Cash ISA transfer FAQs

How do I transfer a cash ISA from a different provider to Principality Building Society?

You can transfer your existing cash ISA by completing our ISA transfer form when you apply. We’ll handle the process for you and contact your current provider. There’s no need for you to withdraw the funds yourself.
 

Will I lose interest or tax-free status when I transfer my ISA?

No. If you use the official ISA transfer process, your savings will remain tax-free, and you won’t lose your ISA status. Avoid withdrawing the money yourself, as this could affect your tax-free benefits.
 

How long does an ISA transfer take?

Cash ISA transfers typically take up to 15 working days from when your current provider receives the request. Transfer times can vary slightly depending on the provider you are moving from.
 

Can I transfer part of my ISA?

What if I don’t use my ISA allowance before 6th April 2027?

Your ISA allowance resets each tax year (which ends on 5 April). If you don’t use your allowance before 6th April 2027, you’ll lose that year’s allowance; it won't roll over into the new tax year.
