Savings and cash ISA applications

Everything you need to know about applying for our savings and cash ISA products.

What you’ll need to apply online

To start your application, you'll need:

• a UK mobile number – we’ll send one time passcodes (OTPs) and application updates to it
• an email address – you can choose to get application updates sent to it too (you’ll just need to verify it)
• your home addresses over the last 3 years
• if applying for a cash ISA, your National Insurance (NI) number

You may also need to:

• provide a document as proof of identity (UK passport, UK-issued photocard driving licence or residence permit), which we use to help protect your identity – we'll ask you for this through Onfido, our secure identity verification partner (if you do not have one of these documents, you can book an appointment to speak with someone in branch, on a video call or over the phone.)
• be using a device with a camera so you can take a selfie for an identity check – your image may be checked by our team, so make sure it’s suitable for review

To help protect you from fraud, we may ask you to provide more documents later. Read more about identification requirements.

About the application portal

The application portal is a secure place to see the progress of your applications.

If we need any more documents from you before we can confirm the outcome of your application, we'll also ask for these via the portal.

Applications for some account types will not appear in the portal.

Understanding application declines

We know it can be disappointing when an application is declined. There are a number of reasons this might happen.

Savings terms explained

AER stands for Annual Equivalent Rate and shows what the interest rate would be if interest were paid and added to your account each year.

Business day is usually Monday to Friday excluding bank holidays.

Calculated daily means the interest earned is based on the amount of money in your account at the end of each business day.

Calendar month means from midnight on the first day of a month to 11.59:59pm on the last day of the month.

Fixed interest means the rate stays the same until the account matures.

Gross is the rate of interest payable before any tax is taken off.

Tax-free means you will not pay any tax on your interest.

Tax year runs from 6 April to 5 April.

Variable interest means that it could go up or down.

Please note: any reference to tax is based on our understanding of current tax regulations which may change in the future and depend on the customer's individual financial circumstances.

The Co-operative Bank reserves the right to decline or accept any application and/or deposit.
