Following the 2008 financial crisis, the UK government put reforms into place for banks to separate corporate and private customers. This is known as 'ring-fencing'. This means that our sort code and account numbers are changing because, as a financial institution, our clearing bank needs to move the Family Building Society to their corporate division.

As a result, we have been issued with a new account number and sort code. Our new account details are ready to use, so if you are planning on setting up a new payment or are a new customer, please use the new account details listed below:

Our new bank account details are:
New sort code: 40-02-50
New account number: 21397400 

Please remember to quote your 10 digit Family Building Society payee reference number as the 'Reference' when sending the payment to the Family Building Society.

Important information for savings customers
If you wish to make payments into your Family Building Society savings account(s) via standing order, Faster Payments and/or transfer money online from your bank account into your Family Building Society account, you will need to change the existing Family Building Society account number and sort code. While we will be able to accept payments using the existing account well into 2018, they will need to be changed by 1 January 2019. That's why we recommend you amend the payment details you use to send payments to us at your earliest convenience.

When using Faster Payments, you may notice that some banking providers may have redirected your Faster Payment to the Family Building Society new account details automatically. You may also see, when using internet banking, that the Family Building Society account number has changed to the new details, which are sort code, 40-02-50 and account number 21397400. This is entirely normal and you do not need to make any further amendments to your payment instructions.

Important information for Windfall Bond customers
Each Windfall Bond account must hold £10,000 exactly. If you wish to add more than this you may apply to open other Windfall Bonds, subject to the account meeting the £10,000 balance requirement. There is no limit on the number of Windfall Bonds you can hold with us.   

Important information for mortgage customers
Mortgage customers with an existing direct debit do not need to take any action - your payment will be redirected to us automatically. However, if you would like to make overpayments on your mortgage separately, please use the new account details above.

If you have not used internet banking before but would like to set up a new payment to one or more of your Family Building Society account(s) via internet banking, please use the new account details above.
