• Service update - due to planned essential maintenance our Online Service will be unavailable on Friday 28 January from 18:00 until Saturday 29 January 12:00.

  • Following the Bank of England’s decision to raise the Bank Rate by 0.15% to 0.25% in December 2021, Windfall Bond and Tracker Savings Bond rates increased by 0.15% from 1 January 2022. Tracker mortgages changed from 25 January and we have written to customers individually with revised payment details where the new rate exceeds the minimum rate (or ‘floor’) already applying to their mortgage. We will be considering our other savings and our variable mortgage rates after the Bank of England MPC meeting on 3 February. (Notice updated 19/01/22)

  • Please note that the Premium Saver (5) has now been withdrawn from sale. 
    If you have opened an account, you may add funds until 3pm, 7 February 2022, after this no additions will be allowed.

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.
