William Hill adds The Black Hole, Elmwood and Blue Chip to its agency roster.

The Black Hole has been appointed to handle online and offline direct marketing for the bookmaker, replacing Prego, after coming through a pitch against an undisclosed number of agencies. Meanwhile, Elmwood is believed to have been appointed to work on in-store design, with the task of giving William Hill's retail outlets a revised look and feel.

A pitch for sales promotions and partnerships is ongoing, while Manchester's Blue Chip is understood to have been handed project work for the firm.
