One of the main concerns people have before they start betting is the idea that signing up for an online bookmaker is going to impact on their credit.
Well it won't, so that's one less thing to worry about.
That's not the end of the discussion though, credit isn't the only thing you need to consider.
There is, however, the potential problem of people seeing your account and making a judgement on it. If, for instance, you were applying for a mortgage or other loan then having the names of internet betting exchanges, bookies and casinos on your bank statements may be frowned upon.
One friend of mine decided to apply for a mortgage recently and his broker advised her to stop gambling or at least move the activity to another account.
More recent mortage rule changes mean expenditure is more important than simple affordability tests. If someone is spending a lot of money on gambling, does Barclays or whoever else really want to lend to them?
If you are matched betting, and therefore not really gambling, it shouldn't really make a difference. Even if you're losing, provided it is affordable, then you could say it was a hobby, an entertainment expense no different to the cinema. But that's not how banks see it, they see danger in bookmaker deposits, even if the withdrawals are bigger.
The solution is pretty simple, get a Skrill account. A digital wallet lets you keep your betting separated from your day to day spending (and also the eyes of the bank manager or mortage broker). It's simple and free to set up (you only need an email address), and also the quickest way to get your money transferred between accounts.
