Betfair is a new and exciting place to bet, where you’ll find the odds are on average 20% better than of a traditional bookie. It’s a market place where you can bet against other punters, not against a bookie, so the odds are almost always better as there is no bookmakers adding in their profit margin. Betfair is now the World’s No.1 online betting site with 500,000 bets matched daily.
Betfair was founded in August 1999 by Andrew Black and Edward Wray and in 2003 won a Queen's Award for Enterprise in the Innovation category following a full assessment by the Department of Trade and Industry, betfair has since become the largest online betting company in the UK and also is the largest betting exchange in the world with a turnover in excess of £50m a week and over 1,000,000 clients.
On Betfair you have the opportunity to bet 'punter to punter' where you can back and lay a team, dog, horse etc to win or lose thus you eliminate the need for bookmakers. i.e when you 'back' a team, dog, horse etc, you are betting that it will win just like you do with a bookmaker. Whereas when you 'lay' it you are betting against it winning, if for example you think England won't win the World Cup you lay England, you offer odds to other backers who wish to back England.(Therefore you are effectively betting The Field Vs Eng) If England don't win, then you pick up the backers stake, if England win then you pay out in a way that traditional bookmakers would.
Betfair claims it's odds are up to 20% better than an online bookmakers odds and whilst this may be true in most cases you have to take into consideration that they have a policy of taking commission (5% MAX) off the winning side of the bet.
