How do I open and manage my account?

Your eligibility

You must be aged 16 years or over and resident in the UK for tax purposes.

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

 

If you already have a current account with us you can open your account on our mobile app, online or in branch.

If you don't have a current account with us you can open your account online or on our mobile app (you need to register for online banking before you can get our mobile app). 

We will need your email address and mobile number to open your account. 

You can manage your account on our mobile app, online, in branch or by telephone.

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 tax year 2019/2020 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.

Paying into more than one ISA

Making payments to both a 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.

Can I withdraw money?

This account is a non-payment account

Yes. No notice is required.

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 of money you can withdraw from your phone, online or on the mobile app. Find out more about the daily limit or speak to us on the phone about them.
