The Burghley House Preservation Trust Limited was established as a charity in 1969 by the Sixth Marquess of Exeter for the advancement of historic and aesthetic education and the preservation of buildings of national importance, and in particular the preservation and showing of Burghley House, Stamford.

The charity raises its income from charging an admission fee to visitors and running events and other commercial activities at the House. In addition the charity owns a significant investment property portfolio based around the Stamford area.

Wherever possible, the annual surplus is used to repair, restore and maintain the fabric of the buildings at Burghley House and the important collection of works of art and furniture that they contain. The Governors also carry out their activities with a view to conserving the environment of land and buildings owned by the charity.
