Base Rate Tracker

With our Base Rate Tracker Savings Account, we do all the hard work for you by tracking the Bank of England base rate — so if it goes up, the interest rate we pay on your savings will also go up by the same amount.

How it works

Your interest rate will depend on your balance and whether you have an eligible Co-operative Bank current account. It will go up and down with the base rate.

  • Current account customers benefit from an interest rate of 1.25% to 3.50% (gross/AER variable).

  • Non-current account customers benefit from an interest rate of 1.00% to 3.25% (gross/AER variable).

Existing customers can apply online or in our app

About the interest rates

  • Your interest rate will track at a variable margin in relation to the base rate, and could be above, equal to or below the base rate – we’ll update the interest rate within 14 business days whenever the base rate changes.

  • We’ll automatically change your interest rate – if you open an eligible current account we’ll increase it, and if you no longer hold an eligible current account we’ll decrease it.
