If you have excluded yourself from bookmakers in the past due to concerns over your gambling then we would not recommend Matched Betting for you. We direct you to Bookmakers and Casinos and although matched betting is not gambling, these sites could still tempt you to gamble.
You would also likely struggle to matched bet too, unless you were able to reverse the exclusion by contacting the bookmakers.
If you were to give matched betting a go and feel yourself straying away and starting to gamble we would encourage you to seek support from professional organisations.
You can easily self-exclude from all betting sites using GAMSTOP - https://www.gamstop.co.uk
The GamCare website also provides ongoing professional support - https://www.gamcare.org.uk
