Currently they store the from and to addresses of all emails sent, as well as the subject line, date stamp and IP address of the machine connecting to the server (usually your router, but not always). Encryption makes no difference as you can't encrypt the headers since obviously the server needs to read them.
But, if you are using say, Gmail over a https connection, how would UK find out the headers in that case?
Your connection to GMail is encrypted, Gmail to destination(say, Hotmail) could happen outside UK, and destination(Hotmail) can be viewed over an encrypted connection again
