I am still a fan of cash ISAs. The rates are creeping up in the run up to the end of the financial year.
Some other options,like some current accounts which pay good rates, may seem tempting but there is usually a limit to how much can be paid in to them.
The £1,000 interest we are allowed to earn before tax is payable is good, but if interest rates continue to rise, albeit slowly, then it would be very easy to reach that limit with only a reasonable amount of life savings.
And of course (perish the thought) were Labour to move into no. 10, any generous tax allowances could vanish in the blink of an eye.
