 2023 at the time of writing this review.
There is a wealth of other promotions across the site, as well so there are always options to win other prizes, as well as free spins, which is one of the biggest plus points that Grosvenor has over its competitors. Given that knowledge, it is hard to believe that there are not going to be plenty of opportunities for customers to receive free spins from Grosvenor in the future.
