Media Reach Advertising will seek to raise awareness and increase take-up of tax credits for Revenue & Customs.
Meanwhile, the DCSF campaign will focus on encouraging parents to use early-learning for three-to-four year olds and wider childcare services for older children.
PR activities will include roadshows around the country, which will feature Revenues and Customs and DCSF delivering their messages side-by-side, the first time two government departments have come together it this way.
The Central Office of Information managed the pitch process. The campaigns will launch in January 2008.
