June 26, 2026 07.00 Europe/London By Julian Clover


Channel 4 has partnered with consumer and market intelligence specialist CACI to offer advertisers enhanced postcode-level audience targeting across its advertising inventory.

The broadcaster’s new Geo Mapping tool combines CACI’s geospatial intelligence with its Acorn consumer segmentation data, enabling advertisers to target campaigns based on location, demographics, affluence and travel catchment areas.

The platform is designed to help brands identify high-performing postcode sectors aligned with campaign objectives, including high-net-worth households and specific interest groups. It also supports location-based campaigns by identifying audiences within defined drive-time or radius catchments.

CACI’s Acorn classification system uses more than 800 variables to segment every UK household and postcode, providing advertisers with demographic, lifestyle and market intelligence to improve campaign planning and reduce wasted impressions.

David Amodio, Head of Sales at Channel 4, said: “By partnering with CACI, Channel 4 has created the market’s most sophisticated Geo Mapping tool, enabling advertisers to create highly targeted, advanced postcode sector campaigns and get even closer to hard-to-reach audiences.”

Cara Bramwell, Director of Consumer Insight at CACI, added: “Combining CACI’s breadth of insight into the UK consumer with Channel 4’s reach and popularity creates huge opportunity for advertisers, allowing for a hyper-targeted approach that will support more effective campaigns and deliver better outcomes.”

Healthcare provider Nuffield Health was among the first advertisers to test the platform. Marketing Director Marsha Riley said the tool enabled the company to target only postcode areas served by its gyms, helping optimise campaign budgets while reducing wastage.

The partnership is the latest addition to Channel 4’s advertising technology strategy, following recent integrations with major programmatic buying platforms and the launch of new connected TV advertising products.
