Monday 2 February - High call volumes

Due to the high volume of calls we're experiencing today, it's taking us longer than we'd like to answer your call. You may find the answers you're looking for in either our Mortgage or Savings FAQs.
If you still need our help, you can contact us by email (newbusiness@familybsoc.co.uk or mortgage.service@familybsoc.co.uk or savings.service@familybsoc.co.uk) or complete our callback form and we'll call you back at a time convenient for you. Thank you.
Savings customers - interest rates on many of our variable rate savings products will be decreasing from 29 January. We have emailed or written to you to let you know of how these interest rate decreases affect you. See our variable savings rate changes
