The agency is believed to be the only participant in the process, which is not expected to affect McCann-Erickson's grip on the international creative account.
In the past, Black & Decker has shunned branding work in favour of product-led Christmas campaigns, which have helped to position Black & Decker products as the Christmas gift for husbands and fathers.
The development echoes the route St Luke's took to secure a brief with Sun Microsystems earlier this year. The agency was handed a branding brief for the computer giant, but this did not affect J. Walter Thompson's globally aligned deal with that advertiser.
Black & Decker spent just under £2 million in the UK last year. However, the majority of its advertising runs immediately prior to the Christmas holiday. The Trim & Edge, Esprit Drill and the Sandstorm Sander are its three most regularly marketed products.
Recently, Black & Decker appointed Boomerang Media with a view to launching a nationwide response drive aimed at increasing its 100,000-strong database.
The company had previously relied upon e-mail marketing to target existing customers.
St Luke's has so far had a torrid year in new-business terms, losing Fox's Biscuits to Phillipson Ward Longworth Camponi, Quorn to JWT and Travelocity to Miles Calcraft Briginshaw Duffy.
