We're writing to customers we've not heard from for a long time who still have savings with us.  If you're one of them, you should've received a letter telling you what you need to do to reactivate your account.  If you've not had a letter, you can find out what you need to do here.

To reactivate your account, either:
Call us on 0345 7000 777*.

We’ll carry out an electronic ID check when you call. If you have your account number, it'll be easier for us to verify you, but don't worry if not. If the check is successful we should be able to reactivate the account for you there and then. If you need to send us some additional ID before we can reactivate your account, we'll tell you on the call. 
Visit any Yorkshire Building Society branch or agency. You won’t need an appointment. Our branch and agency finder will give you details of all locations, along with up-to-date opening hours. When you visit please bring along one piece of ID that confirms your name and another piece of ID that confirms your address, so we can verify your identity.
