Interesting! Im just reading the Cash ISA page on MSE (
http://www.moneysavingexpert.com/savings/cash-isa-transfers)
So, if you go with a variable rate (i.e. the Santander one at 2.75) this is obviously not fixed, but if interest rates go up, will this go up along side?
Im being completely naive on my ISA in the past, and I think I need to be a lot more proactive on it. Currently my ISA is with KRBS (1.02%)
The Alliance and Leicester / Santandar one I mentioned will, yes. Other variable ISAs may or may not, it's at the discretion of the bank. The key is this one is fixed at the Bank of England base rate +3% so it goes up (and down) automatically.
Currently it's at 3.5% for a year but
it's fixed at 3.0% above the BOE rate so if that goes to say, 2% this ISA will automatically pay 5%.
It is a stonking deal, however it's almost certainly guaranteed to revert to some really pants next year in the hope a huge chunk of people wont notice there'll be better deals around then. Banks do this with "normal" saving accounts from time to time. You have a savings account paying, say 2%. They then bring out the new "issue 9" version of the same account that pays 2.1% but at the same time drop the interest on th old one to .1%
They usually let you know but huge amounts of people just assume the glossy announcement is junk mail and so don't realise leaving their money sitting there getting a pants rate for ages. Especially where interest is paid yearly so you might not even notice savings that used to nett you £100 now net you £1 (or whatever).
Just make sure you check the deal after a year and move the cash elsewhere if you need to.
