Interest is calculated daily and paid annually to your ISA on the first business day in April and on the Maturity Payment Date.

No, the interest rate is fixed. This means that the rate will not change between the date you open your account and the Maturity Date.

4. How do I open and manage my account?

Eligibility

You must:

Be aged 18 years or over and resident in the UK for tax purposes.
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 need your email address and mobile number to open your account.

You can make payments in branch and by telephone. We will send you a certificate of deposit within 14 days of the term start date either to your secure inbox or by post.

Balance and ISA allowance

Your deposit must reach your account by 11 May 2026. You must deposit at least £1,000 (the “Minimum deposit”) by this date. There is no maximum deposit and no maximum balance; however, there is a limit on the amount you can pay into your account each tax year (“ISA allowance”). This limit is set by the Government and may change from time to time. The ISA allowance is £20,000 for the current tax year.

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

If you make a payment into your Fixed Rate ISA you will not be able to make any further 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 Help to Buy: ISA in the same tax year as a NatWest Fixed Rate 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 Fixed Rate ISA and the Help to Buy: ISA.

Transferring in balances from other ISAs

You can transfer all or part of any ISA held with another provider to us by completing an ISA Transfer Request form.

5. Can I withdraw money?

You can withdraw money from your account (in branch or by telephone) until 11 May 2026 at 3.30pm. Partial withdrawals are not permitted after this time.

If you want to make a withdrawal after this time and before the Maturity Date, you must close your account by giving written notice to your branch. An Early Closure Charge will apply, except in the event of your death.

The Early Closure Charge will be the lower of the amount of interest earned on your account or 90 days’ interest.

The Early Closure Charge will be deducted from the balance of your Fixed Rate ISA.

The total amount you receive (including interest earned on your balance) will be no less than your deposit at the Start Date. For example, if you have earned 50 days’ interest you will only be charged an Early Closure Charge equivalent to 50 days’ interest. If you have earned 100 days’ interest you will only be charged an Early Closure Charge equivalent to 90 days’ interest.

For more information on closing, please see the Fixed Rate ISA Terms (Term 8).

Transferring your ISA

You can transfer your ISA to another ISA manager. If the transfer is before the Maturity Date, we’ll convert your ISA to a Cash ISA and an Early Closure Charge will apply. If you want to transfer your ISA without incurring an Early Closure Charge the transfer must be dated at least the day after the Maturity Date, when your money is accessible.

Maturity of your ISA

On the Maturity Date (or if the Maturity Date is not a business day the next business day), we’ll convert your account to a Cash ISA. You’ll be able to access your mon

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.
