Adding to HGTV’s “Selling” franchise that also includes “Selling New York” and “Selling LA” is this series, which follows London’s elite agents as they attempt to sell some of the most beautiful homes in the world. Both buyers and sellers receive the royal treatment in one of the world’s most sophisticated cities, as agents look to make a king’s ransom brokering transactions involving everything from high-priced mansions and posh flats to prime properties in exclusive boroughs such as Kensington and Chelsea.
