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

  • Excellent company for customer service Aeronaut

    I cannot take out additional investment with Aldermore simply because I have we nearly reached the maximum safe deposit of £85000 decided by the Government to protect investors if a bank goes bust.

  • best available rate at the time bobbys

    best rate at the time/ easy to set up, have used aldermore before and would use them again


    19 Oct 2014

  • an addition to my existing account spiderbowels

    Only average because when I originally enquired about a cash ISA I was told I would be given 1.6%, whereas once the account was opened this reverted to 1.5%. The lost sum is only £15.00, but I think this is poor service, particularly as I was assured that the interest rate would be 1.6%.


    17 Oct 2014

  • Very easy to manage accounts KEEPAU

    Dear Aldermore,Thankyou for your enquiry.I am happy to report that Myself and Isa(as I call her) are deliriously happy together.Who knew that a relationship with such a passive partner could be so fulfilling!On the physical side we are taking things a step at a time.Should total consummation elude us then we could perhaps consider adopting a few junior isas, but this assumes that the authorities are prepared to countenance a formal union between a human being and a financial product . More to follow as our mutual passion develops and thanks so much again for bringing us together.

  • suitable product Maxine

    The forms to complete to transfer funds from a closed ISA to a new ISA were not easy to follow and I had to ring up to ask. However the assistant could only offer me the same forms. They were not explicit for the transfer from an Aldermore account to a new Aldermore account. I did not find them fit for purpose.


    12 Oct 2014

  • Reasonable interest rate at the time. Daisey

    Reasonable product in the present clime as interest rates are low.


    09 Oct 2014

  • Fine in all respects except it took too long to complete behrcu08

    I first sent you all the forms on 19th August for an ISAtransfer in to you for an ISA which matured on 1st Sept. It was not until 1st Oct that you opened my new ISA a/c. I rang you twice to check progress and was told you were very busy. What concerns me is that I have lost a whole month where interest could have been accruing. I think you should have backdated the opening date of my new iSA.

Reviews for Fixed Rate Cash ISA 2 Year

  • Best rate icer on the market Ticker

    I was very sceptical at first changing my icer provider I needn't have had any worries as the service I received was excellent no long queues when phoning like many other competitors. The transfer was done very speedily and efficiently,


    21 Oct 2014

  • Good rate offered Derek2491

    Looking to move two ISA`s from another provider which matured on consecutive days, I made an initial email enquiry to Aldermore. Subsequent phone calls and the paperwork were dealt with quickly and efficiently and the transaction completed successfully.


    19 Oct 2014

  • little disappointed Ocky

    It took a while to initially create ISA as trouble with logging on, in the meantime the 2 year ISA rate had dropped from 2% to 1,85% NOT very good for customer relations.


    16 Oct 2014

  • Time taken to open account was unacceotable John1942

    I sent all the information needed for you to open the account on 26 August and advised that funds to be transferred would be available after 10 Sept. . It took you until 1 October to open the account. This was too long and cost me lost interest. A telephone call enquiring why there is a delay was answered very curtly, and still nothing happened. Not impressed.

  • Straightforward and very helpful staff BarbaraAnn25

    I have had both cash isas and fixed rate bonds over the years and always been very happy with the interest rates and especially the service I have received.

    Some staff are more helpful then others.But all are very friendly

    My account was set up without any delay or fuss and with friendly guidance from the staff.

Reviews for Fixed Rate Cash ISA 3 Year

  • Simple and straightforward process to open account!

    I was looking for a longer term cash ISA and Aldermore's offering seemed attractive. Opening the account was an eminently easy process and communications have been prompt and clear.


    06 Oct 2014

  • The question was "am I happy with" the 3 Year Cash Isa Optimist

    I'm reasonably happy but it's been basically having to make a choice of a pretty poor bunch of options. If Aldermore really wanted to make me happy then a better interest rate would go a long way to making me smile and start whistling a merry tune.


    06 Oct 2014

  • A very smooth transition Poundwatcher

    I chose Aldermore as they were offering the best interest rates. With great trepidation I gave instructions to transfer in an existing ISA. I was surprised how easy it was to do. It was completed within a few days and I was kept informed of progress as it happened. I truly could not have envisaged such good service. Hopefully they will stay ahead in the interest rate game and we can do more business.


    24 Sep 2014

  • Just what I was looking for!

    I found the 3 Year Fixed Rate Isa very easy to set up online and the staff were friendly and helpful on the queries I raised.


    24 Sep 2014

  • Provided what I wanted. Cat7

    Opening and depositing money into my new account could not have been easier and all completed within seven days.


    23 Sep 2014

  • speedy service

    Great web site with an easy to follow application form. everything worked first click and it only took 10 mins to make my application. Would deal with this company again.

  • What I was looking for Timmie

    Given poor savings rates at the moment, I did an internet search on ISAs and Aldermore came near the top. A telephone enquire was dealt with quickly and helpfully about transferring from another provider, referring me to their on-line application service. Surprisingly, this turned out to be as simple and efficient as predicted. Confirmation of my account being opened came quickly both by email and post. So far, so good.
