Summary Box

Account name: Cash ISA

1. What is the interest rate?

2. Can Ulster Bank change the interest rate?

Yes, these rates are variable. If the rates are going down and your balance is £100 or more, we'll give you at least 14 days' notice. If the rates are going down and your balance is less than £100, we'll inform you before the change or shortly afterwards. If the rates are going up, we'll inform you before the change or shortly afterwards. For more information please see the Your Savings Account Terms (PDF, 342 KB)

3. What would the estimated balance be after 12 months based on a range of deposits?

These are only examples and do not take into account your individual circumstances. They assume that no further deposits or withdrawals are made; there is no change to interest rates and tiers; and any interest earned stays in the account.

4. How do I open and manage my account?

Your eligibility

Cash ISAs are open to existing Ulster Bank current account customers aged 16+. You must be resident in the UK for tax purposes.

You can apply for a Ulster Bank current account at the same time as your cash ISA application if you don't already have one.

You can only hold one cash ISA with Ulster Bank.

If you already have a cash ISA with us, keep paying into that account.

You must:

  • not have subscribed to another cash ISA (including a Help to Buy ISA with another provider) or have subscribed more than the overall subscription limit in total to a cash ISA, a stocks and shares ISA, an innovative finance ISA and a lifetime ISA in the same tax year;
  • hold the account solely in your name.

You can open and manage your account on our mobile app, online or by telephone.

To open in branch you must bring your own digital device such as a mobile or tablet and our staff can assist you opening the account yourself. You'll of course be able to phone us too if you need help managing your account. You can also pay money into your account at one of our cash deposit machine

Balance and ISA allowance

There is no minimum deposit required to open the account, no minimum deposit needs to be made on a regular basis, and there is no maximum balance limit.

However, there is a limit on the amount you can pay into your account each tax year (6 April to 5 April). This annual limit, also known as your ISA allowance, is set by the Government and may change from time to time. For the current tax year it is £20,000.

If you pay in more than the limit any excess money will be returned to you.

If you make a payment for a tax year into your Cash ISA, you can’t make any payments for that tax year into any other cash ISA except for an Ulster Bank Help to Buy ISA.

Making payments to both an Ulster Bank Cash ISA and an Ulster Bank Help to Buy ISA

You can make payments to a Help to Buy ISA in the same tax year as an Ulster Bank Cash ISA provided that:

  • the Help to Buy ISA is held with us; and
  • you don’t pay in more than the  ISA allowance between the Cash ISA and the Help to Buy ISA.

You can transfer all or part of any ISA held with another provider to us.

5. Can I withdraw money?

Yes. No notice is required.

You can withdraw money:

  • in branch;
  • by transfer to any other account based in the UK (online, by telephone or on the mobile app)
  • using your CashCard

If you make a withdrawal, you will not be able to deposit more money into your account if it means you will exceed the annual limit.

You can transfer your ISA (or part of it) to another ISA manager.

Please note there are daily limits on the amount that can be transferred from your account online, through telephone or mobile banking.

Information on the current daily limits is available on our website or by contacting Anytime Telephone Banking.

6. Additional Information


AER: Stands for the Annual Equivalent Rate. It shows you what the rate would be if interest was paid and compounded each year.

Gross: The interest rate you are paid without the deduction of UK income tax.

p.a.: per annum (per year)

Bring all your ISAs together to one place

You can transfer funds from an ISA with another provider by completing our Cash ISA transfer form, or if you bank online you can use the paperless transfer request, remember it can take up to 7 days to complete your ISA transfer request.

How do I get additional support with my banking?

Banking My Way is a free service that allows you to record information about the support or adjustments you need to make banking easier. You can also let us know any additional support you may need to ensure all of our colleagues are aware of this. The information will be shared on our internal systems and therefore you will not need to repeat these requirements every time you interact with us.

Once your account is open, you can record this through Anytime Banking or with our colleagues in branches or over the phone.
