POSSIBLY 
A bank account overdraft can help you to improve your credit history if 
You have one on your bank account - this shows lenders that your bank trusts you.
You do not need to use it – showing you manage your money well and don’t need it.
If you use the overdraft every month you’ll see a negative impact on your credit report 
Suggesting to lenders that your expenses every month are higher than your income.
If you cannot live outside of your overdraft, consider getting a manageable loan instead, this will look better on your credit file.
