It is in the first stages of meeting agencies, and is looking to produce a long list of six, before cutting it down to three for a final shoot-out.
The whisky brand does not have an agency of record. The last TV work created for Grant's was for its Cask Reserves, which was created by McCann Erickson in 2002.
Its most recent work was a specialist promotional campaign that played on Capital Radio last year. It was handled by the company's media agency, John Ayling & Associates.
The agency picked up the entire £8 million William Grant & Sons account in March 2002. Before that, the business was split between John Ayling & Associates and Universal McCann.
The entire William Grant & Sons portfolio is branded under the name First Drinks.
Since 1996, the company has increased its turnover from £45 million to £180 million, for the year ending 2006.
