Ive just signed up for a new high interest online savings account at ICICI Bank. This great account has no minimum payments. As long as you pay in a Â£1 to open the account you are fine. The account is convenient allowing easy online transfer of funds into the account. At the same time it has a nice high interest rate of 5.65% AER.
You can read more and sign up for the account online here
I will shift some cash into this account and leave it here (until such a time when another savings account comes out that will beat this rate)
