I'm interested in Halifax's 6.20% fixed rate mini-cash ISA for 1-4 years. I've had an ISA with NS&I for a couple of years now and although I have nothing to complain about their offerings (their current offering is 5.80%), as I have my other savings account with the Halifax, I wouldn't mind using the same provider.
Now my question is: Halifax offer to move funds from an ISA at a rival bank over to a newly opened account at the Halifax. If I move my savings across before the end of the tax year, will NS&I charge me, even though Halifax say it should cost nothing? How much interest will I use from this year's tax year.
One other question would be: is 6.20% guaranteed a good rate for 1, 2 or even 4 years? As it's fixed and NS&I seem to follow a policy of staying 0.30% above the base rate, in the next coming year it would seem that 6.20% will be well above the base rate but how about in a couple of years?
