if this is an isolated occurance then probably not. If this is something that has happened with other people you have cedit or firect debits with then I'm sorry to say this may be the case. Banks etc. understand that we can't be totally organised all of the time.....
Today i found out my direct debit bounced from vodafone will this affect my credit score?
In a word, no. Your credit will have a record of missed payments but generally speaking the score itself will only be affected if you miss several in a row (suggesting financial instability). So long as this is a one off, or particularly, it doesn't happen next month, you will be fine.
