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

  • I needed something simple Christine59

    I wanted to open a cash ISA but had no time to research the market or complete a lot of forms. As I already have an ISA with Aldermore and the rate offered was reasonable I chose a one year fixed rate option. All my personal details were on file and I only had to tick a few boxes and authorise a transfer and the transaction was complete. Very satisfied with the simplicity so will probably do the same next year.

  • Competitive Interest Rate ForestGirl

    The account I chose compared well with others and was one of the higher interest rates. Opening the account on-line was easy and the transfer from an existing ISA with another bank went smoothly and on time.

  • Brilliant service, great experience Tiggerific

    I wanted to invest an ISA that was about to mature and wanted a safe haven that would bring me a half decent return. My husband had used Aldermore in the past and currently holds investment with them, so I thought I would give them a go. I'm a 'speak to' person, rather than a 'read it on the internet' person and so I rang to chat with a representative. I cannot praise the young lady I spoke with highly enough. She was polite, helpful, cooperative and enthusiastic about the product. She answered all of my questions and provided me with additional information, covering some issues I hadn't thought to ask about. Overall my impression at this very early stage was one of a professional organisation with a genuine interest in me. I was promised information through the post but decided to 'have a go' at an on line application as the person I spoke with encouraged me to do so, telling me it was very straightforward, but that I would always have the paper applications to fall back upon should I baulk at on line applications. I need not have worried, the application was SO simple and easy to complete and hey presto, within minutes I had my ISA opened and transfer arranged. The paper based forms arrived very quickly but of course I don't need them. Communications from Aldermore have been excellent, easy to understand and very reassuring. I am delighted with this organisation, so much so, I am about to transfer more funds to their ISA programme.

  • Competetive rates and excellent service Kelly55

    I recently opened a 2 year fixed rate ISA with Alderman. The interest rate was the best available and it was easy and straightforward to open the on-line account. I'm delighted with the excellent customer service, when I have telephoned Alderman I haven't had to wait more than a minute for my call to be answered and each time the agent was friendly, knowledgeable and efficient. I'm very pleased to have discovered Alderman.

  • quick and efficient charli

    I chose this Isa because the interest rate was competive. The whole procedure was simple and only took 1 week from opening for the money to be transferred from another provider into this new account. I particularly liked that i was kept informed of the progress from start to finish.

  • Gave me an easy transition of funds Mojo

    Having read the information on setting up and transferring funds it exactly replicated them on line. As a novice on the internet it was exactly what I was looking for. Thought the time scale was right in ensuring all security angles were covered - about 2-3 weeks in total. Thank you.

  • Competitive rates, good service Saver25

    I tried to open an account with Aldermore online but had a problem with the password, so I telephoned them and it was sorted out quickly and efficiently. I received confirmation of both of my accounts by post quickly, and I am very happy with the customer service. I would have given an overall rating 5 except for the online problem

    Happy with account opening process. Was slightly disappointed that I cannot add to the account on a monthly basis through to end of ISA year on April 4.

  • Great Experience Kaddy64

    Opening a 3 Year Fixed ISA account was very easy, and when I rang customer services to clarify a few points, I didnt have to wait an eternity and was given clear and concise answers. It really is a shame they dont have the full range of financial services.

  • Suited my needs perfectly Peter47

    I was attracted to the 3-year fixed rate NISA by the interest rate which pays a full half a per.cent more than my current provider.The transfers into my new Aldermore account from both my current account and my existing NISA were done swiftly and efficiently with no bother at all.

  • OK, but fund transfer slow and restricted Susan10001

    Opening the account was OK but transferring funds is very slow due to the need for a linked ESave account and a single deposit sum. It would be better to allow internet fund transfer but this was not possible due to a limit on the transfer amount from my bank. I would have thought that multiple payments into the Esave account would be OK, with a single transfer to the base rate linked account when it is opened. At this point I am still waiting for my accoun to be openned and for a welcome pack!
