Duchy of Cornwall

The Duchy of Cornwall is a private estate established in 1337 by charter, with its income historically used to support the heir to the throne. Currently, this role falls to Prince William, as his father, King Charles III, ascended to the throne. The Duchy manages a diverse portfolio of land, property, and financial investments across England and Wales. Recently, the Duchy has been in the news due to reports that over 100 homes within its portfolio fail to meet legal minimum energy efficiency standards for rental properties, with one in five domestic lets having an EPC rating of F or G. This situation highlights ongoing challenges in property management and energy performance across large estates. The Duchy's financial operations and its role in supporting the heir to the throne make it a significant entity within the broader context of royal finances and public interest in the monarchy's assets.
