Is this the best cash ISA for you?

  • Spread your tax-free ISA allowance across multiple ISAs with Paragon’s ISA Wallet
  • Quickly transfer your existing ISAs from your other providers
  • Manage your account easily online or by post
  • Early withdrawals are subject to penalty, you can’t make additional deposits
  • Your interest rate won’t change during the fixed term
  • If you’ve already invested in an ISA this tax year with a different provider, you’ll need to transfer this years subscription in full
  • There is a 270 days’ interest penalty for closing your account before your fixed term ends. So, if you close your ISA in the first 270 days, you may get back less than you invested.

Since opening an account with you, Paragon has become one of my favourite banks. Not only was I impressed with your ISA rates, but I found you to be a very savvy internet bank, providing a product that I want simply and efficiently

John Cattanach

The transfer was much quicker than anticipated. I did all the paperwork online, including the application and transfer form and Paragon Bank took it from there. The account was easy-to-set up and the system is easy-to-use

Greg Haycock

The ability to request the transfer of funds from my previous provider as part of the online application process felt like a real step forward. In the past, with other banks, I’ve always had to fill out a paper form to do this part of the process.
