The team's "kettle" spot for Robinsons was judged the top work by Alasdair Graham, the creative partner at Ogilvy.
The runner-up in the awards, held in association with Campaign, was Martin Galton of Hooper Galton for his Nando's "BASTE" work.
The winning ad pushes Robinsons as a winter drink, highlighting that it can be added to hot, as well as cold, water.
Graham said: "When the water in a kettle reaches boiling point, it roars and howls like a gusty wind on an autumn day. So, at this time of year, drink Robinsons made with hot water. The result is a fun bit of radio, with a simple message attached and a generous amount of room left for the listeners to do their thinking for themselves."
