Fixed Rate Cash ISAs

Ratings & Reviews

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 1 Year

  • Just what i wanted Flash1

    Best rate that i could find for a fixed period 1 year


    25 Jul 2014

  • Product suited my needs Tina

    I couldn't understand why I you wouldn't send a blank transfer form to my sisters address instead of my home address. Surely this isnt a breech of the Data Protection act. This caused me great difficulty in returning the form within your specified timescale. Another bank allowed me 28 days to do the transfer why is yours so short.

  • Good competitive interest rate pat66

    I transferred an ISA from another provider - the transfer was carried out very efficiently on both sides.

  • Super Slick, Super Fast BigAl2

    In my never ending search for decent interest rates I came across Aldermore, low interest rate but best of the bunch. I opened an account on line on a Wednesday and by Saturday all my account details had been received in the post, by Tuesday my new deposit had cleared and by Wednesday of the following week my transfer in had been completed. I have been moving money every year since the big melt down and this is by far the slickest operation I have encountered.

  • suited my needs perfectly motherhen

Reviews for Fixed Rate Cash ISA 2 Year

  • Uncomplicated Service Scalemaker

    I was surprised at just how easy Aldermore made this transition from one provider to another. Normally there appears to be some apparently unnecessary complication but with this service provider all the checks etc., were made without any effort on my part.It was a pleasant surprise and they offered a decent rate of interest,unlike others.

  • Simple process Red6

    In my experience Aldermore savings accounts interest rates are invariably comptitive.

  • First class service twtlol13

    I decided to take out an ISA with Aldermore because it is a small , independent bank, not affiliated to the "big names". I set up my account online easy process. I have needed to ring the bank a couple of times with some queries and the agent on the other end of the phone was always helpful, courteous and efficient. And I was not kept waiting in a long queue ! How refreshing...... I was transferring funds from various other establishments and was sent regular emails so that I was fully informed of the progress of the transfer throughout. I am very pleased with the service provided by Aldermore. The bank's promise of "simple, straight- talking" savings was fully realised.

  • exactly what i was looking for welsh

    I found the assistants courteous, informative and easy to understand. The website also easy to follow.


    23 Jul 2014

  • Product adequate - service poor Pompey1

    I sometimes wonder if the people at the head of Aldermore ever read the claptrap put out by their copywriters. "Simple"? "Straightforward??". Yours is one of the most complicated procedures I've dealt with over many years. Having done the paperwork, I had to enquire the method of investing the money. A week later it was deducted from my bank account. Why a week later? are you so popular? or inefficient? or short staffed?

  • Good product simple to implement Unney21

    This was just the product I needed, simple to open and although not a fantastic interest rate, as good as was available.

  • It was what I wanted Trine

    There was a brief hiccup with respect to confirmation of my fast money transfer. It took a couple of days to sort this out. It was disconcerting at first and worrying, as the money was actually transferred to Aldermore within 2 hours of my opening the account. Apparently there was a software problem with the receiving of funds. I would not like to go through that again and hopefully I will not. Otherwise I am perfectly happy to invest my cash with the bank.


    23 Jul 2014

  • competitive rate of interest, quick and easy to set up on line Jay44

    Competitive rate of interest and quick and easy to set up the account on the internet - user friendly self-serve. One ISA already transferred to my 3 yr ISA from a former provider, just waiting on the second to be transferred

  • 3 YEAR FIXED CASH ISA TrendyWendy

    I was hard-pressed to re-invest my Cash ISA as the prices on offer are, to say the less, not brilliant. My provider quoted me an unacceptable interest rate even though I have had savings with them for five plus years. Aldermore seemed to offer the best rate, even though it is still very low. However as I had to put the money somewhere Aldermore seemed the best of a bad bunch. I liked the fact that Aldermore is a relatively new bank as I try to avoid the big banks who do not seem to be loyal to their existing customers. The switch over was painless and quick.
