The new business will draw together specialists from iProspect, Isobar and Dentsu Aegis Network Sports and Entertainment, as well as Carat.
The agencies will create and manage an overall consumer ecosystem that better aligns paid-for media with engaging content, amplified by social media, and driven through a powerful PPC and SEO strategy.
Carat’s recent work with Wickes has included partnerships with Absolute and Talksport. On Talksport, the retailer is title sponsor of the 'Colin Murray and Friends' mid-morning weekday show.
Carat was awarded Wickes' media planning and buying account in 2011.
Matthew Gaunt, head of brand communications at Wickes, said: "We’ve enjoyed an excellent relationship with Carat over the last three years.
"The team demonstrated the business benefit of better aligning our above-the-line activity with engaging content and best-in-class digital thinking by using the talent across DAN, making them the obvious choice to work with across social, PPC and SEO."
