If you are looking to bet on sports using spread betting you'll need to open a spread betting account. Spread Betting accounts can be opened - subject to credit checks - at Sporting Index which is regulated by the FSA in the UK.  When you open a sports spread betting account with Sporting Index you might be eligible for a bonus promotional offer, however, please check the site for this. 

When you place a sports spread bet you might find that that the amount you lose is greater than your stake so you should always bet with caution. Make sure that you understand how sports spread betting works before betting with firms like SportingIndex.
