Before moving into the castle in the 1890s, Wilbraham Tollemache, 2nd Baron Tollemache added central heating and electric light.[14] In 1922 a large scheme of afforestation was started on the Peckforton Hills,[14] and the resulting woodland has been granted the status of a Site of Special Scientific Interest.[15] Bentley Tollemache, 3rd Baron Tollemache, grandson of Wilbraham Tollemache, and his family left Peckforton at the outbreak of the Second World War in 1939.
