Frequently asked questions

  • If it's a Cash ISA you want to transfer from another provider, simply complete and submit the Cash ISA transfer form. Alternatively, you can visit your local Santander branch. Some of our ISAs may not allow transfers in so please check the terms and conditions.


    Once we've received the completed form from you, we'll need to contact your existing provider, so please allow up to 15 days for a Cash ISA transfer to take place, starting from when we have received the transfer form.

  • All our ISAs allow access to your money but there may be restrictions or charges that vary depending on which ISA it is that you hold.
    Be aware that if you take money out, and you wish to put it back later, this will count against your annual ISA allowance for that tax year. This means that if you have already used up your annual ISA allowance, any money you take out cannot then be put back in during the same tax year.


    From 6 April 2016 Santander cash ISAs will continue to work as they do today, we will not be offering additional flexibility but some providers will be changing the way in which their ISAs work. Take a look at our information pages to learn more.
