Key to a Fortune is a "transformational show" that reunites families with homes as well as relatives they didn’t know they had.

The series reveals that each year in the UK, millions of pounds worth of vacant homes are sitting unclaimed. These hidden treasures belong to ordinary people, who are unknowing inheritors to estates that were once owned by a distant relative who didn't leave a will.

Throughout the six-part series, we will meet some of these inheritors as they discover their secret family history thanks to the new home they have inherited.

Kate Thomas, Commissioning Editor, Daytime and Features at Channel 4 said: "In Key to a Fortune we are going to make dreams come true as we surprise members of the public with unexpected windfalls, whilst also taking them on an emotional journey to meet relatives they never knew they had. 

"I am thrilled to commission this distinctive new format, which I am confident will be a big hit with our viewers."
