Nothing beats knowing your savings are protected – both from interest rate fluctuations and from the taxman. With our Fixed Rate ISA you get a great return thanks to our guaranteed interest rate and it’s tax-free too. From 1 July 2014, all ISAs have become New ISAs (NISAs) and your annual tax free allowance has increased to £15,000. You can save the whole allowance in cash or in stocks and shares, or a combination of the two. You can split your allowance between any of our Cash ISA products to make the most of the increase. This will be classed as one Cash ISA for the purposes of tax free allowances and HMRC reporting.

Reviews for Fixed Rate Cash ISA 2 Year

  • one of the best on the market keef

    Having opened an internet savings account some months ago and found the service better than other providers I sought out Aldermore for my ISA. The 2 cash ISA serves my needs with a reasonable interest rate


    21 Aug 2014


    The interest rate was the best I could find to suit my needs and, having a savings account already, it was simple to move funds to the ISA and transfer from another provider. Telephone enquiry was dealt with efficiently and it all worked promptly.

  • Pleasant and efficient service Jenny

    I always need to talk through investments and at times ask what might seem silly questions. the staff always treat me with respect and give me the confidence to make my investment. Few organisations take ISA transfers, so you get my vote every time!

  • Good rate, simple application process Andy666

    Not wishing to tie up my savings for too long, I decided on a three year ISA. The best rate I could find was with Aldermore and I was pleased with how easy it was to open an account online. To date I have been very pleased, easy process, good online access and a decent rate in a market where these are hard to find. Thank you Aldermore.

  • Easy and quick Kendall

    I always groan when it becomes apparent that I have to transfer an ISA to get a better rate. However, my transfer to the Aldermore 3 year ISA was completely trouble free and undertaken with the minimum of fuss. I would certainly consider using this company again.


    20 Aug 2014

  • ideal product for my particular circumstances. scrooge48

    originally had a 3yr ISA, but changed to a 5yr fixed rate bond,as interest is paid monthly - gross, which suited my needs perfectly, as being an old pensioner with an income below the tax threshold, this is an ideal way to maximise my income, without putting my capital at risk.
