The trouble with deposit accounts is your savings are taxed (unless you are a non-taxpayer), and you are often penalised for withdrawing cash at short notice.
The big advantages of a Virgin Cash ISA are...
That means 20% higher returns - 40% if you are a higher rate taxpayer.
Tax treatment depends on individual circumstances and may be subject to change.
The cash in your Virgin ISA goes into a personal deposit account with The Royal Bank of Scotland plc.
