Below is a full breakdown of how the Kwiff betting offer for the Grand National works, its key terms, and how to claim it.
What is the Kwiff Grand National welcome offer?
The Kwiff Grand National offer is available to new UK customers who register, deposit £10 and place a qualifying bet of at least £10 on any sports market at odds of evens (1/1) or greater.
Free bets are credited once the qualifying bet settles, typically within 48 hours.
The following bet types do not count as qualifying bets: wagers placed using free bets, bonus bets, vouchers, or other promotional stakes. Bets on virtual sports, each-way bets, multi-bets, cashed-out bets, surprise bets, and voided bets are also not eligible as qualifying wagers.
Free bets come as three different forms for those eligible:
- 1x £10 single bet.
- 2x £10 accumulators (minimum three selections).
- 1x £10 bet builder (minimum three selections).
Free bets carry a seven-day expiry and a minimum odds requirement of 1/1. There are no turnover requirements on winnings — the stake is not returned, but any winnings are added to your withdrawable balance.
Is there a promo code for the Kwiff Grand National offer?
No promo code is needed. The Grand National offer is open to any new customer who has not previously held a Kwiff account. Register, deposit £10 and place a qualifying bet to activate it.

First past the post: Get paid out if your horse crosses the line first but is later demoted, or is retroactively awarded the win following a steward’s enquiry.

Extra places: Kwiff are one of the best horse racing betting sites when it comes to extra place races at Aintree, covering the majority of races at the festival with enhanced each-way terms.
Responsible gambling
Please gamble responsibly if you are considering the Kwiff welcome offer or any other promotions. Betting should always be treated as a form of entertainment, not a means of generating income.
Set a budget, stick to it, and never chase losses — gambling can be highly addictive and it is important to stay in control.
All licensed gambling sites, whether online bookmakers, online casinos, or slot sites, provide a range of responsible gambling tools, including deposit limits, loss limits, and self-exclusion. We encourage all bettors to make use of these when needed.
If you feel your gambling has become a problem, the following UK organisations offer free counselling, support groups and practical advice:
