If you want to keep funds close at hand, you will probably be most interested in the Instant Access ISA, which will allow you to:
- Withdraw cash without giving notice
- Use your passbook to monitor the account
- Open your account with just £1
However, if you are purely looking for the highest interest rates, you may wish to look at the 60 Days' Notice ISA, although it is only available to existing customers. For a selection of the latest ISA deals, see our comparison tables.
