Interest is paid on a tiered basis which means you'll earn one rate on your entire account balance. Interest is calculated daily and paid into your account on the first business day of the month and at account closure.

This is only an illustration of what you could save and assumes that no further deposits or withdrawals are made, that there aren’t any changes to interest rates or tiers, and any interest earned stays in the account.

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 Savings Account Terms (PDF, 605 KB).

Eligibility

You must:

• Not have subscribed to another cash ISA with us or have subscribed to more than the overall subscription limit in total to a Cash ISA, a Stocks & Shares ISA, an innovative finance ISA and or 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. We will also need your email address and mobile number to open your account and send you important account opening documents.

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 a NatWest Help to Buy: ISA.

Making payments to NatWest Cash ISA and a NatWest Help to Buy ISA

You can make payments to a Help to Buy: ISA in the same tax year as a NatWest 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. Click here to find out more.

Yes. No notice is required. This account is a non payment account.

You can withdraw money:

• In branch or by transfer to any other account based in the UK (online, by telephone or on the mobile app).
• 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.

There are daily limits on the amount you can transfer from your account online, by telephone or on the mobile app. The current daily limits and how to withdraw more than them can be found here or by contacting Telephone Banking.

Definitions 

• Annual Equivalent Rate (AER) shows the interest rate if interest is paid and compounded once each year. AER helps you to compare the rates of interest on different accounts.
• Compound interest is interest that is earned on interest that’s already been paid.
• Gross means the interest rate you are paid on your savings with no compounding.
• p.a. per annum (per year).
• Tax-free.  We pay all savings interest without the deduction of tax.  You do not pay any UK tax on interest earned in ISAs. You may have to pay tax on interest earned in non-ISA accounts depending on your Personal Savings Allowance. The tax treatment may be subject to change in the future.
