The William Hill free bet is for £25.00 and is what’s known as a ‘Free Matched Bet,’ this is where you get a free bet up to the value of your qualifying (first) bet, whether that qualifying bet wins, loses or draws. These sorts of offers are ideal free bets to use for matched betting.
To qualify for the William Hill free bet you need to first open an account using a valid promo code, then place a qualifying (first) bet on an event at odds of 1.5 (1/2) or greater. The free bet is only available to residents of UK, Republic of Ireland, India, Canada and Netherlands, and is only valid for 7 days after you receive it.
I would be looking for a return of £13.75 (55%) from the £25.00 William Hill free bet, my article about how matched betting works explains in more detail how to achieve this.
Like with all free bets and betting offers in general, please make sure you have read the terms and conditions on the online bookmakers‘ websites and that you fully understand what you are doing before you part with any hard earned cash.
