Yes. We can move the interest rate up or down at any time. Our Savings Account General Conditions explain when we'll do this.
If we increase the interest rate, we’ll make details of the rate change available in branch, on the phone and on our website, within 3 days of the change. If we decrease the interest rate, we’ll let you know personally 14 days in advance. You can close your account without charge within 30 days of the change, and at any other time. We may not do this if you have £100 or less in your account. Instead, we may tell you about it by making details of the change available in our branches, at tsb.co.uk and through telephone banking.

Important Information
*Variable means the interest rate on your savings can change. The rate can go up and down. If it goes up, you earn more interest. If it goes down, you’ll earn less interest, but we’ll tell you before this happens. If you’d like to know more about what might happen to our variable interest rates when the Bank of England changes the Base Rate, head over to our Popular Questions page at www.tsb.co.uk/savings/
The Annual Equivalent Rate (AER) shows what the interest would be if the interest was paid and added to the account once each year. It lets you compare savings accounts easily. Gross rate means that credit interest is paid without income tax being deducted. Tax-free is the contractual rate of interest payable where interest is exempt from income tax.
You need to be 16+ and UK resident to open most of our savings accounts with the exception of Savings Pots and TSB ISAs. For children under 16 please see specific pages for opening procedures.
