Can Santander change the interest rate?

No, the interest rate is fixed during the term.

At the end of term

We'll calculate and pay the interest for you on the date of maturity and it will be available to you from the following day.

You can choose what you’d like to do with your ISA up to 28 days before it matures. We’ll contact you around 14 days before maturity to tell you your options. If we don’t hear from you we’ll transfer your account to an ISA Saver (1.46 MB), paying 0.10% AER/tax-free (variable) for balances of £1+. 

How do I open and manage my account?

To open the account you must be:

  • a UK resident, account can only be held in single name; and
  • aged 16 or over.



  • Online and Mobile.
  • Visit any Santander branch.


ISA transfers

You can transfer in existing ISAs held with external ISA providers, applications must be received within 14 days of account opening and the funds in the ISA which you are transferring from must be available to be transferred within 30 days of account opening.

Santander cash ISA transfers in are allowed, applications must be received by 30 September 2022.

You can transfer the full balance of your ISA to another provider at any time, a charge equivalent to 120 days' interest will be applied. You will need to contact your new ISA provider to arrange the transfer.



A subscription is any deposit (or payment) made by you into an ISA.

There’s a minimum opening balance of £500, the maximum balance at any time is £2 million. You can open the account with a zero balance if you are transferring in existing ISAs with a balance of at least £500.

The ISA allowance for the 2022/23 tax year is £20,000 and deposits can be made up to and including 30 September 2022. No further deposits will be allowed.

These fixed rate ISAs are cash ISAs. Please be aware that if your deposits for any given tax year are less than the full ISA allowance for that tax year, you won’t be able to pay into another cash ISA in the same tax year to use the remaining allowance.

You can subscribe your ISA allowance into a cash ISA, a stocks and shares ISA, an innovative finance ISA and a lifetime ISA or a combination of the four. Santander do not offer innovative finance ISAs or lifetime ISAs.

For example, if you subscribe to one of these fixed rates ISAs you won’t also be able to subscribe to one of our other cash ISAs this tax year.

A tax year runs from 6th April in one year to 5th April the next.

This product doesn’t accept additional permitted subscriptions


Manage the account

  • Branch and telephone. View only in Online and Mobile Banking.
  • A certificate or email confirmation will be issued after account opening.
  • Statements are issued annually in March.

Can I withdraw money?

Partial withdrawals aren’t allowed. You can withdraw money by closing the account; a charge equivalent to 120 days’ interest will be applied.

Any money that you withdraw yourself from your Santander ISA will lose its tax-free status and if repaid back into an ISA, will count towards your current tax year’s ISA limit.

We aren’t offering additional flexibility on ISAs but some providers are offering this feature. Those providers may allow you to replace funds that you have withdrawn with them without affecting the ISA limit.

Additional information

You can cancel the account within 14 days of opening and your money will be returned in full with interest.

The favourable tax treatment of ISAs may change in the future and is subject to individual circumstances.

Subject to availability and may be withdrawn without notice. Rates and information correct as at  2 August 2022.

Transferring ISAs from other providers

You can transfer ISAs you have with other providers at any time, but we must receive the transfer request within 14 days of when you open your Santander ISA. The money you’re transferring must reach your Santander ISA within 30 days of opening. 

Before you transfer your ISA to us you’ll need to consider these points:

  • We don't charge a transfer fee but other providers may. 
  • You can transfer some or all the money that you’ve paid into an ISA in previous tax years. If you want to transfer money that you’ve paid into an ISA in the current tax year, you’ll need to transfer all of it. 
  • If you transfer an ISA in full to us and have built up previous tax year flexible allowances with your current provider, you’ll lose that allowance when you move to Santander. 
  • If you want to use the flexible allowance you should re-deposit into your existing ISA before you transfer to us.
  • Transferring money out of a Help to Buy: ISA will impact the bonus you may receive.

If your Child Trust Fund (CTF) is due to mature or has matured

You can transfer all or part of your maturing CTF, your matured CTF or Protected ISA to one of our cash ISAs. If your CTF is maturing, the transfer will only occur at the point of maturity, on your 18th birthday. If you only want to transfer part of the money held in your account, you must give instructions to your existing provider on what you want to do with the remainder before the transfer can be completed. We must receive the transfer request within 14 days of when you open your Santander ISA. The money you're transferring must reach your Santander ISA within 30 days of opening.

The ISA manager for Santander cash ISAs is Santander UK plc. For Santander stocks and shares ISAs the ISA manager is Santander ISA Managers Limited. This means that transfers between Santander cash ISAs and Santander stocks and shares ISAs should be treated as transfers between ISA providers, not transfers of existing cash ISAs with Santander.
