The new Mini Cash ISA fixed rate savings option and M&S fixed rate savings are guaranteed interest rates up to 5.70% AER/gross. These products are available both inside and outside an ISA wrapper.

Mini Cash ISA customers can choose between fixed and variable rates of interest, or split their annual allowance between the two, using one simple application form. Anyone aged 16 and over can put up to GBP3,000 per tax year into a Mini Cash ISA, with the advantage of all interest being tax free.

Following Bank of England base rate change, the M&S variable Cash ISA rate will change from 5.75% to 5.50% AER/tax-free, with effect from December 7, 2007. The variable rate is guaranteed to match the Bank of England base rate until June 30, 2008.
