We only accept Cash ISA transfers from providers registered through the industry’s electronic transfer scheme, which we use at Tandem. To be eligible, your current provider must be part of this scheme, and the account must have a valid UK sort code. Most ISA managers are included.

Open a Tandem Cash ISA

Want tax-free interest? Here’s how our Instant Access stacks up against our Fixed Rate options.

Before starting a transfer, you’ll need to have a Cash ISA opened with us. 
Choose from:

Instant Access Cash ISA – dip into your savings any time 

Fixed Rate Cash ISA – rate locked for a set term; early withdrawal may incur a penalty

Don’t worry, opening one is quick and easy in the app.

03

Start your transfer in the Tandem app

Want tax-free interest? Here’s how our Instant Access stacks up against our Fixed Rate options.

Once your Cash ISA is open, you can start the transfer. We’ll ask for a few details:

1. Your personal info
  • Name
  • Date of birth
  • Address
  • Contact number
2. Existing ISA details
  • Provider name
  • Account number
  • Sort code
  • Roll number (if you have one)
3. Your contributions this tax year 
  • The total you’ve paid into any ISAs this tax year (not including interest)
04

Choose how you want to transfer

Want tax-free interest? Here’s how our Instant Access stacks up against our Fixed Rate options.

You can move your Cash ISA in a few different ways, depending on how and when you’ve contributed:

1. Whole account balance

All of it, including interest from both this year and previous years.

2. Current tax year contributions only

You’ll need to transfer the full amount you’ve paid in this tax year (including interest).

3. Current year + part of previous years

Everything you’ve added this tax year, plus some of your older contributions.

4. Previous years’ contributions only

You can move your old ISA savings without affecting this year’s allowance.

5. Partial transfer from previous years

Just some of your past ISA savings. Keep the rest where they are.

Important: You must transfer the full amount of any current year contributions. We don’t offer partial transfers for the current tax year.

05

Tell us how to handle any exit fees

Want tax-free interest? Here’s how our Instant Access stacks up against our Fixed Rate options.

Your current provider may charge a fee for transferring out. In the app, you can choose to:

1. Wait until funds are available

We’ll wait until your ISA is fee-free to transfer, to avoid any penalties.

2. Transfer immediately

We’ll move your funds right away, even if your provider charges a fee.

Important: Tandem doesn’t cover any fees or penalties, so it’s a good idea to check with your current ISA provider first.

06

Sit back and we'll take care of the rest

Want tax-free interest? Here’s how our Instant Access stacks up against our Fixed Rate options.

Once you’ve submitted the transfer request in the Tandem app, we’ll handle everything from here.

Heads up:

  • Transfers usually complete within 15 working days 
  • If anything’s missing or delayed, we’ll let you know
Start a transfer in the app
Transfer Out

Want to transfer out of Tandem?

You can move your Tandem Cash ISA to another provider at any time. Just start the transfer with your new provider and they’ll handle the process. We’ll make sure your funds are transferred safely, usually within 15 working days.

Heads up! If you’re transferring a Fixed Rate Cash ISA still within its term, an early withdrawal fee will apply.
