Santader Fixed Rate Isa Maturity Options - MoneySavingExpert Forum Does anyone know when Santander contact you with maturity options? I have a one year fix maturing in 10 days and haven't heard anything There's an option to 'upgrade' the isa account: would I use this option now, if I want to open a new fixed rate account with Santander once the account has matured? Appreciate any advice shared experience
