Offshor075,
Depends where you are currently based for residence and tax purposes. If still residing in the UK it looks like savings rates are going to stay low for the next year or two (worse luck) so you could compare 2 Year Fixed Rate Bonds with UK Banks or Building Societies.
If however you are Non-resident then you choices could be more limited regarding opening accounts with other UK banks, in fact it would be nigh on impossible without proof of a UK address. If going through an advisor for offshore products be a little careful of the Deposit Guarantee Scheme operating in the jurisdiction where your money would be placed.
When I jacked in work and went Non-Res in 2008, I only asked one IFA about what types of tax-friendly investments were available for myself and he tried to sell me an offshore bond invested through an insurance company with KSF on Isle of Man, their depositors have not seen any money back yet.
If you are still UK Tax Resident, just click through the money link at the top of this webpage and have a look at the fixed rate bonds and ISA's available bearing in mind that the limit for Cash ISA's is something like £5,100 per person per year since the changes came into effect this month.
