Hi, I have a Tesco Instant Access cash ISA which has matured and the interest rate has dropped to 1.25%, so I have opened a new Instant Access cash ISA with Tesco with a rate of 4.2%, How do I transfer the balance from the existing ISA account to the new ISA account whilst maintaining the ISA status? is it just via an internal transfer between the 2 ISA accounts using online banking or do I need to ring the Tesco ISA team to make the transfer?
