Hi Jackie,
If you could use a second bank account that might be better for you long-term, especially if you’re looking for a mortgage.
Obviously Matched Betting will make you money, but the banks wont take the time to understand it. Its annoying but they’ll probably look at betting in a negative light. So if you could have a second bank account for matched betting and a normal bank account for daily bills that would work. I know its more effort to set up!
