Fixed Rate e-Accounts are designed for savers who:

are willing to lock away their money for a fixed term,
have a one-off amount to put away,
are looking for an interest rate that won’t change,
are comfortable with managing their money online.

Fixed Rate e-Accounts aren't designed for savers who:

might want to access their money before the end of the fixed term,
want to save smaller amounts on a regular basis,
want to manage their account by phone or post.

Our Best Rate Promise

Our fixed rate accounts benefit from 'Our Best Rate Promise', which means if we increase the interest rate for the account you have applied for at any point in the 14 days following the opening of your account, you will automatically receive the higher rate. If we reduce rates don't worry, you will still receive the same rate that you applied for. If our rates do change, you do not need to contact us, we will do everything and then send you confirmation of the new terms applicable to your fixed rate account.

Our Awards

We're proud to be Moneynet's 2023 Savings Provider of the Year, in addition to being 2022's Best New Savings Provider and to be highly commended in the Best Fixed Rate Cash ISA Provider category.
