How can I top up my cash ISA?

To top up a Triodos cash ISA you can:

  • Make an online payment from another account (either an account with another provider or another Triodos account that allows withdrawals).
  • Send us a cheque if the Triodos cash ISA you want to top up accepts cheque.

The following accounts do not accept cheque payments:

  • Online Cash ISA
  • Fixed Rate Cash ISAs

If you want to deposit a cheque, please post it along with your account details or a paying-in slip to: ‘Freepost TRIODOS BANK’ (no stamp required)

The Triodos Bank sort code is 16-58-10 and you can find your Triodos cash ISA account number by logging in to your account online or via the Triodos Mobile Banking App, or by checking your bank statements.
