Clandon Park House

Clandon Park is an early 18th-century grade 1 listed Palladian mansion in West Clandon, near Guildford, Surrey, England. It was long a seat of the Onslow family. It has been owned since 1956 by the National Trust. The house was substantially damaged by fire in April 2015, which left it “essentially a shell”.

The Fire on the afternoon of 29 April 2015, a fire started in the house’s basement, and quickly spread to the roof. At 16:09, Surrey Fire and Rescue Service received an emergency call, and the fire was subsequently attended by a total of 16 fire engines and more than 80 personnel. While fire fighters tackled the blaze, National Trust volunteers were joined by conservators in salvaging furniture and works of art. Items were first stored on the lawns then placed in bubble wrap and sent to a local storage unit. The fire and rescue service remained at the property until the fire had been fully extinguished and then began an investigation into the cause of the fire.

Cause: Investigations have concluded that the fire was accidental and the probable cause was a defect in an electrical distribution board located in a cupboard in the basement.
