The New Yorker's Adam Gopnik described the family's social status as "insecure upper middle, rather than from the very creamy top."
Lloyd Webber grew up in London's posh South Kensington neighborhood and attended the prestigious Westminster School. "Our family house was on a noisy, rundown block of mansion flats," Weber told The Wall Street Journal's Marc Myers in 2018.
Lloyd Webber's mother Jean taught music at a pre-prep school called the Wetherby in London, according to The Wall Street Journal. His father William served as the director of the London College of Music, according to The Journal. William Lloyd Webber was "happily obscure, making a living writing old-fashioned organ and choral music for amateur church choirs," according to The New Yorker.
Lloyd Webber's parents weren't supportive of their son's passion for musicals, however. Lloyd Webber's mother was more interested in the career of a family friend who was an aspiring concert pianist, the composer told The Journal in 2018.
