Summary Box

Account name Triodos Three Year Fixed Rate Cash ISA
What is the interest rate?
  • Interest rate is fixed at 1.00% tax free*/AER**.
  • Interest is calculated daily and paid annually in January and on maturity and added to the account.
Can Triodos Bank change the interest rate? No – the interest rate is fixed when the account is opened.
The 3 year fixed term starts from when the initial deposit is received. Rates may change between the time the application is made and the time the account is opened.
What would the estimated balance be after 3 years based on a £1,000 deposit? £1,030.30

This estimate is based on £1,000 being deposited at account opening, no further deposits or withdrawals being made and interest being added to the account annually and at maturity. This projection is for illustrative purposes only and does not take into account your personal circumstances.
How do I open and manage my account?
  • Can be opened by any UK resident aged 16 or over.
  • The account can be opened online only.
  • Sole accounts only, cash ISAs cannot be held in joint names.
  • The minimum opening deposit is £1 and must be made by electronic transfer from a nominated account or from an existing Triodos UK (non ISA) account.
  • In addition to making deposits that count towards the ISA annual subscription allowance, existing Triodos UK or other providers’ ISAs can be transferred in.
  • The full deposit must be received within 60 calendar days of the account opening, after that, no more money can be added.
  • There is no maximum balance, but the maximum current year’s subscriptions should not be more than the current tax year’s ISA allowance of £15,240.
  • The account can be viewed online.
Can I withdraw my money?
  • Withdrawals are not allowed.
  • Early closure or full transfer out to another ISA is permitted subject to a charge equivalent to 270 days’ interest. The charge will be taken from the account balance, so the balance transferred out could be less than originally deposited.
  • This ISA is not a flexible ISA.
Additional information A minimum of 30 calendar days before the fixed maturity date we will contact you to inform you of your options. At maturity the Account will automatically be changed to a 33 days’ notice Triodos Cash ISA, unless you advise us to do something differently.
