Baking for Britain offers an access-all-areas look at the popular high street bakery, from the kitchens to the boardrooms.
The fly-on-the wall show, produced by Mentorn Media, will feature some of the 20,000 staff who made the company a success.
Mentorn Media's Executive Producer Neil Grant, said: "What a fantastic opportunity and privilege to make a fun access series behind the scenes with the nation's high street icon - this will be popular television at its very best!"
Siobhan Mulholland, Sky's Commissioning Editor for Factual programming, added: "This is going to be a warm-hearted and fascinating insight into a much-loved British institution.
"The access is impressive; the cameras will be in the shops, following the delivery trucks, following characters, even in the usually confidential tasting labs. It will be a television treat for Sky customers."
Baking for Britain, an eight-part series, will air next year.
