The agency won a government pitch process for the FCO’s ongoing Know Before You Go campaign, which educates Britons travelling or living abroad.
As part of a brief it will take on the task of explaining how travelling England football supporters can stay safe during the World Cup, which earlier this year sparked riots as Brazilians protested about government spending on the tournament.
Consolidated director Liz Fay said: "It is about making people aware of what the FCO can and can’t do to help in certain situations, as well as saving consular time. Every year a certain number of issues and areas are identified and this year the World Cup is one of those."
Faye said Consolidated's work would target both male and female fans and would include a "high profile female sports person" as well as promoting a video on vaccinations and work with the Football Supporters’ Federation.
Consolidated replaced incumbent Grayling and will be working alongside marketing agency Bullet, which successfully repitched for the work.
