The Bank of England Base Rate.
The Bank of England reduced the base rate by 0.25 percentage points to 4.00% on Thursday 7 August 2025.
At Suffolk Building Society, when we respond to base rate changes, we consider the potential impact on both savings and mortgage members.
So, we’ll be making the following changes to our savings and mortgages accounts.
Last updated: Wednesday 10 September 2025.
How does this affect
my savings?
We’ll decrease the interest rate on most of our variable rate savings accounts, on a product-by-product basis, effective Wednesday 1 October 2025.
You’ll be able to find your new interest rates using the links below. We’ll contact you by email or post if the rate on your account is going to change.
If you have an existing fixed rate savings product, this will not be affected.
How does this affect
my mortgage?
We’ll be changing the rate of interest charged on the following mortgage products as follows:
- Standard Variable Rate (SVR) will reduce by 0.15 percentage points to 7.74%. Changes to monthly payments will come into effect from Saturday 1 November 2025.
- Base Rate tracker mortgages will reduce by 0.25 percentage points. Changes to monthly payments will come into effect from Monday 1 September 2025.
- Discount rate mortgages will reduce by 0.15 percentage points. Changes to monthly payments will come into effect from Saturday 1 November 2025.
We’ll write to you directly if this affects you.
