    Managed Mortgage Rates and Discounted Variable Rates

    From 7 February 2026, we'll be decreasing our Managed Mortgage Rates (MMR) by 0.15%. All on-sale discounted variable product rates and other details, including representative examples displayed on our website, have been updated to reflect these lower rates.

    We will shortly be writing to existing customers who have been impacted by this change, with details relevant to them.

Our MMR history

Details of our Managed Mortgage Rate (MMR) history.

The Managed Mortgage Rate (MMR) is a type of mortgage interest rate that you are most likely to go onto after your introductory fixed, tracker or discounted deal ends. 

We choose what the MMR rate is and it does not track the Bank of England Bank Rate. Your MMR depends on whether we calculate the interest on your mortgage annually or monthly. The MMR you’ll pay also depends on what type of mortgage you apply for.

The table below details any rate changes that have been applied to the Family Building Society Managed Mortgage Rates since they were launched.
