Apparently British life peers' wives get the title "Lady," but husbands don't get anything at all. Sexism! Sexism!
Debrett's - The Peerage: Dukes, Marquesses, Earls, Viscounts, Barons (and Life Peers): The Life Barons' wives rank as Baronesses, and are entitled to the prefix of 'Lady', while their children, and those of Life Baronesses, are styled 'Hon' for life and hold special precedence. The husband of a Life Baroness, however, does not receive any special prefix or style by virtue of their wife's title.
