He was educated at Eton College, an all-boys public school in Berkshire.

[citation needed] In 1987 he succeeded to his father's titles and became the 3rd Baron Mancroft.

[2] Lord Mancroft has been married to Emma Peart, daughter of Thomas Peart and his wife Gabriel, since 20 September 1990; they have one daughter and two sons: In February 2008, Mancroft claimed that NHS nurses who had treated him at the Royal United Hospital in Bath were "grubby, drunken and promiscuous".

The hospital's Chief Executive, James Scott, called the accusations "damaging and distressing", and requested that the peer retract them.
