The 12th Duke of Devonshire, Peregrine Cavendish (b.1944), succeeded his father in 2004. He married Amanda Heywood-Lonsdale (b.1944) in 1967 and they have three children, William, Earl of Burlington (b.1969), Lady Celina (b.1971) and Lady Jasmine (b.1973), and ten grandchildren.
During 2005-2018, a major £32.7 million 'Masterplan' was undertaken to make improvements to the house. Informed by painstaking research and analysis, this work ensured that the building's essential services were brought up to modern standards, improved accessibility, and energy efficiency, and included extensive external conservation work to the stone, roof, and other structural elements.
Looking ahead, the Duke and Duchess are joined by Lord and Lady Burlington who play an active role in delivering on Chatsworth's commitment to creating life-changing opportunities through nature, culture, and learning for visitors, colleagues, and local and wider communities.
