Transferring from an Existing Cash ISA

An ISA transfer is when you switch your ISA savings to a new provider. You might do this to get a better interest rate, or to take advantage of a different type of ISA altogether. You can transfer an existing ISA elsewhere into your NatWest Cash ISA at any time, bringing all your ISAs together in one place.

Full details on how to complete an ISA transfer can be found here.
