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.

    Online set up was very straightforward. ISA transfer from another supplier was completed in 3 days. Kept fully informed throughout the process.

  • Very easy to deal with Mrgee

    The transition of an ISA from a-another bank ( offering a much lesser rate ! ) was found to be very easy with good communication from Aldermore. Aldermore chosen following search on internet

  • 1 year fixed rate cah ISA review CenturyC

    Because I had previous experience of transfering cash Isa to Aldermore for family member, I was confident procedure would be straightforward and speedy. This proved to be correct. This product has the best interest rate currently that I could find among trusted providers.

  • User friendly and great service Anita

    It's easy to compare rates but much harder to judge the service of a bank which is new to you. Aldermore offers those little touches which some others do not, for example a reply paid envelope to return documents or correspondence and a 7 days a week telephone line service.

  • Good experience. Eric15

    Simple changeover from existing ISA provider, no hassle and I was kept informed throughout. Many thanks.

  • overall service quite good wissy

    It took too long to reply to my letters and documents and contact numbers were not that obvious for chasing up. But would invest in A again.

  • Straight forward and competitive Bay1

    I understood from the website that I could open this account over the phone but this was not the case. However when I did ring the person I spoke to was friendly and helpful and the appropriate forms and information arrived quickly. My account details have not yet been confirmed but so far all seems to be going well with good communication and no complications. The main reason I chose Aldermore was for the interest rate which is competitive.

  • Opening an account was so easy Graham70

    I was extremely impressed with my first experience of opening an account with Aldermore. The forms were easy to complete and extremely quick to fill in. The response from Aldermore was rapid and within a few days of opening the account I received written confirmation with all the necessary passwords. First class Customer Service.

  • very straightforward Fiona57

    I went for a bank with the best rate first and chose Aldermore. It was then the most straightforward process for opening an account I have ever had. It was also very clear 'what to do next' and 'how to pay' the money in etc. Very happy with the service

Reviews for Fixed Rate Cash ISA 3 Year

  • 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.

  • 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.

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

  • 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.

  • Very easy to open the ISA account peewee

    Pleased with the ease of which I could open this ISA account being a new customer. Paperwork/e-mails received very quickly. Was able to go on line within days of opening to see my account.Would certainly recommend. Thank you
