The Grown Up Chocolate Company has handed its consumer and trade PR account to Bell Pottinger Consumer.
The agency will position the chocolate-maker, who creates bars similar to those enjoyed as a child but with a 'grown up' twist, as a premium brand.
It will also drive awareness of the brand and its Tasting Club, a subscription service which delivers boxes of chocolates to homes around the country.
James Ecclestone, MD of The Grown Up Chocolate Company, said: "2012 is fast gathering pace and looks set to be a busy year for The Grown Up Chocolate Company as a brand, and an opportunity to get trade onside and consumers talking about our great quality chocolate. The feedback so far is incredible and a great endorsement to how we feel about the brand."
