Yes - savings accounts will pay on 31st Dec (ours do), others (like our Flex Account) pay monthly, ISAs (for all banks I believe) pay out at the end of the tax year.
At 17, is there one with a decent interest rate (compared to others) with possibly a debit card that i can use online? I can't use the cashbuilder account to buy online can I even though it has a card ?!
molly, ask Nationwide if they will open a Flex account for you. It's a current account with a debit card, and you can move money into it from your other accounts when you want to spend it.
