just ive seen these 0%apr things for 14 months and l wondered if l could move my over draft onto that.

Dont think so

If they issue credit card cheques - and they are eligible for the 0% deal - just write one out to yourself and pay it into your overdrawn bank account.

if u dont have cheques, do a cash withdrawal using credit card , lodge the money into the bank account

What is the point. You still have to pay interest on your overdraft.

It will vary from card to card, so read all the terms first. This site has some info, though it is 2 years old, it still covers some basics you may want to read.

''Unfortunately, most credit card companies have stopped customers using their cards to transfer money into current accounts. Most now regard the transaction as a cash advance, which incurs a 2% fee and accrues interest from day one.''

Generally, no.

Sorry to say this but-you are merely robbing Peter to pay Paul.
In english you ARN`T solving your problem.
Two factors in your question tell me alot-Creditcard and Overdraft,
you are obviously living beyond your income,like l used to.
SPEAK to your BANK about your situation,they dont bite,especially now when things are tight and banks dont want to lose customers.
Best wishes and good luck.
