orthopod:
what is meant by Access By Post, following maturity.
does that mean that you can not access funds before maturity.
Yes - very good question. It might be that you can withdraw but are unable to transfer - rate tarts like me would want to do this, of course. I would not want to wait until maturity if a significantly better rate comes along.
EDIT: I think CentaurAndrew is mistaken. Just checked the terms and conditions, and it seems that you are expected to keep the account for the full 5 years. You can withdraw funds, but there is no mention of transferring to another ISA provider (as I would do if the rates elsewhere are better) - withdrawing funds means you cannot reinvest as a tax free ISA. So if you invest funds that you want to keep for a long term investment with a good rate, I would suggest this is not the best account as interest rates are expected to rise in line with an expected rise in inflation. The rate is excellent right now - but look back just one year to see how the rates have changed dramatically. I would guess similar dramatic increases in rates are on the cards within 2 years - a 5 year lock in is no good to me. So, although I voted hot - I believe it should have been cold for me.
