The awards has hired the agency for PR surrounding the show this October, with the possibility of an ongoing three-year deal.
THC won the brief after a three-way pitch. Production company Indigo Television retained AMV Advance last year for the awards, before which MacLaurin worked on them for four years.
THC co-founder James Herring said the campaign would be handled at a national and regional level, with three main stages: publicising the long-list, short-list and the event itself, to be broadcast live on ITV1 from London's Royal Albert Hall.
The awards, which last year included a gong for Big Brother presenter Davina McCall, are voted for by the public. Viewers can vote by post or text message via voting partners Royal Mail and Vodafone.
