Summary box

No, the interest rate is fixed and will not change for the term.

We guarantee to pay the interest rates shown provided a deposit is paid into the account within 14 calendar days of the account being opened. If the interest rates have increased by the time the first deposit is received, you’ll automatically receive the higher rate.

Deposit at account opening Balance at end of term Interest earned

ISA Transfers

When you open your account, you’ll be asked at the start of the application if an existing ISA is to be transferred. If it is, towards the end of the application you’ll be asked to provide the details of the ISA to be transferred.

Where your existing provider subscribes to the electronic Cash ISA transfer platform, your request will be submitted electronically.

If your existing provider doesn’t subscribe to the electronic platform, you’ll need to print and send us a completed ISA transfer form, which is provided to you at the end of your application.

Please make sure that any ISA Transfer Forms are returned within 14 calendar days from the date of application.

Fixed Rate Cash ISA FAQs

You can split your annual ISA allowance across the different ISA types - Cash ISA, Stocks and Shares ISA, Innovative Finance ISA and Lifetime ISA - or save the whole allowance in one type of ISA (apart from the Lifetime ISA, which has a limit of £4,000).

Aldermore offers Cash ISAs only. You can split your Cash ISA allowance between any of our Cash ISA products. This will be classed as one Cash ISA for the purposes of tax-free allowances and HMRC reporting. We're currently one of a limited number of providers that offer this

If you’ve got existing ISAs with other providers from previous tax years, these don’t count towards your £20,000 annual allowance so you can transfer these to us in full. By bringing all of your ISAs together in one place, you can manage your ISA portfolio with ease.

The current tax year allowance (ends 5 April 2024) is £20,000.

We’ll contact you a minimum of 21 calendar days before your account matures to explain your options, with an additional reminder issued around 14 calendar days prior to your account maturing. You’ll be able to view your maturity options and provide your maturity instructions by logging into your account in Internet Banking.

If we don't hear from you we will move your money into our 30 Day Notice Cash ISA.

If you want to transfer your Cash ISA to another provider, you will need to contact the provider that you would like to transfer your Cash ISA to and ask them to either send us the relevant ISA Transfer Request Form or send us their instructions electronically. You’ll need to give your new provider your Aldermore ISA account number as the roll/reference number. A sort code shouldn’t be required.

If you want to withdraw all or part of your Cash ISA, you will lose the tax-free status on that money. If you ask for this to be returned to your nominated account, the funds will be sent by Faster Payments on the maturity date (providing we receive your instructions online or in writing prior to the maturity date). In the event that the day of maturity is a non-business day, the funds will be sent on the next business day. You will receive interest until the day before the funds are returned. For example, if the day of maturity is a Saturday, you will receive interest until Sunday and funds will be returned on Monday (providing this isn’t a Bank Holiday).

You can transfer an ISA by following the usual transfer process. All of our Cash ISAs are flexible but if you transfer them to another provider, the provider that you transfer to may not offer flexibility in which case your ISA will no longer be flexible when it moves to them.

If you transfer an ISA from another provider into one of our Cash ISAs, it will automatically become flexible.
