The worst is the Government-run bank, National Savings, which takes two weeks to clear a cheque into its ordinary savings account. To add insult to injury, interest is payable only on the first day of the month after you have paid in the cheque. So you could wait more than four weeks for interest to kick in.ut both refrain from paying interest on savings accounts for a total of five days, up to two days longer than Abbey does on its current accounts. When you pay a cheque into a building society savings account it can take up to 12 days to clear.
