I break betting odds news as it happens, so you’re never left behind when the market moves or a top offer lands.
- Grosvenor Sport is offering new customers a 100% Odds Boost token on their first bet up to £10, effectively doubling the odds
- Winnings from the doubled-odds bet are paid in cash, not free bets
- No minimum odds requirement on the qualifying bet, and the token is valid for 60 days
Grosvenor Sport is running one of the more distinctively structured new customer welcomes on the UK market, a Double the Odds promotion that gives new punters a 100% odds boost on their first bet up to £10, with winnings paid in cash rather than as a free bet.
There's no minimum odds requirement, no wagering requirement on winnings, and a generous 60-day window to use the token, making it a genuinely different structure to the standard "Bet £X Get £Y" template most rival betting sites run.
Alongside the welcome, Grosvenor Sport also offers Best Odds Guaranteed on every UK and Irish race.
As the online arm of one of the UK's most established casino brands, Grosvenor sits under the same Rank Group umbrella as Mecca Bingo
New customers. Max £10 (Exc PayPal). 100% Odds Boost token. T&Cs apply.

How to Claim the Grosvenor Sport Welcome Offer
1. Register with Grosvenor Sport
Sign up for a new Grosvenor Sport account and complete verification.
2. Deposit
Make a first deposit via an eligible payment method — PayPal is not eligible for this welcome offer, so use debit card, Skrill, Neteller, Paysafecard or bank transfer.
3. Place Your Qualifying Bet
Bet up to £10 on any sport at any odds. There is no minimum odds requirement on the qualifying bet, meaning heavy favourites are eligible.
4. Get Double the Odds — Winnings Paid in Cash
If your bet wins, the odds are doubled and the winnings are paid in cash — no free bet mechanic, no wagering requirements, no restrictions on how you use the winnings.
Understanding the Double the Odds Structure
The Grosvenor Sport welcome is structurally different from most UK welcomes, and it's worth walking through how the value scales.
Bet £10 at 3/1 (4.0) → normal return £40 (£10 stake + £30 profit) → Doubled odds = 6/1 (7.0), effective return £70 (£10 stake + £60 profit). Extra £30 paid in cash.

Best Odds Guaranteed on UK and Irish Racing
Alongside the welcome offer, Grosvenor Sport runs Best Odds Guaranteed on all UK and Irish horse racing, active from 9am on the day of every race.
How BOG works: if you back a horse before the race and it goes off at a bigger starting price, Grosvenor pays you out at the higher odds.
If the horse's SP shortens after you've backed it, you keep the bigger price you took.
