Thank me later, best deal out, 5% AER fixed ISA for 5 years (through July 2014)!
Minimum investment £1, further details via the link.
Expiry unknown but limited issue.
Thanks to my brother Luke for flagging this up!
EDIT: Lot of debate on this but basically the gamble is will interest rates be on average over 5% in the next 5 yrs for ISAs?
Highly unlikely there will be an exaggerated climb of the BofE base rate over the next two years anyway and 1yr ISA's are currently only returning around 2% for the main part.
You are not legally obliged to keep your money in for 5 yrs if you see a better opportunity elsewhere, of course. Personally I think the security and the nice rate make it a worthwhile proposal for those with a small amount to tuck away. *jfojut*
