Grosvenor Welcome Offer – Double the Odds

New players at Grosvenor will be able to benefit from the Double the Odds welcome offer, available for all sports, all bets, and all odds. Double the Odds applies only to fractional odds. Once players receive the Odds Boost token, they will have 60 days to use it.

The betting bonus cannot be used in conjunction with any other offer on the gambling site. Note that this bookmaker doesn’t accept PayPal to qualify for the welcome offer, but we have reviewed a full list of PayPal betting sites that do if you prefer using this payment method.

How to Claim the Grosvenor Welcome Offer

Other Important Grosvenor Sign-Up Offers Terms and Conditions

Grosvenor also runs regular offers for registered customers at the casino. Keep in mind that these promotions come with specific terms and conditions. This is why we’ve broken down the key details you need to know below.

Casino

New casino players at Grosvenor can get £40 when they deposit £20. Once newly registered customers sign up and deposit a minimum of £20, they will be eligible for a £20 bonus, bringing their total cash balance to £40 to play with. The bonus will be available on selected slots and live casino games. Note that deposits made with PayPal or PaysafeCard are not eligible for the offer. The bonus and the deposit amount will be subject to a 10x wagering requirement. Not all games contribute equally to the casino bonus wagering terms. Slots contribute 100% while live casino games contribute only 10%. Jackpots and progressive games contribute 50%. Once the bonus is received, players have 30 days to complete the rollover requirements. The maximum amount that can be converted from bonus to cash is £2,000.

Grosvenor Bonuses for Existing Customers

Grosvenor runs a good variety of ongoing offers, providing players with enough opportunities to boost their bankrolls. We have outlined the ones we think have the best value.

Best Odds Guaranteed

This is part of the exclusive offers at the Grosvenor sports betting section and is available for horse racing events. The offer will be eligible for existing customers after 9 a.m. on the day of the race. When the player bets on a horse and the starting price is higher, Grosvenor will pay out at the higher odds. The max bonus is £25K. The offer applies only to singles and multipliers.

Daily Free Spins

To take part in this promotion, registered customers have to log in and stake at least £10 on any slot to get 5 free spins daily. The bonus spins will be credited instantly to the player’s account. Note that once received, the spins will be valid on the following games: Eye of Horus, Jackpot King, The Goonies Quest for Treasure 2, and Wish Upon a Cashpot.

Grosvenor Responsible Gambling Tools

Grosvenor is a legit gambling site licensed by the UK Gambling Commission. Players’ safety is the operator’s top priority, and, therefore, it offers tools for self-exclusion to help players properly manage their gaming behaviour. Here are the options customers can use.

Other Bookmaker Bonus Codes and Promotions

Without a doubt, Grosvenor is a top gambling site where players can find attractive welcome offers and a wide range of engaging ongoing promotions. However, other online betting sites also offer competitive bonus offers, which we have outlined below.
